This is an inexpensive Persistence of Vision (POV) toy, which is designed for beginners in electronics. You swing this little thing around to reveal a customizable message or image through it's 8 red LEDs. It has 4 holes for mounting on bikes, fans, and anything else that swings around. You can purchase this kit from the Make Store.
This project is the third revision of the MiniPOV. This version is nearly identical to the last version, MiniPOV2 but uses the serial port (possibly with a USB/Serial converter) instead of a parallel port, for programming. Because the programmer is built into the kit, one does not need a special "microcontroller programmer". This version can be used with PCs (Linux/Unix or Windows) and Macs (running MacOS X and with a USB/serial converter).
This kit is great for soldering beginners. To learn the basics of soldering check out this great guide by noahw. Also, here's a good video tutorial from the MAKE blog.

Signing UpStep 1What you get and what you need.
This kit is great because it's mostly self contained. The only thing you really need is two AA batteries and time. It's also easier if your computer has a serial port; it looks like the monitor output but inverted.
A note on the resistors: electrical components are marked by colors, and you'll be getting all sorts of things that look the same. Be careful not to mix them up!
What you get:
1 PCB
1 ATtiny2313 Microcontroller - IC
1 20 Pin Socket for microcontroller - IC1
3 1/4W 5% 4.7K resistors - R10-R12 (Red band)
8 1/4W 5% 47 ohm resistors - R1-9 (Brown band)
3 5.1V Zener Diode - D1-D3 (Red body)
1 Battery case with screw - U1
8 Red LED - D1-8
1 DB-9 female connector w/solder cup
1 Sticky pad
What components you'll need:
2 AA batteries
(if you don't have a serial port) USB to serial converter
The ones with the PL-2303 chipset work:
Here or here or somewhere else
What tools you'll need.
Rosin core, 60/40 solder
Soldering Iron hopefully with a pencil-like tip
Wire clippers
A vice to hold up the PCB

The only wire connection i can envision would be similar to the brushes inside a brushed dc motor.
i sold off the bike and now m in states
thnx for the help tough

and the rest of the components to make this?
I'm going to Radioshack soon and I'd rather buy all the parts there than have to wait for products to arrive in the mail.

El indica más arriba que hay que dirigirse a: http://store.makezine.com/ProductDetails.asp?ProductCode=MKPOVKIT pero, si mal no recuerdo, allà te envian a una sede web propia.
Ellos venden el equipo básico y creo que hacen envios por correo. Luego, combinando los manuales de esa sede con lo que hizo este joven, podés tener una idea buena de como armar tus proyectos.
La moda, creo que viene de Japón. Usan unos aparatos más pequeños para enviarse mensajes o dibujos.
Suerte con tus ideas.
