Thanks you so much for your videos. I have already bought the two parts you used on your earlier design and I was about to get started, luckily I decided to watch some more of your videos and I am now ordering parts to build your new version. Originally I was researching a way to build a gun that would use tribo (static, I think?) but when I saw your video, it seems much simpler to build your version. One thing my teachers at trade school tried to teach us, was that while it was good to learn from our mistakes and experiences, it was much better to learn from others mistakes and experiences. One thing I could really use some help with, is deciding which resistors to use at the end of the cascade? I have found 15 megaohm resistors on aliexpress, but there are some that say they are 1/4 watt, or 1/2 watt? Could you possibly point me in the directionof the resistors and perhaps the number of them that would be the best.(it would be really great if you could link to somewhere with the correct ones? I have also been reading that it can help to have different outputs depending on the shape of the part being coated? Is it simply a matter of using a variable power supply, or is it more complicated? I was also wondering if it would be possible to have some sort of digital readout that would somehow correspond with the variable input, or output? Once again, you are absolutely amazing!!

Hi. KZread somehow unpublished and held this comment. I just found it now. The high value resistor is not essential. I guess the PC gun manufacturer put them to prevent arching which is a fire hazard. You can do without it. The voltage input is fed to the primary of the transformer so ideally the output voltage is proportional to input. So yes I just adjust the input voltage. Don't know if you seen it yet but I made an adjustable power supply with digital voltmeter for use with this circuit.

I have noticed in the commercial designs that the ground is connected to the positive side of the first stage in the cascade because they are negative output which makes sense however because the arcs will then be going across the diodes I wonder if this puts more current through them and makes the final resistor more important, one of the reasons you probably haven’t already burnt them up.

@MrBrettStar

I just did some test and the current across the diodes is the same regardless the end resistor helps but doesn’t matter too much if the input current is already low. In terms of what side the earth goes on when connected to negative side you get a constant voltage whereas the other way it will fluctuate between positive and negative the initial voltage

Phil I switched things up a bit because the little 15kV unit powering the cascade is so fragile and in my opinion a weak link in the system. Im using a ZVS driver to power a flyback transformer to get high voltage. Im getting an arc from 2.5 to 5 cm depending on voltage fed into the ZVS. However I dont hear the buzzing sound with this new system. I also tried feeding this into a cascade just like if it was the small 15 kV unit, but I get the very smallest discharge corona. Super small. Without the cascade, I get a large discharge between the positive and negative of the flyback transformer. Can you help me get this thing to produce negative Ions? If it needs to connect to your cascade, where do the + and - connect?

Hi. The DC input is based on the input requirement of the 15 kV high voltage generator kit. Which is 3.7V to 4.2V, 2Amp. According to the manufacturer, the input DC voltage can be increased to as much as 12V by increasing the value of the feedback resistor. The kit is originally supplied with 150 ohm, I actually changed mine to 470 ohm and I can increase the dc input voltage to 6 volts. There are many KZread videos out there about this cheap 15 kV HV generator kit if you need more info.

Hi. For the resistor try to use 1 watt. It only has very low current. Regarding the actual output voltages with respect to input voltage, I'm not yet sure at this point. This is also what I want to investigate further. I will post more updates. But in powder coating, you want to have the ability to adjust the energy of electrostatic charge. Normally we want higher kV on flat and big surfaces, and lower kV on intricate parts.

Hi. I just bought that small PCB of the high voltage generator that contains the oscillator, online. It is a very cheap kit made from China we can buy on online shopping app. It is a simple circuit that only has 1 NPN transistor, 1 feedback resistor and diode.

What is the resistor at the end of the cascade used for? Current limiting? I used a 1 Mohm resistor but it burnt out rather quickly. Still shows 1Mohm but think it's arcing internally based on the sound. Do you need high voltage resistors or do you think my problem is caused by something else?

@DIYPhil

4 ай бұрын

Hi. The resistor at the end is used to limit the output current so that you will not over charge the powder. Over charged powder will cause back ionization that will repel the subsequent powder you are trying to deposit to the part. I indeed had the same problem with the resistor arching between leads making it useless that is why in subsequent videos you may find that I did not use resistor since I had no solution to this arching yet. The resistor must be covered with insulation to prevent arching. In my latest gun version, I simply cover it with candle wax. Professional units had it covered in potting epoxy. I will have a video coming up taking a closer look at the cascades.

Which diodes and capacitors did you use for this build? I have an Eastwood powder coater and I am not happy with it, I think building my own from your description could be better.

Hello, still in progress of building and experimenting with mine, ive seen in comments on latest video that you are experimenting with powder pump what im looking forward but im wondering if you tried anything with adjustable voltage, since this schematics is over 100k voltage what professional guns dont have since it can create holes in powder and for some detailed objects or powder with effect they are using around 50K, the module that you recommended has 15k fixed pretty much so its not adjustable. im thinking if maybe it would be possible to have stages separated but that would need high voltage relays and it would need to be outside of gun with powersupply so there is problem with how thicc insulated wire would be required from power supply to gun, just wondering if you have been experimenting with this, but i love your work!

