The Cost of doing Business... erm, Carelessness

After testing different ways of interfacing a uC with the Li-Ion charge control circuit, I accidentally put the over/discharge protection circuit out of commission when I connected the B- and the V- GND nets. Best I can tell is that the GTT8205S MOSFET got damaged and is no longer reliably connecting the battery to the rest of the circuit. Oh well. I already ordered a replacement.

Here's a circuit diagram for a test-version of the Energy Brain. I use an optocoupler to control the charging of the super-capacitor so that in later versions of the device an external uC on a separate power net can trigger a recharge of the capacitor.


Until a replacement for the fallen soldier arrives, I'll dink around with some other things. I've been reading up on artificial-neural-networks (ANNs) and that has been giving me some ideas, to say the least.
