- This revolver blew my mind, and so did Mel Science. Check out their science kits at melscience.com/sBI_/ , and use the promo code Plasma50 to save 50% like a king.
Electrolytic capacitors blow up when they are pushed too hard, and because of this, can also be used as a propellant. Purely for innovation and engineering, I built a working capacitor revolver and tested its capabilities. Check out the new merch here: crowdmade.com/collections/pla...
Thank you to Justin Banks for assisting with the idea as well!

GREAT VIDEO...
Did you try with reverse voltage? Do they blow up more with the same voltage or it's the same?
Hey! I made this exact same thing except in a mortar form it’s on my channel
I really hope you make a cannon with that 8 farad capacitor!
Have you looked into using magnets as a shear pin for air cannons?
If the magnet holds back the projectile while the firing valve opens and breech pressure builds to the magnets holding strength before the projectile starts to move you get far greater velocities.
Ps, it also works for a log splitter.
Nice clean explosive build!
Hi mehdi, it's time for full bridge rectifier cannon
Thanks my friend. It’s incredibly fun to shoot. Already started ordering parts for version two!
We'd like to see you popping them by tens of thousands of volts.
Something tells me that you know a thing or two about this subject.
Is it just me or the small capacitors without relief cuts explode harder?
Maybe try multiple smaller ones like 47mf 16v x3 in parallel.
Hi Mehdi 🙋♂️
Watch out, the microswitch you use as a trigger is not suitable for the high current that flows. Eventually the contacts will weld together and cause an unexpected firing when turning the barrel to the next shot. As others commented, a better design would be to use a high voltage / high capacitance capacitor charged through a step-up regulator as energy source and to use a semiconductor switch (like a MOSFET, which can easily carry a kiloAmpere for short time) to trigger the shot. Then you only need to control the gate voltage through your trigger. Another benefit is that you can make the high current path as compact as possible, thus minimizing inductance from cabling and you can add debouncing to the trigger signal as a mechanical switch has the tendency to oscillate when closed causing intermittent contact in the first milliseconds.
You made an actual capgun! I'm so proud of you, lol.
It's a sciencefide capgun!😂 AWESOME!!!
Gamma Gun from FO4
I think it would be really funny if he ended up using stronger capacitors to store the voltage needed to make the other capacitors explode. CAPACITOR vs SLIGHTLY LOWER RATED CAPACITOR.
That's exactly what I was thinking! Get a nice hum before each shot too!
I was exactly thinking about supercaps, good amount of them will surely make a huge bang to those small caps 😎
Or you could just do what military researchers have done decades ago and just use cartridges stuff it with tungsten wool and a electrolyte then slam it with a stupid amount of current. Using polarized caps is easy and fun the play with but at the same time also really inefficient.
This was my first thought. Why not use a bigger capacitor to blow the smaller ones. You could get an air conditioner capacitor for $20 that would be WAY more than you need.
I mean this is about as efficient as black powder so I stopped watching
What about using a capacitor to build up a strong sudden voltage to explode the capacitor? Almost like a spark plug. It might be more efficient and create more power.
A buck DC-DC step up module will be needed, up to 90V (I don't know if it exists on this value, if don't, will need a small 60VA inverter and a FULL BRIDGE RECTIFIER), and a big capacitor, because it needs give a 10 amps discharge.
It merely boils a fluid that sits in between the plates.
@@brucebaxter6923 but with more power you might get it to boil faster. Getting a more violent reaction.
@@zeanyt2372
Yes.
But the possible down side could be that it splits open before all the fluid has boiled.
We want popcorn not a saucepan.
Popcorn has an upper temperature limit.
No, we don't want steam, we want plasma... This is the plasma channel... High voltage for throughput and high amperage for volume.
Electroboom is proud of you!
F that guy
His spirit animal as well.
Joergsprave too! 😂
6:39 Can we just take a second to appreciate the fact that this man found a way to turn "busting some caps" from a slang phrase to a literal description?
I was expecting this to be something more electricity-based using the fast discharging capabilities of them, but you really channeled that inner scientist in you and went for something a little more... unique.
