What is max current on an AVR?
If an AVR can take max 40mA on each IO and max 200mA on VCC and Gnd pins.   This is simple when there only is one Gnd and Vcc, but for a chip with 3 Vcc and Gnd pins what is...

convert 0.2V to 3V
First I have no real need for this at the moment but had some thoughts about harvesting some power.   So if I have 1mA 0.2V from a temperature difference, (in general 24...
