[Teodor] writes in with a unique Tesla coil he designed and built. Unlike most Tesla coils, [Teodor]’s design is able to run with a fairly low input voltage because it doesn’t use a static spark gap ...

[mircemk] has been working on wireless power transmission. Using a Class-E Tesla coil with 12 turns on the primary and 8 turns on the secondary and a 12 volt input he can send a few milliwatts to ...

Low-voltage designs with rails in the single digits get a lot of attention these days, for reasons I don’t need to detail to this audience. Still, there are many situations where rails at hundreds of ...

This “pancake” inductor wound with copper tubing forms the primary of the Tesla coil. The heavy black wire connects to an adjustable “tap” that allows tuning of the primary circuit. The elevated ...
