GK,

I can confirm 150v spikes, however I believe these are normal spikes at the collector of the transistor.  I confirmed this by removing the feedback from the collector coil and the spikes remained the same.

Can you disconnect the collector feedbacks and see if the spikes disappear or remain?

I can also see spikes across the collector coils of 100v, but if I load them with a very small 12v bulb, they go flat and the bulb does not light at all.  There is no power in them.

I have not seen any heating so far.

Hi Dom,

There is not much to tell so far.  I have built a TPU as close to GKs as I can.

I have connected to it a 3 555 timer generator like GK and tuned through, nothing special.

I have tried a Seike oscillator (self fed 3 phase) I have tried white noise and I have tried a logic circuit which provides me with perfectly sync'd harmonics based on the input frequency.

I have attached a 4 channel digital thermometer to measure the TPU temperature in 3 locations and the last probe to measure the room temperature away from the coil.

I have measure the power in the feedback circuit, the 12ohm resistors in Ottos diagram, I have loaded the collectors down with various loads.

So far I have seen nothing I have not already seen.

I dont think I need to list anything further since I am not making any claims, just that I have made an identical TPU with the instructions given and I have seen nothing.

The tripple 555 timer circuit works very well and the PCB was kindly sent to me by Alex (GroundLoop), but its lowest frequency is 3.5Khz and GK has been testing around 10Hz.

So, next I have to connect my 3 independent function generators with some drivers to the TPU and hope that then I can see something nice.



Regards,

Dave.

Dave,

Hi, thanks for the references, I had read them before also.  I did hold a small magnet nearby and could feel it vibrating, but what do you expect when you hold a magnet inside an oscillating field!  Although I cannot say if it was somehow vibrating faster than the applied frequency, how can you tell?  Perhaps wind a coil around the magnet and read out the frequency on a scope?

Well I will either build a 555 timer circuit which has 1-100Hz so its much more fine tuning or I will hook my signal generators x 3 to some transistor drivers and see if I can anything then.

Surely if the transistors are in full saturation have no voltage drop across them, then they could well remain cold while the higher resistance coil gets hot?

I have also built and tested my GK TPU, though I haven't tested it much.

The insulation on the wire I used was crap (It must be an awfully old spool of wire, like ancient, or it must have been heated, I won an internet auction) so there is a short between 2 on the control coil layers.

Because of this I am reducing the testing of it to 'quality time' before it gets any worse.

GK, I seem to recall you mentioning that it reversed the earth magnetic field, now if that's what you said, that would be a great test to try.
Though as the coils are wound on steel with opposing fields I would expect significalt external magnetic fields so are you sure it was indeed reversal of the earth magnetic field?

If it is true reversal you could of course turn the TPU and the compass needle shuldn't budge.

Otherwise please explain exactly what I need to do to see something because I fear it might not last for long. (and with control coil layers shorted together as is it simply may not work.

--giantkiller. You gonna post a picture of your monster before the towns people torch it?

Talk at ya tomorrow.

It's Camera shy, sensitive about it's hair. (I just have the wires going everywhere)

I'll post it soon, but please don't point and laugh.

I greatly applaud GK's success.  But I think the main reason WE as a group haven't achieved success is because we have lost our focus.  If we re-read the 13 PAGE ATTACHED FILE (MS Word format) containing SM's words & admonitions ( and watch his videos), he mentions 3 Control Windings over the Collector Winding to cause a Rotating Magnetic Field.  Remember that he uses the analogy of  a GRADUAL "revving up" (or down) like a turbine.  He says we can SEE IT on a compass placed in the center.  Remember, SM said that modern MICRO CONTROLLERS make things easier.  Hmmmmmmmm, why did he mention Programmable Micro Controllers?  Let's see.

So far, most of us have been focusing on 3 different Frequencies,  BUT, how can 3 frequencies, feeding 3 Control Windings, NOT SYNCHED TOGETHER, cause a Rotating Field.  The answer is they CANNOT.  How can they?  When Freq 1 is rising on the scope, Freq 2 might be falling, & Freq 3 might be at zero.  This is feeding continuously conflicting data to the Coils.  No, this will not do it my friends.  Unless we can rotate the field in synchronization (to Rev it Up), we cannot achieve success.

Plus, why build 3 Levels all at once.  Why not build 1 Collector Coil Level with the 3 Control Windings on it to test our circuit with a compass.  One level, rather than 3 will at least tell us if we are on the right track.  Levels 2 & 3 can be added later after success with Level 1.

The objective is to Fire a Pulse to Coil 1, followed by a Pulse to Coil 2, followed by Pulsing Coil 3, etc, etc, etc, around & around in sync.  How can this be best accomplished?  I know there are many ways, such as Crystal Controlled Oscillators, Phase locked Loop Circuits, & Micro Controllers.  But I can immediately think of 2 ways that would be the easiest using 555 Timers.  There are hundreds of schematics on the web for Oscillators, 1 Shots, & Delay Circuits that use 555 Timers.

METHOD 1:    How about a Circuit that has four 555 Timers fed from at least 12 Volts.  Timer 1 would be the Main Variable Oscillator to adjust the Main Freq.  This Timer could feed 3 other 555 Timers configured as One Shots simultaneously in synchronization.  The three 555 One Shot Delay Pulse Widths would be configured to output 3 different Pulse Widths IN SYNC!!!  This configuration must cause each Coil to be Pulsed SEQUENTIALLY, 1,2,3, around & around & around, in a circle!!!

METHOD 2:   Method two is using a Shift Register.  One 555 Variable Square Wave Oscillator would feed a Shift Register that would sequentially fire Power Transistors that Fire the 3 Coils.



Respectfully Submitted.

From the past messages I see reference to three coils for the COLLECTOR coil but no number on the control coils.  Where are you getting this info?  The pictures of the open unit visually show 4 control coils, (two sets opposing each other?).

About the collector:
It is three separate coils of multi strand copper wire laid one on top of the other, not interleaved. Three is important. You can do many things with three coils. You can run them in parallel, you can run two in series and one in parallel, or etc.
