Power supply build (Christmas Day 2018)

I started this about 8PM yesterday evening!
(After all festivities had ceased, mums back in their respective houses and baby in bed snoring)
Cracked a beer! First of the day.........
Jingle bells.

Image
Frequency central microbus. Parts picked!

Looks to be a pretty simple build 1N4004 first.
Then caps....then the problems!
Body diameter too large on 100uF caps. Had to float them above diodes.
Heat sink blades a bit too long.....had to modify these!
Fortunately it was a nice soft Ali....flush cut snips and a file later.......
Actually another rookie error? Maybe? 0.5kg of solder! That’s a big roll of solder. I think I accidentally got a lifetime supply on a roll!


Image

Not sure if the heat sinks should’ve had the mount hole moved so the sinks sit on the pcb? Oh well this is what I did! Second shot a test fit.
(Keratherm heat transfer paste used.)
Once I knew the problem appeared fixed it was time for some nosh. Had bacon cheesy chips which was new to me! Loved it. With some hot sauce and honey jack Daniels. Very nice.

Image
(Tea break 22:30)

After eating I finished the main circuit, still have headers and the leds/resistors per rail, then I’m done! Power test at 00:15.
Image

00:30, headers cut!
Image

01:40!
Done. Really happy! Still the last few bits (leds and resistors)
Image

(Note to self, I used a 16pin socket on the headers to hold things in place on the header strip, I noticed after the third header, the pins were starting to shift as the plastic warmed up. Re did these first few with socket, things are back in line!)
And it needs a shave!
That caused a problem at first power up. Despite checking, a short was apparent......nothing on the 5v rail. Bent a leg out of the way, power!
Lesson learnt. Trim before power up because I got lucky this time. Nothing went boom

2:03 this morning.

Image

Still needs a trim, think it should be fused between the pcb and jack socket.
12v ac wallwart 2000ma.
3mm leds used, just about fit the 5v led beside the erroneously huge cap body!
Overall a good start to my second year in modular!
On the 24th last December my first module arrived. Now I’m doing this!
And I love it.
I’ve had a lot of fun building these things, made a few good to me recordings. I know the sound quality is lame, and a few (gas gas gas) outboard items are needed, like a better recording facility! A multitrack something. And a big rack of flashy lights......That makes cds which work anywhere! Like my car.

But realistically some decent speakers would do. Ones without toddler tampered cones....or they are caves now........
:hmm:
Saying that we had a good few hours at the synth, she was happy as a lamb.
:party:

First major buy for the year.......
Guess it’s time for an update.

Weds.13th Feb.
Image

The mixer is awesome, I can’t believe it’s so cheap!
Another filter....I didn’t have High pass....
A mult 1x8 (can’t mount it yet but I have a plan!)

Built a bunch of diy stuff.......
The mult and lfo from frequency central are done.
Also built the spring reverb! The vactrol cross fader on this thing is erm....
A smile maker. :bananaguitar:

So now my synth looks like this.....
Image

F*** vca’s I NEED MORE RACK!

Why do I keep buying modules?

Anyway, enough with the stupid questions.

Yay.......eventually.

Image

Don’t know where it will go, or what I’ll remove!
But I know I neeeeeeed this module!


Also got a bunch of parts for the frequency central dual xvca.
So maybe I can have a little building splurge.

Nice 4x4 passive mult.

Post by Just another rookie » Sun Mar 17, 2019 1:20 am

Going back in time a little bit!
Frequency central multipoles.

Actually really like this module! Leds are really useful.
Fairly straightforward build. 4 resistors, 8 leds, 16 jacks and ground pin.
(Ground pin connects panel to pcb)
LEDs wired to show positive=green as this matches most other modules I have. Pretty cool! Actually had to look at the board and figure that out for sure. Simple enough yes, but a step beyond basic assembly.

Pic 1. 27th December 2018. (Resistors and jacks)
Pics 2. 31st December 2018. (LEDs and pin)
Pic 3. Finished module!

9u x 84hp
So my synth is overflowing.
I got a new pair of rails with the doepfer order.
Which I have filled (on paper).
I haven’t actually assembled it all yet!
But now my synth will look like this!
(I have two mutes modules so I’m already overflowing, AGAIN!)

Image

What size will it end up?
Who knows but there are things I would like to add to it.

The final pieces of this puzzle have arrived.
More clocking, another mutes and a mixer.
Oh yeah, and I got knurlied up!
(Run out of standoff’s......now is a good time I suppose)

Happy happy happy. Need a bigger case than the one I haven’t built yet but have the parts for......
Where will it end?
Who knows but I’m getting damn close to the mark!

