    Hello,

    Maybe I’m wrong but on the datasheet the diodes are connected on the other way.

    Please confirm.

    Be aware that in some places the cops don’t take a shine to having flashing blue lights on your bike, as they feel that is strictly THEIR gig.

    In the podcast feed over at http://blog.makezine.com/archive/make_podcast/index.xml You link to the PDF for this project but forgot to include the video in the feed.

      @ joecr – The video link is right above the PDF post.

    Flashing lights make it harder to judge your distance and speed. It is illegal in most of Europe.

    @mzi – It’s really so others can see you not so you can see where you are going.

      Dear Kip,
      If you want to cross a street, it’s handy to know when you can cross the street. Knowing how far and how fast other traffic is going is helpful then.

      Florida might not be much of a biking area, but where i live there’s more bikes than cars, and have seen many problems regarding the flashy lights. It’s illegal for a reason.

    Try http://www.picokit.com for a cheap DIY bike light – the front has flicker mode and back is just awesome visibility. Both come with Pre-programmed microchips. Just solder and construct them! Mine work great on AA rechargeables and both last for hours – even the front one which has heaps of power!
    The front one all fits in a 40mm PVC pipe (including the 3xAA batteries) with 19 UltraBright LEDs it blows this thing away.
    The back one is oval shaped with a funky pattern happening for high visibility.
