Master modder ZapWizard has completed work on version 3 of his home built powder coating gun. Powder coat is applied using air pressure to blow negatively charged thermoplastic particles onto a grounded metal surface. The metal part is then baked to make a hard finish. ZapWizard’s gun uses an air pistol with regulator at the bottom operating at 15 PSI. The powder is held in an acrylic kitchen canister with a reinforced seal. The final element is an ionizer element placed in front of the discharge nozzle. Version 2 had a trigger operated switch for the ionizer, but that was replaced with just a simple toggle.
very nice. I woder what he uses to negitivly charge the powder, all you see is a black box…
negative Iron generator, I use this to apply static grass, sorry no idea how many volts. Static grass aplicator use 12v power 20,000v negative ion.
Lice hate powdered sugar

nice diy hack new stuff this is what we need still no leds keep it up boys thanks steve
interesting how you can give a complment and hide an insult in it steve. And I would appreciate it if you did not speak as some magnificent power, as if everyone is out to please you.
salvage a flyback trafo from an old TV or CRT monitor to make a HV power supply:

Makes for a much cheaper “Ionic Breeze” I’m sure..
A flickr (ew, bad enough) photoset with 6 images and no other information is enough to get on hAd these days?
steve i dont see this project that good till it has 50 million leds
please, a how-to, or some parts list, or something besides a few pictures? I’d love a real building blog or something-this is just a cruel tease at best, or worse, does this thing work at all and we’re all just suckers for buying into it?
Now we need to find a way to bake the stuff on without ruining an oven and rendering the house uninhabitable. For those of us in apartments, a second powder coating oven is out of the question.
very cool…. I think my roomates would kill me though (no garage). I don’t see how it would ruin an oven (that’s why tinfoil was invented :P), but the smell of plastic kinda sucks….
At least there was 1 led :D
the shnozzberries taste like shnozzberries! :D
hmm guess you guys didnt see its called hackaday not howtoaday
I appeaciate the hack, but a powder coat gun from Harbor Freight is pretty cheap. I have my own powder coating setup- HF gun (<$100, but mine was a gift), used oven ($30). But you also need good cleaning to get the coat to last (start looking at media blasting and sanders, and chemicals to de-grease before you coat). Don't forget the vent fan and particulate mask. Once you get serious, you'll want a non-contact (IR) thermometer. High temp masking tape when you realize you don't want to coat everything. Buying the powder is where the costs really start to rack up, and I don't see any way to hack that.
Well if his previous iterations of that are anything to go by, then yes it does work. I have seen the other 2 and they do a great job. Nice and even coat from what I have seen.
nice; however, you can get a good powder coater rig from harbor freight cheap (on sale $70)
The flashlights in the last picture cost $145 each…..They are smaller than a pack of gum!!

I don’t see any reason you can’t use your oven, as long as the part is sealed inside something to prevent powder from shaking loose and contain fumes. An oven bag should do the trick, it will stand up to the heat and still allow you to see the part. Make sure you keep the bag from touching the part. A metal cage from the petstore would work for this, it would support the bag, and give you something to hang the powder-coated part from. After baking, take it outside to open it up and air it out. In case there’s some volatile component that can pass through the bag, ventilate your kitchen while baking, and crank the oven up to maximum temperature for a while afterwards. After that, if there’s anything left over, it should be stable and non-volatile enough at normal baking temperatures that it won’t taint your food.
@4, thx, @1 link was posted in previous versions..updated.
@5, there is a superbright 10mm RED led on it to tell you the ionizer is on.
@6, While that would work, it’s a bit more dangerous. The above ionizer is cheap, and is pretty safe.
@7, because it’s the 3rd version, and I was put together in 1 day.
@9, All of the brass parts are visible there, they are all parts from the plumbing area of Home Depot or Lowes. The pistol handle isn’t availabel at Home Depot, but the same thing can be done with the part I used in Ver2
You can get the kitchen container at Bed Bath and Beyond for $5.
It does work, there are photos of powdercoated stuff in my flickr account, there is a link to a video in the first photo.
A toaster oven is big enough for many parts. I use it 90% of the time.
@10 – When the powder is curing it releases gases. It’s just not recommended to use the same oven you cook with.
@16 Yes the harbor freight unit is supposed to be pretty good, and I actually powder from their store. I did this project as one of the Austin Modder members bought a Sears model (breaks real quick) that got us hooked on doing powdercoat. At the time I built Ver1 I didn’t have a compressor, I was trying to duplicate the Sears model using a high speed fan.

i thought about building one sometimes its not worth the energy versus the cost

Only $56 with 20% off coupon. Does that make it doable?
Intimately, the post is in reality the greatest on that worthy topic. I match in with your conclusions and also will thirstily look forward to your forthcoming updates. Saying thanks will certainly not just be sufficient, for the amazing lucidity in your writing. I definitely will right away grab your rss feed to stay privy of any updates. Authentic work and also much success in your business endeavors!
Awesome idea – can’t wait to give it a try. :)
how to make this generator? the circuit too small but it able to generate up to 100kv from 240vac input supply..can someone please explain this..?
Harbor Freight powder gun pretty static price @$70. but don’t forget the very easy to obtain @20% off coupon which brings price down to $56. Not worth messing with DIY effort currently (but still kudos to author for doing this project)!
