Joule thief – RE-EMF Charger – by Rene
Charge Lead acid, non rechargables, rechargable battery’s. With this technique you can revive your dead battery’s. Super simple but very effective 🙂 Please build, test and let me know what you think ! And…

have modified regular TROS’s charging schematic, now it’s bemf hitting either LED spot-lite or charging secondary bttry
Just a bunch of things put together to make a charging circuit that is different. I use a neon bulb in this circuit instead of LEDs. An oscilloscope is used to show the wave…
Received from Johan around March 14, 2012. Shows the modified Hex Controller from Bob Boyce charging a battery, apparently from the surroundings, even as the battery is powering one motor. Posted with his permission…
Received from Johan today 11:05 am MST. Shows two motors being powered while the Hex controller keeps the battery from depleting as rapidly as without, and then recharging the battery once the load is…
This is a spinning top that is partially levitated and driven by an electromagnet pulse circuit. The top has a sphere magnet inside it that is pushed by the electromagnet. The firing of the…
using a capacitor’s case and avramenko plug as a radiant transmitter to charge another battery
This is “SkyWatcher’s” way of lighting a CFL by using a wall outlet transformer pulsed backwards with 12 volts DC from a 555 timer circuit. The circuit that he uses also places a parallel…
Two sides double rows of mags on bemf circuit running shaft pretty fast and making more voltage to charge a cap (two mags passing the coil at the time and from both sides of coil too). It would be even better to put another coil above the shaft; we sho…
