Muff's Modules & More

I have nothing fancy, just a MFOS Dual VCA with a frontpanel from Bridechamber (the CV2 and audio inputs are normalled):

edit:

The first day I was able to finish two modules. Here is a 4ms SCM built from a kit:

Thanks everyone.

The pushbuttons are from Mouser: 10PA005 for the red ones. They also come in black and white.
If you use them in the prog/ seq be aware they interfere somewhat with one of the buss wires that run thru all the boards. Some teflon tubing will keep it from shorting.

Finally! Definitely learned a few things on this guy. Such as, don't give yourself such a tight space to work in. Don't make mounting a PCB harder than it needs to be. Lastly, test everything before you mount it! Luckily I figured out that last one before I assembled the second half!

brian!

all working?

re PCB mounting: the core/waveshaper PCBs could be mounted back on back, however, i did not do it on mine. i mounted them in parallel to the frontpanel, showing all trimmers...

Ok, here's one that wasn't in my backlog but I fixed Dude's version of this for him and then he sent me a pcb in thanks and I already had most of the parts on hand and the panel basically designed itself and before you know it there it is.

Another beautiful and cheap roof flashing bracket. This was also an experiment of sorts - I've been looking for a cheapo panel to try FPE's powdercoat process with, and this is it. It looks and feels really nice, and seems a lot more durable than the usual anodized panels. And it's REALLY black. I'm not sure it's worth the extra 15.50$ they tacked onto the price - that didn't show up in the design program.

So far this weekend,

YuSynth Pulse delay
cgs Sub Osc
YuSYnth Comparators

Feels quite good to have the sub osc assembled, its around 4 years ago I ordered that pcb! One of the first ones that I ordered from Ken. Back then I had my goal set on making a euro sized banana - didn't turn out that way.

Yesterday I had this one up and running,

Are you in a hurry? With the nice work and all...

Finally got around to doing the panel wiring on my CVP - had the PCB stuffed and ready to go for a month at least. Yay!

falafelbiels: Thanx, no hurry, have no deadline, but I figure since it feels like I wait on parts most of the time, I better finish things up when possible.

Not the most exciting DIY, but still w00t

nice! how many Amp?

LoFi Junglist · Posted: Mon Jun 11, 2012 1:50 am Post subject:

The regulators (LM2575 & 7805) are all rated at 1 amp, but the Polycaps limit +/- 12v to 500mA each and the 5v rail is limited to 200mA. (I'm only doing the Regulation & Soak tests at 450mA/150mA)

These boards will end up in two ABS Camera cases for some portable fun.

Where are those PSU boards from? They look great, do they run off a AC / AC adaptor?

LoFi Junglist · Posted: Mon Jun 11, 2012 2:37 am Post subject:

They run off 9-15v DC.

I'm putting together Kits atm, but the documentation is taking ages. There will be something in th DIY forums next week thumbs up

Maybe a yawner for some here but it was a pretty difficult logic puzzle for me. Of course it still has bugs but that is going to be fun to tidy up.

Dual LFO / Analog Shift Register (x2) in a 3 space MOTM 5U.

Ken Stone's Utility LFO is the dual LFO here. Nice module in itself. The ASR's use the square out from each channel of the LFO for their master clocks until a break-in jack for external clock.

There are some goodies involved here. Mute switches for each register stage and a Loop and Series function. The LFO has a Hi/Lo speed range boost.

The Loop function has some problems. It submits the last register voltage over the first one right now. Hmm...

The Series works well. It forces the clock from A to B to keep timing across all six stages.

The logic puzzle was how to get both Loop and Series to work and all the variations of each on and off. Two 4PDT switches were used. Hopefully I can get it all perfected soon.

Here are a couple of videos. I'm unable to post pics to this thread right now but there are a couple of snapshots in the "demo" vid.

DEMO first...
