Make Your Own Speed Vest To Show How Fast You're Going

It's often difficult to gauge how fast a bicyclist is travelling from behind, especially at night. To correct this problem, Mykle Hansen created a light-up vest that shows his current speed.

Using a standard speedometer, the vest sends the speed through an Arduino and lights up electroluminescent wire digits on the back. The lights are bright enough to both catch a drivers attention and warn them of your current speed, which is especially handy if they're planning on taking a right-hand turn after passing you. It's a bit complicated to get everything working together, but the results should help keep you safe. You can find the whole how-to guide over on MAKE magazine.

    "... a right-hand turn ..." should probably be left-hand in Australia. :|

    slower than a car.

    All this effort would have been better spent buying some flashing lights.

      Actually, that's part of the problem :) My bike can easily reach 60km/h with the help of a light hill ;), and cars will actively speed up to 80km/h to pass me :-/

    Maybe should have lit the "My Speed" bit. The numbers by themselves is just going to confuse motorist.

    Actually in terms of safety this is heading in the wrong direction. It is all about relying on someone else, the motorist for your safety. Good backup plan but not something you want to rely on.

      when cycling i would sya 90% of your saftey is relying on someone else. If this assits them then i would be all for it, although i would suggest object fixation would possible make drivers vere towards you as they examined the pritty lights.
