isopod

Ho-hum

The photosensitive plates I ordered (the cheapest I could find) are OMG thin. That's not much of a problem though -- it means I can cut the boards to size with scissors.
I etched the boards for the miniPWM and for the matrix driver, but unfortunately the layouts were mirrored. I need to check this before I start etching. :(

I did solder the PCB for the miniPWM -- I just put the IC socket on the copper side, the rest of the components don't care about being reversed (resistors, condensators) or could easily be reversed without any ill effects (78L05, elco's). And it worked!

Tomorrow I'll re-etch -- I still need to confirm the layout before I send it off.
