I came up with this idea a few years ago because I had a lot of scrap Lexan sitting around and I wanted to know what I could do with it. At the same time I was building a great many circuits and going through the expensive Radio Shack proto boards, wishing I had a cheaper alternative. Then I had the idea to solve the 2 problems with my left over Lexan pieces.
Step 1: Gather all the supplies.
1. 1/8" Lexan sheet. (8x10 from Home Depot is only $3.89)
2. Circuit components (For this ible I only used 1 resistor and 1 Blue LED)
3. Tool for cutting Lexan. (Next to the Lexan at Home Depot)
4. Solder and solder iron.
5. Tape, glue, a lighter and candle.