Oh, this isn't inner scientist, this is inner-engineer. Innergineer, if you will.
"Dont try building one yourself!"
ElectroBOOM: No.
Also...
Styropyro: No.
At least watch the home made electric guitar tutorial before attempting this
I'd say "me: no." too but where i live, I'd probably end up on a list
...oops
😂
Yup. He made an alarm clock out of this concept
I can't imagine the smoke out of those things is good to breathe in
Probably about as dangerous as a real gun
Probably as good for you as the 'capacitor juice'.....
@@Debbiebabe69That orange juice tastes pretty well..
Yeah, that smoke can give you some real harsh cancer
only if you breath a lot in tho
You can connect this small capacitors to a bigger one that chargered to 400 Volts (for example). Thyristor will help in controlling high voltage. And you can use a small battery with DC-DC step-up converter.
There is a revolver somewhere, where upon pulling the trigger before it fires the cylinder is pushed into the barrel to create a better seal.. you can try that and make the barrel smaller in diameter to increase pressure which increases velocity
Pepper box revolver instead of trying to match up the barrel to the chambers?
Have you tried using smaller capacitors?
I discovered accidentally that some small electrolytic capacitors shoot their casing out very fast. I was desoldering some componets with a blowtorch and one capacitor flew so fast it left a mark on the ceiling. I have only tried exploding them by heating them externally but it should work with electricity as well. It seems that the bigger capacitors just burst at the top with a relatively low pressure but the small ones are able to hold so much pressure that the case pops out of the rubber base and shoots away. Using them would simplify the design and make it more powerful and possibly more compact
Keep the higher energy of the big ones and just seal the top so they can't vent
@@aliveandwellinisrael2507 wouldn't that risk a failure in the acrylic potentially blowing the gun up in hand?
lol, I had one 1000uf cap give me a black eye when I connected it in reverse on a slayer exciter circuit when I was little.
Older capacitors don't have those safety vents, even the larger ones. And on cheap chinese caps the vents sometimes don't work.
Having accidentally exploded many caps, I can only imagine the smell this creates! I'd also be a bit worried about the fiberglass-like dielectric being atomized and inhaled, but the end result is pretty fun!
Yeah. Silicosis is not your friend.....
@@coreyclark3877 When I was younger there was nobody to told me that magic smoke is not super healthy. Also the solder with lead is not fun.. Fortunately Iam ok. :-) Just once battery blew up in my face and I was blind like for month, I recovered from that too and can see well :D Stay safe !
Isn't this humanity in a nutshell? "This might end horribly, but at least we had fun along the way!"
@@jmenonenidulezite561 I had a little accident one time with a graphite and a UPS 12V battery, I tried a graphite lamp and when I turned it on, the 0,7 graphite just exploded on my face. I've learned that this graphites comes with a substance on it and I can't turn it on a high amp 12V battery, I have to limit the current or use a lower voltage first, to let all the smoke go away first, drying the substance of it first or it explodes, I also have a 12V high amp transformer, and if don't dry the graphite, it explodes.
yeah and the toxicity of vaporized electrolyte ...
Your ideas are revolutionary,I admire your work!
Love the project! I just had the thought that a smaller projectile would likely allow for significantly higher muzzle velocity.
Nice work Jay, that's a pretty unique way to use a capacitor. For version 2.0, I recommend trying to use the capacitors in a different way: in an electrothermal gun. They put railguns to shame, and if you build one powerful enough, you might just land a collab with your spirit animal over on Demolition Ranch, lol! Keep it up man!
I thought up of a similar idea the past year where you have a electro thermal-chemical gun using a poisoned high explosive (essentially a high explosive with heavy non-explosive additives, making a product that can be heated, burned, melted and molded into a casing surrounding a projectile but not be triggered until a very strong electric pulse discharges into a plasma cartridge and releases a lot of plasma/ultraviolet radiation into the propellant case. This helps the problem with caseless ammunition by using propellant that can’t explode chemically unless subjected to pulses of plasma or radiation, which makes combustion of it more efficient as well. Also to help would be to take the waste heat from the propellant to run a stirling cycle which taps into the heat from the breechblock to recharge the battery used in the weapon. Which would make the system capable of outperforming conventional guns while being inherently safer in being electric and easier to manufacture.
