Capacitors and Transistors and Chips, Oh My!

More Knitted Circuitry

This one is an astable multivibrator, kinda like the wee blinkie and includes two transistors and two capacitors. (Haven't put in the power lines, hence the test leads.)


This one uses a programmable ATtiny85 chip. Putting it in a chip socket means I can pop it out any time to reprogram it.  I didn't originally intend for it to look so much like a heart-- I was originally going for an argyle pattern. But I discovered that if you have something shaped like a triangle and you put a bunch of red lights on it, you end up with a heart. So... I gave it a heart beat.
