Cool, how did you etch it?

To get the artwork to transfer, I taped the clear plastic to my old ipod touch and turned up the brightness. Funny thing, it can still sense fingers through the plastic. I made an engraver out of an old motor I had sitting around. It is a low RPM, high torque motor, so it's almost completely silent. And the motor has nothing on the end of it, just a spindle. I connected it up to a lipo battery to power it and put a low voltage alarm on the battery. I may make a whole set of these tools for different sizes of etches. If I do, I will be making one with a small tip and high RPM next for detailed work. I have one with a small spindle around 0.2mm diameter that I may use next./I'm doing this for fun right now, but later if my parents find out about this and furry, I might be able to do commissions.
