A clamp for heat sinking became loose and touched the pad of a resistor. R20 exploded. It looks like it might be a 2.2 ohm, but the board looks swollen and cracked underneath the resistor. Even if I go to the trouble of getting the resistor and replacing it (I never knew how helpful Radio Shack...

I changed the head lights to motorcycle lights on bars attached below the rear view mirrors. And installed turn signals on the ends of the bars. Not too aerodynamic but quite visible. The only problem is that they are really bright.

Turned out to be a 6803.

And now we know the rest of the story. Organic Transit is out of business.

How to test before buying?

it is a Novatec wheel with "K09121200001" on it. Does anyone know what bearings to use? There are no numbers printed on the race or hub. Oh no, I just realized that the hub is most likely a custom build for the bike because it is a tadpole and only supported on one side. I asked the bike...

MadRhino, Sounds good, thanks.

The rim was fixed. It wobbles a little but it is not noticeable when riding. Thanks for the suggestions. The thresholds are everywhere now. 45 degrees seems to be the best angle, that and low speed works OK for me.

Updates: The lights are all working. Drivers are generally staying far away. A police officer shouted over her PA system that the lights could cause "seizures, you hear?". Since the light's blink-pattern is very adjustable, they are no longer in a strobe flashing pattern but a slow blink. And...

I stopped by their old factory several years ago. I was impressed with the owner and staff. The ELF looked amazing. I had already taken a test ride on one owned by a military doctor. It seemed reasonable enough, easy to pedal and steer and fairly decent on a rough driveway. I bought one second...

Amberwolf, That is a very cool idea using ultraviolet LEDs to make fluorescent colors light up at night. My one worry about that is that ultraviolet light causes eye damage. One thing I've noticed, well one of many things, is that even the dim green indicator light on my power control panel...

First of all, thank you everyone for your interesting, thought-provoking, and educational comments. I might just get a random-variable-rate chasing relay to put on the two lights. As far as colors are concerned the National Institute of Standards and Technology found that the safety green was...

Trek claims that a rider becomes 80% more visible when they highlight their feet and knees. (That seems almost obvious to me but I never thought of it before.) Of course this is not possible when riding a velomobile. I'm thinking about adding two lights to the back of my velomobile (in...

Bought a BMX rim. The LBS cut some spokes for the motor. I built the wheel. Rode for months. Last night I hit the 1.5 inch high threshold between a road and a driveway at a small angle and bent the rim. :oops: I really hate those thresholds because I've had several pinch flats from them-hence...

Ok, do you have any specific suggestions? Edit:Hmm, don't need a relay, just a switch, precharge incandescent lamp (still has high current though), SPDT MC switch for turn signals, reed switches for brake lights and controller, 12V battery for lights (or wiring 12v devices in series) and...
