TPU: End Game...

[Thaelin]

Hi all and the question by IST:
   Tubes? Well the darn things switch extremely fast. Now when they were playing with solid state, the transistors were very slow. We do have mosfets with gate drivers that will get to that speed. A tube is just the easy way to make it happen without worrying about all the noise and harmonics it generates. A bit of care must go into the design of the switching circuits. That comes right from Mannix. Hence why he kept asking if anyone knew what the difference between tubes and ss was. Took me a while to get there. I grew up with tubes and should have known it from the get go. Didn't catch on very quick tho.
   As for the build, well that is where I have seen all the strange things happen. No better thing than to see it right on the scope screen in front of you. Lots of dead horses in the box. A bunch that made it to the compacter as well. But, getting there and having a ball doing it.

And on a side note: Gnosis made a ref to magnetometers and so off I went to see if I could gleen just what tesla meant by "tuning" one to the storm. Well, seems the freq the coils were set to was 32.5k and thats real close to the core freq of the 15" tpu. I would be uuber careful if you play with this one. Its the direct "center" frequency of lightning strikes if my guess is right. Tune slightly off center of it...... All starting to get solid.

Gotta find a switch that has an on time of 1 nano second?  That seems pretty unrealistic, but I'm not an expert on trasistors, mosfets, and tubes either.  Is there a device that can switch that flipping fast?

Here's a Hint. And Pay attention to the last item on the list especially... This is where I'm looking now..... toroids toroids toroids...

Take a look at the MG400Q1US41, datasheet attached. A bit large, but they should have similar lower power devices in smaller packages. I have not looked.

Rise Time (tr) 0.3 uS typ, 0.6 uS max
Turn-on Time 0.4 uS typ, 0.8 uS max
Fall Time 0.2 uS typ, 0.5 uS max
Turn-off Time 0.8 uS typ, 1.5 uS max

hello all here is 1 more important thought i had

and this was a quote from sauron some time ago he said that the winner will not be cold so what do you think that means also get it hot with a lot of noise what does that mean ?


here was my thought how do we cancel the magnetic flux well i know of a ring in france that cancles the flux by cold at -270 deg c. or around there so i think that is cold flux cancelation

ok with the tpu maybe it only cancles the flux after it gets hot also we can not cool it by fans so it makes me wonder also in 1 of the videos i think it looked like he got burned not shocked could that be how it works with heat he also says that he could harness some of the heat to make even more output

when i think of heat i think of crystals

hummm   ----------------- just thought i would share that thought


the ring in france is 37km big herd of this on the radio
