Introduction: Scrolling Rear Bike Light.
Bike light made from a scrolling convention badge and a old broken bike light.
pretty simple stuff.
Step 1: A Scrolling Badge
This little scrolling badge is for geeky convention goers. i got it from ebay a few years ago.
I would just use this the way it is, but the battery compartment is on the bottom and could fall out and get lost from going over a bump.
Step 2: Take Apart the Badge
Remove the tiny screws from the badge. take out the board.
Take all the guts and metal battery clips out of the bike light.
Step 4: Make Everything Fit
I placed the circuit board on the lens. then drilled a hole to match where the on/off switch is.
I had some plastic circuit board standoffs that were the right size after i cut part of it off.
the switch works well, you have to open the light to program the message or change the battery.
Step 5: EXTERMINATE!
Destroy any plastic parts that get in the way of the light closing properly
