--- Quote from: fogman on August 16, 2004, 03:05:55 pm ---Has anyone used an old USB cable, cut the socket off, bought a $3.00 LED from Radioshack and hooked it up to the red and black wires on the USB cable? I think this is the cheapest Trackball lighting system, but before I go and break something, I wanted to know if someone else has done it. --- End quote --- First, NEVER get LEDs from radioshaft. They suck. You might as well close your eyes and imagine it lighting up. Second, never connect LEDs directly to a power soure. Always use a resistor. (unless it specifically says not to. Third, go with power suply hookup over USB. It's too easy to fry USB, and it drains current from anything else on the bus. |
