I have a Stochaos in my NLC Banana Jack Project. It’s such a fun module that I wanted one in Eurorack as well. Besides nine random pulse outputs, it has four stepped CV outputs and also noise and chaotic CV outs. The Eurorack panel has room for nine jacks vertically, one more than my banana jack panel can fit. So this one has an additional CV out and pulse output.

I’ve become proficient in soldering 0805 SMD components by hand. Stochaos has a packed main PCB.

I benefit from ordering inexpensive resistors and capacitors in quantities of at least ten. This reduces the size of parts orders for new module projects.

Stochaos has components on the jack PCB. These are the driver transistors for the outputs and LEDs. The module has 17 jacks, 8 LEDs and one toggle switch on the panel.