Div kid mutes build 1
7th March 11:30-14:30

Image

Started off by tacking it all together so all boards lined up.
Finished off the board connects and power header.

Followed by leds, jacks and switches.
Vactrols last.
Had an issue with this one.
Quickly resolved!

Hurray. Bought another in the meantime.

Which I don’t yet have the vactrols for!
(I think that’s sort of leftfield funny.)

Learnt desoldering which I suppose is a good excercise!
Had a good chat about the issue and learnt a bit about the thought process of debugging which I think was a valuable lesson.

Enjoyed the build! Well thought out just like the ryo kit.
Very simple overall.

Really learnt that I must organise myself!
Desoldering wick, which was only a recent purchase was tucked away somewhere! That took way longer than anything else to find!

Still, I’ve got the vacs off and hopefully I’ll be able to get the new ones in and build a lead later this week! Hurray.

Need to build the third rail too.....
Another kludge coming up!

Time wizard!

Love this kit! Reminds me of collecting meat from the butcher.
Everything all nicely wrapped in a paper packet.

Talking of meat.....I could be eating a bacon sandwich!
Instead though, I’m building this.....quick before baby gets up!

06:43
Image

07:14 halfway through bag 1.
Nicely laid out! Blindly following instructions. One of the easier builds for sure!

After dinner.....
Very quickly soldered power header and jumper then jacks/pots and switches.

22:10
Leds and ICs

Image

Can’t test it until tomorrow evening!
Which means Monday is going to be long!
:bang:

I am excited by the prospect of this unit. It has been floating around in my head for a while. Then when I decided I really wanted it.

Out of stock!

Arghhhh end of play tomorrow will not be soon enough!

Ooh the Time Wizard, are you planning to use that to trigger percussion modules?

At the moment, I'm weighing up all my options for drum sequencing/triggering. I'm not keen on using a straight sequencer (e.g. kick on 1 and 5, snares on 3 and 7 style sequencing) as I've spent so long doing that in a DAW.

One option I'm looking at is combination of the Time Wizard, my PNW and probably a Doepfer A 186-1 OR combiner so let me know what you think of it!

Also good job on doing all the DIY. I thought I was going to do so much DIY when I started but having had somewhat of a bad experience, I'm a bit more hesitant now :mrgreen:

Hi Dave.

This is one of the best modules I own.
Hands down easy. I’ve only spent three hours with it yesterday but yes.

I pretty much got it to assist with the drum side of things but it isn’t limited to that. You could drive your whole system with it.
Half cycle triggers on two of the six clocks which could be used to gate a complex envelope (but I had to take that out to make this and the ryo fit)
Or just trigger the damn thing anyway!

Bye bye black vceg! That envelope alone did a lot for my percussion.
It has a pretty useful logic/cv expander.

My first patch with it for the six outs.
2 outs to doepfer a142-2
1 frequency central Adsr.
1 sync wave runner lfo. (Generates a further clock)

1 to mx61 mixer
1 to 2hp brst>mx61>bastl tea kick

Plus it needs driving from a clock source.

It’s changed my synth dramatically. Even though I have simple divisions available with the dreadbox divider, the klavis in lfo mode which is far from simple! It’s pretty loaded as an lfo! Check that module out!
It’s taken the load off other parts of my system that’s for sure!

I haven’t looked at Pamela’s but it is highly praised or suggested often round these parts! But I don’t understand it because I haven’t read the manual or watched a vid on it!

I’ve actually had a lot of fun with my (cheapest I could find!) sequencer!
All I don’t really like is the pull/push on the gates combined into the pot.
But it’s solid! Although there are loads of more exciting ways to get my vco to play a riff!

Cheers for the nod on the diy!
Don’t beat yourself up neither!
Once that thing fires up! You’ll be looking at the next in no time!

Oh awesome, that's good to hear! It sounds like it does a similar thing for you that the PNW does for me which makes me think maybe the Time Wizard wouldn't be the best fit for me as there'd be some overlap. The PNW can do 8 regular clocks with any amount of clock division you want, as well as being able to configure the slop, probability, phase and offset so it is really great for regular clocks (and sync'd LFOs too).

What I'm looking for now is the ability to get irregular triggers so rather than using division, it might go -|--|-|----|---|-|- (with | as a trigger) if that makes any sense. I was wondering if the logic options in the time wizard might be the answer there. Other options I've looked at would be MI Grids, Marbles or Noise Engineering Numeric Repetitor or Zularic Repetitor. They do feel a bit like they're "cheating" though haha whereas the time wizard, you'd need to do the division and logic calculation/experimentation yourself to get the desired patterns.

