Now I need to figure out my charging and boost circuit.


It has been a long time, again. I have made a little progress. The battery charger works.

But I am experiencing a different problem now. I can not get the boost circuit to work. When ever I set it up and hook up the battery. It starts to smoke. I am using the basic circuit in the PDF. I do not know what I am doing wrong.


Mmm.... The things are known to be tricky to get to work efficiently (and often require a PCB to do so) but smoke usually means you have a short somewhere.
