Hello All, Riding my bicycle home tonight, I decided I ought to make a bike light controlled by a little 10F pic. I have a 9.6V NiMH rechargable battery that I think would be perfect for the job, and I'll get some super bright LEDs, but i wasn't sure how to best regulate the voltage (LDO? something more efficient?) to the PIC or how to best control the LEDs (pwm?). I think I need about 5 white LEDs for a "continuously on" headlamp, and 4 or 5 red LEDs for a flashing tail light. Should I charge up capacitors for the LEDs or something else?? I'm just an undergraduate, thus I don't have much experience in designing things like this. Any and all suggestions would be appreciated. Thank you, Scott Larson 1136 W.