@DIYPhil

Hi. We can adjust the output voltage by varying the supply input voltage. According to the manufacturer, the 15kV kit will work from a supply voltage of 3.7 volts to 12 volts (need to change the feedback resistor to 1.5k ohm). The primary winding of the transformer connects to the input voltage so it has a direct effect to the output voltage. The high voltage of the cascade is difficult to isolate. In one of my later videos, I showed that the spark jumps out from the thick insulation of the final output when it came close to the grounded metal part of the gun. That is the reason why all professional commercial PC gun has got the cascade located on top of the gun, so that the high voltage does not have to travel far.

@DIYPhil

Жыл бұрын

I also would like to add that the cockroft-walton voltage multiplier that we assemble with diodes and caps is not ideal. There are many power loses in each stages due to inherent characteristics of the components. I doubt if my gun reach 100 kV at all. When I try to increase the input voltage at some point, sparks jumps within the transformer windings (until it burn out the insulation), and even between stages of the cascade. I try to stay at about 4 volts input to prevent stray sparks. The better circuit will be duplicating the commercial voltage cascade where they used about 10 stages. That means less voltage on the transformer secondary winding and less voltage in between adjacent stages but still reach the 100 kV output. That will be my next circuit to experiment on.

Thanks for the video I want to know the quality of the diode and the quality of the capacitor that you used

Hi. You should be connected to earth ground. If you look at commercial powder coating gun, the handle has a metal strip. That is for grounding the operator. Look at the circuit diagram I show on 3:59, the ground symbol must be connected to earth ground. When your body is touching a metal surface connected to ground, you prevent build up of charge and makes you neutral. Look at my subsequent videos of homemade powder coating gun I show wiring more clearly.

It has the simple circuit diagram. kzread.info/dash/bejne/k5WAxZiEXdWeecY.html

thats it? its so easy

Specs on the resistors at the end? Also why does the high voltage cascade need to be on the gun? Cant it be in a box nearby?

Hi. I used 1 megaohm resistor at the end just because that is what I have. The commercial cascade in the example have 4 pcs 15 megaohm resistor in series for a total of 60 megaohm. The resistor is there to prevent the powder coating gun from creating a glowing plasma and arcing at the electrode tip for safety reasons. You can see in my initial test in the dark 8:26 that the spark want to jump before the resistor, not on the end. The value of resistor is something I want to investigate further so I intentionally left that out in this vid.

As for why the cascade needs to be on the gun, I looked at all the professional powder coating gun and all have their cascade at the gun. If the cascade is in a box, then you will need a heavily insulated cable going to the gun because that will carry voltage in the order of 100 kV. In comparison the spark plug cables in a car is made to handle only up to 45kV and they have diameter of about 8mm. The hobby guns like Eastwood and harbor freight can get away with the HV generator in the box because it only generate max of 30 kV. The other reason is the switch incorporated in the PC guns. It is easy to connect a switch to the low voltage side of the cascade within the gun. Hobby PC guns mentioned above have the switch in either hand held push button or pedal switch so it is less convenient.

@@DIYPhil Have you seen the other common vid on homemade gun that is on KZread. It uses the pulse system you didn't like in your original gun. How do they get away with the power supply off the gun and just thin wires running to the gun? I'm not sure that results are affected by the pulse as much as it is in pipe design, 90 degree angles, and poor air flow because of it. I've seen some good work with the pulse system and designing for input output air flow

@DIYPhil

@@srknyxl In theory, the voltage rating of the capacitor in the cascade should be 2x the transformer peak output and thus 30kV. However, I do believe that the actual output is less than advertised as usually is the case with these Chinese-made kits. And besides, we are not applying the max. input voltage to the circuit, so I really don't think it reach 15kV. I suggest that you assemble the first stage of the cascade with your 10kV caps and see if it will not fry the caps. The first stage only composes of 2 diodes and 2 capacitors.

The voltage on the cap needs to be rated more than the voltage of the transformer. If you are using 15KV then you 15KV +

Hi. Some people use ignition coil with success. I actually tried it with motorcycle ignition coil which is not too different with car's ignition coil. The problem is those coils have iron core and will not operate at high frequency due to core saturation. The voltage multiplier circuit as can be seen in the video require frequency over 10 kHz to work effectively. The other issue is the size. Those are big. You can see in this video where I tried different coils for the high voltage generator. kzread.info/dash/bejne/h2Zou5aKftTbiJc.html

@DIYPhil

I don't know exactly your set-up but my guess is that there is not enough current to actually create an electromagnet. The unit of magnetomotive force (MMF) is Ampere-Turns. The output current of the voltage cascade in the video is only in the order of micro amperes. Very very small.
