The Humanoise. My experimental noise device using LDRs and LEDs to alter synthesizer parameters

Deep in the body of a 'visible man' are LEDs that oscillate at a random rate whose range is chosen by the potentiometer tied to it (via a blue line). A middle color flashing LED works on regular intervals. Changing the ambient light changes the general frequency and moving and putting things in front of the flexTube LDRs can dramatically alter the sound. The LEDs are mounted on a Visible Man model just to make it interesting visually.
So far, the other knobs are:
PULSE - which throbs the oscillators
STARVE - Limits the voltage to the oscillators
TONE - slight tone and mixing of sounds
BKGND - a mini-FM-synth background
It was a fun project, and now on to the next experiment!

Now this is the reason why I wonder through every single YT corner!
This is huge great work!

[@zenSutherland]

Thanks so much! I love the mysteries YT has in dark corners! :D

[@CircuitBendingFool]

excellent

[@zenSutherland]

Thanx so much!

[@TOYBOXTHEATRE]

Man. This is incredible. we need to do another live show soon and use this!

[@zenSutherland]

Absolutely! It's always a fun time driving audiences crazy! :D

Great synth for a textured noise set. It bears the hell out of a Cacophonator. Is there a schematic available anywhere?

[@zenSutherland]

Thanks again, @stuartchapman5171 - it's built on basically the 40106 IC but the design and wiring kept changng over time so that it's gonna take a bit to suss out the details.

@zenSutherland they do evolve, I have a similar device housed in an old bit of medical control unit. Reverse avalanche, with ldrs, switchable caps, couldn't replicate it.
I have one with the chip you've used, it's in an office phone switching box, from the 60's, military gear. I've used one switch for power, another to make it self modulate, it has 4x4pole switches left, it'll grow in functionality.
