Bacterial Incubator (Feb 11th, 2010)

Sounds devious, doesn't it? Have no fear, it's for growing yogurt making bacteria.

Powered by a 24W AC/DC supply, this little circuit board has heating elements built right in. The 110ohm power resistors draw almost two amps collectively.

The kit is from the good people at MTM Scientific.

Electronics is really quite easy when you're using premade PCB boards packaged with all the components and instructions. Just add soldering iron, air cleaner and PCB vise and you're all set.
