As simple as it sounds. Just trying to get the ratios right before I throw everything together. Deets:
28 LEDs, all probably 30mah max
Power source: usb plug
Target: led array for macro photography. (Also means no flickering pwm dimming)
Resources: scrap parts
If none of these work designs function within the next hour, im gonna slap a few 100ohm resistors on the input and call it a day. The goal is to get it done.
