Selfrunning cold electricity circuit from Dr.Stiffler

Doc,  I was talking about measuring the INPUT power,  as in V x I.  Stefan asked the same question.

So, are you still using your input power filter board, the one you showed in the videos?    (I think you showed operation from 24 Volts, and then you showed  a series of resistors , for 1 ohm equivalent,  so what's the voltage across these?)


But,   if you want to measure the power OUTPUT of the motor,  just take a simple reading of DC volts at the motor terminals, while fed by RF (ignore the RF ripple),  and also measure it's RPM (you can get away with just the RPM, so maybe forget about the voltage if it's a messy waveform).     Then you can do a comparative analysis on the motor, and feed it with DC from a variable voltage supply, and set the voltage to what you had before and see if the RPM is the same,  it should be pretty close.  If not just make sure the RPMs are the same and the motor is positioned the same, so then we can assume the power disipation is equivalent.   Then just measure the current and voltage and you have your power output to the motor.

Damn, the RPM measurement, that is to simple, I did not even consider that.

Well I guess the fellows will need a way to measure RPM.

Hey group, how many can do this?

If the four of us here on OU can do it, maybe some one will take note?? Then we can check the Heat out.

A crude way of measuring the RPM would be to record the noisespectrum/tone from the motor when running it.
Play it back, and tune the voltage to reach the same noisespectrum/tone.

Easyer than creating a light/laser/magnetic/switch based RPM measurer.
Just a quick idea to get a fairly accurate reading. Probably woulden't hold up in court, though 

A headset mice and Windows "Sound Recorder" would do, I think.

This is the PITTS!

Here is the coil info I promised, but I had to put the pictures on MY site, take MY TIME to do an htm page to display then. This is silly.........

Anyway all, the coil info is at www.drstiffler.com/coils.htm

@Plengo
I left you a comment on YouTube, the right coil should help.

The frustration with the pictures could be reduced by about 100% if they were saved optimally in the first place.  The pics referenced above are bigger than they need to be by a magnitude of 10.  Displaying a 300k gif file that should be a 30k jpg is a waste of resoures (space, bandwidth, download time) no matter whose server they are on.  As a general rule, photographs should always be saved as jpgs because this compression algorithm is optimal for the many colours and subtle gradiations of "real life'.  Diagrams, logos and other images with large blocks of solid colour on the other hand benefit greatly from gif compression. You can always tell when a file that should have been saved as a gif has been saved as a jpeg by the jpeg artifacts and fuzzy, poorly defined edges.  A good example you all might be familiar with is the main page of Free Energy News - that header should be a gif and as a result is less attractive than it could be and much larger than it needs to be.

Hope this helps. Several examples of properly compressed images of good quality and under the 50K required for this site can be found on the "Lenz Thane a Hand" thread just next door.

@All
I have some ideas in this department but I will have test them out first. All I will say at this point is "just imagine"! Photo interrupter, or break beam, small neo and hall sensor, two small neo's and two hall sensors, two small neo's and some windings,  . Nothing definitive yet but I will find something for RPM measurement. One thing to definitely consider is we all have different motors and slightly different flavors of the SEC. Dr. Stiffler, as well as I, will likely want us to come to some consensus on the test rigs for consistency and ease of comparative study. Just thinking out loud.  Got to get back to the shop! Damn!

Best regards,
