I don't have any heat sinks currently, so I can't make circuits that require them, like this one:
I read that aluminum is a good conductor of heat, so I'm wondering if it would be possible to construct a functional heat sink for transistor Q2 out of aluminum foil?
Also, must Q2 be a high-power transistor, or would a low-power one (like a 2N2222 or 2N3904) work?
