Cacophonator for Christmas

I wanted to give my brother a present for christmas, as he's always very good at finding gifts for others and I thought he was in need of a delicious little noise box for his new home. I find he has a good tactile connection with knobs and sensitive ears and he's usually good at petting my other toys.

So I thought I would support my friends at Dimsos, they're putting together DIY kits and throwing workshops in soldering and building of these simple little noise devices.
For my brother I picked the 'Cacophonator' (the term is a mix of cacophony, meaning harsh or dissonant sound, and oscillator) which is based on the 40106 hex schmitt trigger. The two larger knobs in the top are starve pots, for starving the synth of power which creates these bizzarre patterns and squeeks. The 6 smaller knobs are all controls for each oscillator on the chip.
I used diodes for mixing the output, so it has this ring modulation like sound to it.

Here's a video of my brother and I toying around with it:

I've also been recording some sounds from it directly from the output for your listening pleasure ;)

And here's the layout I used from Dimsos :
