    B&M Cyo Troubleshooting & Repair

    I ended up gutting the light, replacing the dead PCB with a simple bridge rectifier and capacitor circuit, plus switch. I did harvest the supercap and the LED from the original circuit. It now might not be quite as bright as a stock Cyo, but it's been working great for over a year.

    Magnic Light: contactless bicycle dynamo light

    That reviewer is my friend Carlos. I have seen these lights, and they do indeed work. The dual taillights on his bike are especially nice. No standlight function, though, on either the front or rear lights. I took a photo of his lights...

    Let's design a road front light beam

    This guy has made some really good progress on the quest for a cutoff beam: http://forums.mtbr.com/lights-diy-do-yourself/build-thread-double-xm-l-road-lights-746967.html

    Let's design a road front light beam

    Here's the money shot: http://www.dealextreme.com/customerphotos/quarantined/201109/82138-12514670-7668-4684-acef-f11f03b3df04.jpg There is a bit of heatsinking, but it's not exposed to the moving air outside the light (unlike, say, the B&M Cyo).

    7006 BuckBullet for Dyno Light?

    The new(?) 7006 BuckBullet from LuxDrive looks interesting for use in a dynohub-powered bike headlamp. DC input, AC output, up to 700mA regulated current. http://www.luxdrive.com/download/?dmid=1379 http://ledsupply.com/7006-h-700.php Think it might work?

    B&M Cyo Troubleshooting & Repair

    That's what I'm thinking of trying. Steve, I can post larger/higher-res photos, I just didn't want to clog up the board. Tell me which photos you're interested in... There definitely is a burn mark on the edge of the PCB -- you can see it in the first of the last set of photos I posted...

    B&M Cyo Troubleshooting & Repair

    Borrowed my wife's camera tonight, here are some better photos... The full-size originals can be found at http://www.flickr.com/photos/jimg/ My light seems different than others I've seen, in that the tail light & main wires exit the PCB on the same side as the supercap....?

    B&M Cyo Troubleshooting & Repair

    I thought all versions of the Cyo use the same LED? I think that's it, yes -- right on the edge of the board. So it's just a resistor? Why would that kill the entire board? I'm thinking of trying to unsolder/remove it, and see if the light might work without it (assuming that it's shorting...

    B&M Cyo Troubleshooting & Repair

    Here's a photo of the guts of my Cyo. Sorry for the blur... The fried component is right at the edge of the PCB, under the black wire in the center of the photo. You can see it better highlighted at http://www.flickr.com/photos/jimg/4869751676/

    B&M Cyo Troubleshooting & Repair

    The PCB on the light I have actually looks slightly different than the one in those German photos. I'll have to snap some pics of it tonight. The fried component is on the very edge of the PCB, right next to where the tail light wires are soldered, but on the other side -- underneath the big...

    B&M Cyo Troubleshooting & Repair

    A friend gave me a dead B&M Cyo headlight to play with. I've opened up the unit and verified that the LED is still good. Near where the tail light wires are soldered onto the PCB is a tiny burnt component -- I'm guessing that the tail light wires (which weren't connected to anything, nor were...
