Works a lot better and has been around a long time.

From reading the comments there it seems newer RPi (>3) don't work for this or mangle the GPIO port in some way to prevent this. I do have some 3s lying around so I may try this soon.

Just to see if it would work and then a little science demo for my kids. I never did it outside of the house.
