Went for a bike ride this evening, and it is was still hot outside.

Tried to use the Logic Analyzer to read the output from the serial bluetooth board, but I think I need to follow a tutorial since I seem to have forgotten how to use it.

I did test the tiny boost converters with some drained batteries, and they were all able to boost 0.7 V to ~3.3V
