Stanley Meyer replication with low input power

hi Gheller J, do you have a link to the circuit diagram that relates to the PCB design you posted. Its different to the Lawton circuit, is this the one where the frequency remains stable when you adjust the mark/space.
Thanks

I do not know if someone else did it, but I was the one who put up the revised circuit to keep frequency stable while adjusting mark/space, unfortunatly it had an error which has now been fixed...


I had omitted R7 and R8 but now they are included, the discharge pin 7 of the 555 timers need to go to the junctions of R7-VR4 and R8-VR2

I am sorry to everyone who followed my original circuit, the error had not become apparant until the circuit was mentioned again, the above cicuit is now correct.
If your concerned about the 50k pots instead of the 47k shown in the original circuits do not worry, either 47k or 50k will work with little difference.

thanks Runningbare do the ends of variable resistors that are floating go to the sliders?

[RunningBare]

No, VR2 and VR4 will function as is, the floating ends can be left floating(disconnected)

JUST RECEIVED THIS FROM A VERY VERY RELIABLE SOURCE !!

i'm sorry but if you are using the lawton circuit alone this will not do anything but limit current, the back emf is wasted, if you are going to use this whith out a use of a transformer you should use this circuit, therfor it does not wast the back emf as the first picture, if you was to use the first picture you pasted it would work fine with a transformer, but the second added diode is not doing anything, and the direction of the chokes must be hooked the right way.

using the same core means sharing a magnetic field, if hooked improperly you loose. the core inside the choke takes on a discharge effect, when sharing cores the discharge emf effect falls faster, it is better to use single cores so each chokes can fall at it's on electro magnetic field rate.

it is very important that the 3rd cycle of the transformer hits the chokes at a discharge level, if the transformer hits the chokes on the 3rd cycle and they have already been dishcharged caused by using the same core, then you loose again.
