Modified the light for my bike, the old one gave good light but was boring and only shone forward. And it stopped glowing when the bike stopped.
The bike itself is o continously ongoing project, got it as a wreck from a friend this summer. I stripped away all the broken parts, replaced them and polished the frame a bit. A instructable on how to do that vill come later.
Step 1: Copperwork
First we start with the copper. I chosed it because i like the material, i had som pieces laying around and its easy to work with.
The spoons handle was ripped off and the flanges rolled up. The piece of tube was cut of in the middle and flattened on one side.
Step 2: Cover for the Back Light
A piece of plastic is beeing sawed to the same diameter as the copper tube.
It could quite easily be bent by warming it with a candle and shaped over the back of a hammer.
Sorry for the missing picture, i dont show what the screw is fastened in. Its a piece of copper that goes all the way back to the hole.
Step 3: Electronics
A rectifier, voltage rgulator and a 0.47F capacitor to make the LEDs continue glow after the bike has stopped moving.
Nine bright light LEDs was taken from a discarded flashlight and melt-glued in the old reflector. The rear light has six red LEDs glued directly to the plastic cover.
Step 4: Ready
Mounted on the bike. Make sure the brake arm is securley fastened, if it gets lose the brake might fail.
