AS LONG AS THEY'RE THE SAME COLOR! Electricity takes the easiest path. Absolutely beautiful tutorial: http://lsdiodes.com/tutorial/ It's short and it explains everything. --- Quote --- How do I rig up a switch and leds to a battery? --- End quote --- Get a battery pack with wires first of all. Then, wire them up the same way as you would with a PSU, red is positive, black is negative(ground). |

So, I guess the real question is how many 5mm Blue 5900mcd LEDs do I need to properly illuminate a transparent blue trackball? Is there a better Blue LED choice? is 5mm overkill? Should I look for the THC3 11000mcd LEDs? |

I think that 2 regular blue ones should do the trick, especially if you buy a cheap dollar-store flashlight and use the shiny plastic reflector. |

Or you could use the 5V connection on your keyboard encoder... |
