Super Simple way to understand the TPU

[innovation_station]

im not gonna have to make 1 more real simple video explaining this agin am i??

this works as explained

use a transformer  a spark gap and a light bulb

then you tell me it dont work

i mesured amparage yesterday 

how much did i mesure on my real cheep meter ??

not 20 amp from a 15 vdc 1 amp supply

ist

of course this was a peek and it was not run constant

enjoy

as near as i can tell it only works when it is hooked up 1 way

be sure to take that into consideration....

this device teters on the operation of the IST REZAP POWER PAC!

when i get to it i will be building this too...

This is unbelievable... Piece of iron (3kg physicall training fillet) I have acoustically rings at 7 HZ! This is f**cking absolutely unbelievable.

I have a proof - just recorded it with a high grade mic I have.

This seems to be absolutely impossible, because it simply does not have required size for such low frequency resonance.

Another sustained frequency is 2.186 kHz, but it may be related to physical size.

At attack stage frequencies like 11.4kHz, 5.475kHz, 6.900kHz available.

EDIT: sorry, it is closer to 8.5 Hz, but still is very unexpectable.

EDIT2: Well, I was too quick with my results... That 8.5 Hz is probably coming from floor, but still it's remarkable how this piece of iron resonates to such low frequency - I'm capturing the sound directionally, it's not just surrounding residue. I'm doing more tests in suspended state. Will post more plots.

Further test indeed show that some acoustic capacitance is present at around 7 Hz. The plot below is a low-passed audio signal of a single strike (linear-phase filter with 90 dB rejection above 160 Hz). I have used a small iron bar (3.5"x1/10") when striking that 3kg fillet - this time it was suspended by hand over the floor (not optimal as well). Well, this may tell little as good acoustic measurements can only be done in an anechoic chamber utilizing highest grade transducer and microphone. But still, such simple "impulse response" test usually tells much. If there were no such 7 Hz bump, the iron would not run into the resonance with building's flooring.
