This thread needs more hardware.<p>I'm making bike lights. First a little story. I was late to class one day in March, pothole season. I was cruising in the drops, when I came up to a T intersection. A van pulls up, and stops at the stop sign. As I approach the intersection, I see a pothole, swerve to avoid the hole, and the van pulls forward. I have about 1 second before I hit the van, land with my back on the hood, slide onto the ground. I'm lying there for a moment, trying to figure out what just happened, wondering whether or not anything is broken. I wiggle my fingers, wiggle my toes, don't feel any pain. I stand up, the guy gets out of his car "Sorry man! I thought you were turning!" I say I think I'm fine... I go look at my bike - it's still upright, the front tire got wedged in a rust spot. I grab it out, hop on, and ride. I couldn't help but laugh the rest of the way to class.<p>That's the day I decided that bikers and automobiles need better communication. So I made a bike light that's easy to use, has front & back blinkers, brake lights, turns on when you ride (so you can't forget), a bright front light, USB rechargeable, 3400 mAh LiIon battery. I made a 3D printer to print the parts, I did the PCB design, physical design, and software. It's pretty damn cool. I ride pretty regularly and recharge it about once every three weeks. It's surprisingly water resistance - I am a little scared of selling this to people as I didn't know how it would handle water, but I've taken it through two large storms, one with huge puddles splashing all over the cases, and the light handled it all in stride.<p>Here's the images - <a href="http://imgur.com/a/EUzXm" rel="nofollow">http://imgur.com/a/EUzXm</a><p>I'm stalling on it a little bit right now - there's not a very good way of bootstrapping into manufacturing. I could 3D print the cases and assemble the boards, but each case takes about 20 hours to print (on my fiddly printer). There's ~100 components too, which is a pain for manual placing and reflowing. I have a couple other designs brewing that are simpler and lower cost, but without all the fancy features. Speaking of which... I have to go get some interrupts working.
