Found some double sided board in my stack of boxes! Still don't have any etchant so I used the less exacting method of grinding off the copper with a dremel. Started with a rough cut circle on the old scroll saw then used the dremel to clean it up.
Decided to go ahead and enlarge the holes for the negative contacts and use some hardware I had to attach them instead of solder in case one should break where I bent them. Made the top of the board the atty negative plane and the bottom the battery negative plane. Decided to use a Mosfet so I flattened off a section of the side of the board, bent the tab on the fet 90 degrees and soldered it to the top of the board. Can't believe the fet didn't give up the ghost from the physical and heat abuse. Trimmed off the drain pin since it isn't needed with the tab being drain also, soldered a 15k resistor across the source and gate pins, grounded the source to the battery plane and soldered a wire onto the gate. Next....oops, the gate will require power from the positive of the battery through the switch and I didn't provide for that. Whomever Hindsight is should be shot. Gave it a go anyway and soldered a wire to the side of the silver contact in place hoping it wouldn't come loose where I soldered it to the atty center pin or damage the silicone tubing insulator. Got lucky.
And of course the big moment where the rubber meets the road with the obligatory first glow pic
So here is my little squonk rocket all ready for a bath and clothing
