Since many of my classes this term will be at night and after seeing how cheap EL wire is, I decided to add some to my bag, since many of my classes this term will be at night. This will also increase visibility when using it as a bike bag.
What You Will Need:
EL Wire: To illuminate the edges of the standard matrix you will need 10' of 2.2mm wire
DC-AC Inverter: the EL wire I ordered came with an 3V (2AA battery) inverter but you can build
your own using the wonderfully written instructable How to Add EL Wire to a Coat or Other Garment
Screws: see the third step for more info.
