This is perhaps a partial replication of a Dr. Stiffler’s device he calls the ‘Stiffler Loop’. His device lights LEDs using an arrangement of coils and diodes that are driven by a MHz signal from a bench top signal generator. What I show here might be that device but I am driving it with a Slayer Exciter instead of a signal generator. The Slayer Exciter shown here is a commercial unit called a ‘Musical Mini Tesla Coil’. It is an inexpensive China kit that can be purchased online thru several outlets.
Here is Dr. Stiffler’s video on his ‘Stiffler Loop’ device: https://www.youtube.com/watch?v=XhdfwmeWevs:
