I managed to acquire some large sheets of very thick acrylic for next to nothing ($15). I wanted to create a ring of lights for a steampunk/gothic display cabinet I am making. The best thing about this project is that I found acrylic is very easy to shape/mould with a router - have a look at the results!
Step 1: Materials & Tools
Thick acrylic sheets (1" or 2.4cm thick) size is dependent on how large you want your ring to be.
Sacrificial wood (for rotating your acrylic on - there will be pictures!)
16 Colour changing LED's + 16 resistors
Transformer (12 volt 1 amp DC) Walwart
Router with router table
Drill bit and drill
Solder and soldering iron
Glue and glue gun
Electric Tile Cutter
Step 2: Cutting the acrylic to size
First cut the acrylic to the size you want. I cut mine into rectangles of approx 50cm x 18cm using an electric tile cutter (with a diamond blade) - don't use water, it cuts better without! My acrylic also had some old images printed on them, not very good ones I'm afraid! I made four rectangles. To clean up the sides I used a straight edged router as you can see in the stack.
