From this thread I built a pair of LED turn signals that'll do for that application.
As an indoor light for an RV, the LM317 regulator with 15 ohm resistor to set its output, driving three parallel strings of three LEDs just ain't bright enough. (I stuck the all clear prototype in place of bulb #1 on a dual bulb fixture for a night light that won't drain the battery.)
Sooo, what sort of fancy gee-whiz circuits can push some more photons out of 5mm white LEDs without frying them?
Forget the simple stuff with regulators and resistors. Let's see the 'overclocking' stuff. :rock: I still have a lot of these LEDs to experiment with!
