Here's my list o' pain:

Pair of Klee Sequencers

Thomas White Low-Pass Gates

Serge/Banalogue VCS Got the PCB. Gotta make the faceplate.

ADA Flanger Clone Still gotta talk to Luka about those dope-ass faux MoogerFauxger cases.

JH Triple Chorus

Fonik's Attenuverting Mixer

If anyone is making any of the above in Euro or Frac, lemme know. Maybe we can get the faceplates done together.

X0XB0X build

Replace AC128 xstrs in my Fuzz Factory clone and seal that biznatch back up.

Fix and modify my Moviola amp The Postal Worker literally dropped it right in front of my whilst behind the desk when I was going to pick it up from them. Sounded bad... I opened it up at home and 1/2 the tubes where shattered and 'all of the vacuum leaked out' (love that joke). Plus, some stuff was totally dislodged. Losers...


neandrewthal
Hey no fair, you started the thread while I was making my epic post, but you didn't even add anything yet hihi(edit: ok, now you did) I'll just move my post here.

aw, drew I think that post was number 30.000! Awesome!

Can we get a higher-res image of that mockup? I reckon even a very large gif in monochrome shouldn't be too big, filesize-wise?
neandrewthal
How about a PDF? Then you can zoom in as much as you want without losing resolution.
wetterberg
Cheers! got any shots of your first cabinet, mate? As you know I've got a hunkering for CGS these days, and it's pretty difficult to get an overview from your videos smile
parasitk
Umm, everything that was on my list for 2008. d'oh!

Five T. White 292c LPG boards, finish Peake's dual 281, Woggle #3, some Blacet kits... we'll see what else.

I'm still gathering tools so I can start this whole DIY thing (soldering station is next! lol )
Kent
Hey, sorry; Drew.

I threw it up here as a place holder so that we wouldn't have 3 or 4 guys starting epic "DIY 2009" threads. I then went back and started adding the projects. Then my friend hit me up on Skype and I had to stop. Will add the rest shortly.

BTW, that's a lot of shit you have to build. Good thing that the year has just started!

Stuff I've got to build/buy for cabinet #4:
Primary goal . . see if i can resist doing a 4th cabinet!!! nuts
plord
Right then, let's queue it up.

Critical task: REBUILD STUDIO once the basement reconstruction work is done, likely sometime in February.

Important task: Build third large cabinet, probably another L-shaped brute with 8 or 10 on the flat and 12 or 14 on the up. This one will eventually be dedicated to sequencing and clock/CV mangling.

Other important task: Get mounting rails and wire up that Power 1 PS to drive the 12 module MOTM cabinet I got from Hans. Hell, I have fully functional MOTM 440 and Oakley Superladder filters just SITTING HERE.

Plus I'll tackle this updated (in bold), randomly ordered, list of known projects:
* Klee - Cable Nightmare correction in progress.
* MOTM-700 dual VC switch ( 2 ) - Stuffed, wiring the 300 sized panel now.
* Yusynth Diode Filter - FAILBUILT. Debug or mount above workbench as a warning to self and others.
* CGS Sequential Switches ( 4 ) - Panel stuffed, one board stuffed.
* Fonik 5 channel Mixer/Attenuverters (2) - Have everything including 300 panel
* Buchla 281 AR Envelopes ( 8 ) - Have everything including 300 panel
* JH Tau Pipe Phaser - Have everything including MOTM panel
* JH Krautrock/Schulte Compact A Phaser - Have everything including MOTM panel
* JH Solina Chorus - Have PCBs and BBD chips and MOTM panel
* Wogglebug v3 ( 2 ) - Have everything, have VCR for CV of Woggle Time, have MOTM Panels with proper mod bits
* SN Voice - Have everything including MOTM panel
* MB808 - have PCB, colored LED-switches, pots, rare ICs. No case, no panel, no giant box of parts.
* BYOC Tri-Boost pedal - have everything
* BYOC Chorus pedal - have everything
* BYOC Analog Delay ( 2 ) - have everything and spare VCR to hack delay time.
* BYOC Tremolo - have everything
* John Fromel Lush Stereo Chorus (DC-2 clone) - Have pcb and parts, no panel or panel hardware.
* MFOS Quantizer ( 4 ) - have PCBs, parts in mail
* MFOS stereo mixer ( 2 ) - have PCBs
* CGS LED drivers ( 16 ) - Have boards, BC547s, resistors; waiting on LEDs and 16 opportunities to add an LED to a module smile
* Thomas White Buchla 292 clone ( 2 ) - have PCBs and MOTM panels
* Cynthia Quad LPG - have partially stuffed PCB. Thinking this one will go Frac.
* Mankato Filter - Have everything and
* Modularized MF-101 project - Adapt this bare board for 15V use, sort out wiring, pots, jacks, etc. If it works, sabotage my working pedal and throw both filters into a rack unit as a pseudo-Mutator.
* Unannounced Thingy - Panel design complete. Mwah hah hah.

PLANNED BUT NOT YET PURCHASED/AVAILABLE
* CGS Stompbox Adapter (who bought Ken out? Fess up now...)
* JH Dimension D clone
* Fonik's stereo PS3100? But at that point I think we ARE talking about a fifth cabinet, and that's...threatening. Even to me.

DONE! applause

That shit is perfect!

General: Need to design a layout here - I still may elect to make a case simply for diy, then power that off a +-15v PSU, and then a separate case just for euro. Rails are in the mail.


Power-One PSUs - sitting in New York at my friends house... awaiting shipping here.
BrideChamber VCR x4 - have parts and PCBs, will solder up tonight!
CGS VCO - have parts, awaiting pcb from CGS - in the mail. Still need to decide how many functions to put on the panel! This one has. it. all! eek!
CGS Steiner Synthacon Filter Clone - have parts, awaiting pcb from CGS - in the mail.
CGS Master Divider x2 - have parts, awaiting pcb from CGS - in the mail.
CGS Tube VCA - have parts, awaiting pcb from CGS - in the mail.
CGS Dual Utility LFO x2 - have parts (except DPDTs d'oh!), awaiting pcb from CGS - in the mail.
CureTronic 150m - ships fully populated, need to design panel layout.
CureTronic mini-VCOs x2 - ships fully populated, need to design panel layout.
CureTronic C601 Tool (gate delay, bissell slew,cv sourcex2, inverterx2, portamento) - ships fully populated, need to design panel layout.
- and then quite possibly the CureTronic Decade Counter (mmmmm, inhibit Drunken Homer Simpson )
and finally:
Breakout board for Doepfer a-110 (lin FM and soft sync)
Doepfer 143-1 speed switches - Need caps.

