Testing the TK Tar Baby

[TinselKoala]

Thats similar to what the Japanese said about genetically modified foods, except they finished off the sentence.
We shall see what the American children are like in 10 years.

For me, 10 years isnt long enough for that sort of testing. If it were up to me, there wouldnt be such a thing to test.

I agree with you on that one. If anything can qualify as a "science blunder" that could wipe us out as a species, GM food and other organisms is right up there with nuclear power and atomic warfare.


Meanwhile, some demonstration of the Supernova Mode (on a nearly dead battery) and some current numbers, from unit s/n 001, the first one that will be released into the wild, as soon as it's finished tuning and burning in.

Thats interesting that you have it in an aluminum briefcase atop you head. Interesting. lol I didnt see it before you told me. You forgot the sign, "Sorry about the light" I should be used to it by now. lol Im waiting for the vid that you say it, and the light is so blazing that the vid would just white out.

But really, these IRF1010e came with  3/4x3/4x2 in aluminum block heat sinks. So my question was going to be, would they interfere with the coil operation?  Was already thinking to have the loop outward from the plain of the circuit board, instead of, say, in the line of fire. Probably any proximity has some affect. 



In the briefcase, does the freq alter any? Does it alter the working distance?

Soon I will be able to answer my questions. ;]

TK,

At least YOU had some hair back there to light up.

Are you sure all that RF isn't stimulating your recent Zen posts?

My daddy died at age 84 and still had a full head of curly greywhite hair. I'm receding at the temples a little and have plenty of salt in my peppa... but I don't have the typical male pattern baldness. Low testosterone, I guess... but it's certainly been high enough, otherwise.

I don't know what came over  me, there. It probably isn't really a good idea to do that. There is after all something like 20 Watts radiated power at 750 kHz or so passing through my brain. Without attenuation too, which of course proves that there is only the purest emptiness within, as Zen recommends.

On the other hand, maybe a low power system wrapped around the mattress periphery could keep you warm without an electric blanket, just some woven conductive threads in the fabric itself.

And guys, and with regard to TK's thread still being available for view - I'm personally very sorry to see this.  The more so as he's now assuming to give a dissertation on QED when he's entirely under qualified and is yet again misrepresenting the rather noble art of science and the hard work that our Greats have managed.  But what's new? 

YOU, of all people, are hardly qualified to judge the qualifications of others.  You are just now beginning to glimpse what all others who are skilled in the art immediately recognized regarding how your circuit operates.

That glimpse, is just that, a glimpse.  Many people know things you don't, and rather than learn from them, you argue and ridicule them.  I suggest you learn to learn, not argue.

The capacitance you question is fully documented in the IRFPG50 data sheet.  The total capacitance as well as the reactance of that capacitance at your oscillation frequency can be easily calculated.  That reactance in your circuit and at your oscillation frequency is typically less than the resistance of Rload.  A robust path indeed.

I thought that case was aluminum; I have a fullsize one that is, just like it, but it turns out that this one's sides are some heavy-duty plastic, stamped to look like the aluminum they use on the bigger ones. There is an aluminum frame but the sides themselves are plastic. It does transmit through thin metal sheets, though.

In the cased version I have mounted the loop horizontally and this puts the heatsinks and Qs right inside the active zone of the loop. It doesn't seem to affect anything, the circuit performs the same and heats the components the same. I think it really needs a pretty close match in order to transfer power and anything that's not a RLC match is effectively transparent to the power.

You absolutely do need heatsinks; and don't even think about operating without the loop attached: the circuit will turn on one mosfet, see a direct short, and fry that mosfet in an eyeblink. I recommend, and have installed, a 7 1/2 amp inline fuse from the supply to the board. No, I haven't actually blown any mosfets with this design, but I did get some of the silicone HS compound so hot it vaporised from the heat pulse.

The freq and range depend on a lot of things; I will do a video with scopeshots, similar to the one I just uploaded with the DMM ammeter. Be patient please, there's a lot to do this evening.
