I've made a plasma speaker
Posted by geo bruce 7 years ago | last reply 7 years ago
Hello everyone, I am trying to build a plasma torch. What is a plasma torch you might ask? A plasma torch is used in a process call plasma arc gasification. I want to build a small scale working prototype for proof of concept. If anyone could help, it would be great. I can collect different MOTs or NSTs if necessary, just fill me in. Thanks for any input or direction.

Kid Robot's Dunny doll gets electrified when Dustin Cantrell puts plasma globes in 'em. The rest of the design is suitably space-y and the platforms complete the effect really well. It's a simple mod (like I'm one to complain about that), but it's pulled off well. Link

I got a asmall plasma cutter 110volt. is it possible to make it cut thicker material?? or do i have to use bigger transformers and stuff?? i dont no much about the plasma cutters. was also wondering if i could some how hook it to a lincon 225 stick welder? thanks for any help

I am thinking it might be fun to hack the speaker output on a digital alarm clock to somekind of plasma device that uses a flyback transformer. Something along the lines of a lightning alarm clock that was released a few years back.

Hey Instructables, We're StudentRND, a group of students in Seattle, WA that build cool stuff over the summer. We've taken our time over the summer to build a plasma speaker, and now are offering kits on Kickstarter! (As seen on TechCrunch and Physorg) What's a plasma speaker? It uses an electric arc to vibrate the air to play music! View the Kit <br>

Hello! I've seen a few of these plasma discs and was wondering if anyone know what voltage these things generate? I know its some high-frequency ac voltage powering the disc, but does anyone have a rough estimate? Just curious. I've been meaning to take one apart, but I don't think my multimeter could withstand a shock from it. (Rated for 600v).

I am in the process of creating a plasma tube, similar to those globes but made from an acrylic tube of about 80cm lenght. In my small scale experimets with a glass bottle instead of the tube I was able to find a way to mix some Argon gas into the vacuum to create the type of plama arc I want. Problem is the HV part for the much longer tube and how to keep the input voltage at 12v to be electrically save. To drive the switching part of the HV section a simple quare wave generator with adjustable frequency and pulse width is used. In my current design I use 5V for the driver and 12V for a TIP122 that drives a modified flyback transformer directly. Now to specify my problem: The TIP is good for 100V and up to 5A with proper cooling. But I would need to make a new HV coil capable of delivering around 80kV at 12-30kHz - that is the easy but time consuming part. The primary side would have quite some inductance and I fear the TIP122 would soon get into trouble. So I was thinking of using a IRF260 mosfet instead but they need a proper gate driver for high and accurate switching speeds. To further seperate the driver from the hot action I thought of using a LED on the driver side connected by a fibre optics cable to the Mosfet driver. Would it be feasable to use good a transistor to drive the gate of the Mosfet directly or is a gate transformer the better option? Are there any shematics available for a gate driver that uses an optical input? And yes, of course I will make an Instructable if I ever get it all working to my satisfaction.

My freind is letting me use his CNC plasma cutter & so I thought It would be nice of me to offer to every here on intructibles to make them a plasma cut sign like in the pictures. right now the price of 1/4'' steel is about $2.50 per square foot where I live. The CNC plasma cutter makes really nice looking signs and can even cut out pictures, I can take a regular picture of a deer, an elk, a bear and cut it out. just look at the pictures below to get an idea. If you want me to cut you a sign out you can post a comment below and we will talk and fine tune the cost down. I prefer money orders, they are much safer for all of us. just not as quick. Thanks, Daniel

Im having trouble generating any kind of plasma and i guess not fully understanding this. Heres my setup: A metal pot with a Plexiglas lid as vacuum chamber. a pressure gauge on top A vacuum chamber A MOT as the power supply. Dont have equipment to measure high voltage but id guess around 2KVAC as thats what i understand is standard Two terminals about 2 inches apart inside of the chamber made from copper. one coming from the top, one from the bottom. I hook up the terminals , hear the nice MOT buzz, but nothing happens inside of the chamber. The mot has been tested and does work. Any clue or direction to point me in?

Hi there, i though i would post this here, as to draw attention, and also allow discussion.Due to making more and more items, i am running out of room.so, sadly, i am going to be selling my loved plasma rifle.You can see the construction and build quality here *Plasma Rifle -ible*All proceeds from the auction will be donated to Crimestoppers, who help out with a lot of anti-knife and gun crime over here in the UK, whom also happen to be having an anti-kife and gun week soon. the charity can be found here CrimestoppersI think the best way to sell this, is with a private auction. Basically, send me a private message, and the highest amount wins.The auction will end next saturday at 1.00am BST(note - if the private auction does not work, or for some reason not permitted i will then post the item on ebay)The rifle itself makes for a great conversation piece, to sit as part of your collection. Or for use in your latest indie film!Thanks for reading.Jakeps, this i also posted this topic under market place, but i wasn't sure wether that was the right place, or here.