Anyway, you should post a sound demo at some point if you can, especially if you start making use of the logic options in the Time Wizard! I also didn't know there was a 2hp burst, that might be interesting for drum sequencing too! :hyper:

Just thinking out loud as it's something I want to try when I can do irregular clocks. A cool patch to try might be an irregular clock (using some of the logic options in the TW) into your sequencer clock then a /4 or /8 clock into the reset so that it is still in a repeating 4/4 pattern. Might add a whole new dimension to your sequencer.

You might want to think about adding a trigger sequencer like the Ladik S180 to your toolbox. I picked one up recently for exactly this.

Double kludge ultra bodge fuckery.
Yeah baby, I make ghetto look good!

Third rail extension Friday. Very quick 5 component case (including two rails!).
Now that’s bare bones.

Image
The top new section is fixed to the old part of the case, lo-tech double quick!

At least I don’t have floating modules held together with patch cables and pegs like some form of hallelujah mountains of pandora art appreciation society wreck anymore. That can only be a good thing as it would only be a matter of time before something shorted.

Still some re arranging but....part knurlied with all modules on display!
Now my synth looks a bit like this. (Saturday)
Image

I fear it is time to start seriously considering “THE” case.

I tried to do a vid showing just the time wizard in action but I got carried away. Until I ran out of patch leads.... :waah:

The only other module I use is divkid mutes.
A1 hats envelope A-142.2
A2 snare envelope A-142.2
A3 delay sync chronoblob (snare)

Clock B (both clocks fed from clk but multed to each input)
-means only clock A is affected by the multiply switch-

B4 tea kick trigger via mx61
(tea kick also triggers by brst and sequencer gate >mx61)
B5 gate black VCEG
B6 reset SQ8 sequencer (reset holds)

It’s hands on! But I like it.......

The great thing about DIY!

Post by Just another rookie » Fri May 24, 2019 12:14 am

A few times I realised I could do with another envelope.

Opened the box of bits, my last Christmas module.
21st April. 18:00-23:00. Including dinner breaks etc.

Image

Seems like there is a midweek pattern on build times.
The ampmix was about the same timeframe.

Frequency central system x Adsr. The 3rd in my system.
Didn’t take long to realise I still need a few more envelopes.

I may get another doepfer unit? The A-142.2
That leaves me with 3 kits to build!
The dual vca, the mutes and an attenuvertor

I’m hooked on diy. Help.

I think it was in the first batch of diy kits I bought.

Happy days. Built tested working mounted.

But that led to me stripping out every module and a rearrange which took the remainder of the afternoon.......

17:41!
Now my synth looks like this!

I mounted the dual vca panel just because......
Image

Not sure why some pics are wonky? I need more case.
There are a few things I still need.
Better sequencing.
More modulations....Adsr/lfo
More attenuation/offset type modules.
And the instruo lubadh......instead of the sample slicer!

Expanding up doesn’t last very long at all!
So I’m expanding across this time!
:hmm:

Yay for this instalment. I’m going to get to grips with smd it seems.

Whole load of envelopes, void modular dual Adsr times two, based on Roland 100m so should work like the frequency central ones which are highly regarded, but with blinky sliders!
(Suits me, the intellijel dual Adsr was on the list during planning before I spent a penny)

Plum audio buffers.....to umm, buffer stuff.

Tom Evans dual lpf. Love the blue panel......Heard it was good, sold.

And a bunch of busboards for the next evolution of synth expansion.

This should see me right :despair:
6x84hp.....will this be enough synth?

Yes I’m hooked!
Really need to stop buying things.
But;
Just need a few things to round out the drums.

I’ll start with this!

(Seeing double)
Image
Still not upside right.....oh well.
Nice compact percussion element! I need mooooorre!
This module makes good sounds, using the bastl n2 one of these and a propust I’m happy enough plus filtering!

So I got another propust and a lollipop compressor in the post too.....
Also some parts for the new blue filter, bits for the 2nd divkid module
Ummmm blank panels for the expansion! The next stage, I hope, will be enough!

NEEEEED MOOOOOORE RAAAAAAACK :deadbanana:

Already a rail and a bit into I case that isn’t built for modules I don’t have bits for, that is where I’m at. Plus my power supply is now grossly underrated.

Welcome to the world of synths!
Not ready to give up just yet but man, I’m so close to THE instrument!

Lubadh.
