  • RE-EMF Charger - Joule thief

    For those that know about Bedini's chargers, that play with battery's.
    And those that know a little about the Joule Thief.

    I've got a little something for you....

    How about a very effective , easy to build battery charger that uses the applied energy not only super efficient, but in a sence twice !

    A charger that can charge, non rechargable battery's , rechargable battery's , lead acid battery's or Bedini's cristal cells. Without heating up the battery.

    Restoring almost dead lead acid battery's if left charging over night(s), desulfating them.

    Cost of the circuit... around 2 dollars... Now thats fun !

    Enjoy !

    Hi, Rene

    Good video, thanks. I am just learning electronics but will attempt a replication of your RE-EMF soon I hope. I am building an electronics bench now.

    I believe if you were to move this post to the renewable energy thread it would receive many more views, and comments. There are a lot of good people there, who are very good with electronics.

      Very nice! I saw lasersaber comment on youtube that he was interested in it too. To me that says it's worth checking into. This should probably be moved to the Renewable Energy section. Can you give any more details on the JT coil you use in this? Winds? core? toroidal?

        All I can say is wow! Watched the vid and decided to make one real quick. I used a 2n3055 transistor and the charging was amazing. I then tried a larger toroid worked about the same. As Im watching the battery charge playing with the resistance on the base and trying to find a balance between charge rate and heat in the transistor I had a thought...

        I pulled out the basic bi filer coil from a old Bedini monopole. I hooked it up in place of the toroid just as in your diagram. This so far has yielded the best results so far with no base resistance. Nothing gets hot!

        Time and more testing but very simple and impressive. Please make a thread in the renewable energy category as I agree it will have more ppl interested.

          Done !

          check it out.
          Glad you like my ideas...
          next.

          - A transformer setup that amplifies (if one likes... to infinity)
          - How about a generator that transforms centrifugal power into usefull energy. If talking about a COP.... How about COP 100+... :-)

            Hi gr8dane,
            Could you make a clip for youtube and link it.
            some people on other fora asked me to film my setup, which is completely boxed and sealed. lol.

            thx. in advance

              The core is toroidal. any size will work.
              I pulled a general one from an old power supply.
              Bigger cores and thicker wire allow more power to flow in the circuit.

              Just play with it.

              Mine looks like this.

              Toroid about 3 centimeters diameter, bifilar coil each 20-30 windings. I gues about 1 millimeter thick wire.

              If you connect it correct, you'll hear it humming.

                Hai Rene..i am new in this forum..i was build your charger and its work great..i have a question..can i use 16v 10 A transformer for power supply/source..?..should i change the component..?..sorry my english not good enough..