@@topsecret1837 That just sounds like you wanna use TNT and build your own exploding bridge wire detonator in pistol shape.
Thanks LC! I'll have to research those further, and definitely am in the spirit of innovation.
@@xxxm981
Oh no, it’s really different than that:
en.m.wikipedia.org/wiki/Electrothermal-chemical_technology
@@xxxm981
Also, TNT would be too dangerous. Smokeless powders and gunpowder in general belong to the family of low explosives, where their detonation velocity and reduced brisance prevent the barrel from shattering, which would be deadly and unsafe to the user.
High explosives are otherwise completely unused for those exact reasons. The way I had in mind to approach the problem would be to take a high explosive and weaken it to a point where it’s still more energy dense than double or triple base powders but weakened enough to prevent the brisance and detonation velocity from exceeding the pressures that normal barrels are capable of withstanding, thereby increasing muzzle velocity but also to make the propellant so difficult to detonate only ETC technology would be capable of igniting it, period, to a point where the casings can be 3D printed and injection molded into forms that can alter muzzle velocity and projectile size while keeping the case size the same for all calibers.
Maybe what you could do instead of using a capacitor as the propellant, design a plastic container with a heating element inside a few drops of water. The 60VDC would very quickly boil the water and burst open the container. Make it do this directionally so all the explosive force is directed out the barrel. Anyways great video as always, love the demo ranch hat
If you ever feel like revisiting this you could probably use the capacitors to shoot lightning and control it with HHO gas which might also clean the chamber. xD good luck
if you take this idea and even maybe make a vod with it, do some background research into charged water explosions/implosions and into EVO's or EV's; and you will also want to look into suspending water with zero-point energy; the zpe charged water releases lots of energy when come into contact with high voltage electric discharge. Have fun! Love your channel!
I had a similar idea.
Sparkplug rifle.
It uses a sparkplug instead of a bolt and caseless ammunition.
It can be made with basic materials. The chamber is almost completely sealed due to no ejection port or opening bore, allowing for maximum compression.
To fire: moving the lever action racks a round and also, using a set of gears and a clutch, spins a small generator on the side. It spins like one of those rev-and-go cars, where it keeps spinning after the lever has been returned to starting position. When the trigger is pressed, it closes a switch to the capacitor, and the sparkplug in the chamber fires off, igniting the primer and sending the bullet down the barrel. If ammo is out and youre cornered, you can overcharge the cap for a pseudo grenade
You don't get consistent firing with a quick low energy spark. You could use a semi cw high voltage source (Which probably wouldn't be great since both black powder and gunpowder leaves a bit of sot which would short the electrodes that ignite the primer). The other option is to use a heating wire. Either way, It sounds like a cool project and i wish you the best of luck if you decide to create it :)
How fun! Although, I have to wonder if just vaporizing salt water with a huge current wouldn't be more... economically sustainable lol. I guess those caps are cheaper than some rounds though. Cool project!
Probably corrosion would be the reason that would be hard to make work not because it wouldn't work but vaporizing salt water would rust literally everything around the gun
@@kennydoggins1712 Point taken. Sodium chloride isn't the only electrolyte in the world though. You just need the water to have a slightly higher resistance than the rest of the circuit and it will get hot very quickly. That's what's happening inside the capacitor after all. The electrolyte makes the explosion. Maybe baking soda?
@@DFPercush fair enough but you'd have to tell me you obviously know more about this than I do, I would assume that anything that produces excess humidity wouldn't be good even if it wasn't infused with salt
@@kennydoggins1712
This entire video revolves around getting the guts of the capacitor to get hot enough to vaporize the liquid inside of them. That liquid is salt water. Its always salt water of some variety because that's what an electrolyte is, saltwater. There is no need to use capacitors. Any sealed metal can (the shell of the caps) with liquid inside of it (electrolytes), will explode with heat applied.
