I was re-published on TreeHugger!!! http://www.treehugger.com/slideshows/gadgets/how-make-led-turn-signals-your-bike/
Turns out the guys at CleanTechnica and WonderHowTo blogged about this without telling me first. Not sure if I should be upset or happy, haha. Check it out:http://cleantechnica.com/2012/10/17/led-turn-signals-for-your-bike-by-a-9th-grader/http://cycling-lessons.wonderhowto.com/how-to/add-led-turn-signals-your-bike-for-safe-road-cycling-0138678/
I made a schematic using Upverter!
This should help a lot of people.
Update 8-5-12: Thanks so much guys for the homepage feature AND the newsletter feature! I've always wanted one of my instructables in the newsletter!
Hand bike signals are boring, and who doesn't love electronics and LEDs? I don't do much road biking where I actually need turn signals, but they look cool and are fun to make. Also, they go great with an Altoids Bike Headlight on the Cheap! (That's another one of my 'ibles.)
