Many thanks to user Turbo, who did the compilation.

Well, I just received this mail and he might be right,
so be cautious if you experiment with the TPU.

Better try first no feedback loop and try just to measure output
versus input power!
But don?t yet feedback anything
before you are not exactly sure, what you are doing and
make sure, if you use a feedback loop,  there will be safety measuresin place,
like fuses or overvoltage protections
that can prevent an explosion.

Think about how likely it would be to stand with a microphone
in feedback with a 100 KWatts loudspeaker power amplifier 50cm  in front
of an AC/DC band stacked Marshall loudspeaker towers and getting a VERY LOUD
feedback from the microphone and having no ear protection on...

Also never touch an wires from the TPU, always work with gloves and
remember, if you touch a high voltage containing capacitor, yoi can be
dead immediately !
Already 300 Volts DC at 1 uF or less can kill you, if it will
go via your heart !

So here is the message I received:

"Heya Stefan.

Do you think it would be a good idea to sticky and lock a safety warning in the 'Steven Marks TPU Devices' section?

The research going on there has always been dangerous, and with more and more people getting involved and starting to get results, the chances of someone having an accident are only increasing.

Safety is an issue that's often mentioned in the threads, but perhaps a more formal notice is warranted.

Such a warning wouldn't be intended to stifle experimentation, but to just remind people to be careful and perhaps keep the less competent from messing with something they shouldn't.  Of course accidents may still happen, but then again, maybe some can be prevented too if a message is there encouraging people to take care.

Whether such a warning would be written entirely by yourself or in conjunction with some of the more experienced participants I don't know.

Just thought I'd mention it. "

Here is attached a new compilation of the recent work of user
Otto and Roberto, what they have achieved !

Many thanks for this very helpful PDF file !
