Messenger bag LED matrix keeps bikers safe at night

Get a little more exposure than one under-saddle bike light can provide by building your own LED enabled messenger bag. It looks like the bag itself was fabricated from scratch by [Andrew Maxwell-Parish] rather than altering an existing bag. He had a few goals for the project, the most interesting of which was to make the electronics removable. His reasoning for this is so he can get the bag past security at the airport.

The design is quite simple, there’s a large flap which is attached at the top of the bag and has a couple of clips at the bottom to keep ti closed. On the inside of the flap he sewed a snap system which holds one piece of material on which all of the electronics are attached. The Lilypad system is used (it looks like the original hardware and not the FLORA upgrade). The main unit is sewn to one side, while the Charlieplex LED matrix was attached in a grid centered on the flap. The lights shine through the orange fabric, keeping them fairly safe from the weather and giving them a reddish hue.
