Sorry for the super long time in between posts. We have been slaving away on Tron jackets for the group Daft Punk ‘d. I designed and built all of the light panels. The jackets were supplied by Daft Punk ‘d. I used A4 sized EL sheets that were cut and spliced together to create the different shapes. One jacket can be run off of either 4 9volt batteries or plugged into a wall unit.
