here is a slick hack involving a bicycle wheel and a persistence of vision toy.
one thing that’s really cool about this one is there is a second led row that blinks out bitmaps backwards on one side of the wheel. this lets you print out text messages and have them be readable from both sides. it appears to work really well — i’m thinking that the author is probably not a republican

When is someone going to make a sweet POV globe? All you need is a ring of LEDs in a plexi globe, and a way to regulate the speed of the rotation — maybe a stepper motor? An added bonus is that blue and green map pretty nicely into land and water.
For extra credit, have it be able to speak 80211.b or Bluetooth to plot geolocations. Combine that with IP plotting via http://www.hostip.info/, and you have your browser history displayed on the globe. :) Maybe the geo points could be in red (but if you have R, G and B LEDs, you might as well make the whole thing full color)…
you might google “propeller clock” for some earlier work on pov.
Actually, I’ve had that idea for a number of years. A small pancake generator, with a counterweight. From this, you can generate power, and sense wheel speed. An array of LEDs, you’ve got a message. The problem is teaching a ghetto-boy to program the thing. *Maybe* in this day and age, with a USB interface and some super-simple Windows software for them to run on that stolen laptop, it could be managed.
It’d be real interesting to see what happen if the generator armature locked up at 75MPH. Prolly a little wheel bounce :)
I’ve always considered more as a hubcap type item than a wheel rim replacement system. Great for those old El Dorados and Pontiacs with factory wheels. Wouldn’t work so hot on mags.
“some of the capitol police even thought it was pretty funny” – All it will take will be one who doesn’t. Someone might think that it was patriotic to do a stick in the spokes which would probably hurt the display and definitely hurt the rider. Having been ‘over-the-falls’ and breaking both wrists, I recommend that you avoid this. Great Hack! Quick – start selling spinner wheels with radio to a keyboard inside!
“Someone might think that it was patriotic to do a stick in the spokes which would probably hurt the display and definitely hurt the rider.”
i’m not too woried about it. there’s plenty of other things: drunks, cellphones, car doors, bike theves. maybe out in the sticks/suburbs it’d be a different story.
I will swear up and down that i saw a set of spinner rims with an identical display a few weeks ago on one of the ESPN 2005 auto shows (chicago or los angeles).
The spinners do exist. I saw them on a tv show about all the newest things at the SEMA show.
well, I like the hack (it’s pretty clever, and if i had the time and patience i’d go do it to my bike)… but i don’t like the phrase in there… Bush rocks.
Haha… Jenna Jameson. =D
Cool. apparently you can add leds to anything.
What happened to hackaday links. I kind of liked those.
There was a set of rims at sema with this feature. I’m to lazy to find a link on my treo.
Here’s a link to the wheels from the SEMA show. It’s the third set of wheels down (it’s an Autoweek article.)
I once did a 1 meter across POV display, then a 20 cm small one, and now I’m working on a dead silent blue one, on a 22.5 cm clear acrylic disc. Check the light projects on my homepage (and maybe the other projects too)!
There were two nearly identical photos of the POV in action on the site. Thanks for choosing the f**k Bush one. Always nice to be reminded of politcal hatred.
in all fairness, the photo i posted was the only one on the site at the time this article was written. check the flickr post date for the other two photos if you wish to confirm for yourself.
regarding political hatred: after careful analysis of the author’s bike wheel message, i am pretty certain that he doesn’t hate politics.
one might say that his pov message amounts to stubborn persistence of vision, but i welcome you to interpret it as point of view.
Hey you with the globe LED idea… it’s been done. I saw one for sale at the circuit city in a Utah mall. Just my two cents. But i think it would be cool to make a multicolor one, preferably incredibly gigantic, and put it in a half- sphere room, and have it rotate around the whole room, shining to the center, giving the illusion of something all around you, and maybe play a movie on it or something… Just my ” think it would be cool”
Here is another POV item, http://www.audiovisualizers.com/library/store/iball/iball.htm
I was working reverse engineering the communication protocol for a while, but work eventually took over all of my time to mess with it.
re: #15, 16
I believe you about the dates, so please accept my apology.
I really enjoy the site, which is why I found the overt political “message” disheartening. The stuff you post here is inspiring, there are a million other sites I can visit to see someone ranting about politics. At any rate, I was wrong about the photo attribution, thanks for reponding.
I hope someone reads this in time. I have a time-sensitive possibility for a deal on a PIC programmer, but I don’t know if it will handle the 16f630. The documentation says it supports, in the 16F series, the 16F627, and the 16F628. Do you think that will suffice? Here’s the full documentation:
MHT Wheels makes wheels for autos like this. Their website is: http://www.mhtwheels.com/ but these wheels are not listed on their site yet. These are the ones seen at SEMA, I’m sure you can get them but defenitely not cheap.
#20 oh come on joe. (i assume) you’re a big boy. you can handle a little free speech. heck, if you want i’ll mail you a pic programmed with whatever pro-bush message you like.
Wanna see more P.O.V. !
An Analog & Digital propeller clock i made!
It isnt Real its just because your so awfully slow!!! ;-)