I was watching the local news earlier... and they started talking about a new waste plant being built in Ft. Pierce, Florida.Basically, they vaporize the trash and sewage sludge under a vacuum, and use the by product gases as fuel for the plant and power turbines. Steam is going to power a local juice plant. Solid by product (rocks and such) can be used for construction etc.On top of that, the by product gas - when burned - is cleaner than burning natural gas or garbage. Even if you think climate change is a myth, I think you can appreciate cleaner air to breath :P This plant is going to eat up the local landfills too :)I just thought it was pretty cool. This is the first plant in the United States and the third in the world (other two are in Japan and are much smaller).Comments?

I bought 2 50" plasma tvs at an auction for $105 and found out they don't work. I've identified the error messages and downloaded the service manuals. But the manuals require I test certain boards and I don't know how to do that. I can't afford to spend $400-$800 to have a repairman fix them (someone at Justanswer told me that's what the charge will likely be). What can I do with these? Are the parts reusable for something else?

Hello, Just a few things you should know first: This is my first post on Instructables, and I am kind of new to electronics. I have a very old outlet powered electric fence charger that I recently took apart because it was broken. I took out the transformer and hooked it up to the wall (110v 60hz) bypassing a large resistor and capacitor and was able to get a stable arc of plasma about 1/4" long. As best i could tell the transformer does not have an internal rectifier so the output was AC. As for the voltage and the amps I can't tell, The limit of my multimeter is 500v and it went past that even with the resistor and capacitor hooked up to it and the output voltage is not labeled on it. I am hoping to connect a Flyback Transformer to this to make a Jacob's Ladder and possibly experiment with some plasma. I do not yet have one but I am currently looking at a few on Ebay that are standard in Sony TVs. So i guess my questions would be: Is it safe to connect a flyback transformer to it? Is it even safe to hook up 2 transformers in that manner? Would it burn it out? And what kind of Voltage could I expect out of it? Would that kind or brand work well? Any help would be appreciated, Thanks.

Since the plasma TV I found in a dumpster this month does not work (missing the power supply board), I took the boards apart for parts. Now I arrived at the screen. To my surprise it was no LCD, but a plasma screen. As I understand, every pixel has 3 miniature fluorescent tubes in it. Would it be possible to use /convert as a light fixture? (some specs: V=5.25 V, Va= 65V, Vs= 125V, max 300W when white)

I was thinking about building a homemade plasma cutter. My plan would be to use two linked microwave transformers to step up wall voltage to ~ 50,000 volts. I would use welding carbons in the end of a copper pipe, nozzle, etc, so that an arc would be generated inside of the nozzle. I would then have a PVC assembly that would take compressed air and force it past the arc, and thus generate a spray of plasma? I KNOW how regular plasma cutters work, I was just wondering about this design out of curiosity, but I know there is likely some flaw (e.g. the arc isn't drawn to the work, etc.) that I haven't thought of. Advice is appreciated. Thanks! P.S. What, if this design works, would stop me from using this to weld? i know that the plasma is too hot, i would just keep the torch a distance away from the work. Or would the air contaminate the weld? Thanks! EDIT: I know how traditional plasma cutters work. I don't want to strike an arc with the workpiece. I want to create an arc in the device and used compressed air to blow the plasma onto the work. Also, i think i could use a smaller power supply, say 7.5 KV to generate that arc, without MOT's.

I'm planning on doing a little bit of high-voltage work ( see my plasma cutter question), and I know most of the theory ( except why HV AC in power lines wants to go to Earth ground--any answers to that are welcome. I have my own theories, but...), but I have really no practical experience at all with high ( 50,000 volts) voltage, i.e. what gauge of wire to use, what gloves to wear, how to ground a metal container, etc. Any advice is welcome. Thanks!

So I have had my plasma ball for about a year now and it wasn't very clear anymore. At the top I noticed that there was some kind of coating on it after washing about 5 times with windex. The ball worked fine were there wans't coating anymore so I rubbed it all off, it was plastic and now my hands are all sparkly. Was that ok or am I risking major health problems. Also, what is it for. So also, if your plasma ball is murky this is why.

"A Florida county plans to build a facility to get rid of their landfills, generate electricity and produce construction material, all using a process called plasma gasification which vaporizes garbage at temperatures hotter than the surface of the sun. The $425 million facility expected to be built in St. Lucie County will use plasma arcs to turn garbage into gas and rock-like material. It will be the first municipal plasma waste processing facility in the united states, and the largest in the world. Expected to be completed within 2 years, the 100,000 square food facility will process 3,000 tons of waste per day. Fed not only with waste being produced currently, the facility will also begin to process the waste already in the county landfill. Estimates predict that the entire volume of the existing landfill, 4.3 million tons of trash collected since 1978, will be processed within 18 years."Read More...It almost seems too good to be true, what do you think?
