One might cheerfully make an electric chair for some folk, if only one could be *certain* they'd not decide to sit elsewhere when the chair was connected to the mains...
Will the swivel base of the ejector seat have some sort of aiming device?
I'm surprised no-one's mentioned "The Boy Electrician" yet. I've got the
1960 reprint of the 1955 edition, which prophecies that computers will use transistors, and list illuminated mirrors as an example of a household appliance in the electrical age.This book ensured that only moderately competent and lucky boys survived to manhood: there isn't a safety warning in it, and the construction of an open potential divider across the mains (AC or DC) was encouraged.
And there are plans for a Wimshurst machine.
I've just spotted the safety warning in it. After telling you how to buy an X-ray tube and a platinum-barium-cyanide screen, you are warned to be careful not to over-expose any part of the body.

No, but Scientific American used to have a regular feature with practical things to do- there was a water drop spark generator that I set as a Christmas A-level exercise when I taught physics. Made about 90V to ignite a neon bulb. They also had a 'partly-baked ideas' column. Not nuuty enough to be half-baked but not quite finished.
You might find back-numbers. This would be 70s and 80s I guess.

"The Practical Scientist", IIRC.
The articles were published as a book. I have the CO2 laser one here somewhere. Never built it, needless to say.
