Right on the last day to enter the comp, the PCBs arrived from Oshpark! So a quick assembly and test (at night, but using a halogen light source). 3.249v output (not 3.3v) That's because I don't have the exact resistors I used in the schematic, so I got as close as I could get with the ones I had available ! The Supercaps haven't arrived yet, so I can't perform a full test. The little solar panel performs as expected. 1.5v @ approx 45mA.