1. Fix Ian Fritz Waveshaper. I think I reversed the power on it and blew out some things. Hardwire the power chord since I reversed the pins when I made it.

Done, fixed. I had burned a TL chip or 2. I replaced what I had on hand and it works now.

2. Ian Fritz Dual Threshold/ Gate/ Trigger/ Sample and Hold. Have the kit.

Done

3. Low pass gate. I have 4 of the electromusic group buy boards, and one from a different pcb layout that was home etched. I want to build a single module first and then maybe a quad.
One board populated 3/16/09
One LPG finished. Sounds sooo goood!!! 3/17/09

4. Buchla 281 clones. I have 4 of these boards to do.

5. Bananalogue VCS. I have 2 of these boards to do.
begun 3/16/09

6. Tube VCA. This will actually probably be #2 finished since I have everything finished except the panel wiring.
Done. I need to go back and do the bias mod later, but it is done and works.

7. Finish my studio. I need to do some dry wall work and put up accoustic treatment.

I would like to do more, but I'm sure I'll be lucky to finish all of that. I want to breadboard a simple module from a schematic. I want to etch, drill and build a module to completion on my own from a published pcb layout. It seems reasonable to do all of that in a year, but life has a way of eating up time.

8. Add 2/19/09 Blacet Mixer/Processor... Done

9. Add 3/16/09 MOTM Suboctive Multiplexer with Tellum daughter board. Main board populated.
Leisure Cove
To do: CGS Simple Wavefolder-- my first DIY module!!
strategy
I'm not seeing any/much newbie representation on this thread. Here's my new-to-the-forum list of backlog -with DONES for updates:

Almost Finished
- Maestro Ring Modulator clone - needs to be calibrated and mounted DONE! This project was stupidly difficult, crazily designed pcb layout with loads of important info left out of the documentation. The first project I ever started now brought to completion, enclosure and all
http://picasaweb.google.com/lh/photo/f8L_kUgntRflF8-7cw2Sgg?authkey=eD PAXTNPtlk&feat=directlink

- Parareil Coron DS8 clone
- Dan Armstrong Orange Squeezer compressor pedal clone DONE!
- Oakley TB3030 (old old version)

Halfway Done-ish
- 4ms Noise Swash DONE! Except the LED won't work even after extensive troubleshooting :-)

On the pile
- GetLofi Atari Punk Console DONE!
- TH Mega Percussion Synthesizer
- Neural Agonizer
- MIDIbox SID
- re-build my Doepfer Pocket Electronics midi controller into a new housing

Rescue modules- bits and pieces from a friend -
- re-house and build PSU for a Buchla 100 series band splitter clone
- Buchla Matrix Mixer clone - panel/knobs
- Ian Fritz Double Well Chaos mostly populated[img][/img]
Luka
well ive got HUGE shipment of parts rolling up soon so im setting some deadlines for projects. Still need to order a bit more for my first deadline stuff.

end of MARCH
808 (w/o case is fine,, just want the circuit built and tested)
Box'o'trix (1/2 built)
2nd CGS VCO
dual291 (still to be etched and built)
quad292 (needs to be built)
quad281 (needs calibraiton and panel)
wavemult fixed (fixed!!.. needs panel and 5/6 pole mod)
2nd dual TH-vca1
Digisound quad lfo
Tau Phaser (90% populated)
Krautrock Phaser
Klee fixed

AND i have all my panels for all my modules cut and ready

in the mean time here is my panel design for my boxotrix

plord
Quad VC Switch (two x MOTM-700 behind a Wiard panel) complete, pix to follow. Hit a slow patch since.

Did order two Fritz AD/AR Envelopes for the (suddenly growing) MOTM rack, along with parts for the Cynthia quad LPG and MFOS Quantizers.

I keep looking at the Klee rebuild with sadness and a little self-hate. Probably better get that one out of the way next.
neandrewthal
I've been piling up hardware and PCB's like tommorow is non-piling up hardware and PCB's day. Now I'm up to my ears in BOM's trying to make a spreadsheet that tells me what I need to order for 80 modules help Between this, waiting for the mailman, putting together a new cabinet and filing down all my panels for a perfect fit it's gonna be at least a couple more months until I get to the fun part very frustrating
plord
Oh god, cabinets. Don't remind me. I am getting close to the point where I have more modules outside the cases than in them. Problematic. and my last attempts at woodworking convinced me that I kind of suck. Or, maybe, my tools suck, and I'm not willing to invest in another round of better tools.

But yeah. Cabinets. A problem.
Luka
woot fixed my wavemult

yeah cabinets is a bastard isnt it
ive handed my rough design concpt to my housemate who will hopefull have time to weld it together in the next month. gotta work out how to put rails in it though confused
neandrewthal
Haha, watching other guys botch their attempts at cabinets convinced me it was sheer luck I was able to make my first one work, and I'm afraid to try again. help
Kwote
balls to the wall hihi

i'm still collecting pcb's and i'm on hiatus from that. i figure i should cop the last bit of blacet's kit line up and hopefully save enough to put in a wiard order before i really bare down on all the other stuff.

but once i do get going i'll have over 50 projects to work on d'oh! love
consumed
i really dont want to tie myself up this year building more than playing.
so im keeping my list somewhat light. it will probably be all euro.

- build 6u eurorack expansion IN PROGRESS
- finish 2nd attenuverter
- 2 buchla 281 clones
- 2 lowpass gates
- 1 matrix mixer
- boss dc-2 clone

i have a 2nd klee and a thin stack of JH projects that have no timeline.

i keep it minimal: 1x10s lumber, 20 1/2" (plus a noodge) for top & bottom, 16u for the sides... nailed together, then 4 angle irons screwed to the inside for stability. then add 2 predrilled side rails from raxxcess, recessed 3/4 inch. no sanding, no paint, fully functional.

the modules are a different (obsessive) matter: frinstance, all resistors are oriented so the multiplyer band is on the right or top...

Kent
Wow! You be on a roll! Rock on.
krelnarb
My list is mucho modest, But I am happy to say I've finely plugged in the Weller over the last few week to built some of this stuff I've been collecting:

Last weekend I finished my Blacet Quad VCA and a Final Filter. I also populated 3 Evenfall VCO PCBs I got back 2001. I need panels for those. Those will be in the Frac format.

The weekend before that I finished my Blacet Binary Zone and a Scanner/Switch pair.