This video and every video that I've ever seen on this channel are disingenuous bullshit. This gun in this video is *NOT* electrically powered, its electrically triggered. Its a steam powered projectile....something that's been around for like 200 years or more. Just like his "Star in a Jar" video - a design he ripped off as original work, which has been around since the 50's and was invented by the inventor of Television. Or his ion thruster idea, also ripped off from the 50s or 60s and fully developed already.
Theres nothing inherently wrong with redoing old inventions, but he doesn't credit the inventors or the history. You can even find videos of people blowing up capacitors like these for fun on reddit from years back.
StyroPyro does real original work for example.
@@wilurbean Tiny issue with your claim: what, in this system, is _powering_ the conversion of the electrolyte to steam, hmm?
Yoo this video was fantastic. Great job ! Excited for version 2.0
The final 20v test at 5:06 had some really interesting oscillatory motion
You can use a simple booster circuit (step up module) to achieve high voltage. If you double the voltage (120V) the all thing will be very interesting.
Yes its good idea
this is literally a steampunk revolver lol. it uses literal steam as the propellent, which is awesome. i've seen a few different designs that use a boiling fluid (usually water) as propellent, and they are always interesting
Technically aren't all CO2 based airguns doing that?
Love the idea, I was working on a small handheld mac but that is now on the back burner.
this GIVES ME SO MANY IDEAS! i love it thank you so much for this
i subbed and rung the bell thanks
I like 6.3V 100uF ones, their can is usually not designed to rupture, there is no cross on the top. Instead, the pressure builds up until the can pops off the rubber base, quite energetically.
agreed, you can also add epoxy to defeat the pressure relief valve on the bigger ones - the cap provides its own bullet.
All those details are so simple yet so perfectly thought through. Well done!
Thank you!
Definitely not the propulsion system i had been expecting. At the end of the day that's all a modern bullet is, a controlled explosion used to push a projectile, but i was expecting the old standby of magnets pulling the round. Nice twist 👍
If you use a voltage multiplier circuit you can increase the voltage from 60 to possibly closer to the 90 volt mark. Depending upon the amperage of the battery and the amps needed to overload the capacitor.
That looks like a lot of fun! Since voltage is directly related to velocity, I wonder how it would do if you used a boost module? Or a small high voltage power supply, like from one of your battery powered Tesla coils. Would there still be enough current?
Great video!
Or used a capacitor bank to blow up the capacitors!
You need quite a bit of current as well to blow up caps - so the velocity will go up with the voltage, but once the voltage get too high, the velocity will go down again due to lack of current capacity. So it will be a certain voltage that gives optimum result. Those high voltage sources that power tesla coils and stuff will not work, since their current output is only like a few milliamps. But, the more input power you have, the higher the optimum voltage will be. The voltage rating on the capacitor also matters - which will probably need to be exceeded by at least 2-3 times (lower voltage capacitors will probably work better with less voltage and more current - and higher voltage ones with higher voltage, less current). They can also be blown up by feeding them with the wrong polarity - in that case, quite low voltage (just about 5-10 V is often enough) and high current, probably gives the best result.
Thanks Nigel, yeah the voltage definitely has an impact, but i'm worried that boost converters would not provide enough steady current to explode the caps. However, 20 amps for half a second should not be too hard to manage.... The high voltage supplies from the tesla coils indeed may lack enough current to really boil the electrolyte inside the capacitor. I haven't tried it, admittedly though.
I was thinking to just use an automotive or motorcycle ignition coil, store it in a high voltage capacitor and pop caps at tens of thousands of volts.
@@PlasmaChannel Can u use supercaps for steady current?
Awesome video, did you experiment with reverse polarity and opted for higher voltage, during my apprenticeship days we added electrolytic capacitors in reverse to blow the terminal boxes off the wall when our tutor turned the psu on during practicals 🤣 brought back some fond memories 👍
Strangely, I did try reverse polarity. Found it slowed the barrel speed drastically, and lead to irregular explosions that were unpredictable in terms of time. Strange. So, I stuck to normal polarity.
