How it works (simple) So as we all know, when you switch the power on and off to a coil it creates large spike of electricity (BEMF) that spike is what we need to charge/rejuvenate are batteries.
So that’s what this unit dose.
(1) When the power is supplied to the coil it crates a magnetic field that attracts the small piece of metal in the diagram. Now when the small piece of metal moves towards the coil it disconnects the power to the coil causing the magnetic field to collapse releasing the pull on the small piece of metal allowing it to spring back in to its previous position reconnecting the power to the coil again. Back to (1)

Went out in the shed to day for the first time in weeks and built the unit up.
It works very well but very noisy, it’s probably the best results I have had from any of my work for a longtime.
Works from 2 to 24 volts the output at 6 volt into 12-volt battery was 14.78. It did take some setting up to get it running and at the moment I’ve set it up trying to rejuvenate a old 12 volt drill battery so will let you know how it gets on so far its looking promising.

This is great Daftman. My electronics class [Middle school kids] love it! They are trying to replicate your work. Thank you for sharing your idea. You have them SO MOTIVATED that I am guessing we will have most of them wanting to be an engineer and work in this field. Thank you for motivating our young minds and giving them a person to look up to and want to be like.

and i was sat waiting for the big bang from the capacitor...
I think you should name and shame thos people that emailed you... because they odviously 1) don't know anything about electronics nor mechanics... and 2) are complete yellow bellied cowards not to post here on your thread for everyone to see...
and yes, i was being polite...

TEEP, awesome. What coil configuration do you see as optimal for charging a battery bank with BEMF? Have you used your refurbished batteries after they have been charged with the 'school boy'? Thank you once again, Topher |

This thing ROCKS!!! I have been mainly concentrating on this exact device for the last year (give or take) I will provide some links in another post in this thread, fetching it NOW.
Great work DaftMan, I left some suggestions on your youtube vid, under Electrician725

FIRST ATTEMPT w/RELAY CHARGER **********************************************************************
Time.................Source volts.............Charge volts
Just prior to start...12.7V......................8.7V (Stupid 20V scale, but it DOES NOT ROUND UP so 12.7 is not 12.69, it is a minimum of 12.70V) All readings below are on the 200V scale (4 digits)
(start) 3:15 PM................12.65V...................10.90V 3:30 PM................12.66V...................10.82V 4:30 PM................12.66V...................10.77-10.78V 5:51 PM................12.66-12.67V..........10.74-10.75V 6:56 PM................12.66-12.67V..........10.72-10.73V DISCONNECTED@ 7:11 PM................12.72V...................10.03, rose to 10.05 then stable @ 10.04V So I picked up right at 1.3 volts of charge on the low battery while basically losing nothing on the drive (source) battery. I terminated the test because I did not wish to leave it running overnight just yet, I'm not that familiar with this machine yet but it seems pretty safe... Comments on that or anything else are welcome! I have a separate area so noise is not a problem, but quick access to the IRO is a problem, so I'm unsure about leaving it run overnight at this point... ********************************************************************** NOTES on first run:
I was only getting around a 30V DC spike, so I went and purchased the RS 275-0001 from the video. I was getting no Neon lighting under any condition, so I tested the spike volts by dumping into a 450V DC cap I got from my Dad (thx Pop!) and got under 30V :(
My relay is a 5 terminal 12VDC 40 amp unit from Advance Automotive, but apparently it does not have an iron core or maybe uses a buffer diode... time to check! ********************************************************************** MORE NOTES:
Yep, it had the diode, but was still charging batteries! I got a modded RS275-0001 relay in there now, it's WAY LOUDER and the output voltage is maxing out my 200V scale! I got bright neon glow-age now, none before. I'm charging like a champ now, as well! The old setup had plateaued... **********************************************************************
I had some good results with 6V conventional carbon batteries, no real data recorded but good charging with the old diode-relay. (ditched that thing, got Imhotep's Radio Shack Special!) I am doing all gel cells now, 1:1 charge to drive ratio, then perhaps I'll try a 4:1 charge/drive ratio. I need some good advice on what state of discharge to use, I can vary my drive voltage easy enough, (adding 6V lantern battery in series) but should I use batteries at a 12.5-ish charge level or "dead" batteries? PLEASE HELP!
Also, The RS 275-0001 relay says 14V on the cover, and in my experience, ALL electrical components (mostly AC for me) have a conservative 80% de-rated suggested load or duty cycle, so doing the math IMO 17V would likely be safe for sustained periods at these low current draws... **********************************************************************
I HAVE SINCE ran the Radio Shack relay for sustained periods on 24VDC and it has held up very well! I checked duty cycle on my RS meter, it measures HZ (frequency) and calculates duty cycle as well. Since duty cycle was so low, I decided to kick up the input voltage to 24VDC and the only downside was possibly shorter contact life, I have to clean the contacts more often to remove arcing residue.