This weekend I'm going to try to finish a Blacet Frequency Divider and Time Machine. And after a Klangwerk and Miniwave. And some where in there a MOTM-410 and OMS-410 set I've had for a bit.

Incomplete stuff I have either PCBs and/or panels and/or Parts (I got a new Mouser catalog today. This is a good sign):

* Larry Henry 822 and 831 voltage switches

* Oakley Superladder2 and Multifilter2 (I've had these awhile too) I'm building the Roland version of the SL2.

* A Klee and a MFOS 16 step. I think I'm going to build these in the MOTM rotaries format. A pair of M-185 sequencers also in the MOTM format, and a CVS. I heart SEQUENCERS!

I also have all the stuff to finally rack my Oberheim TV-1 and be free of the keyboard, all jacked out in Molex land.

And I have a Paia 9700 system to finish. I already have one 9700 (that and a Darkstar was my first modular set up. Good times) I want to throw both 9700s in a 6U, ditch the MIDI2CV8s for a random voltage source and a pattern generator and I'll have a nice 'jump on the bus and take it to a party' rig.

I think I can get this all done before the summer. Crap, I still have to get cases for all this stuff!

Cheers y'all
rezzn8r
I haven't touched an iron since college, but to get warmed up, I've ordered a thingamakit and a few of tom's 606 mods from analogue solutions. after that I might try something with more meat...
krelnarb
This weekend I finished the Frequency Divider and the Miniwave (How did I get this far in life without a Miniwave? I can't stop messing with it.)

Next weekend either the Klangwerk or the Time Machine (both?) but I've now run out of rack frame space. And money. So they'll sit on the shelf till next month d'oh!
Luka
ok got 8 pcbs of buchla and 2 jurgen haible pretty much rocking smile



and got the panel design rolling for the krautrock phaser
ill attach this to some alu i have lying around as a test and see how it works




i also fixed the problems in my wavemultiplier, man that thing sounds killer

also half populated my mankato and continuing on my 808 and boxotrix

Nice work! Do you have bridechamber's version of the Wave Multiplier/RRM?
I can't work out how to wire the pots.

p.s. Instead of nicknaming it Shulze, you should've called it the Grobschnitt!
Luka
no it was an original cgs board

what are you stuck on? i also have a RRM
Roycie Roller
Just the wiring of pots. The legending of the ins & outs, & the abbreviations on the Bridechamber version are different from Ken's notes/ schematics on his site, and there's no additional notes on the Bridechamber version that i've been able to find anywhere. But i haven't sat down to really nut it out yet...I need to get more jacks & pots before continuing my stockpile.
I finished the Jerkster & Wogglebug, those two work amazing together!
Luka
oh fair enough, best ask scott at bridechamber about it
neandrewthal
Good stuff. Can't wait to see the finished product.

My 2009 work is officially underway with a new gameplan. I was just getting ready to buy all the 6000 and something components I need, so I could build any module I choose, one at a time, but due to unforeseen financial difficulties that's not an option anymore. Now I'm just populating every pcb I have with whatever leftover components I still have in stock. Hopefully by the time I run out I'll have enough cash to pick up the rest of the parts I need to actually finish something.
criticalmonkey
not glamourous but...
built a 19" single space rack multi with 14 1 x 1/4 and 3 x 1/8 sets -
finished a cellular automata video synth - though not in the originally planned euro format - don't want to waste valuable space - demo one day soon - but really a great bleeper for 50 bucks - http://www.makershed.com/

taught my son to solder too

next few months are finishing a few pieces of music then i'll be ready for some studio furniture building and more diy
neandrewthal
And here's my first working module of 2009 hyper

I was putting off a joystick module for a long time, trying to decide whether I want it on a modular panel or in a standalone box, how to power it etc... Then it hit me: why not throw 2 of them in a temporary box and just wire each pot lug to a jack? 30 minutes later, here I am:




I had a fucking blast with it tonight crossfading between 8 different CV/audio sources.

I'm eventually gonna make a fancy box for it and some multiples/momentary switches. Hell, why not some toggle switches while I'm at it? And normal some 5v references to the inverters in my modular so I have some nice steady sources of +/-5 without trying up other modules.......Uhoh, feature creep Rage!
plord
I finished the Klee partial-dismantle last week, removing my buggered wiring as well as any strap-ground related to it and a pair of fried LEDs.

Also wanted a quick win, so threw together the BYOC Tremolo pedal last night, trivial build, worked first try, go me!
Norman_Phay
I got back into building, having been a bit burned out with it (and everything else TBH) over the last couple of months. Finally assembled this:



....which is an Oakley "Equinoxe" phaser and an Oakley Octal Resonator, behind a sort-of-Wiard 300-height, but slightly narrower panel - after I sold my Wiard rack ears and made a set of horizontal rails in my case, I had that much space in the upper row. thinking of buying a dual quantizer from Bruce D and mounting it behind a similar panel in the bottom row. Next up is a dual Fonix attenuverter mixer, then maybe the Ryk M183 sequencers.
Norman_Phay
Equinoxe phaser is so damn good.
zthee
First post! Yay!

Here's my current list:

Boards I've populated, and now need a front panel:

CGS Digital noise
CGS Saw pitch shifter
CGS 4 stage Programmer / Sequencer
CGS VCA x 3
CGS CV Cluster
CGS Quad Logic
CGS Pulse divider
CGS VC Divider
CGS PT2395 Delay
CGS Sequential switch (Doubt it'll ever make it to a panel..)
TOP Quad 281 Function Generator

Half populated boards:
Haible FS-1A
CGS Wavemultiplier
CGS Gated Comparator

Not even started
CGS ASR
CGS VCO
CGS VCA x 4

I'm a total CGS whore!

SlayerBadger! w00t

Okay, a couple of questions:

a) I know you're an experienced diy wiz, but how difficult was the Programmer to build, on a scale of 1to10?
b) Ingenious solution with the "sub-frame" holding up the boards inside, while only having 4 front panel screws... I'm so stealing that idea. Where did you come up with this? And do you teach a class? hihi
zthee
The programmer isn't that hard to build. It's just that it's very fragile when it's done. If i shift the wire running between the first and the last board connecting the busses it can go haywire. I think the hardest part of it is that it's "capacitance-driven" (I think?) - so if you have poor solder joints, they will be a problem! The wires connecting the J, G and H busses between the first and last board has been a head ache for me. I've strapped them down, because if they move they mess upp the stages... It's kinda hard to explain. I'd say give it a try! It's a great module! I'm planning on doing a 8-stage version on panel no. 4.

