Powder Coating Gun Power Supply Ignition Coil and TV Flyback Transformer 

thanks for watching and for being the first commentator.

wlang anuman. may kasunod pa po yan. yung mismong updated na gun

Thanks. I tried to make it as simple as possible for those that don't know much about electronics.

hola amigo la corriente es demasiado alta para el mosfetlo puedes ver a las 10:13 en el video enrollo una nueva bobina primaria para reducir la corriente al mosfet y no recalienta

yo use un mosfet que soporta el triple de la corriente que le puede dar la fuente de alimentación como 100 ampere o mas incluso . recomiendas darle mas vueltas al arrollado ?

@@jidukrishnamurti8114 ¿Qué transformador estás usando? puedes enviarme un e-mail a philipal2015@gmail.com

@@DIYPhil un tipico flyback igual al de tu video

In this video I experimented with the ignition coil and tv flyback to see if they will work. The TV flyback will definitely work but it is too big for my gun design. The ignition coil stop working at frequency above 700 Hz. The frequency for the high voltage cascade should be in the range of about 15 to 20 kHz.

Hi. Circuit diagram at 2:37. Most MOSFET used in switching mode power supply should work. The mosfet I used in the video is a 2SK3569 which I just recycle from old UPS board. Other people use IRF530N Mosfet, which is a common component.

Hi. I tried with and without that resistor at the end and did not see any noticeable difference. I have seen other videos in RU-vid with folks making similar high voltage cascade and they use the resistor at the end to limit the current spike that can destroy the diodes, as they say. So far I have not experienced broken HV diode, probably because I am only using low power, about 6 volts input to the supply. However I do intend to use a resistor at the end as soon as I find about 1M probably use 2 in series. I am only recycling components from old circuit boards and 1M range resistor are hard to come by.

Hi. You can send me an email at philipal2015@gmail.com or message me at facebook DIY Phil. I'll draw that simple schematic for you.

See at 6:34 for the second cascade I used 10 kV diodes which are cheaper and smaller. The second version of the cascade with more stages produce slightly higher voltage. Only a slight increase in the output voltage compared to the 5-stage version because I think the ac output of the transformer is not powerful enough to utilize the full potential of addition cascade stages. The 20kV diodes will work. I think in the first version I used 30kV just because that is what's available to buy that time.

May ZVS driver din ako. Nasubukan ko na ikabit yung maliit na transformer wala naman problema.Wala ako binago sa primary winding. Kapag nagka time i video ko yung zvs driver.

@@DIYPhil so no need na po baguhin ang winding primary kung zvs ang gagamitin? Btw, may center tap ung zvs ko uubra din un diba?

@@felmarz17 ahh ganun ba. kung may center tap kailangan mo i rewind. madali lang naman yun. yung zvs driver ko kasi walang center tap.

Yes. Mosfets have very similar characteristics. I just use the one I found from recycled electronics.

ถ้าดู RU-vid ในคอมมันมีการแปลอัตโนมัติ คำบรรยายแปลเป็นไทย ที่มุมขวาล่างของวิดีโอ ตอนแรกเปิดคำบรรยายคลิกปุ่ม "CC" แล้วคลิกปุ่มกลมที่ดูเหมือนดาว Settings > Subtitles > Autotranslate > Thai ลองดูครับ ผมใช้ภาษาอังกฤษเพื่อให้สามารถใช้การแปลอัตโนมัติโดย RU-vid เป็นภาษาอื่น ๆ ได้ครับ

@@DIYPhil ขอบคุณครับ

And for the casecade can i use 1nf 2kv?? I can't find 1nf 10kv or 30kv locally

Hi. The mosfet is used to turn on and off power to the transformer primary winding. The 555 ic output pin cannot handle the high current load if you connect the transformer primary winding directly to the IC output pin 3. You can buy HV generator kits that already have the mosfet. Try to search 20 kV high voltage generator kit. It is ready made and you don't have to build the oscillator and mosfet switch separately.

@@colorslaveworkshop2029 I don't think 2kV is enough. However, if that is what you have and you can get that cheap, you can try building the cascade with 2 or more capacitors in series in place of 1 capacitor. That will increase the voltage rating. The capacitance value will decrease but it will probably work.

@@DIYPhil ok thanks phill... So that the point of the mosfet, so i can use irf 520 driver mosfet module to replace your mosfet version right??

@@colorslaveworkshop2029 yes. it will work.

Hi. I just salvaged the actual mosfet used in the video from a junk UPS board and did not bother to look at the part number. You can use IRF520 N-channel Mosfet or any mosfet with similar specs.

@@DIYPhil thank you ❤️

Creo que sí

Sos un genio y muy generoso amigo . En el otro video podías usar el flybsck sin los diodos en una caja y luego ir con un cable de alta tensión de bujía de moto hasta la pistola y ahí usar la cascada elevadora de tensión. Creo q es posible yo lo estoy armando asi

@@gervasiokuz8926 Sí. No lo he probado pero lo vi a alguien hacer así usar el flyback sin los diodos en una caja y luego ir con un cable de alta tensión hasta la pistola

Soy de argentina Phil me interesa tener el desarrollo completo de esa placa pq acá son incomparables . Existe la posibilidad por favor de comprarte el desarrollo del circuito ?

Boss salamat at naging interesado ka sa videos ko. Hobby ko yang electronics at pagbuo niyang powder coating gun. May mga motor din kasi ako na nire-restore at binubuo. Balak ko i powder coating kaya ako naging interesado sa homemade powder coating. Sa ngayon kasi hindi pa rin ako nasisiyahan sa performance nung mga homemade gun ko. Kaya kung ano ano yung mga sinusubukan ko na setup. Kung sakali na makabuo ako nung unit na kampante ako sa performance, pwede din siguro ako magbuo pa kahit pa isa isa para sa mga gusto mag DIY. Siempre budget meal na presyo. Low budget lang din ako kaya makikita nyo sa videos ko karamihan recycled materials kahit yung mga pyesa ng electronics.

Oo nga ang galing nyo sir! Kita naman naman na tlagang bihasa ka sa electonics. Mahilig din kac ako magDIY. Pero mukhang di ko kayang gayahin mga ginagawa mo kac medyo technical. Goodluck nalng and more power sir!
