I needed to finish up the light tubes today for the demonstration in the afternoon. I wired all the pigtails from the end of the tube into a DB-25 connector. Since I had not labelled the wires, I had to test each LED so I could wire them on the connector in order. Not such a big deal. I got the whole setup mounted on the bike. For the demonstration (since I didn't have the computer finished) I just wired up a couple DB-25's to light up all the blue LED's that face backward. It looked pretty cool, especially at night.
I invited everyone who provided music or made an effort to provide music to my house to see the bike. Jon Peone (XLTieRack) and Jessica stopped by … I guess the rain drove everyone else away. It was a pain in the butt putting things together in the rain, but at least it was a good test. They thought it was pretty cool although the wet ground was pretty terrible to try and ride on. The sound system was in place with most of the finished music on it … all running off batteries. I was using a mostly-dead 12-volt sealed lead-acid battery (probably with 2 amp-hours instead of the original 7) and it ran fine for about 4 hours, powering both the sound and half the blue LED's (which would be about typical given the light system I plan to use.)