The subfram: I stole the idea! grin http://www.icb.se/araya/serge.html (I actually hang out with that guy every wednesday - discussing modular synthesizers, DIY in general and Serge in perticular) - Once I got inspired to do a Serge style panel I started digging in anything Serge (I think I've seen everything Serge on the internet so far.. but I hope not!) and found alot of good ideas to steal!
wetterberg
wonderful tips! thanks mate. And the best of luck on panel 2, I hope you'll share that process with us as well!

very nice ZT!

Since I dont have too much freetime to spend on DIY, I have to keep it low:

finish the last bits on my modular-case:
-missing on-off switch
-manual gate is not working as it should

in addition i guess i am in an urgent need of a second case - so thats gonna be a 2x64TE case with enough space for a spring reverb tank. got some 16" (i guess) rails from proma some time ago. just need to figure out how to power the whole thing.

modules:
wogglebug#3 (stuffed and soldered, needs hardware+faceplate)
chaquo (same as above)
µcapps midi-cv (not sure if i need that one, dont have a midi source anyway)

mods: tr-606 complete modification.

misc: maybe a second kid w00t

I haven't built a fucking thing yet, mostly because I still have to get so many tools (all of them), and right now 99% of the money I have is going to my next album release... BUT!

I just ordered jhaible's Living VCO to add to the pile (which isn't much: five 292c clone boards, and finish this dual 281 clone I picked up from Peake). hyper

these are free smile

i have a friend who works at a printing place who can make a few cheeky prints from time to time
she can only do A4 though so it means i have to do this panel in 2 segements

here is what i finished today. my new sequential switch. it switches all signals from -15V to +15V, providing switchable 2/3/4 steps, voltage controlled and manual clock and reset.
i plan to normall the O/I socket to +5V, so that it could even work as uneven divider (3 step mode). this module is the very best friend of the divider module i built earlier this year (see below).

oh duuuude!!! SlayerBadger!

Can you post some more info about these?!?
[.dust]
wetterberg wrote:

Here are the planned specs of the seqencer:

    - 16 Steps
    - 16th Clock in for Slave-Mode
    - Internal Clock Generator with 16th Clock Output

    1 Track with
    - 16 Pots for Step CV
    - 16 SPDT Centre off switches
    - 16 LEDs for activity monitoring

    The Switches are for "Trigger-Off-Gate" per Step

    Global Controls
    - 1 Pot for Step 1,3,5,7,... Gate Length
    - 1 Pot for Step 2,4,6,8,... Gate Length
    - 1 Pot for Internal Clock Speed
    - Run-Mode Dial: Off, Forward, Reverse, Alternate, Random Forward/Reverse, Random Steps
    - I will use a pot for Run Mode Selection, because encoded rotary switches are f**king expensive.

    Outputs
    - gated CV from Steps
    - Trigger
    - Gate
    - Inverse Trigger (If you Set for steps 1-4 i.e. 1-0-0-1, this output will give 0-1-1-0)
    - Inverse Gate

    It will use the Arduino Mega Board.


Atm the software is almost done. Now i have to build the hardware. I will start this end of july, after my summer holiday.

There are options for 2 more Gate Pots for 1,5,... + 2,6,... + 3,7,... + 4,8,... Gate Control. and an additional random gate and random trigger outputs. But I am trying to fit it on 32TE. On 40TE i could include this pots and the outputs.

It is a quite simple sequencer - nothing to be compared to a MAQ or Oberkorn - but i want to build a sequencer that does not waste nearly a complete row in the rack.

I will build v1.0 for me and present it, hope for some suggestions to improve it, build a v2.0, present it and if some people are interested in, i will build maybe up to ten of them.

got my dual wogglebug wired
i just need to chain the power and then do testing on the second pcb
not sure how im going to mount the pcbs yet tho
still need to etch my dual disturb / ring mod pcb and attach too

erhh more wiring
im starting to see the upside of pcb mount pots and jacks





it seems like such a good idea to have lots of dual and quad modules still i started having to wire them up haha

Luka, that dual bug looks fantastic - now I want to build one like it. Woggle Bug!

Edit - Pristak, it looks like we were both posting at the same time. I love the look of that VCS! So much so that I copied it. Actually I've got a second one sitting here, almost finished except for attaching the wires to the jacks, etc.

Just finished this -

im actually about to re-make my panel as this one is frac and my suitcase is euro. so if anyone wants it let me know. i will also have a resonator+panner panel up for grabs.

got my boxotrix happening
well not there yet but time to start posting some pics




and once again here is the insides
dont we all love seeing the back and insides
makes all the hours spent wiring kinda worth it i think



it is about 2/3 done now
still waiting on the final design for the panel so i can order the vinyl overlay
also need to still order some parts for the compressor
and im going to make a cool stand for it.. just some ornate legs/frame so i can pivot the box. i would like to find some thin iron but i think ill just go steel and get my housemate to cut out a cool rought iron esq pattern

cant wait to make some loud distorted noise smile
Roycie Roller
Geez Luke you're churning them out. I like the compactness of this one.

@sduck- that's a beautifully realized panel design! The coloured text looks great.
DGTom
Noice wiring Luka!

Not nearly as nice, but I finished up my CGS simple Wavefolders. Was gonna do bells n whistles but decided that a Quad in a single width Frac module is just stupid enough to work;



You need to run a mixer in front of each one... or do you!? Awesome for CV bending as well screaming goo yo
sduck
Here's another Blacet>MOTM repaneling. This one worked a bit better. The naive pots won't fit onto a 3mm panel, which is the standard thickness of everything else I have, so I countersunk 1.5mm holes behind the knobs, and it fit perfectly.

Well done! That's a good iron- did you get the one with variable temperature? It's a good idea to experiment first with cheap projects or even kits (eg. Velleman's kits)-

http://www.vellemanusa.com/us/enu/product/list/?id=342508

Basically anything cheap that you don't mind destroying for soldering practise. Soldering's like riding a bike- the first couple of times you suck at it, then you get it right.

I use about 0.5mm or 0.6mm solder for most pcb work. 1mm is good for pot wiring & other panel controls, but too thick for IC sockets, etc.
60/40 (60% tin/ 40% lead) is a good ratio for SDIY work.

Many parts such as IC's & capacitors can be damaged by excessive heat from holding the iron too long on the part. Resistors fare better.

