That is awesome. I guess you did the slots with a grinder?
Thanks, Tony. :D
The slots were done with a 12" metal chop saw, but the radius didn't cut through the middle. It left troughs more or less. Sprayed it all down with acrylic, picked the paint out of the troughs, poked some holes on the sides and dunked it in a ferric chloride/hydrochloric acid bath for about 20 mins. Finished the slots out with a dremel wheel. The led diffuser is a piece of clear packaging, sanded with 300 on both sides and held up by the foot switch. Without it, it looked a little cheap. Didn't have the "reactor meltdown" effect I had imagined.
