Hi, Thanks for your nice video. someone please answer quickly. I want this circuit to for charging a 450v 680uf capacitor for a coilgun. I made the circuit but when I connect the battery, nothing happens and the capacitor just charges to 12volts(this is the voltage of the battery). I changed the IC several times but it doesn't work. I made the board exactly as you said and my battery is 9 amps 12.5 volts and I also tried using a breadboard. What is the problem? and what is the voltage of your capacitors(little ones on the board)?
well sry for late reply , there could be a problem with ur circuit or with ur mosfet, make sure u check the circuit again and again. the ceramic capacitor are standard i never check its voltage coz it doesnt matter, if u did the circuit exactly the same like mine it should be good 100%
i dont have equipment to test the inductance but i can assure you if you use same size of inductor or a bigger one with 0.5mm coil it will work fine or it will perform more oscillation
The supply is 12v so you can use any supply 12v dc to power the circuit...you can use less than 12v too but it will take more time to charge the capacitor
Please someone answer. Can I charge the capacitor by connecting it to 12V ? Connecting it directly to 12V from the battery, waiting a bit and then done.
No no no if you connect 12v dc directly to the capacitor it will have only 12v dc ... if u connect a 18v to the capacitor it will have only 18v...that why i make a voltage booster to boost my 12v dc to 450v dc so my capacitor can have 450v of charge
Very nice video brother , very well explained and simple , those are very expensive capacitors heheh
well i got it from an old electronic circuit

Hello can I charge that capasitor with step up 390v DC?
sure
hey nice video! I was wondering, what happens if you don't disconnect the battery after it hits 450volts? does the capacitor explode?
yeah it could explode but i know there is a limit more than 450v and also the circuit will get hot and will take more time to overcharge
@@juleeboss is there any way to automatically turn off the charger when the capacitor is fully charged?
@@rodia_the_smg_guy5575 yeah but u will need another circuit to detect the voltage
can you explain me, i have 2 capacitor 450v 10000uf . One have volt and another one no volt, can we connect it together?
sure, but i will take more time to charge
@@juleeboss Thank you
13:05 why don't you get the shock?
well the things is i am touching only 1 probe , either one among the positive or negative
How would you charge a capacitor with a normal 9v battery. A capacitor bank with 333.33uF and 1350V
The same circuit i build in that video but instead using 12v u can use 9v
@@juleeboss Do you know how long it would take?
@@vineethsendilraj8577 it should be fast enough because the capacitance is low and only the voltage is high.. around a minutes may be or less
Can i put this under my bed?
How much is the inductor copaccity you used in this video?
i dont have equipment to test the inductance but i can assure you if you use same size of inductor or a bigger one with 0.5mm coil it will work fine or it will perform more oscillation
nice video....but becareful it can make you rip off 😁😁
well yeah but its Dc voltage and temporary like its not constant linear voltage
cool vid
How many UF is your capacitor ?
one was 1500UF 450V and the other was 2200UF 400V
Nice!
Nice
COOL 😎💕
Woow that nice
Can I just connect it to 12V just like that ?
The supply is 12v so you can use any supply 12v dc to power the circuit...you can use less than 12v too but it will take more time to charge the capacitor

I've simply layered 9-volt batteries to equal my capacitor charge, it seems to work.
@@matthewklose2255 yeah I managed to do it
How u have so many subs
becoz ppl like my channel :p
