What’s the worst thing about winter? If you’re as indoorsy as we are, then static electricity is probably pretty high on the list. It can ruin your chips, true, but you always wear a wrist ground strap when you handle those, right? But away from the bench, every doorknob and light switch is lying in wait, ready to shock you. If you had an anti-static ring like [LaPuge], you could be watching a tiny neon bulb light up instead of the air between your poor finger and the discharge point.
The ring itself is printed in TPU 95A filament for comfort and flexibility. There isn’t a whole lot to the circuit, just a neon bulb, a 1MΩ resistor, and some copper tape, but this piece of functional jewelry has the potential to spark up plenty of charged conversations. Zap your way past the break to see it light up against a door handle.
If you want to light up neon bulbs all year long, build a field of them and wave them near your Tesla coil!
