Testing the TK Tar Baby

[Magluvin]

Got a couple IRF1010e today from an old UPS board. They look like they will work as good as the IRFZ44.

In the original guys vid, his Tx loop looked like maybe some 3/4 in. pipe.  lol.  Seems like he is getting some good distance also.

Nice job of circuit redraw. ;]

Thanks T

Thanks.... look familiar, does it?

C1-C8     High quality polypropylene totalling about 60 nf, 400 V or better (they get hot and lesser caps will melt down and fail)
C9          100nF poly 100 V
D1, D2    1n914 or 1n4148 or similar
L1, L2      Radio Shack 100 microHenry, a dollar forty nine each
R1, R2     Gate pulldowns, 10K 1/4 W
R3, R4     Gate bias, 100R, 1Watt
Q1, Q2     IRFZ44N on heatsinks (important)
Transmitting loop # 12 house wiring, STRETCHED to straighten ( a trick I'll give you for free) and then doubled and twisted with an electric drill, trimmed to 22 1/2 inches and terminated with 12-10 ring connectors, soldered

Receiving cap should be of the same capacitance as the total in the tx, but it only needs to be single and 200 V or 300 V is ok... but watch the temp on long runs. I've blown 2 rx caps but no tx caps.

Let me know how your misfoots work out. I've got an order of Z44s coming from Singapore.

The first one is neater I think, but the second one is smaller and I used a prefab pad-per-hole circuit board that is laid out just like a breadboard, cost about 3 dollars, and I used about half of it. Some copper strips to reinforce the drain lines to the loop. The whole source-drain-cap circuit should be as heavy as you can manage, it will be carrying many amperes of current from the reactive power just looping around, leaking a little out as heat in the caps and mossfeet as it does so.

I made a pipe loop out of hardware store 1/2 copper 45 degree elbows, like a stop sign octagon shape, and the twisted wire I never expected to work well, it was just for testing... until I saw how well it DID work. I may yet try the pipe loop. Have you priced plumber's solder lately ? I can't believe it, thirty dollars a pound or more... which is why I haven't tried the pipe loop yet!

You know Ainslie thinks I'm faking this whole thing, don't you......   I mean... how dat zipon knowhow liteumup dat lite anyhow? Ain got no worrs, no resisticators, ain even got no magent or core. An run da motor.... no way haole, you ono-ono, smoke da kine pakololo bit much potboy.

Familiar? Yes, thats Rosemary's baby. ;]

Auto parts stores have copper oil line kits with a few feet of copper tube already bent into a coil of loops. It can be cut and with a little shaping you can have near perfect loops without a bending tool to keep it from kinking.

It not big pipe, but it makes nice loops.  ;]

Thanks again.

Hey, .99.... and gmeast too... do you now see why I considered the best way to refer to the function generator's output leads as RED and BLACK.... since that's what her cliplead patchcord has on its ends? There is no PROBE, no TERMINAL. There are two identical alligator clips, one with a black rubber sheath on it and the other with a red rubber sheath on it. The red one's wire disappears into the RG58-U cable, as does the black one's wire. Only a more sophisticated instrument user than Ainslie understands that the Black wire is the cable's outer shield or sheath of braided and tinned copper and ultimately connects to the FG's chassis ground (sometimes selectable by a switch) and ultimately to the Earth through the line cord ground wire. And that the RED wire connects to the output of the function generator's electronics, the poynt of the big triangle. Equivalent to the Pin 3 output of a 555, only much more sophisticated... and that can swing both ways, unlike a 555's only positive output.
But the Red and the Black leads are always connected visibly in the photos and it should be easy for everybody to picture these. The use of the symbols + and - on the FG's symbol in the original schematic is hugely misleading as you all can probably understand by now ....well, most of you anyway. I mean, from gmeast's comment it seems that he's not even clear that they are referring to a FG instead of an oscilloscope when they say "probe" and "terminal" in the present discussion.
And... not all FGs have the BLACK lead always connected to the chassis and earth ground. But when it is connected to a fixed reference point like the negative pole of a 72 volt battery, THAT becomes the ground reference about which all other voltages are RELATIVE, positive or negative. So the RED clip's output is positive, or negative, relative to the Black clip's output.. or rather, REFERENCE.

A couple of other points. First, one of my YT commenters, flapjackbatter, has pointed out an elegant solution to the inverted 555 timer issue in the Quantum circuit... that actually  has relevance to this discussion and is one I hadn't thought of, it's so obvious.
If the 555 power supply floats wrt the mosfet power section.... one can just hook the 555's Pin 1 _ground reference_ to the mosfet gate rheostat and the Pin 3 "output" to the power section's negative or ground, the mosfet source. Facepalm. Then the exact circuit values used in the Quantum schematic work to make the exact CORRECT short ON time duty cycle. Double facepalm: two wrongs could have made a right, which turned out to be wrong anyway.

And finally.... she is still getting things confused and putting words into people's mouths they didn't say. I think it's a hoot that she uses my diagram but complains that the colors are too simplistic... then gets confused all over because of the terminology in the very next posts.

But in THIS post reproduced below she says that which I never said. The FG has a SIGNAL and a GROUND, I have said that, and generally if the switch in back isn't flipped to isolate the chassis, it's true. I have never called the pair COMMON and GROUND... the GROUND IS the common, silly. SIGNAL and COMMON is also sometimes used, but nobody... except Ainslie... has ever said COMMON AND GROUND as the names for the pair... and she attributes it to me.
A lie, in plain words, since I am calling them RED, and BLACK, anyway.

RED, and BLACK. That is what they ALWAYS are, for Ainslie, unless... she... did... use... a...(maybe even attenuated)....oscilloscope probe.... as the FG output wire at some point, since they both have the BNC connector on the instrument end.

And it is amazing what one learns, slumming.

Look at this: an actual admission of a deliberate intent to deceive, a collusive plot actually, foiled only by .99's illconsidered analysis and publishing of the correct schematic. And her arrogance allows her to openly admit it, thinking that it's not a terribly wrong thing to have planned and done.

I am truly flabbergasted, giant pickle and all. Kind of makes you wonder what Ainslie's Dictionary defines as "open source".

Pseudoscientific misconduct applies to this Ainslie work a lot more than does "open source".
