I’ve finally got around to take a picture of my modular. It’s still not filled up yet, but so far so nice and noisy.

It’s great to have control the 40106 chip with a joystick. Somewhere I found a joystick control from game controllers lying around in boxes and of course, a soap box.
Spuk

I think Spuk is a better name. At some settings it seems to spit out noises! Great! 4 Oscs Distortion Voltage starve
This is NObO on a breadboard for testing and designing the sounds I want.
There were some differences in sounds between breadboarding and on the pcb. The touch points became a little more predictable. But looking at the copper connections touching each other (bottom right) there must be some strange capacitance happening there. So to add more unpredictability modded is version 2.

I’ve also starting to build up my own modular with pcbs either bought or order and (in near future) to etching my own boards. (This is going to be fun!) I’m going to build a 4U system and (still deciding) going to banana plugs.
So we starting with, Thomas Henry XR 2206 VCO

The XR VCO is from Thomas Henry, with good help and documentation from birthofasynth.com and Bugbrand.
The functions are
It’s going to be sweet. I’m going make 8 Vcos! A huge jump from my current eurorack system.
Base on the minimal components used for the Op-amp LM386, I’ve build a octo amp running 9volts. Using the batteries might not be a very good idea, but this is the first off. All channels are functioning and it would be nice to test on a fresh battery to see how long it last outdoors!