There are a couple of 'How to Solder' videos on youtube which are very helpful when starting out, eg.-

SepticUnderground
wow Sduck, your DIY panels are really great, i like that deep-laying colered lettering, gives it a fruitylook somehow in the black panel smile

Rasta-nana me likes.... that J H stuff is really great, I wish I could do that kindof stuff myself, but when I remember how I made those revellclub™ modelplanes when I was a kid....no wheels standard and no antennas or propellors, window canopé alwys completly smutthered with glue haha...

And all the other guys aswell ofc...but this is very continous in design with that different colorlettering for seperate modules etc..very nice.

ive got my euro suitcase coming together




and im starting to lazertran all my 5U modules (FINALLY!!)

i should get my shipment of 400 david knobs next week
and ill order all my bananas and 40 pomona cables then also ($$$ :S)

SepticUnderground - thanks so much! Yes, the JH stuff was almost beyond me, but I managed to pull it off with a lot of help along the way. The FS1a isn't completely debugged yet in fact.

davis clones just arrived
johnson and pomona order next week woot

im about to lazertran my klee
im pretty scared about having to use 3 sheets of lazertran

:S




that there is (from left to right)

quad function generator
dual state variable vactrol filter (buchla 291 w. lots of mods)
mankato
twin cgs vco with all options
there is also a super controller hidden behind me too

i might have to acetone the cgs vco plate
i cant for the life of me wash the burnt bits off
my wavemult and low pass gates also kinda failed during lazertran

so lots to do woop

I wish! Tell that to the pile of nearly 1000 1/4"ers ready to go very frustrating Flight's cheap jacks and the prospect of stacking cables are killing me Rage!

Makes me wonder why I chose 1/4" jacks anyway. Oh yeah, because I thought I would actually use the thing with my other 1/4" gear and the time I tried an ARP 2600 I was put off by the "wimpy" looking cables hanging from it.

Cool! Just curious, how fast does it go in each of the ranges? Is there a single setting where it will go from fairly snappy(doesn't have to be the snappiest ever) to reasonably long(doesn't have to be coffee break long)? I'm trying to put 4(duals) of them one one panel and I need to eliminate some switches.

The programmer isn't that hard to build. You build all the boards separate, and then you wire them together. The biggest problem is the wiring of the G, H and J buss, but with some reading you'll sort that out.

Yes, there's a total of 4 281 boards in there.

I'll finish the 281:s this weekend.

yup the medium setting of the time switch is probably the one you want!
this is the setting i seem to use the most.

i can see the number of switches becoming a problem with that many units woah

Well, just about all the parts are here, I'm gonna make me a LoPass Gate, Foniks Attenuverting Mixer and then hopefully after that a MFOS sequencer & quantizer.

I've just finished my first BananaFrac panel, for Ken Stone's pulse sequencer, took me a while to get the paint and lettering right, but I'm quite pleased with the results...

Now on to the other 16 CGS seqs, 12 other CGS boards, 16 Fonik boards, 40 Haible boards.......

Is there any way to stop this? confused

I guess I was kind of influenced with old machinery/medical equipment, and stuff like analogue computers.

I found an old x-ray machine in a barn in France once, and it was this colour, it's stuck with me ever since.

Also Bugbrand and the banana crew were quite an influence, in terms of BananaFrac...

It's dry rub transfers (like Letraset). I found a guy who did vinyl lettering for a job at work, and when I went to see him, I saw all this stuff he was doing and thought I'd try it out. I'd heard about people doing it before, but never tried it. I had planned on etching, but never got round to it!

To be honest it's a bit of a PITA, they always go a little wonky, or the transfer will 'jiggle' as you rub it on, so some of the letters are off key, but I think it looks okay as it is so small (6 point). It helps that the Banana sockets are colour coded, so I never need to write "Audio in" as that would just be a yellow socket, thereby cutting down on transfers...

If you are thinking about it as a something to try, it may be worth noting that the panel surface is important, the transfers don't seem to like gloss paint for example...

I've got white inputs and red outputs, and the legend (I kinda like little writing!) goes IN - OFFSET - OUT - MIX. I've also got both AC and DC outputs. An amazingly useful module Fonik! (I guess that's why I've got 5!) So I can patch in an offset on channel 1, invert it and send it out, mix audio on 2 and 3 through the AC output, patch the offset from channel 4 into another module....etc... I can't begin to describe how useful this is, I tended to concentrate on building "exciting" modules before but now I see how this opens the synth up... Basically each one ends up in the centre of a patch - looking like a bowl of spaghetti!

In terms of wiring up, I just changed each switched socket to two Bananas, eg input/offset, its cheaper than using a switch, and you can use more options at the same time, I find it easier in this sense to read off the schematic, as I can see exactly where to tap in and out of the circuit. I suppose the only downside of so many sockets if the mess of wires behind the panel!

i totaly agree. the attenuverting mixer is a module you love on 2nd sight. it does not alter the sound by itself dramatically, but it gives you a lot of control over the control voltages. glad you like it.

To steal a page from the tale of Milo of Kroton:

"The story of how neandrewthal got his strength has been told for over 2,000 years. Briefly, his self built him a synthesizer for his self to play. One day, wetterberg asked him, 'How big is your synthesizer today?' neandrewthal ran inside, picked up the synthesizer and carried it outside to show wetterberg. Each day, wetterberg asked him 'How big is your synthesizer today?' and each day neadrewthal ran inside, picked up the synthesizer and carried it to wetterberg. This went on for a number of years. As the synthesizer grew, so did neandrewthal's strength."

Seriously, though, as long as I can have a clear pat to where I'm lifting it so I don't have to lean over and I remove the back cover so I have an edge to grab it shouldn't be too bad. I can pick up 300 pounds off the floor and lift 110 above my head in my toothpick state since I started lifting a few months ago, so an awkward synthesizer should be no problem after I've put another 60 pounds of meat on my frame.

do you have schematics?
i can only find schematics for the 295

I've seen a 296 in parts. And it would be a hell to clone.
It contains like 10 trimmers for each filter board. And there's 8 boards. It's not like you guess the settings of 80 trimmers. And it it would be pretty worthless to build if you can't callibrate it. Then there's VCAs and stuff in it that's practicly impossible to get today. - Which is why I think we don't see a 296e around..

I think the best to do is to design a new one inspired by the 296. You need like 16 voltage controlled bandpass filters and 16 envelope followers - and then you're good to go!

I'd love to have one! And if you have 2 you have an awesome vocoder smile

I've finished a layout, which I'm still testing, for the Envelope Follower/gate detector in 230 Triple Envelope Follower. It's a tiny layout and would probably make a good starting point for the 16 Envelope Followers in the 296. If the Gate Detector is not used, the layout would be even smaller (half the size).