You could use a simple flash circuit from a throw away camera to create a massive voltage to really go large, plus they run from a very small battery pack (think two AA’s)
Thank you for the educational and entertaining information
amazing video thanks Jay. I'm sure you have noticed but just in case the video didn't show up anywhere (subscriptions page, home page, or your videos page) I only found it by chance in one of your playlists, I hope your able to sort the issue out as it was a great video and that it didn't cause any problems with your sponsor. Good luck sorting it out, and hope you had a good day.
Thanks Jonas, strange that you somehow saw this before anyone else. I had it on private / unlisted. You got lucky!
That is really a smoking gun! I suffered when you were destroying all those capacitors but watching your creativity and passion for experiments was worth it :)
A small hint: you can use a high voltage capacitor as energy storage and charge it between shots with a step-up converter, then you will not be limited to battery voltage. It should be capable of storing much bigger charge (Q = C x V) than each "propellant cap." of course.
The smoke effect really made me happy as well. It was unexpected. Thanks for the input!
When I was in High School {1964--1969) we built a pingpong launcher that vaporized a peace of nichrome wire in a tube with high voltage, we could get the balls to go 100 ft.
They say great minds think alike. I had this idea thirty years ago. Just never ran with it fella. Ams so impressed with you dedication and work ethics. WINNER "JAY" PERIOD!!!!!!!!!!!!
We did this in the late 60s or early 70s. Back then caps didn't have the little X engraved in the end so the entire case would shoot off like a bullet. We converted a cap gun and used batteries. They were pretty dangerous though.
@@USA__2023 Excellent to hear Clay. Just amazing what a determined mind and resourcefulness can make happen.
This is something I made in the late 60s that took off and made billion plus of dollars for the lucky guy who made it happen while I just did not follow through. The swimming pool creepy crawler which cleaned the pool water surfaces and especially the bottom while the filter was used to clean the water. Like I earlier, great minds think alike.
Now I want to see you run it but instead of a direct connection to the battery you have a 2nd capacitor that doesn’t blow up but stores the charge used to blow the other capacitors up.
If you want a higher velocity try lengthening the barrel. A longer barrel will give the projectile more time to accelerate thus increasing the muzzle velocity.
I want to see v2! I really liked it and i am wondering if you could use one of those small 10v 16uf caps and use their one body as a bullet?
That would be very effective!
I've been doing HVAC for maybe 20 years and it's awesome to see most of the things you dig into require materials and know-how I've been exposed to. Between the vacuum pump for you star in a jar to the capacity a capacitor has to ssssplooooode! Glad I found your channel.
Get some small non-vented capacitors, when connected wrong, their case becomes a projectile.
That's not a bad idea. I'll look into that. Thanks.
@@PlasmaChannel No problem, I learned that the hard way.
could also glue the top of a vented one to force it to blow from the bottom.
@@liquidmagma0 I don't think that would work, there is so much force that builds up that every glue would break.
@@filenotfound__3871 maybe soldering the top is enough.
Super cool! To boost the voltage, maybe use an inductor with one side to + and the other side with a a mosfet to ground. Let ~10 amps build up in the inductor, then disconnect the mosfet. Voltage should spike very high, depending on how large your inductor is, and how small your cap is.
Of course. It's really cool ! Maybe, maybe. Look here:

Just use an old CRT TV horizontal deflection circuit - the old flyback type …
Love this guy
I hoep you pick up this project again and continue improving the design. This was great!
Someone FINALLY built one of these things 🙂
Though I envisioned a chaingun type using tapes of capacitors to do the same....
Still cool tho and I'm only 28 seconds in (so you could've acheived a short too, but I avoid those)
Hey this makes me think of two projects for you. Both of them by the same inventor, Edwin Grey. Edwin invented a motor that used high voltage capacitive discharge to make the coils impulse and rotate. The motor coil with its nominal impedance looks as a very low impedance compared to a high voltage capacitor so the capacitor instantly dumps and you get an intense magnetic pulse. But he started by pulsing magnets this way and making them jump with great energy when the capacitor discharges. You should put that into your gun. And yes that's plasma related because it uses a spark gap to switch the dump cycle when the capacitor voltage reaches High Enough during charging. The second project is the motor itself.
