R.I.P. Lee Crock

Yes, just one wire.

You should maybe check the continuity of your box spring. Check the resistance from side to side. They don't make box springs like they did back then. Most of the mattresses made these days use materials to help reduce the noise and that may insulate them from one another.

Thank you @mrmag

I did not see this one.

I have done some reading and decided to build the device.

What I found vague was the reason of the amount of batteries and the type. Is this so the battery can cause more charge to accumulate on the sheet? And would Li-ion batteries work as good?

A PM reminded me to post a follow up on this.

I have built the device around the previous October. I built this mainly for my mother who has all kinds of aches. The device specs are:

-12x 1.5V D-cell. Made 4 groups, each with 3 batteries hooked in series. So the operating voltage is around 4.5V
-Arduino to pulse a latching DPDT relay every 15min.
-3 layers of standard kitchen aluminum foil under mattress.
-Mattress is quite thick, estimated at 25cm in relaxed state (I'll update this with more specific numbers)

First month or so it had been used every night. Now it's just a few times a week.

The verdict is that the pain and aches haven't really gone away which is disappointing. However I still have the benefit of the doubt. As mentioned the mattress is quite thick. So I was planning on either getting some fine copper mesh or plastic coated aluminum foil for flexibility and toughness. and putting it under the bed sheet as close to the body as possible.

@Broli,
I have built several versions all based on the "Lee Crock" design. The 4.5volt version may prove to strong! also 25cm is quite a distance so could make a difference. I find a screen under the sheet works best but can get creased up very easily. Presently we have one of those foam memory pads over the screen which is about 2" thick, it's difficult to say how much difference it makes to the field if any!! My wife and I are both in our sixties and to notice a benefit takes time so experimenting with various versions is not that easy to draw conclusions as to which version works best. I have two switching times on all mine now ..
15 mins and 3 mins.   These are my findings to date using this device... certainly more energy and less general aches and pains. I have had no back pains since using it. It does keep you regular!! My Wife's heavy legs syndrome and arthritic problems seem to have generally gone away. The secret is to use it for a period until you feel benefit and then disconnect it for a while. It works for me.  I generally feel more youthful especially when rising first thing. I'm still experimenting, note: you may find yourself having bad dreams!!! otherwise no side effects as I can see. Kind Regards

I'm not so sure why so many cells? unless it's related to the impedance!  I did try "AA" batteries instead on one design, but didn't leave it on test for long enough.
The other thought was... Lee Crock's original design appeared to use copper battery connector plates from one of his photographs showing the opened wooden lid. The copper plates would be of sufficient area to contact all the cells paralleled plus ends, and likewise of similar dimensions for the negatives. Do the plates therefore have any relevance on how it works? I'll leave this open for further thoughts. I think results will vary between individuals and younger experimenters may notice results much sooner. Experiences are very common in comparing my own trials to those who have either built their own or purchased one... it would seem. The point being, it doesn't cost much to build in it's simplest form.  The "D" cells are very cheap, and I did build a replica using a battery powered clock module using a change over micro switch and a four segment cam disc. For all other versions  I use pic micro controllers to give me both versatility and precise time periods. My present design outputs directly from one of the controller ports, this one is yet to be trialed.

I too received a PM about the 'energy cleaner' Broli, from a new poster...likely the same one.

Lee made it a point to say that no more that 3 sets of 3 batteries be used...he said it would be too much for the body.

I tried the plastic foil...the plastic was tough, but the foil cracked and failed to conduct properly.

I just pull an alum screen over me at night...according to Lee, the field extended 10 inches on either side of the screen.

If anyone wants to acquire Lee's automatic switching circuit, just send me a PM.

I will never be without the energy cleaner.

Regards...
