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.

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!
