Looks like you peed on a block of dry ice.

Don,
Very interesting, and an amazingly-simple circuit for what it does.
I'm trying to remember the color organ kit that I built. It was either from Eico or Lafayette Electronics. Either way, it was great fun for a kid just starting out in electronics.
Thanks for posting it.

WOW, blast from the past.
I built one of these back in the day.
Long gone now, but this help propel me into engineering.
Thanks Don

Wow, it uses PUT's .
Cheers
Come on, admit it. You peed on a block of dry ice.
Nope. That won't work by itself. I've tried it. You need some LSD, too.

ROFLMAO
Even older.. the old power-hungry unijunction transistors such as the
2N1671 (which Don used) and the 2N2646.PUTs (which are 4-layer thyristors) are still manufactured by ON and probably others as well!
