Step 1: Intro

Picture of intro
These instruction assume you purchased the kit or at least the PCB. All parts are through-hole and this should be a very easy project, even for a beginner. Still, if you've never soldered before, this tutorial is really awesome. If you're part of the new streaming-video-generation, this set of soldering mpegs may do you right:

hi. looking on the adafruit site for the kit, however im wanting to mount this on my ceiling fan, which im not sure works because of speed issues, also, the magnet that triggers it probably wouldn't work. so id like some ideas on what I should order and or do to mount this setup to my ceiling fan. thanks in advance.

how/where can i change this to be RGB? seems limiting and silly paying so much for a kit of one colour when i would happily pay more for RGB

Can you use this on car wheels?

Forward facing lights can only be withing a certain range of white or yellow in many states, and back lights are strictly red, except for when reversing. These laws are nullified, however on private roads and parking lots.

I would say that if you used thios on car wheels you are setting yourself up for a mighty big fine. Most states do not allow you to use any auxiliary lights in the colors of red, blue or white because most of the safety vehicles like police fire rescue us those colors.
how about purple?

Now, to find a way to run this off mains and motorize the wheel... cheap outdoor digital signage!

I might give this a try. Thanks.

i was wondering if the batteries would fall out if you went too fast. Would they?

Can you replace the LEDs with Tri-Color LEDs (with red, green, and blue) to make a Spoke POV that can display all three colors? Are there RGBY LEDs that can display all three colors? And where can I buy them?
try making three w/ one red, one blue ,and one green and burn respective color channels onto them

are these for sale?? Like would you be willing to make them and sell them? :)

I just bought a really awesome custom bicycle I designed at: www.villycustoms.com and the only thing I think could make it better and more unique than it is right now, would be this, this is great, specially for Christmas time! :)

What if your computer isn't old enough to have one of those ports
How do these kits hold up with impact? like if you're hopping a curb or going over a speed bump? Also, can you waterproof the boards at all? maybe use scotch guard?

Anybody know a way to put this on a car wheel/legality of doing so?  I would love to put this thing on the wheels of my wip EV conversion...
thoes cost a fourton to but the tires with this built in.
you should solder it in to your car tire to do that
its perfectly leagal, they even sell rims with that kind of thing built in
i would love to do a small one on a sport bike and a el wire jacket for a tron look
I'm pretty sure it depends on the state.
Love the chelsea fc one

In the animations above we can see how the image would look if "the observer" wold have the same speed as the bike. What happens when observer stays? In this case the spokepov will make a sort of sinusoidal motion and image may be distorted, but not sure how it looks.