We used to wire them up back wards and connect them up to the bench power supply, then wire them in to a colleagues workbench draw, turn on the psu and bam instant smoked documents. The bigger caps were always the best.
Very cool! I would really like to see something on a slightly larger scale, like a potato cannon... that would be epic!
Too cool my friend! Would love to see you try a battery powered Ion Lifter that could fly around with a remote! Thanks for keeping the 4th State Alive! Plasma is King! ✌👽
Shhhhh....dont give away my secrets..... :P
You showed testing overvolting the capacitors, I wonder if doing this + reversing the polarity could lead to greater velocity?
That's what is shocking. Off camera, I did test reverse polarity overvoltage. Honestly, it reduced velocity and drastically slowed down the reliability of the explosion.
Nice proof of concept
Sweet I conceived that idea years ago for a shotgun. A scientist at Honeywell labs retired and built it. Love to see it.
Hmm. I think the performance ceiling of this architecture is actually pretty high. It's basically an electrothermal propelled "launcher". As long as you have enough electrical energy delivered within the relevant few hundred microseconds, and the breech and barrel can take the pressure, and the seals don't blow out, etc etc, the molecular weight of the actual propellant is low (mostly water), so the achievable velocity should be pretty high. The capacitor casing should even help with the sealing. If you go to the high end you need basically all the features of a conventional propellant "launcher" though. Don't blow up anything in your face.
So basically like any other enclosed bore cannon. Because that's what it is.
You try so hard - So _very_ hard to sound smart.
Great Job figuring things out..I remember using a battery and a solenoid switch to fire a semi auto just as fast as a auto rifle...Would like to make a coil or Rail gun with real POWER...Have any ideas? Thanks & keep up the great work.. P/S...You could also make it fire with a 1`.5 volt battery with a small high voltage inverter transformer & maybe a dc to dc converter... be great to make one that would shoot maybe bb's or pellets..A Poor Mans Ray Gun are fun also, & POWERFUL..Just need an old microwave oven and take the magnetron & Capacitor out & I think it also needs 1 more cap. and a diode...You can find it for free on Internet Archives...More Powerful than any Burning Laser... Thanks again...
The ATF is interested.
Sweet, A practical use for factory smoke.
Really want to see the 2.0 version great idea
If you want your "projectiles" to fly straight, I'd recommend giving them round noses. You might be able to find arrowheads that are the right shaft size to work.
Yeah, the projectiles really were pretty basic on this one.
I guess you could say its a cap gun
would love to see a second version that also rotates the barrel when the trigger is pulled like a real revolver!
Some time ago, Remington made a variant of their R700 called the EtronX. It operates under the same principle and would be a good source to get inspiration from. Ian at Forgotten Weapons has a really good video on it.
I see what you did there, you made a cap gun! Not in the conventional sense.
Underrated comment here!
Yeah, just not kid friendly ;)
nice pun
If you want the projectile to flt faster you can cut small holes for the air to escape.
Many guns have this feature to allow for the muzzle flash and noise to be lessened.
However it might help you with the vacuum that the projectile creates.
This is some quality filming and content
I wonder what voltage the upper limit would be I could imagine if you chained batteries together like styro pyro did recently you could get some pretty insane velocity.
Ok…you got me, new sub. Nice build, thank you for sharing.
cool idea, wonder what sorta upper limit these would have , could use a large high voltage capacitor/charging circuit might be a little dangerous tho :)
You could use a DC-DC converter to ramp up the voltage too, or use the mains power with a ballast sending 120V ac (or 240V) directly to the capacitor.
I once connected a bad 100uF 50V capacitor to 100V 50Hz on a DIY psu that also delivers 115V and 230V ac up to +1000W.
The bang was as loud as a magnum gun shot.
Electronics are fun as hell.
Been into that since 1998 and work as an electrician.😄
Did you wire the caps up straight or reverse? Could always test which way gives the greatest muzzle velocity ;)
This is so sick!!!
