@Otto,
You have MSpaint. Use it.

.....  About turning the TPU 180?

I was very clever and wanted to see if the TPU would work if I turn it 180?.
What I saw: NOTHING!!!
What happens:
I was pumping the frequencies into the lower and upper control coil (as usual) and on the other end of the coils was +8V. On my power supply I have a ampermeter connected. It showed nothing and so I was looking if there any connection was loosed but nothing. I was looking everywhere but didnt see anything wrong. The function generator was ok, power supply ok but the TPU didnt work. I lost a lot of time but tht TPU wont work. Looked to me as it was blocked. I turned it then again and it worked ok.
About the spinning needle

The needle was not spinning when I had to connect the wires of the TPU and I was wondering why.
The reason was very simple. The needle was not magnetized. I dont know why or how but the needle lost the magnetization and I couldnt it magnetize anymoore. Why??

When I connect a load to the collector coil(s) the output voltage drops a few volts but of course I have not lit any light bulb.

Now I have a question to you: when i short the output of the TPU nothing happens. The voltage drops a little and nothing moore. No heating, the current from the power supply and from the function generator is stable... please answer because Im not the brightest.

Otto, 
are you saying your TPU works only one way but when you turn it upside down it does not work?   I'm confused by your choice of the word NOTHING,  are you saying NOTHING significant happens? or that NOTHING, no output waveform (implying there was one before)

If you've found a phenomenon that depends on direction to the earth its amazing.

Spinning compas:
you're now saying the needle does NOT SPIN,  I thought you said it did? 

About voltage drop:
How high is your voltage?  If its 5 volts and it drops a few volts (lets assume 4.8V) then you are down to 0.2V and you can't light a lightbulb with that.   But if you're voltage is 100V and it drops a few volts , then its interesting.  Are we talking DC voltage here?  If its AC of very high frequency, then the fillament's inductance starts to play a big role and at high frequency the impedance to current is high, so no current flow.   Try using a rectifier bridge and convert it to DC and then try to see if you can draw a significant current.

1. He's saying that his TPU stops working when he flips it upside down.

2. He's saying that he ruined his compass. He's going to buy another one.

3. There's no reason to believe at this point that SM uses a rectifier bridge.

Hi Kosh,

>>>>> Does the effect reverse...>>>>
Don't know. I have never tried to reverse the diodes, don't even know why. Good idea.

@gnostik,
Good call on the bottom line.
