I'm recreating the Free Electron Pump 1.0 by Jean Louis Naudin for a school project but i have little experience and knowledge about electrical circuitry.
But i got some help from my sis who studied electrical engineering for 2 years (but she's no guru either).
I just wanted to clarify as to what is the actual resistance of the resistors in this diagram. Ohm or Kilo-Ohm?

http://jnaudin.free.fr/html/fep01.htm (the actual page)
And can i use a step up transformer at 1380 V pulses (according to my sis) for the FEP generator. Please do not mind my sheer lack of insight in this area and help me out.
It is common practice in electronic diagrams to omit the unit, when the value of the component has to be read as basic unit.
So all the values of the resistors without a unit should be read as "ohm".

Thanx a lot for clearing that for me.
I do have another question, and that is with regard to the FEP transformer.
I want to purcharse a ready made HF transformer, but again, i'm pretty new to this electrical stuff besides some basic electrical experiments in school. *embarrassing*
My sister says its a step-up transformer. But ermm, once again i'm pretty unsure abt the specifications. I need to be sure of what i exactly need before going to the far-away electrical shop to get the stuff. Once again, please forgive my sheer lack of intelligence in this topic and thanks again!
I'am not sure, but if you want to supply your circuit with 12 volts instead of 230/110 volts, you may look for a mobile neon-bulb like this (http://www.light-and-sound-elektronik.de/assets/s2dmain.html?http://www.light-and-sound-elektronik.de/discoeffekte/schwarzlicht/schwarzlichtlampen/12voltneonleuchte.html) or so.
I think this light must have any kind of high voltage tranformer. @all: If I am wrong, please let me know please.
You find it maybe for a few bucks [put in your local currency] at low-budget or 2nd hand stores.
I'am looking also for a cheap high-voltage transformer this days and this kind of mobile light is my target. Unfortunately my search was still not successfull.

Hi Lazybum,
today I found a good high voltage transformer for my purposes. (see picture)
I found a "magic flash ball" (dont know the right english description for it) at a low budget store ("bargain-store"? german: "Restpostenmarkt").
I got this thing without warranty for 3 euro :-) and inside the case there is a high voltage transformer and a sqare wave generator.
Maybe it is exact what you need!
Bye Markus
edit: By the way: I got also a well running stroboscope-flasher for 1 Euro in this store. Including a 10 Watt Xenon-flash bulb, high-voltage diodes, a well dimensioned power-capacitor and some other components. :o) Only 1 Euro for the whole thing! I am shocked (look for the price of an single Xenon-bulb)
Hi Folks,
yes some electronic parts become very cheap. Your pic shows a flyback-transformer( Zeilentrafo) which you can get at every dump ( Wertstoffhof ) Look for old PS-Monitors or TV.
I recently got a 12-torus-transformer( Ringkern-Trafo) 100 Watt for 5 ?. I could not believe it either.

Kator01,
what are the odds! :o
A few days ago I bought a used 200VA toroidal transformer on ebay for 1 EUR! Okay I payed 8,90 EUR for shipping, but who cares? ;D
Dont' know why there are no bids on this article.