Cool Idea! I blew up _a lot_ of Capacitors in my "Career" but this is... the most useful Method! 😁
Hey Jay nice video....and i suggest you that you can use a voltage booster circuit using some transistors , coils and capacitors to massive boost the voltage of power supply . You can use lithium ion batteries connected in parallel so that a lot more current can be provided . This is beneficial cause the voltage boosts up while current remaining constant and you will get the full backup . I would recommend you to build voltage booster with transformer .
Love this , great work make memories and give a young man guidance in a positive way. ;)
Could you use a battery to charge up a large capacitor then use that to blow the capacitors? If the fumes are flammable then you could ignite that with a simple spark using the battery to fire a normal projectile.
Thank you science
Could you encase the capacitor in expoxy of varying thicknesses for more pressure build up ?
thank you man,you are a legend
Sure. It's really cool . Look here:

Where tf have u been my whole life!?? This is AWESOME SAUCE! Dude your channeling is on point !
Ya'll might like to know that SMD tantalum caps make very nice sugar rocket ignitors. 6.3v 1-22uF (depending on ya rocket size), reverse polarity on a 12v bat, goes great, far more reliable than the steel wool we were using.
I love the theory, and it's an amazingly creative use for them. It's just unfortunate that'll never be practical
That is such a fantastic video Jay!
Every parent should be ordering a package from mel science once a month wtf, what a great way to engage , educate and spend your time with your kids
If you wanted to get a higher voltage from the battery, you could always get a boost converter to up the voltage.
We did this in the late 60s or early 70s. Back then caps didn't have the little X engraved in the end so the entire case would shoot off like a bullet. We converted a cap gun and used batteries. They were pretty dangerous though.
Years later in the early 90s I was working on a nurse call system at a nursing home.. It had a bad filter cap on the power supply and I grabbed the wrong voltage cap. :(. When i powered it up that sucker popped big time. Filled a room about 10 X 15 with so much smoke you couldn't see. The case of the cap hit a secretary in the thigh and gave her a huge black and blue welt. Wasn't one of my best days :)
the split helps break the vacuum pull. this is interesting
Ok you strange science person 😁 It took a couple of videos, but you have earned another subscription! I look forward to the realization of your crazy ideas!
Next up add a voltage multiplier like one out of a stun gun. Around 45kv-120kv range should do it.
Some types of capacitors have ventilation built into the the lead side, I’m sure those paired with a capacitor discharge bank like what other commenters mentioned, would give you a situation where the capacitor it self could be the projectile. I used to mess around with a microwave transformer connected to a wood pole and would touch capacitors on a random circuit with the arcing end and some of them were powerful enough to blow through my drywall ceiling, kinda sounds like a fun death contraption to make
If you're going to use copper then you can solder one leg to the tube, with a common central tap. Then you need only activate one leg, which will make the contact easier overall, I would have thought. However, a metal item travelling down a copper tube might well create eddy currents and slow down your projectile, so you may be better off with a plastic bullet.
Nice! Watching from Brazil.
You can build a relatively simple circuit to supply higher voltages with the current needed in short bursts, see "charge pump".
Try using a capacitor HV charging circuit and a much bigger capacitor to deliver the amps and voltage to the "explosive" small capacitor.
You can get a circuit that will charge a big capacitor to 300V from a AA battery in disposable cameras. Overall a nice concept
You can see that at your lower voltage the projectile actually stays in the barrel and then gets sucked back in. Maybe some light rifling on the inside of the barrel could help with that vacuum and add some spin
The funniest thing in this video is that the deleted text is the most replayed part of the video. 😁
Yup... Fun times at school - we connected such caps to the mains :-O The case was flying across the room :-)
As someone who's very interested in firearm design this could be a concept that would be useful The only issue is it probably wouldn't be good in the military setting because of how expensive capacitors can be along with the costs of producing power to keep the batteries running and in its current form it produces slightly less power than the average BB gun but it is a really cool idea and with time and money could be expanded into something that would be useful for target shooting or maybe hunting if it proves itself to be reliable You should try to talk to people like Brandon Herrera who design guns and build them and have shops because they can teach you a lot about pressure and tolerances and how to make a more efficient and safe pistol
Amazing prototype concept..
Almost a General Electric correlation
