    There are a lot of new low power applications in today's devices that would be perfect for a nearly permanent battery. Smoke alarms and such have 10 year batteries now, and a lot of remotes, like for tv, car locks, and now commercial lighting would be a perfect application. Clocks too.

    Sharing a new project I've started. Trying to convert a solar LED table lamp I purchased on Ebay to run off of some small crystal cells.

    Here is a link to the lamp: Solar LED Table Lamp

    It run off of a AAA battery by default, and has a small solar panel on top to charge that. It senses when it gets dark and will turn on at dusk.

    I can fit three of the little cells I made inside of the base, out of sight. I can run wires up through the middle to the circuit at the top.

    I used 3/4" copper caps. Magnesium rods from HERE. Alum from HERE.

    You can see from the photos below that it will run off of two of these small cells in series, however it's not as bright as when it's running off of the included AAA battery.

    I'm trying to determine the best way to go about maximizing the potential of this lamp. I could take out the exising circuit and run each of the 3 crystal cells to their own LED on a Bedini Earth Light Circuit. Or I could hook them all in series (or parallel) and run them into an oscillator circuit and tune it (although I'm not too sure on the specs with that).

    Really want to nail down a solid way to make this look nice while maintaining solid functionality. It's great that it's already a lamp type design, which means the wife doesn't have to look at a random copper bowl sitting out with wiring and an LED sticking out of it somewhere haha.

    Was also thinking I can mount a POT right on the base of the lamp for tuning, and drill holes in the sides for venting and easy access to add water to the cells.

    Any suggestions on circuitry or wiring ideas? Thanks for reading.

    Really nice! I will give it a try.
    Cheers!

    Thanks for the tips Billy! I stepped away from this project for a bit, but hopefully will circle back around to it before the end of the year...

Ok your copper bowl is very deep and your magnesium seems to be around2 inches above the bottom of the bowl. Johns magnesium is rounded off on the edges so it can be as close to the sides and bottom of the bowl. A few posts back you mentioned the John says the thinner the crystal layer the better. I think your mags diameter is to large for your bowls. Also your alum seemed to be real chunky try and grinding the crystal into a fine powder.

    Update on my new cell with the holes drilled in. I just put about 7ml of water into it, and let it sit for about 30 min short circuited on the multimeter.

    Pretty decent improvement in performance from the cells without holes. Since I've been typing it's risen to 89.3mA. Again this is after about 30 minutes.

    And here is another video comparing my cell with holes to my cell without holes. With holes does about 12mA better currently (increased surface area).

    Shot a video of how I make my crystal cells. I try to follow closely what John B. does.

    Where I buy my alum: http://www.myspicesage.com/alum-powder-p-531.html

    I had Teslagenx cut my magnesium for me as I didn't feel like messing with it. They did a great job with the drilling and the cut.

    Oh haha, yeah they have a great tone for their price. I got mine I think for $75 on ebay a couple years ago.

    I'm going to order some bobbins, and wind up a new coil... Thank you for the tips!

    go to this vid https://www.youtube.com/watch?v=8xSqL-gc07o at 4:33 you can see the bobbins on the big oscillators on the big crystal lamp

    Hi Tom-

    Are these what you are referring to: http://www.ebay.com/itm/50pcs-of-Sty...item1c3fe479c6

    I don't understand what you mean by you used a pair of presonus mic pres? I have the presonus eureka...are you saying you used some of the components inside one?

    Also, would you recommend sticking with the 40AWG wire?

    I watched the spot on the DVD that you mentioned, and it was right after he made them, I dont think he expected them to stay at that current. wind that wire on a smaller bobbin like one used for a sewing machine for the bottom thread, more turns, bigger field. start with one led, and put a potentiometer in there and tune for brightest point. ... I used to use a pair of those presonus mic pres.... 8 channels they were a good value at the time.

    Ok I built the forced oscillator circuit John B. describes in DVD 29. Used 45ft of 40AWG copper wire to make my coil. You can see in the vid it's lighting up 4 LED's...but not bright enough to be useful.

    In the DVD, John hooks up a single bowl to an array of 5 LED's, and they are VERY bright. How in the hell did he do that haha? I shot some video:



    Only thing I can think of is that maybe these cells put out more power when they are first created, and then once they form and dry out a bit it settles down to around 30mA.

    Just a video update of my progress.



    Copper bowls I bought are here: http://www.ebay.com/itm/LARGE-TRADIT...item461e958a9d

    If John misspoke then I understand that. It's a pretty big error though. The whole reason why I bought these new bowls and discs was because I thought my previous bowls were not putting out the power they should. So I've spent over $100 based on information from the DVD that is false.

    I realize that it's not your fault, and that this stuff isn't scripted and it's all experimental. It might be a good idea to make an edit to the DVD though at that point in the video...maybe some text at the bottom. It might save others some money and time trying to replicate a current that isn't possible.

    You make a good point with the small scale cost of making a DVD...I didn't think about that.

    Regardless...I have some nicer looking cells than my previous iteration, and I know now that they are operating exactly as they should.

I will say this, these vids are done live with no "takes" Tony turns on the camera and JB goes for it! if you have the SG machine DVD you see where he draws the gen circuit its incorrect the first time and then he later on corrects it. not making excuses just letting you know its not this huge multi day production with scripts, etc...

    It is unfair to compare the cost of a DVD from a major movie house where 45 million DVD's are made of a single feature film, and a small run (500 to 100 units) of a single DVD. you being in the music industry know how intense post production and mixing is. its 1 hour per minute for mixdown to a stereo pair of tracks, then add the cost of mastering. you have probably spent hundreds of hours mixing music, just so you can sell a song for 99 cents on ITunes....

    unless there is another alum mixture on the DVD I don't know about, I have NEVER seen a little bowl size crystal cell that is pure alum put out anything close to 500 milliamps. we have built them at multiple conferences and here also, they are always the same. if you want more current you need to parallel them, or make them larger.

    I will watch the DVD and get back to you, if anyone else can please chime in on this.
