You should put a geiger counter to it, you could probably detect some x-rays! In fact, vaccum tubes were how x-rays were discovered in the first place. A photographic sheet started to fluorese when placed in the direction of the electron beam, even passing trough objects
Just stop propaganda motherfukr you are idiot trying to debunk the truth he was using rf and it was burning like flame not like your shitty elerctic arc 😂😂😂😂😂😂
I have been interested in something similar to be used to clean up brass casings from the ground. If there was enough force to pick them up, this would be a great solution vs trying to build a metal separator.
As a nonprofessional i must say you axplained some stuff i never heard one explain like this for a vttc thanks for that. Awesome arcs too for that small coil
I don’t get it, I must be dumb or something… how can the power tube filament be at 6VAC and -3KVDC simultaneously???? I’m obviously missing something. All I know is tube filaments are extremely sensitive to voltage so how would it function with two different voltage sources and at ac/dc??? How does the the tube differentiate between the two sources? I would think the 3KV would blow the filament instantly. I can’t find an answer to this anywhere, the book I read just assumes you already know why.
I wonder what to do in situation faced by me? The two Neutrals from the two outputs 230 VAC of the Nitrox Inverter ( 3 KW - 24 V, SP - Hybrid _ by A.P.T. ) aren't allowed to be jointed! The Inverter demands the two Neutrals to be isolated and afloat! I'm rather perplexed. Obviously the two Phases are certainly to be distributed isolated! The problem faced has been that either regular Load RCD or the Smart Load RCD have been in the habit of tripping off upon Grid On / Off since installation. Even sometimes the RCD on the Input to the Inverter also goes off! The reason: the wiring of my home has become leaky for sometimes. I've been curious about the Phase difference of the two outputs of the Inverter. Is there any way to examine it's two lines 230 VAC (RMS) each. Probably phase difference of 120° with about 460 VAC (RMS) that amounts to be ~ 651 VAC RMS ! Moreover, the grounding croc clips of the O-Scope share the same common ground! Is there any way to compare the 2 outputs, one 'Regular Load' and the other 'Smart Load' be visualized on single O-Scope screen with custom devised High Voltage Probe(s) X100 on single or Dual Channel OScope? Note: The Inverter trips the RCD's on bringing the the neutrals near each other. I'm a medical doctor, who happened to be a life long Accidental Scientists. Help is awaited!
Your coil works great! But I fed the tank circuit with HV directly and used a NOS 6.3v filament transformer with a 2 nanofarad filter capacitor across the output and one side grounded. HV is applied to the anodes of 2 572B triodes via the tank circuit. It seems like the voltage gradient between filament and plate might be the only thing that matters really. Guy named Evans posted a twin 811A triode circuit here and mine's based loosely on this. He might have adapted it from a similar curcuit I saw in 1972. No MOT's then! Real plate transformers were big bucks especially for a kid like me lol delivering newspapers. Anyway rock on it's all good.
Not sure of the validity - but have always heard that you should power up the filament first to get it up to temp before applying the HV as it will, supposedly, prolong the life of the tube......
I haven't heard of that... I have damaged a few tubes but the filament still works! overheating damaged the grid or vacuum quality, filament burnout hasn't been one of my problems..
@sparkstarter IIRC, something about it "hardening" the filament so that the thermal emission of electrons is reduced.... I know that for some of the early radio tubes, you could "rejuvenate" the filament by applying a voltage a bit above the rating for a length of time (with no hv applied). I've tried it on a few radio tubes, and it's about 50% successful. It brought back a few that had no emission.....Search vacuum tube rejuvenation for details....
What you are doing is creating a shaded pole linear motor. The eddy currents will hold nonferrous stuff at the null point.A much easier way to separate the ferrous and nonferrous metals would be to use a series of regular ac electromagnet and have the mix pass over them at an angle. You get the metals sorted by ferrous closest to magnet, non metallic or high resistive in the middle, and nonferrous to the outside. Works great to sort scrap or mining gold from gravel.
