sphere spins, but in wrong plane; around wrong axis
Magnetic sphere is N38, diameter 1" (26 mm). Coil is a basic vortex coil, 120 notches; stepping 41, aready energized with 180° phase-shifted square wave signals @ ca. 13 Hz at start of video. Powered by a 12 V car battery, with a 21 W car light bulb as load in each circuit. Signal generation by sqare wave generator, 50% duty cycle. I use a DDS20 digital square wave generator which I bought from 1&bereich=&marke= Signal B is produced by a NOR-gate, so that it should be exactly in phase opposition to signal A, that is to say while A is ON, B is OFF and vice versa. With my signal generator I can only change the frequency. No alteration of duty cycle, phase shifting or other fancy stuff. The sphere spins with good torque, i.e. there is a lot of friction between the sphere and the white stone slab, which lies under the coil. More on in forum thread "Marko Rodin"

Stovepipe water heater
Intent here is to utilized the galvanized pipe as means of making the coil. It will not be installed anywhere. Further intent is that the coil should not make any direct contact with the stovepipe, and that there will be an aluminum shield surrounding the outside. Although I mention heating the domestic water, the primary goal is to transfer heat from the stove location to the radiator that will one day be placed at the coldest end of the house. The system design calls for continous circulation through that radiator with a tap off of it somehwere to feed the existing water heater.

Ball magnet on copper rail
This is a sort of pendulum like thing. A 10mm magnet (N,S) ball swings over a copper rail. It runs on the solar SS1CC circuit in the shadow. See also : For a SS1CC PCB look at my website : You can download my music for free :
