Ethan ,Yes I concur about using it with non terminal cells, good point.
I don't think I have uploaded layout files yet. The layout has not changed since page 11 but I have altered some odd component values (resistors down from 1k to 330R in some places). So I have now uploaded the pcb design files for those who want to tinker with pcb etc.
The zip file contains the latest software/schematics and pcb design files.
