Modular DRSSTC 1



Jo, this modular sounds maybe HV technician jobs something funny, but if I now the whole drsstc 7 call I eye soon Garnich more, so let's go now again going on at 1 and I also explain can the modular has to

so after at the Tesla thon More or less all rewind me harm worn of which have, I got made me what is Yes not bad, because ego get out again, me for my subsequent projects, still more effort and time to To give. Modular means to distribute easy that I will now start the drsstc in sections where I search out the best way me at each section as safe and functional as possible to make the whole thing... the modular drsstc1 is a real crusher and I got to the goal set the whole thing before 2007 to the running, given the whole new developments is nevertheless still quite scarce.

Within the next few days, I get a dose of 9 pieces Fuji IGBT modules that I quite cheap could bid on ebay. Each module take time and 800A 400A peak at a maximum voltage of 600volt. It will I together make a full bridge, they could then theoretically 1, 6kA peak, three times as much as my current drsstc6
. I'll start today with the powersupply, and even that will have it. Of course also modular design it will have voltage limit an adjustable so that one bridge the elcas for the eg just to the test on maximum 100volt loads or for full power sometimes takes 300volt. also Of course a voltmeter and a self-adjusting automatic loading system, this time with a comparator. in the powersupply with included are Of course also the + 12 volt electronics and 15volt for fan, + 30volt and 15volt for the pre driver of the igbt bricks. the pre driver is a full bridge irfp460aufgebaut, each 1gdt per igbt with a ratio of 1:1... bridge the elcas for the 350volt in parallel are constructed from 2 x 12000yF total so 24000yf 350volt. dekopplunkskapazität which bridge is expected to be approximately 100yF. Fkp1 on that series, so I thought to the 500nF, and 15 mm copper pipe for the primary coil come this time wima as mmc. The secondary coil should have around the 70 kHz, so these will be great way this time, as the toroid, because I can get first then 3 kg filling PuTTY, hehe... well, also come some new features for overcurrent the n section (also n own module) real time reading of reference current and primary current, overcurrent in 2 steps, once at ca 1, 4kA Go ahead the down set the on time, 2nd level of is a complete turn off bridge at 2kA ca...

the dimensions of the coil should this time relatively gigantic footprint of 50x50cm, need to be ne already wirds, otherwise fits the best sake not everything in

to do so again, does anyone HV testing have idea where I ca get 100 Watt power resistors with about 30ohm ne? and I need 2 mega fat heatsink so 30x50cm with neat Finns turn... well, from the powersupply wirds next week probably more information To give, first is because it focuses as long as mine are Not yet as igbts.

on each case of 2 meters, got spark length to the objective set and that the drsstc against every little thing is secured. also the interrupter is half computer, but more about that later

need help



This bulb has a normal E27 high voltage cable jointing version and looks (image from google is exactly that I have here)

and I sometimes just photographed the version, she has 2 connections and work as an electrician at me on the (that has participated due to time constraints not check can, only in the night shift on Monday) and he said that needs no ground

The maximum length is 1 m others.


Da man the ECG net can see on the image (data) can be man so not to testify because we know neither manufacturer nor type. It can also be that fits this ballast to the lamp? We also don't really recognize

cable is not longer than 1 meter :-)

and the device is not original (think the original is by phillips) haber is expressly for this thought it was sourced from ebay (see link) have here again a picture of the complete ECG made pet her something entscheidenes you can read out and Yes this ECG is according to the seller (a shop no private) suitable for the lamp

250V is amended by
Output of your ECG 4KV so 4000V did you a voltage tester for 4000V?
What's say on the bulb? and here the picture version and is suitable for the lamp

Coil gun



Hello everybody!

I don't know with the legal testing jobs situation and want to ask if a coil gun is classified as a weapon or not

Because if one part that really matches and corresponding energy on the projectile brings eateth already dangerous!

Hello, erstma...Caveat: A Luftgewerh. counts according to law as a free weapon, if it does not exceed the muzzle energy of 7.5Joule. The permissible limit is spin (Flitschen) at 21(!) Joule...You must have a fucking great Kondnesatorbank to get a such PROJECTILE energy, because Coilguns are something from inefficient (I believe skip to 3% of the energy stored in the database in projectile energy). I think that most likely the Bank is dangerous to the whole thing. She can actually tear off limbs... and cause severe burns (if mans also survived).
The last thing a Coilgunbastler should worry is the legal situation, I find. You should first develop the part and mainly the materials get, that the part is not too bulky and get that first air pistol level...

So did today a small test coil gun built 1Spule, operated with a 12 v car battery (for high power).

Look not so bad but still needs to be improved
(capacitor bank, 3 levels [coils], compact design)

does anyone know of a German-language site, where it ne instructions for a coil gun is?

So far I have only English gefunden(ist zwar np aber deutsch is angenehmer) [English LK: oops:]

or someone (or more) it is interested son thing to build and share experiences here?
Maybe there's already which are already in the possession of a CG and want to help?

It is very interesting to experementieren Flash devices, single-use cameras. Could be several stages zusammenbasteln...ich didn't shoot him across a spring bolt (steel arrow for air rifles) with a stage across the room and he is stuck in ner wall! You could develop further...Spring bolt go quite well as Masatoshi and cameras are suitable as sources of energy for small, portable Modelle...man should remember times n wasting some thoughts, n is a good starting point.

Whenever I think about the topic "Coilgun", can I get after a few hours of "reason" and realize that I shooting much, much, much harder with my AJS, air pressure gun, and the thing is also electrically and shoots not only ferromagnetic...
Is actually, what excites me because is there is sone "futur Waffle" and otherwise no one has something. Energy efficiency is so miserable...

If you want to have what electric to the shooting, then to build pneumatic gun is son to "old skool TEC".
If you want to have a future toy under Softairniveau, to build sone Coilgun.

Excites me actually only HV electrical to build something the functioning of the shot energy is it just crap...

If everything works then I would then shrink it and build it into a housing, then it has a great "toy"
