Spoke POV is an easy-to-make electronic kit toy that turns your bicycle wheel into a customized display! The project includes a free schematic design, open source software for uploading and editing stored bitmap images, and a high-quality kit with all the parts necessary to build your own.

Tired: A red blinker on your seatpost
Wired: Programmable full-wheel images in any color

Specifications and Features:
  • Can be used with road, mountain or BMX wheels!
  • 30 LEDs on each side (22 for BMX) x 256 radial pixels
  • Runs on 2-3 AA batteries for 10 hours or more, assuming 3000mAh alkalines and 50% image coverage.
  • Can run on rechargable NiMH AA's
  • Comes with high-brightness red/yellow/green or blue LEDs
  • Automatically shuts off after 3 minutes
  • wxPython based software runs on any Linux or Windows or Mac with Parallel port or serial port
  • Design is all through-hole parts, perfect for a first time kit builder.
  • With one spoke, total persistence at 15mph. Two spokes, 10mph. Three spokes, 7mph. (Assuming a mountain bike wheel). Looks cool even if not completely persistant.
  • Great for safe riding at night, provides excellent side visibility.

Step 1: 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:
<p>this would be cool but kit is discontinued </p>
<p>Very nice....</p>
<p>AWESOME !!</p>
<p>I'm afraid 2 strips needs 15km/h and 4 strips about 8km/h. look at this http://www.geekled.com/led-wheel-lights</p>
What is the minimum speed required by this to produce a clear image?
i think i read on her site: <a rel="nofollow" href="http://www.ladyada.net/make/spokepov/">http://www.ladyada.net/make/spokepov/</a> if you have 1 SpokePOV you need to be going (i think) around 14 MPH to see a clear image, i think 2 SpokePOVs you need to be going about 10 MPH and 3 8MPH (i could be wrong)<br/>
<p>And is it a problem for installing more SpokePOVs when going faster. So when you install 3 sets and will still go about 14 mph?</p>

<p>I actually just checked their website. You have to ride 15mph to see the design if you only use one kit on 1 wheel. If you use 3 kits on 1 wheel, you see the design at 7mph.</p>
<p>how fast do you have to ride to see the design?! Looks like super fast.</p>
<p>Hi, I've added your project to the &quot;Top 5 Incredible Bike Projects&quot;</p><p>This is the link If you are interested:</p><p><a href="https://www.instructables.com/id/Top-5-Incredible-Bike-Projects/" rel="nofollow">https://www.instructables.com/id/Top-5-Incredible-B...</a></p>
<p>With what software/programm was the PCB designed? Interested because of a similair school project!</p><p>Thanks in advance!</p>
<p>I want to make this one for my license project . If i have any questions .. who can i talk to ? </p>
<p>Pretty cool project! =D</p>
<p>das bosss</p>
<p>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. </p>
<p>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</p>
Can you use this on car wheels?
<p>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. </p>
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? <br>
<p>Now, to find a way to run this off mains and motorize the wheel... cheap outdoor digital signage!</p>
<p>I might give this a try. Thanks.</p>
i was wondering if the batteries would fall out if you went too fast. Would they?
Omg ladyada, you totally used the same terms from Wired magazine. Awesome way to make a long story short! Haha
can I use 25LC1024 instead of this EEPROM?
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? :)<br><br> 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! :)
kits for sale <a href="http://www.adafruit.com/products/5" rel="nofollow">http://www.adafruit.com/products/5</a>&nbsp;again, soldering required
1 how mutch does this cost<br>2 can it be put on a chaos freestyle bike<br>3 can you make and sell them ?!?!?!?!?!?
I have the same bike ... $38 <a href="http://www.adafruit.com/products/5" rel="nofollow">http://www.adafruit.com/products/5</a><br> some soldering required
gggggggoooooooooo ccccccchhhhhhhhhhhhheeeeeeeeeelllllllllllllllssssssssssssaaaaaaaaaaa!!!!!!! <br>
how does it handle the weather and or the elements?
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?
Thats sick! awsome great job!
What would it take for you to just build me a pair of the pac man lights and send them to me? I really serious about this.
same here. but ill pay what you want.<br>(between 0.01 and 20.00 )<br>not like 1,000,000 $
Anybody know a way to put this on a car wheel/legality of doing so?&nbsp; I would love to put this thing on the wheels of my wip EV conversion...<br />
thoes cost a fourton to but the tires with this built in.<br>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<br>
