Check out Krux’s 2kV ring launcher, Project Hathor. He writes:
Have you ever wanted to shoot disks of aluminium forty five feet into the air at the press up a button? Do you like experimenting with high energy physics, and learn about things such as impulse generators, charge circuits, Lorentz force, electromagnetic induction, and how to build this all in a form which is safe, and looks sharp. Well if you are like me, the answer to all of these questions is yes. Which is why I set out to build a ring launcher demonstration project, which I have named Hathor, named after the Egyptian goddess of the sky.
Project Hathor is a 2kV ring launcher, built for SYN Shop. It’s designed to launch rings, i.e. aluminum hard drive platters, by generating a large magnetic pulse.
