jeff-o won the grand prize in the Gorilla Glue Make it Stick Contest! His awesome Desk Lamp won him a laser cut iPad. After chatting back and forth with him for a while, he sent me some images and showed me how he wanted it laid out. All I had to do was etch.

I did an initial run on some trashed clear acrylic sitting around the office, to make sure everything matched up, and a second pass on tape, to make sure everything would be fine.

I encountered one major problem. The curve of the iPad, is enough to offset the focal point of the laser cutter, rendering certain parts unetched. I had to do two passes.

The first pass was at 100% speed and 50% power, with the focus on the highest part of the iPad back.
The second pass was at 100% speed, 25% power, with the focus on the lowest part of the back.

The etching actually came out perfectly!