I'd certainly agree that repulsion is more efficient for separating nonferrous metal than is attraction. However, I think the shaded pole analogy doesn't quite fit here. Shaded poles have just enough copper to shift phase of magnetic field through the shaded pole but not block field completely. At 60kHz, the copper washers are blocking almost all field through them rather than shifting phase.
LADIES THIS IS COMPLETELY UNSAFE. Ridiculous. At least use an isolation transformer. Don't have one? THINK!! Gut out a pair of similar wally worts and use two transformers back to back, AKA 120Vin / 12V out-----12V in/ 120V out.
there is always a danger element (shock or fire) when working with any high voltage device. The capacitor serves to limit current flow through the circuit. Not sure what extra safety gain your getting by using an isolation transformer other than some EMI filtering...
@@sparkstarter The tools, two I think, were made by Maxwell Magneform for Boeing to fix small dents on airplane skins. Cheaper than dismantling inside to pound out dents. Pays for itself in reduced air drag (reduced fuel costs). However, the mechanism is a bit different. Your device will repel any large piece of aluminum or copper. Only pieces of similar size to copper disks are attracted. Next comment refers to your setup as a shaded pole linear motor. I'd think of you device more as pushing the aluminum or copper from back side. Magnetic field is expanding around perimeter of aluminum. There is little field close to copper disks. Thus when aluminum is close to disks, there is more field on back side of aluminum than on front side adjacent copper. Back field pushes aluminum towards copper where field is lower. The Maxwell Magneform machines instead use a time dependent function. Aluminum is repelled weakly for a relatively long time to build up current, the attracted hard for a very brief time.
Why dont they make the spark go from a positive and negative end of wire from the secondary only, why does it connect to the primary. It just seems weird
In an auto the negative is chassis grounded to the Car. If you examine a spark plug you see the arc jumps from the central electrode to the metal casing which is in contact with the engine block.
But..but..think of tthe beneficial Earth tremors...and the added flavours to the water supplies..to say nothing of the provision of basic nutritional sustenance to the emaciated wo£v€$ of Wa££ $t and the City of £ondon.
Yep, I had a similar circuit set up years ago. It was hooked up to 240v. I got a jolt from it that nearly dropped me and I never used line AC as a direct power source ever again. My favourite power source since then was 48v dc a much more user friendly voltage for HV generation.
Either depending on frequency and geometry. In general, low frequency will attract iron because iron is ferromagnetic. High frequency will repel iron (except in unusual geometries such as in this video) due to iron's electrical conductivity. And, of course, any frequency above DC will repel iron if iron is hot enough (above Curie temperature) where it is not ferromagnetic.
I don’t know if you are aware of this, but you have been exsposed to a good sized dose of XRays in doing this experiment. I hope for your sake you take precautions against this as they can damage your DNA so you should keep a good distance away from the high voltage ark and the corona especially. For more information research: Bremsstrahlung or braking radiation.
In addition to the resources mentioned, the area also had a rich vein of high quality clay which made the area the pottery and brick production area it was.
Why are you drawing your arc to the top of the primary winding instead of the to the common lead? You are feeding back high voltage to the coupling cap and back out onto the AC line. I saw that you have absolutely no line isolation or filtering. Your neighbors must love your RFI. I recommend a common mode choke on the input AC line as well as an isolation transformer. Your entire set up is a guaranteed lethal accident waiting to happen. I work professionally with high voltage power supplies all day and intentionally drawing an arc will get you fired. Or at least severely reprimanded. Not to mention all of the accident report paperwork!
Been playing with this setup for 30 years without incident, and I would bet I work on bigger high voltage supplies than you do... but hey, everyone has their own safety tolerance. If you don't feel comfortable with 100W of power at 25kv don't mess with it.
The main power limiting is the 17uF cap, without that, the primary would not be happy. Regarding the open circuit voltage test, that is really bad for the secondary insulation, it will break down and eventually ruin the secondary insulation. Thanks for sharing.
Okay … that’s pretty interesting as a type of deliberately “weak magnetism” I wish you had gone into measuring the “magnetic force”. I wonder if the attraction/repulsion due to size of material could be exploited to produce a significantly useful amount of work?
