The latest from Dr. Frankenbike's Laboratory....
Edited on Fri Feb-27-04 05:33 PM by BiggJawn
Where I live, if I want to get in a 2-3 hour ride after work, that usually requires riding the homeward leg in darkness. Now, my 40-something eyes aren't as good as they used to be, so I've been experimenting with different home-brew lighting systems for my bikes.

I started off with one of those LED blinkers and a Cat-Eye battery light, but after not seeing a BRICK laying in the road and getting flatted, I needed something better.

Power is no problem, other than the weight penalty. I have LOTS of 12V-7.5 AH pull-outs frmm the UPS' here at work. OK, so since I weigh 20 pounds less than I didn last fall, I'm not even gonna notice the weight.

For a front light, I have a 20-Watt halogen spot light mounted on the former reflector bracket. I'm going to experiment with a 11-Watt "Malibu" light that looks like a plastic sealed-beam and seems to have good output and a nice spread. That will give me almost twice the battery range of the 20.

Now, so I don't get rammed in the butt by some oblivio-tron in their Dodge RAM Penis-Augmentor, I took the red reflector in the rear, sawed it open, and drilled 6 holes and glued in high-output LEDS. the bank of LEDs required only a 20-Ohm resistor for current limiting, and draw 33 milliamps, so the battery will hardly notice them....Glue it back together, with through-bolts (4-40 hardware) for terminals and it looks like something you'd pay Pete White $45 for....

See what you can do when you give up sex for Lent?

1. That's crazy
If you know the physics behind your work, can you explain flux to me?...I'm trying to learn Gauss' Law right now...it's impossible to conceptualize.

2. I'm a Broadcast Engineer, not a Physicist.
The only thing I know about Flux is that solder will not flow without it, and there was a Cartoon Noir character named Aeon Flux.
