thanks! i love the monovelo. currently i am also trying to reconstruct a better tire (the current one is a solid rubber tire all the way around, it has a lot of drag...) so it is tire-less. if i get the leds installed before the tire is finished i wont be able to actually ride it quite yet, so no video in motion til both parts of the project are done :(
burning man is definitely in thought....
the wheel is purchased, so i did not build it myself. the company that makes them is called monovelo, located in china. http://www.monovelo.com/
they built these things specifically for the chinese olympics in '08, then opened up their creation to the general public for a hefty charge. they have the option of buying it with, or without, leds already in it, but the leds they put in are run off a 3.7V cell phone battery and are your basic leds. they only come in one of three colors, red, white, and blue.
as for the zero-crossing sensor...
yes, this had been a thought. it would be pretty cool to do that. unfortunately this is totally my first arduino project already, so i dont know where to start. i was thinking about coming back to that some time in the future after finishing just getting the leds in. but making it appear as if the wheel wasnt rotating was exactly what i was planning on going for with that.
if you could point me in the right direction though, i can start taking a look and maybe work that into it earlier than expected.
the point of this project for me was
1. to make the bike look cool, but also
2. to learn arduino (always wanted to)
so the zero crossing thing was a thought, as well as putting on a display shield... http://adafruit.com/products/714
the idea for the shield was to have it removable for when riding, but to be able to program several different patterns into the wheel, and in the middle of a ride (if i stop of course) pop the shield on and be able to select and change the pattern to whatever my mood feels like :P
