QuoteCould this aspect of electrical physics
be related to the "Tesla Hairpin"

Seems that it would have to be. Quite sure Sweet studied Teslas work.
Has anyone taken a clamp meter and put it on these Wires? A normal incandescent 100 watt bulb is drawing about .8 amps.

267.4mA is pretty darn good, and 24 hours is great. How noisy is the smaller version of the imhotep charger?
Also today, I used the reed switch which is part of the radio shack reed relay. ]

do you remember if that reed switch was the 12 volt one or the 5 volt one.

my small version makes some noise but if i keep it hanging in the air it's not bad at all. i use the model 275-240 5vdc/1a micro relay from radio shack. that and 1 diode is all that is needed to make a real nice high voltage pulser. that will charge batteries plus it will run off a small solar cell.

by accident i just found something interesting. when i short the 5 and 6 the voltage gos down and not shorted the voltage slowly go's back up. but if i check the coil for shorts using the 200 scale and then switch to checking volts the voltage is about double the normal voltage and slowly go's back down to normal. and i am testing with a new meter i brought home from work.

also i am going to be contacting the local recyclers to find out if i can get iron wire from them. in long lengths. right now they only supply me with 22 foot lengths which is why my coil is small.

Yes, it is the 5v reed relay 275-232. I was only using the reed part and left the coil untouched when I was testing.

And where is the diode?

I don't understand.
Where are the probes connected when the voltage goes down?

Well, maybe I do understand...

I just tried doing what you are mentioning and I stuck the reed switch across the 10's so one each inner cu and fe wires (for the newcomers)
Then I shorted the 5,6 (outer cu and fe wires).
I put one dmm probe on the shorted 5,6 and one probe on the Fe 10 side of the reed switch.
Then I moved a magnet near to it.
It makes sense, the voltage went down as the magnet got near and closed the switch making it all one wire with a small amount of resistance.
When I moved the magnet away it restored to the 161mv it started at.

This means the reed switch will indeed work. This is coil #9 which has a secondary. When I can make a rotor for the magnets, this will work as it should.
(Oh thank you lasersaber!!)

I hope they can. That would be cool to get recycled wire.

Did you get some of that wire from wire.co.uk?
Do you need that link again?

In the joule thief, the pos of the battery is connected to the twisted wires that are the beginning of one and the end of the other (Cu 5 + Fe 10).
But this is its own battery so the pos  charge is not coming into the joined wires from an outside source, and which way the electricity flows is dependent on which wires are connected.
however,
The secondary should do the same thing as any secondary if the change is fast enough.
My scope on the same connections showed nothing at all. Maybe because it is hard to hold it precisely, but I saw nothing at all.

I doubt my simple motor will be here as soon as tomorrow, so I will need to be patient over the weekend!!
I could try the roller skate wheel I was preparing for the bedini motor...

The video was having a halogen lamp used.  Radio Shack sells both 120V and 12V models.  They may power hogs in terms of current?  I'm not sure.  A clamp meter would say something about power generated, though, I agree.

i did more testing today and here is what was making my voltage double. it seems that my digital meters when testing ohm's on the 200 scale add +3.00 volts to what i am testing. but the meters only add voltage on the 200 scale. using 2 meters i connect to the 5 and 6 wires and test for volts on 1 meter and ohm's on the other meter. i can then read 2 plus volts. then disconnect the ohm meter and the voltage will go down slowly. so the meter is what is raising my voltage. shoot i thought i found something new.

the iron wire in my coil came from the recyclers. but it is new wire not used ever. they supply me with 22 foot lengths. they are used to make bales of used paper that weight about 500 lbs or more. 

i will draw the circuit and up load it tomarrow for the relay pulser. it is so easy to build. it does not have a neon because it will not light because of the low voltage used. I do know that i can light a 110 volt led night light (not bright) with it but i will light. also i will try and light a string of led's and let you know if that works
