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.

Step 3:

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

Step 6: Completed Light.

Done!

Awesome idea... the only problem I can see is that there are couple-second periods where there's no rear light. Not critical if there are other lights/blinkies on the back of the bike, but could be dangerous if not.

you can make it scroll a lot faster and use a longer message. then the off period is very short.

Ah... sweet. I've never actually seen one of these tags, but that seems like a good solution.

Don't make image notes that are completely covered by another one!
