Joule Thief

   I think that you are missing a little something. As the Joule Ringer Circuit can light several 7.5 watt Ac 110 volt LED bulbs on 12 volt battery, which can be recharged from a small solar panel. Consuming about half as much of what the same bulbs would consume if on a grid source.
   It can light several bulbs on a single transistor no resistor circuit, and can actually light up ones house, if enough bulbs are used. One circuit can light as many as 12  7.5 watt LED bulbs, and it is one of the most useful circuits I have seen to date.
  Here is a video I had made a while back, about a year ago, but I had forgotten to do anything with it. It was one of my first tries at making a Joule Lamp. I just refound it, hiding in one of my cameras.  The camera battery gave out at the end of the video, so sorry for the cut off ending.

  Here is Lasersaber showing what his 3.0 circuit can do. Of course the use of LED bulbs is the way to go. And it will be interesting to see what something like this circuit can do with the bulbs like the high lumin one that you just ordered, Bill.

Nick:

Thanks.  I will watch the video.  Of course it is very possible that I am missing something...it happens all the time to me.  I will check out your vid and respond.  I appreciate your posting it.  Are you seeing those high amp draws that LS mentioned on his website?  Or is it that those "high amp draws" are for 1 or 7 bulbs making no difference?

Like I said, I will watch.

Thanks again,

Bill

   The 3 amp current draw was due to a problem that a resent poster had with his set up. Which he was looking for help on. He has since resolved it, now lighting two 7.5 watt bulbs, and drawing less than an amp.  Which is about right as each of those AC 110v bulbs can draw between 500 to 600 mA each, at 12v.
   All in all the Joule Ringer circuit is very useful, and can oscillate and light LED bulbs on less than a volt, if that is the objective. There is always room for improvement, which is still an ongoing thing. But, compared to what a regular inverter draws from a battery connected to a solar system, this circuit is much more economical to build and to use.
It can also be designed for 4 volts systems, and up to about 15 volts, if needed.
  It is basically a version of a modified Joule Thief, and it is why I mention it here.
I use it with 7 watt incandescent bulbs, and love it.
Here is a pic of it lighting both a 60 watt incandescent, as well as a 25 watt CFL bulb on 12v.

Thanks.  I posted a comment on your video and, I will say it again here...that is bright as heck!  Obviously, my 1.5v (or much less) HVJT circuits can not do that.  I found a good source for the rods so I may try one to see.  If I can use it on an AA battery I don't really care how many windings  I need to make to do that.  I am always searching for that happy medium between light output and longevity.  The light in your video was superbright.

Thanks,

Bill

  Thanks for your comments Bill.  I do not know for sure just how much current the 65 watt CFL was using, as it was built a while back, but it really was probably drawing more than the 500 mA that I mentioned on the video, more like a amp or so.
  I am more concerned about obtaining the most useable amount of light output possible, and not trying to keep the current draw low. My objective is to light my house, which I am able to do now, to a fair degree, even for free by using small solar panels along with the circuits that I been working on.
  Although obtaining the highest amount of light output is what I am after,  I am still very interested in a self running system, although for now this is what I can do with what I have to work with. And it is still free energy. Since as usual, my cost are zilch, as it is all recycled discarded materials that I obtain for free.