I have 4 RS 275-0001 ordered. (My local RS hardly stocks a thing anymore, its really a TV repair shop with the right to sell RS goods.) I intend to work on the Imhotep modification. I just finished and have running Imhotep computer fan mod and using Daftman's school girl control circuit I have charged 3 Nicad D cells from a tired 9 volt. Not much power as the fan has only 70 winds, but it got me started.
So I figure I can use Daftmans circuit as well as this 275-0001 circuit (as I get it working) and now possibly this basic mechanical solution to start testing my coil winding skills. Thanks Daftman also Rob for the info.

Lorke, the RS relays are not the best, however, no one has a good part # for anything else! The 275-0001 needs modded for an NC contact, and the way it is usually done is sub-par and does not last as long. I'm going solid state next, and get rid of "contacts" for good! They burn and stick after a while. You can get a 5 pin automotive relay, but most of those have the diode that needs removed to get a good back spike. I have different styles now and am going to use salvaged contacts on an adjustable model. Just for fun :D

To reduce the damage to the contacts you can source what is called conductive cloth it transfers power with out the arc so this reduces the contact damage. I think it will quiet it down a little.

Thanks Vesperhbt, I will look it up. Electrican, I did hear they would not last long. That is why I ordered 4. :-D This is just to further my personal intro to the subject and knowledge base.
A question though. Electrician, On one of your other posts where you added a coil parallel, was the second coil triggered by the relay too? Might be a silly question, but I am still learning how to read the circuit diagrams.

Both coils are triggered by the same contacts. Resistance will cut in 1/2 with 2 identical coils, which raises current, so series/parallel is good, you can use all 4 coils, 2 sets series connected and those 2 sets parallel connected to restore the original resistance. Or, hand wound coils with longer larger wire for custom resistance levels. 4 ohm/volt seems to work well, but it can go as high as ~8 ohm/volt, as the 12v coils are around 90 ohms. I have used 24 volts on these. 4 to 8 ohms seems to be a workable range, but note this: I doubled the input voltage but only got around 5 to 10% more output, so there needs to be some fine tuning done to get max output. Solid State may be a different story, the higher input voltage may do more because it is not wasted as "spark" at the contacts. Aromaz (youtube) adds spark gaps on oscillator circuits, after the coils. Check that!

Lorke... Good luck and save some cookies for me there my fav. I cant seem to do anything on paper any more just tied into a computer to much I guess.
In a week or so I will be making a test of this unit as well just for fun and something to make noise in the dead of night when I am working in the office

Hello Everyone. I'm about to build my first coil for this mechanical pulsing unit. Can anyone give me specs for the bifilar coil that would be optimal for this configuration? Also, has anyone used magnetite in their coils core? I was wondering if this would help the coils performance.

Bifilar is not needed, you can use single coils. However, I'd try bifilar coils after you get the hang of it! Some interesting things may happen, it's on my to-do list :D

Thank you gentleman. Are there any videos on youtube that you could recommend for coil construction? And have you ever used magnetite in your the core of your coils?
