Successful TPU-ECD replication !

[giantkiller]

@schematics request,
Pic controller from futurlec.com to a dac on top of an r2r ladder for a postive offset. This will increase the range of the 12 bit dac. The outputs go to xr-2206s and then on to 27 irf840 fets. The Pic controller will have a PC interface on a laptop using slider and soft switch controls.

It is not what we know, learn or repeat. Genuis is executing attempts against the status quo in the face of denial.

All of the small tests have been tried and shown. Why not build on that to the next step? And never stop.

Looking at oscilloscopes which cost less than $800 US dollars, I see that most of their specifications indicate that they can handle peek input voltages ranging from 250V up to 400V.  It is clear to me that it would take a significant amount of power to fry even a cheap oscilloscope.  Therefore, if someone here has had enough output from their coil to fry an oscilloscope, then the result from their experiment is significant.  Now, to shift from oscilloscopes frying to signal generators frying, I would like to share an experience I had with a signal generator.  On a piece of radio equipment we were working on there were two BNC connectors on the back panel, one was input to the tuner, the other was output from the transceiver.  Someone had accidentally connected the signal generator to the output BNC connector.  What do you think happened to the signal generator?  The fuse connected to its output BNC connector of the signal generator blew, but before it blew, the output voltage and amperage displayed on the signal generator's screen shot way up.  This is similar to what Jdo300 saw when he was experimenting with his coil, look at the first page of this thread, but instead of having a few kilowatts being pumped into the signal generator, it is just pumping a little power into the signal generator, but not enough to fry it.  Some of that power displayed on Jdo300's signal generator may be induced by EM waves from the coils, but in order for that much voltage to be induced, you would need a pretty strong EM field.  In order to reduce errors from induced current, the signal generator should be on the other side of the shield, and maybe even placed in another Faraday cage for even more protection from EM waves.  However, I don't think all of that current being displayed on the signal generator is from induction, I think it is possible that the coils are actually feeding power back into the signal generator.  I would theorize that when the experiment is ran again with the signal generator setup as I mentioned, the voltage and amperage displayed on the signal generator would only be marginally smaller than it was in the original test, but with the voltage still being higher than what the signal generator can output.

@Jdo300

Have you ran your experiment with the signal generator being better shielded?  If not, could you try it to see if my theory is correct?  Thank you.

Did anybody take the bait on the comment of 'Tesla not being concerned with distance'?

That arena is a whole new space of unknowns worth delving into.

Also, the LCD backlight controls operate between 10 and 200 KHz with output voltages up to 5.8 volts with up to 200 mA..
This is well below 2 watts of power.

I don't talk about LED backlight. I refer to the most commonly used CCFL backlight at 3000-4000V output at 50-100KHz just before
the impedance adaptation capacitors.
You can try hooking up your oscilloscope to this output without using a high voltage probe...Pofff.  Oops, the scope went to hell.

@Ergo

Actually, the strike voltage for a CCFL is dependant on the length and diameter of the CCFL.  For a typical CCFL used in the average sized LCD computer monitors, the strike voltage is around 500V and uses around 3 mA, which is still less than 2 watts.  The CCFL inverters used in larger widescreen TVs can output voltages up to 2000V, or more, but this is because the CCFLs are much longer, and tend to have much larger diameters than those found in computer monitors, thus requiring a higher voltage.  An oscilloscope rated to handle a peek of 300V actually can handle voltages almost twice that for short periods of time before frying.  I was a certified computer repair technician at one point in time, and I know a lot about how computers, including how their monitors work.  I don't wish to argue with you anymore, you have your opinions and I have mine.