I'm also working on a 295 clone. These filters are not voltage controlled, but they're probably similar to the 296 filters otherwise.

Do you have some schematics for the 296? I'm curious to know how voltage control is achieved? Vactrols?

There's a lot about the 296 that I don't understand though. I wish these schematics were available somewhere.

Here's my update as of August 31st 2009

I've been shamefully unproductive and unimaginative this year compared to the rest of you awesome folks! oops we're not worthy


Stuff I've got to build/buy for cabinet #1:
Add mute switches to Oakley MultiMix
--- on one large 2U 19" panel -----------
MFOS 16 Step Sequencer (I've started the panel design)
---------------------------------------------
Back light cabinet hmmm.....


Stuff I've got to build/buy for cabinet #2:
Tellun Neural Agonizer reverb (need to get started on dis somebitch!)
Add Tellun board to one MOTM-800 EG - have board
Add Tellun board to third MOTM-800 EG - haven't ordered yet
Add Tellun board to forth MOTM-800 EG - haven't ordered yet
--- on one large 1U 19" panel -----------
This is now going to be a front side interface for a Roland M-120 mixer that is going in the rack. (it is 1U too) There is also a small switch configurable mutiples section. The small holes in the Input and Effect sections are for mute switches. I've designed and ordered the panel.

---------------------------------------------
Back light cabinet hmmm.....


Stuff I've got to build/buy for cabinet #3
backing panels - haven't ordered yet
Replace DotCom QPS2 with large DIY PS like what is in cabinets 1 and 2 - Power supply - have most parts for it


Stuff I've got to build/buy for cabinet #4
Case back panels - - haven't ordered yet
Power supply - have most parts[/quote]

Nice logo, JLR! 8_)
2012
o yes thats a real cool logo!
JohnLRice
Heh, Thanks for the logo praise! 8_) Only took me 51 years to come up with that! lol

I am pretty pleased if I do say so myself though. It's simple and looks the same upside down etc. I'll probably start using on everything. I want to make a short (maybe 5 seconds) animated version to attach to my videos. It should start out very small spinning very fast then slows down as it gets larger and then some sort of lighting pulse when it finally stops.

I actually ordered a third panel when I ordered the other two I mentioned. It just has the logo on it and will be for the back of the rack. If I like it I'll probably get one for the back of all the racks I intend to use live. Not that most people will ever see the back of the rig but . . . . if someone does I want it to look a little "special". thumbs up

Now, if only I could get it working right lol I`m pretty sure it`s wonky, but I have to hit the books and figure out how everything is supposed to work before I can say exactly what`s wrong.

wetterberg, the ground bus wire was some old stranded pre-bonded(love that stuff)cable I pulled from a computer or something. I just stripped all the insulation off it, except where the analog and digital grounds cross each other.
sduck
Wow, that looks great! I've been tempted by this design, and already have another set of boards, but having built one klee already I think I need some breathing time first.

Love the 2 kinds of knobs - they compliment each other nicely.

Are you sure it's not working right? I was convinced that mine was not working right, as many have also upon first completing it. If you read that huge thread on electro-music.com you'll find my worries and those of several others. It definitely takes some getting used to - no matter how much you read the docs it'll still work differently than you'd expect.

One thing I can see that'll make it work better - you need a green load switch. It has to be green. Any other color won't work as well.

Haha, it`s so true. For one thing, I thought bus 3 was busted but it`s just the LED. Easy fix. Then I was concerned that I couldn`t get bus 2 to fire while another one was on. When I realized that gate 2 is derived from putting 1 and 3 through a NOR gate it was a d'oh! moment.

Now I know this isn`t supposed to happen: When ``invert B`` is off, pattern LED 16 is always half lit, and by the time the bit gets around to fully lighting it up, the sequence freezes until you hit the load button again. Considering the recalcitrant LED is only one resistor away from the switch that sends it haywire, I shouldn`t have to look too far for the problem.

Now, that brings me to my last ``problem``. When ``invert b`` is on and I try to make a traditional 1 bit sequence, the stages that turn on remain on until the 16 steps are done, then the invert b forces them to turn off again in the same order. Is it supposed to be like this? It doesn`t seem like desirable operation to me, but from my limited understanding of the schematic, it makes sense. When you load up a pattern where stage 16 is not turned on initially, it will invert and feed back into stage 1 and so on until every stage is on, eventually. Is there supposed to be some kind of mechanism that prevents this from happening until the first bit reaches the 16th stage?

if i understand you correct, it works as it should. it looks odd at the first glance, especially if you run it with only one active bit. but try it with 6, 7 or more bits active and the range switch set to a low value, and you will see how you get an interesting 32 step sequence now.

Yes, that sounds like something's funky - hopefully it's just a wire or led problem. I had one led that just needed jiggling or resoldering to get everything working right. You should definitely post in the E-M.com klee forum - Scott is great about troubleshooting.

That's how it's supposed to work. It seems a bit odd with only 1 or 2 stages active, but when you have a bunch active it makes more sense.

So, here is documented proof that it is now cleanand I have no excuse to not get power supplies, modules and patch cables built, repairs done and stuff modifed/fiddled about with! applause



Jeez John, that's just sick. You know you can get treatment for this, right? That solder dispenser is so, so... what's the word? Twee? Although I see you don't have a holder for your heat gun, so there's hope yet...

I should post a pic of my workbench just to even things out here, except it's spread out over 3 areas, like most normal people do it. I think a picture of my garage workbench would make your computer explode.

Finally getting some panels I'm happy with ambulance

This is a dual Fonik LPG. Instead of switchable modes I opted to hardwire the top as Low Pass & the bottom as VCA with the switch to cascade the top thru the bottom. No resonance or anything fancy, I have 4 TW292c boards for all that;



Tomorrow I take it apart again to start messing with artwork grin

Luka & I did a trade of surplus to requirements stuff & I scored his mad Frac Dual Wogglebug;



I just need to finish wiring up the disturb inputs & work out how I'm gonna mount all the bits n bobs behind the panel hmmm.....

Nice work DGTom, I made my Woggle panels, and forgot the Disturb circuit d'oh! Looks like I'm making more of those! Also What is Foniks LPG? Is it the Buchlaesque module from his site? Did you etch your own board for that?

And your Klee looks pretty cool Neandrewthal, I made the mistake of making two at the same time; putting one behind a temporary mdf panel which looks shit (I wanted to test how it would get laid out) and leaving one in a rats nest of wire and cat hair... waah

I used all the connectors, I can only imagine how you wired that up without them, but no doubt you also catch flies with chopsticks too!

