New LED bike wheel lights (as seen @ Maker Faire!)…

The Monkeylectric m132s is a revolutionary bike light that keeps you visible – and in style. Its ruggedized design is perfect for daily commuters, urban cyclists, casual evening riders, BMX, festivals – anyone that wants to be visible after dark and not feel like a second class citizen.

The m132s creates full color graphics on your spinning bike wheel, and it provides outstanding visibility. The all-weather design is affordable and installs in minutes on Road, City, Cruiser, Mountain and BMX bikes. The lighting effects can be easily customized anytime to fit your style – mellow to extreme.

The m132s sets a new standard for bike lighting with brightness, visual quality, effects sophistication, user control and durability that far exceed what has previously been available.

Here’s the section on hacking

Are you a hardware or software hacker that wants to customize your Monkeylectric? It’ll void your warranty, but we’ll help!

Here’s the hardware schematic for the m132s to help you on your way: m132s Schematic.

Here’s some simple hardware hacks you can do yourself:

  • swap in a lithium battery (the existing low-battery warning is perfect for a lithium-protector – just make sure you turn off the power when you start seeing it)
  • make handlebar mounted control buttons by using magnetic switches in parallel with the on-board buttons
  • power two units from one set of batteries
  • mount the batteries on opposite side of the wheel from the unit, to balance the weight

The m132s ships with a standard Atmel AVR 10-pin connector that you can use if you want to reprogram the m132s with your own code – experienced embedded systems hackers only!

And there’s a “Let it Glow!” contest on Instructables now.

    Anyone ever heard of a STP16L596?
    Hey Dan, what chip are you actually using? :)

    Looks like the chip is the STP16CL596. Seems they left the “C out of the schematics.

    Looks like you can get them for about $1 a piece.

    Monolithic, low-current 16-bit shift registers designed for LED panel displays. The STP16C(L)596 contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit D-type storage register. In the output stage, sixteen regulated current sources are designed to provide 15-120mA contant current to drive the LEDs.

    Hokey Spokes: http://www.hokeyspokes.com/ have been around for several years, do much the same thing, and cost less.

    Of course they are only monochrome LEDs, but you can program in text messages.

    I just posted a review of these lights, including a full comparison with Hokey Spokes, on my blog.

    I shot a few videos and photos of the lights in action, and include those in the review.
