Just an old hobbyist these days. I'm finishing up the written manual portion of a "breadboard helper" for playing with (learning) electronics. The current "helper" I am finishing up gives you instructions (and an explanation) for wiring up over a dozen transistor logic circuits with the aid of a small PCB + breadboard [1].
Inspired by Forrest Mims III, Don Lancaster and the "75 in 1" style electronic project kits my mom got for me for Christmas when I was a kid.
I hope to sell them and then probably never recoup my investment.
(I'll leave it as an exercise for someone clever to figure out what circuit is being depicted in the photo.)
Very cool! Where's the loopstick antenna, CdS cell, and meter, though? :)
