This instructable is for my lasercut LED candle design that you can download from Thingiverse. It’s a simple but useful electrical circuit that you make out of wood and copper tape (or cardboard and aluminum foil – I’ll explain later about alternative materials). We make this at Ace Monster Toys in Oakland, CA for our Hacker Scouts program, where kids 7-14 put it together themselves. Young kids may need some help from their parents. A little manual dexterity is required to get the parts to line up.
