Started building the charger circuit

A project log for explorad - input device

A small box with 5 buttons and (hopefully) a touch wheel. Serial output.

All parts are here, I can build the charger circuit.

The first step was to build the charger - without load sharing - on a breadboard. These are the parts I used:

An AVR is measuring both the battery voltage and the thermistor divider voltage and outputs them over USB serial, to be logged on my computer. The battery is currently charging and I'll post a plot of that later if it doesn't catch fire until then. To make sure that the battery temperature rises during charging, I've placed it in my computer's warm exhaust air.
