And solves you sie...die problems?

No, I want to the students, Relay testing  not the joy of an own success experience take: mrgreen: seriously, it's basically not my task to remove their thinking / paperwork to any students. There are questions in which you realize that the task simply was not understood. In such a case, I'm at least willing to give support in the form of suggestions on how you might tackle a problem (assuming of course, that I am to do this even in the position). There are also questions, where you realize that / the student Pan-ready want to have resolved simply everything to save the own thinking and writing effort. We must forget this very quickly because my spare time as a working family man is probably scarcer than a pupil or a student, and I think that everyone himself should be his commitment to his education. You can also do this for the future world of work. Apart from that I would feel somewhat used me in such a situation. But that's enough the spinner from the Esotherikbereich so go peddle
But just Oxyhydrogen. There are so certain sayings of all in glass houses sit and dig hole. Today, we take a less family time. Who other leg wants to comply with the asshole if it he remains himself dry
So the point about immediately got to want and fast result transferring experiments.
Because we cut us all in own meat.
We take our Royer Oszillilator we build even though be clear to those who have some idea should "scrap" and there is much better circuit even under the resonant converter.
And in the end are the experiments here even after the slogan it should be fast after establishing what visible.
Let's see HV > lightning and shining glass comes up then if ansteurn of a laser which also only visible light and heat are.
I haven't seen yet synthesizing organic molecules with HV experiments.
As small children, we find the great what a faster result brings da keienr takes out of us.
Also after a quick experiment but no desire on the subject is I would say applies to all.
In me wars for example ;-) showed magic box wusstde as I works made it no fun.
And the expensive box of Ravensburger moulder is out until he flew into the recycling bin
At the Rum running because the components I think also we hobbyists themselves off are to blame.
View old circuits on something so magazines such as Elektor and Funkamatheur enbelangt.
Previously small signal transistors in the circuit diagram 3-4verschiedene limited by and large they came out even with 2 variations.
And then our circuits look at now alone if we look around we come loose 20 different MOSFET and IGBTs designed 5 only for the Royeroszillator.
That overwhelmed newcomers and discourages is but understandable.
And then we read the current job times out (is not only with us so).
Constantly that rumgeflenne "why would you do that yourself building is much cheaper when finished buying it, etc".
While I agree with you that there is a problem in the field of DIY.
But I think also to easy to tell that they just don't want what to do.
I think there a lot of additional factors play a role.
For one, the society has become again very Intollerant.
When you see who today feels all professions for others to decide what they must build themselves, and is what the professionals (self-appointed guardians are the pros of course ;-)).
When I think of how many times I heard is not and is not.
I had job wise really a hate when someone the word amateur took in the mouth.
The price and acceptance of "Products" play a role.
Man earlier much easier things building could be that in the circle of giving and could sell.
And attention and recognition is ultimately us, yes a very strong leg River healer.
But this may have the people not with simple things fun I would not want to geralisieren.
If you look on YouTube there is material put also powerful what are really the simplest experiments.
DIY motor from the battery clip and a penny
Or the hype surrounding the Cola bottles and effervescent tablet.
As you can see, it is already possible only, it is very difficult to reach the people.
Ultimately if you would terminals behind it how could you achieve something but since anybody has remain shut it ist(Mist)

I mean just about power supplies

If I have my caps I will SCADA commissioning  out times that in any case, I still have a few power supplies.
The advantage is that hardly any performance at the current limit is lost.
Or just the projector bulb
What do you mean power that is lost... We're talking about a period of time from 10-20s of all maximum where the charging process takes place, the largest part of the "excess" power is passé after 5 s
Unfortunately there is still lots of new things; the University is just. Word then clearly better off starting in October. But but occasionally something will be made, and I'm not really into krokoverkabelte mains voltage (tweaks to the arm!), the mini power charger had to be packed time.

What emerged, is a true lesson of standard-compliant housing architecture. Since it is my first, this statement is probably rather somewhat ironic :) Practice makes the master, one can at least hope.

What I've learned at least:

-Make better only slightly longer cable
-Too thick switch need plenty of space with thick Flacken plugs
-As fast as it comes, comes from a drill rig.
-Beware when ordering and get no MONSTER Cable glands

Well, as I said, the first case, and I find nice anyway the part.

Strange high-voltage remote effect

I still on the twin tower Relay testing  tinkering around: to supply the part with the correct voltage, something had to be fiddled. With approximately 16 kV that fits well, energy source is a 12V lead acid battery.
To determine the minimum distance of the spark gaps, I tested :), the stuff on the "keyboard drawer", so the part where the keyboard resides and is extendable. Here a picture of the building:
The transformer is supplied with the "standard - ZVS', but irfp260n. Idle, takes little power the circuit, also not very much burdened with approximately 4A.
But the real question:
This "keyboard drawer" runs on a rail. And I throw the ZT with the ZVS, there is spark discharge between the guide rails, although nowhere is a conductive connection between the Earth and the structure. Make this track a capacity which must compensate by induction loads?
Would glad if someone told you that.
Could be that the aperture sends out radio waves and catch the iron Rails then the power off, aka Tesla's basic idea.
My first ZVS with 135Watt was to compete with the multi meters by 5 meters without any antenna alone the emits hung vertically (!)
If you think the wooden plate where the building on it, which can go quite through the wood, because wood contains a residual moisture, even if it seems dry fart.
Put on but time somewhere else the whole, as a control test.
The underground is probably cheaper chipboard cardboard, which is not well insulated. But that doesn't explain why there are sparks between the metal rails of this document and those that are attached to the table.
