And it only took a few hours and about $11.00 spent at Fry's (I had a couple of the required components laying around already). Works like a charm! Anyway, after running a small LED array it's apparent that the bulbs were going to be a little too bright. The main offender was the translucent yellow button as it doesen't seem to block as much as the red one. Another 56 ohm resistor inseries dimmed it a bit, but the best results came from using the old 'sandpaper scuff' trick. They'll do. Steve |

If you're running LEDs within their limits, they should last longer than your CP. |
