This is one of my very first DIY project. I had the idea of making this after I shot some videos using a dSLR under relatively low light. Even with high ISO, the video turns out pretty dark since I can't use flash to brighten the video. Off the shelves LED lights for cameras is around $400 (Canadian, 2010) so it is too expensive for me. I'm wanted to make one for under $100.
First up, I need lots of LEDs. I bought 50 CREE high intensity LEDs from digikey.ca for around $30. This is the most important and most expensive part of this project. I also bought a bunch of resistors, a 5V voltage regulator, and a potentiometer from Digikey. Other items I used for this projects are a breadboard, a switch, a battery pack, some wires, glue, duck tape, spray paint, styrofoam and some plywood.