Finished the Neural Agonizer!



It's behind a Bridechamber panel that I bought ages ago - since getting it I saw neandrewthal's panel and really wanted to go that route or something similar, but in the end did it the cheapo way.



I still haven't bought the reverb tanks for it, but now I can't put it off any longer, so I'll get them asap.

I had interesting results using a diode (as a half-wave rectifier) on pins 11 & 12 of one 4046 (i think the one on the left of the pcb). I wired a jack through a 1k (or 10k, can't remember) resistor & a 100k pot & onto the diode.
The pot was like a mix between the dry signal & a modulating mix of the dry & input signal at the diode.
I'm fairly sure the disturb circuit is on pin 11 or 12 of the 4046 as well, but designed to protect the 4046 from negative voltages.
Also, if you're in the yahoo wiardgroup, check out Doc Mabuse's add-ons & modifications for the woggle...very interesting stuff.

Another excellent build sduck, but just to be an ass, my panel cost me $10 goatse.cx

If you're judging against schaeffer then you probably saved 75%

interesting hmmm..... It might be usefull to have a wogglebug mod thread at some stage. My plan was basically to use the disturb cct. from Richard Brewsters adaptation - this is more or less a buffer/rectifier/crossfader yes?, but implemented in a slightly wierd way to 'synchronize' disturbation (not a reall word) across both bugs.

I have a 3rd board I'd like to mess with alot more as well, spurred on by the idea that you can connect any 2 points in the cct with a 10K resistor without causing any harm grin
Scott Stites
Not to derail the direction of this thread, but did you get the Invert B problem sussed yet, Neandrewthal?

Fonik's right - Invert B simply flips the bits coming out of the B register; I generally use some well spaced bits for full 16X1 Invert B sequencing; the pattern will be less see-saw. I use Invert B most often, I think, in 8X2 mode, because Register B will produce a sixteen step pattern while register A is producing an eight bit pattern.

Here's an example of 16X1 Invert B. Two outputs (IIRC A+B and B) are driving two voices through two different thirty two step patterns. Towards the end I bit shuffle a bit using 16X1, 8X2, Gate Bus 1 Reset and flipping Invert B on and off. Never adjusted the range on this one - the patterns handle the variation fine. It was all recorded in one take through my Dim C/TZF. It's one of my favorites.
sduck
Finally got the last LPG built. Here's the 1u version. Now I have 4 of them behind 3 panels.

Would the wiring have been easier if the pcbs had been arranged differently? Facing each other? Or rearranged so that you wouldn't have to go around the stooge panel with cabling?

if i got really long stand offs then perhaps
but they are proportionately more expensive than wire where i get them from

then again trying to debug and tune stacked pcbs is a mega annoying so i'm happy with this build

design the panels in illustrator
print lazertran on my lazertran with my lazer printer
bake lazertran onto plates
drill holes
cut up some pcb mounting plates and make some brackets from some alu sheet
then populate with panel componetns

JohnLRice
I got my MFOS 16 step sequencer panel in today and I took the time to mount all the controls, here are a few quick crappy shots. I'll have this in my rack at the PNW Synth Gathering but I'm pretty possitive it's progress won't be beyond what's shown here by then (too much to do . . . Dead Banana )







In my build I'm using lighted pushbuttons instead of speperate LEDs and switches to save space (the red translucent 'Line 1' indicators will be replaced with white translucent 1 through 16 indicators once I get around to ordering or making them). When one of the switches is depressed, it will glow at half brightness when that step isn't active and full brightness when it is. When not depressed it will be either off when not active or at half (or full???) brightness when the step is active. (this is all in theory, haven't even tested if it will work or not! MY ASS IS BLEEDING )






I'm also using multi turn pots instead of seperate course and fine pots. I like the way the standard knobs look on it but if later I find I really want to know where each setting is I'll put on counting dials instead.



I'll be mounting the circuit boards on a rack shelf behind the panel and I'll probably need to put a peice or two of thin angled stainless steel etc befind the controls to keep the panel from flexing.

Thank you for the kind words Mr. Wetterberg sir! we're not worthy

I posted a lot of this info in another couple threads but . . . ! Mr. Green


The switches were C H E A P!!!! Got them from surplus sellers on Ebay.

The square ones I got for $1.50 each from these guys (they are excellent sellers with good comminications and fast shipping):
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270174712474

The round ones I got for $3 each from these guys. They have average to slow shipping, the LED's are missing from the switches, they are NOT DPDT and they will NOT answer emails! Still, the price is not too bad compared to retail:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=380008646159

There are a couple other sellers on Ebay right now that have the square ones. Do a search on "NKK LED"

You can get alternative colored caps for the NKK switches from Mouser etc.


I got the Spectrol 100K 10-turn pots from Tedss for only $5 each:
http://www.tedss.com/item.asp?id=2022001292

I also got the Switchcraft jacks from Tedss.

It's taken about a year of toiling over a soldering iron, but I have finally finished my first row of modules! In lieu of decent photographs I have uploaded a video from my iPhone - the picture quality isn't great but the audio is pretty decent quality.



The modules from left to right are:

ARP Odyssey MKIII dual VCO
YuSynth ADSR (although it's not being used in this patch)
YuSynth Minimoog LPF
Buchla 208 Random Voltage Generator
MFOS Buffered Multiple
CGS Utility LFO - this is in a temporary panel made from perspex.

Hello Everyone!

Is it too late to get in on the fun here?

I don't really do projects from year to year, I start new projects in September and have to be finished by the end of May. In the summertime I don't have time to build anything.

Last winter I built a banjo interface for my synth. (I don't play keyboard) It was completed last spring, details are here:

http://www.electronicpeasant.com/projects/ptv/ptv.html

This winter I'm building my second SynthCase* project, I'm hoping to have it completed by the end of 2009, but it may spill over into 2010 a bit.

http://www.electronicpeasant.com/projects/syncase2/syncase2.html

I don't really build modulars so much as "multi-modulars", lots of non-interchangeable modules in each case. I like to be different!

Take care,
Doug


*Not to be confused with the Synthcase.com modular case manufacturer.
Luka

Welcome Electronic Peasant!

