Cute circuit, but the 555 can be rather sensitive to temperature. Room
temperature, that is.

Can't complain about the price though!

I thought this: http://dx.com/p/digital-temperature-controller-66334 was
cheap. Well it is, but anyway. BTW those are quite good, they'll do heat &
cool (eg oven & fridge control) while most only do heating. They're also
76x76mm, not 48x48mm unfortunately.
