O el esquemático

I hope , I been watching a lot of videos , my biggest concern is the working piston I made from grafite but it is not a perfect seal , I might need to machine a new one . This is not the best aproach , the top plate should be aluminium so it would dissipate the heat faster , but I used acrylic so I can see the displacer piston moving , might upgrade it to aluminium later , I am gonna send you the video that inspired me to build this thing , as you can see the displacer is magnetically coupled that is what they call ringbom , I just need to glue the top and bottom plate seal everything real good , and put a cup of boiling water under it and some ice on top , I hope it works

I want to see if it works first hehe , did not finish it yet , voy a tener qué cambiar el cd de arriba porqué es muy blandito y se flexiona todo , creó qué voy a usar un acrilico de 3mm qué tengo , lo ideal sería aluminio porque disipa mejor el calor , pero no se podría ver cómo se mueve el desplazador adentro , la idea es ver si logro hacerlo funcionar con una taza de agua caliente , LTD significa low temperature differential , tengo otro comprado qué funciona 2 horas y pico con una taza de agua caliente , y quise probar de hacer una versión casera

Thanks brother

Viste y es muy fácil de hacer , habría qué agregarle un multiplicador de voltaje a la salida para qué llegué más arriba qué 100v , lo hice con ésas fuentesitas para de 220-12v para lámparas dicroicas qué siempre se queman y tengo vários tirados por ahí , por lo general tienen esos transistores y algun toroide o inductor de ferrite

12v

Is just a pwm generator with very low duty cycle and low frequency

@@rodriguezfranco3839 hmm so I don't really know that's mean. I am not a electricity guy just passing thru. Is it capable to detect frequency or no?

@@elderizm It don't detect frequency , it just produce pulses

@@rodriguezfranco3839 Thank you so much for the answer. Look like chatgpt gives me wrong information 🤣

@@elderizm chat GPT works like shit , a few partners wore trying to use it for a college team work since we needed to make a code for arduino and no matter how we explained it allways gave us the wrong code , I think the paid version must work better and the free one must give wrong answers on propuse

Exactly the capacitor bank is charged by a little zvs powered by two small cells , I tried powering it with better 3 cell lipo once and it was able to sustain a higher pulse rate but the inductor on the zvs started to melt heheh , in this video I was stopping the zvs at the higher pulse rates to let the cells rest , that is why it was dischaging the bank so quickly , I should power it with my variac , but the output still kinda small , I want to build a half bridge next , I am looking for 1 meter arcs hehe

@@rodriguezfranco3839 Haha! I've been there... What voltage does your capacitor bank need?

@@SuperBrainAK it is two 3300uf parallel + two 470uf in parallel so 7540uf I can get them up to 160v cause the sstc driver wont take more than that

Thanks for checking it brother !! Yeah it must be a couple thousant volts , but it is the frequency what makes the air ionize thus allowing it to conduct for such a long arcs , that coil runs close to 300khz , you can touch that arc and only feel a little bite , but it is perfectly safe

Fake mosfet should work anyways , which fets did you buy ? What country are you from ?

Thanks yeah , I need to start thinking on a half bridge , get some gate drivers , GDT , and switches ( I might try to go staight to igbts instead of 460s ) , I am thinking on trying one of those halfbridge gate drivers like the IR2153 cause I think it does the dead time to avoid both switches to be open at the same time . Anyways can you hear the pop sound it makes on some of the arcs ? Sounds kinda the same like your last video was doing

Now that I think about it , the GDT should fix the problem of having both transistors open at the same time . Do you think with a UCC37321 and UCC37322 pair I could drive a halfbridge of 60n65s in CW without heating up the drivers ?

On the comunity section there is all the info needed to build this coil , it is magneticitist class E single fet schem + magneticistist QCW buck converter + finn hammer arduino uno ramp generator

Thanks for checking brother !!! Yeah I need tubes in me life hehe , I need to start collecting parts , I am allways looking into online sellers near me, once I almost buy a 833a but it was kinda expesive and I lost it , here in my country it is impossible to get soviet tubes , apparently they never got in , international buying is kinda hard to do here .

There is a seller near my are selling a used toshiba 5p70 "power triode tube " I don't know shit about tubes but the thing looks super cool even for a desk decoration , tell me brother , would that work for a vttc ?

@@rodriguezfranco3839 I dont see why not, looks good for a medium size vttc

I already posted everything , you just need to look into it

I just almost finished , I just need to add a pot for the bps , and a switch to make it run or stop it , to use the oneshot buttom , I am gonna test that buttom in a while , cause last time I tried it did not work , now I put a debouncing circuit to the buttom and we will see if it works

Fuaaa dónde hay vídeo de eso? Voy a checkear tu canal pero no recuerdo haberla visto , están interesantes pero es por pura experimentación porque uno de aire comprimido siempre va a tirar más

@@rodriguezfranco3839 desafortunadamente cuando hice ese experimento no subía Videos a TH-cam. Aún lo tengo un poco desarmado pero algún día lo voy a volver a amar y voy a subir un video

Yeh it still looks ghetto build but is better than having everything just laying around , plus I am thinking on taking it to my University if I can get in contact with someone from the EE lab , so I need to have it build more sturdy in case I get the opportunity to take it to the lab , at least I would like to take just the buck to see how much ripple it has , the pll driver I am not sure if it will survive the travel heheh the gate driver is extra clunky looks like it would desolder into pieces if not treated with caution

Thanks for checking brother👍

Thanks brother !!! How is your QCW build going ?

Hola Amigo !!! Si debería llevar un diodo , pero como es muy poca potencia y los capacitores no llegan a descargarse del todo pienso qué nunca se llegarían a cargar de manera inversa , igualmente ahora qué lo mencionaste voy a agregarle aunque sea un pequeño diodo uf4007 para evitar el flyback , con ésos capacitores así cargados después del vídeo probé y llegaron a hacer unos 5 disparos más sin cargarlos . Deberías probar tus capacitores con alguna bobina pequeña cómo estás qué son de relays, no creo qué sea muy grande el flyback con estás mini bobinas (igualmente no está de más agregarle un diodo )

Thanks yeah , I been trying, if I raise the primary a bit , it gives very short arcs

Oh hfsstc are not easy , I tried to make them two times , and never got them to work

I want to see that , a buck made with tl494 that sounds cool

@rodriguezfranco3839 just a simple tl494 pwm with paralleled outputs with a 1-2 uf electrolytic cap across it direct to gate n source to the buck so it basically slaps the load with a near perfect ramp⚡️👌😎 btw also utilizing 18650s for i/c power🤓