I think the whole "2009" thing is pretty loose, much like everything else here-abouts hihi I know I won't be finished much of my projects until 2012... by which time it'll all be too little too late I guess lol

Looking good! Case #1 is awsome & it looks like #2 is well on the way. Wish I could decide / stick with a layout / module choice; modules are the perfect way for the easily distracted like me to flip-flop from oe thing to the next oops

I really like the stand you used on the lid of case #1. Very nice thumbs up

Doug, welcome! Your work is really inspirational to many diyers, and WOW, syncase2 is MASSIVE! I don't think I've ever seen the JH stuff done up quite like this - and the interpolating scanner in a portable case? That's just crazy, hehe. Crazy good!

I finished my Buchla 291. It works! I still need to label it, but I wanted to finalize the feature set first. It's a dual filter, each with one attenuated input, one center frequency cv input with bipolar attenuator, one bandwidth cv input with bipolar attenuator, attenuated audio FM input, resonance, BP, LP and HP outputs and one switched output. I'll soon have a final image and some sounds!

Great stuff Doug,

Yours was one of the sites that got me started in this - I really like your recycling ethics, I especially loved the bead knobs you made!

I just thought I'd post up the years building as it is coming to a close...

Though I'm hoping to get quite a bit more done leading up to Christmas and over the holidays - I cut four more cases and just need to screw them together and paint them so I'll actually - I think for the first time EVER - have more rack space than modules!

Thanks for your comments guys, but it is seeing all the work you do that spurred me on...

@ DGTom - Yes, luckily we have a fully equipped wood workshop at work, with extraction and air-filtering, though TBH my lungs are probably already fucked from years of self-inflicted abuse, and dodgy working environments!

@neandrewthal - the 8 way switches and counters are parts of a mega sequencer I built, but remade as part of this system, the idea is to have pulses going eventually to a trigger-midi converter controlling a sampler or two, the switches enable the destination to be changed on the fly, kinda like programming an 808 - well, sort of! But they're also useful for other things, like choosing divided pulses going into a sequencer, playing melodies etc...

.......... to a trigger-midi converter controlling a sampler or two,

thats what i like to do myself. controlling a sampler from the modular.
Which CV to midi interface do you thought to use ?

I had mails with doepfer asking for USB64 and MTC64(or something).
Those both seem to be to slow.
one must expect over 10mS delay, maybe way more.
the bad producer
Hi Funky40,

I used the CTM64, and made little circuit boards with CD4066 electronic switches to trip the contacts when they receive a pulse, I did it all on strip board ages ago, so it is a bit of a mess:



Never noticed any delay, and I've used it to switch samples at audio rate (sort of like a wavetable osc - which was the point I suppose)

The only down side is that samples are always full volume - or rather play at a fixed volume which you have set.... But this can be overcome later in the signal path...

I find them very useful, and I've built up 8 or so each one with a dedicated hardware sampler...

Thanks Funky40...

I was thinking that as I've finally got round to etching boards for myself, that I'd re-make the switch boards so that they were not on stripboard, which should make the module less of a nightmare to wire up...

I've also got some plans for adding velocity - using banks of simple VCA's - but these will indeed wait until I've cleared my backlog somewhat!

@Doug, really impressive to see your case coming together so quickly! It's inspired me to make a little synth out of an old typewriter case I found with JH's Living VCO as a main oscillator, so thank you!

great work. looks fantastic! you left a lot of room for operating your intrument, i like that. and i bet this contributes to the look a lot! i tend to cram full my front panels with sockets and knobs. you set an example how to do it better, IMHO.

neandrewthal and consumed really show us what the fuck is up. Both elegant solution, and yes, it's upsidedown world: The eurorack is spacious and strict, and the 5U is dense and sprightly!

I agree!
excellent work by both consumed and neandrewthal.

Man I really failed my personal 2009 DIY Challenge.

What I did:

Convert my Frac stuff to banana jacks
Semi-DIY Little Boy Blue (case, wiring)

What I didn't do:

Even look at the pile of PCBs that are sitting here.
Order parts beyond two 292c clones, and a ChaQuO kit.
Anything else.

Um, 2010 will be different! screaming goo yo

Thanks guys Hug

Yup, it's dense, but when I looked at the size of my backlog, I decided my priority is to have everything within arms reach rather than take a hike to make each patch connection wink

I've done it! I have actually managed to complete my latest synth project before the end of the year.

Here is a picture of the wiring in the second half:



Today I finished wiring up and testing the JH Chorus section, then I buttoned the whole thing up and started playing. This project is a huge addition to my modular setup, with lots of great new modules to experiment with. Time to make some music! Rockin' Banana!



Take care,
Doug

The Peasant - that's great! thumbs up Can you tell me how deep the base and lid of your case? Looks like a tight fit for everything! woah
wetterberg
just awesome. Would love to hear this!

I don't know which side of the panel is sexier hmmm.....

yup, having everything within armreach is very important, but having FULL (Finger)access to knobs is even more important.
I found out on my patchings that it is often the unexpected Knobs that gives the groove while twiddle, so i begun to give every knob some space help


what you loose on functionality because of less Fingeraccess you cannot get back. There is NO WAY. granted !
all my best grooves and recordings where mainly a result of jamming the knobs, sometimes very excessivly.

Thanks! It was a very tight fit, and I'd have to measure it to be sure, but I had about five inches total space to fit in both the top and bottom panels and electronics. I used low profile capacitors on the circuit boards and was careful about parts positioning, so it all managed to fit in just fine. Clearance under each panel was just over an inch, and when the case is closed the knobs on the two panels just about touch each other.

Take care,
Doug

Some of these pics were posted over at electro-music already; Figured I'd post them here also before the end of of '09.

Nice stuff! Do you know if Mark's 258 is designed for use in a Buchla system?
Could you just set the v/oct trimmer to 1.2v/oct & it would work?

Yeah, the whole thing is a clone. 281s and 292s from electro-music buys, verbos 258s (which I haven't gotten working yet, but others have) and 291s, and romeo's 266. I have a few other's planned out, a 295, 259, and hopefully a touch controller eventually. I have some 100 clones too, but I probably won't use them.

The faceplates and case I've been working on for a very long time, trying to get them just right based on pictures. The PS and distro is designed after the current Buchla switching PS. So, it should be compatible with 200 and 200e modules, if I'm ever able to afford them.

His DIY version is designed for v/oct. I don't know for sure, but I don't think it can be trimmed to standard Buchla. For me, v/oct is more practical anyway.

many thanks for that! i have taken your DIY work and used it as inspiration to DIY my own euro. on the contrary to your comment, i think that your designs are very well spaced out. regarding spacing on the oakley little lfos--i would probably have put those pots closer except the pcb/pots/pot brackets are laid out to MOTM grid spacing (1.625") so i just went with it. allowing empty space in a panel design is a really difficult thing to do.
