Which version are you going to build?

This is a rebuild. Back in January I went out and bought a nice big 2 metre tall, 80cm wide, 25 cm deep bookcase for £20 second hand from British Heart Foundation’s Furniture and Electrical shop. I wanted to build my synth in the bedroom so after taking a couple of photographs and measurements I dismantled it and took it up the stairs. It lay in bits until today. I took a couple of hard-won hours from my caring duties and assembled it.
The lower area is for patch cable storage, power supplies and the like. Then there are the five shelves it came with. The second one up is fixed but all the others are adjustable. Here’s an arrangement I arrived at without any further drilling, by using only the provided mounting holes and pegs. A5 panels can be mounted between 1 and 2, 3 and 4, and 4 and 5. At standard paper sizes there is room for 5 A5 panels on each shelf. With extra woodwork I could install more panels but I think 15 is enough for a beginner. Spaces 2-3 and 5-top can be used for standalone gear meanwhile. A Behringer Crave and an A5 greyboard blank are shown on shelf 2.

It’s the simple envelope generator:

I made a kassutronics kosmo version, which I will publish as soon as I have tested it

I was very surprised that I pulled it off. It took a lot of careful measurement and pencil lines.

another VCO with sync H&S, Fine tune, Fm, PW, PWM, 2 CV
but also the rotary switch for octave select
(the Sine wave is really too low, i come back to it later …

@d42kn355’s white 2 x VLPG looks great with my favorite NOS flat cylindrical yellow LEDs:

DIY Braids THT version update:
Finally got the firmware running!! Still no output, but getting closer! The wave comes out of the DAC, but is lost somewhere in the output opamp… I am soo happy that I did buy a oscilloscope now! otherwise I would have no clue if the bluepill is even working!
The Problem with the firmware was that first I had a bluepill with too little flash (they come with 64 and 128kb and with the new one I took quite some time to learn how to use the programmer and then I learned (after an hour of frustration) that I also need a bootloader!

through adversity or struggle to the modular ?

Forever amazed at the rate of your output - I’ve built about 6 modules in as many months whilst you seem to have a new module every day!

In fact I have been working on this case since March, but a lot of export problems, (the other case does rather in 2 months).
when I make a new case, I calculate the number of modules that I think I will achieve, I make them to fill it completely, and after when it’s finished I spend my time playing music and composing, until the next project case.
So I am not doing one module per day at the moment, my 3rd case is finally finished and now I install the modules one by one in it.
Unlike many people here who do modules little by little, I do a complet case.

I’ve been doing it by the case as well. Mostly waiting on components.

Good to hear. This is my plan for 3 cases. I may even look at a single board or panel design. Any tips on doubling or tripling a design on stripboard, panels and schematics? What circuits work well together? What are your inseparable combinations that might be useful as an imodular block?
( Sorry @Dud I’m asking all not just you)

Well, the classic one would be VCO, VCF, Envelope Generator, VCA.
