Not happy with the warm-white LED and its brightness, I ordered some 40.000mcd LEDs along the BPW34 photodiode for gamma-ray detection, a shorter potentiometer and some extra long pin headers. I previously design the LED board with 123D circuits but want to train/force myself into eagle and use OSH Park directly (saving the fee comes in handy, too). My first board will be an attiny85 pcb for a charlieplexed 5 LED bargraph which I intend to control over IIC or soft-serial. I hope I will be able to solder those smd parts and not connect the via on Resistor 3 with both poles.
