I recently was looking for bright LED's to stick on my rollerskates, and the only really bright ones I could find were red. This got me wondering what the brightest standard-size one element LED's of various colors are. There's also gotta be some physical reason why red ones are easiest to make brightest. The red ones I got were from Radio Schmack, and put out 2000 mcd. Also, what's the easiest way to blink a high-current LED at say 2-10 Hz? I've heard there's some way to do it with a 555 timer, but electronics isn't my strong point. Blinking LED's (that have the driver built in) seem to be a lot dimmer than non-blinking ones. -- -------------------------------------------------------------------------- | Randy Spangler | The less things change, the | | rspangle@jarthur.claremont.edu | more they remain the same | --------------------------------------------------------------------------
