Good vibrations.

Learning electronics. This was the first kind of circuit I ever put together. Decided to recreate it the astable multivibrator. Discrete parts can be a bonus sometimes.

Schematic:





Parts used:

2 - leds (different colors adds more mystique)
2 - 330 ohm resistors
2 - 10k ohm resistors
2 - 2n2222 transistors (npn)
2 - 100uf  50v Electrolytic capacitors
1 - 3 volt battery

Blinks fairly fast. You can exhange parts to see what it can do. The actual circuit:

 



What should happen: (different circuit, but essentially the same still using npn transistors.)
