- Mk2 coil Gun:
10 Optically Triggered Stages,
Runs off any DC Voltage Between 12-45V (tested) / Upto 200V (untested).
Fully Automatic Reloading system capable of delivering more than 720 Rounds per minute (12 rounds per second) to the 1st Stage.
The first stage has the longest "on time" (highest duty cycle) of all the coils, therefore the 1st stage suffers a little after a good 10 seconds of continuous Automatic operation.
By this point the gun would have fired over 120 Rounds and would need refilling anyway.
This project was more about high speed reloading than high power but it's still a large improvement in both power output and efficiency over the 6-Stage MK1.
Thanks For Watching!
"It costs 36 dollars to fire this weapon...for twelve seconds."
It should be around 4.87 USD for 12 seconds.
720 rounds per minute / 60 seconds in a minute = 12 rounds per second x 12 seconds = 144 coins x 2p each = £2.88 x 1.69 (GBP to USD exchange rate) = $4.87 Total.
The gun would probably overheat if i done $36 worth in one go ;-)
Yeah you're correct I think I got my order of operations mixed up. The gun is really cool!
Thanks ;-)
SupremeGoatOverlord better get your math right heavy.
drathkiller6 There are some who could outsmart me... Maybe, maybe, but I have yet to meet one person who could outsmart penny.
Insert a coins to continue
Best comment 😎
VERY, very...cool man. Very cool! :)
should rename too "How to seriously piss off home invader"
Finally a good use for pennies
what if the home intruder just holds up their open wallet? oh no

could make a paper plane gun that uses £5 notes. that'd be expensive though!
Make a $400,000 in 12 seconds model.
leerman22 That would be amazing, I'd only be able to demonstrate a few mS of operation though :-D
leerman22 I scrolled down hoping no one made that reference so I could be the first

Cool! Casino's should install these in their slot machines! XD
'Money' can kill a man.
This could be used as a diversionary weapon against Reimu.
She'll chase after the coins.
Wolah dude. I will redesign it
It's like the world's angriest slot machine dispenser.
I use a similar system to deliver money to buskers. But mine is more powerfull.
This is perfect for the strip club.j/k
Thanks for sharing
Jae Shon lol. for that i think you need the paper plane gun, load it with £20s and your good to go!
LOL
Yeah now I dont have to waste energy throwing my pre 1983 copper pennies as hard as I can anymore.
someone get me 5 rolls of pennies QUICK!
that didnt sound right didnt it?
With "Pulse-Rated" Capacitors and an Incredible power supply in the 20kW Region you may be able to make a pretty good capacitor driven coil gun with similar RPM. I would still think the capacitors would heat up over time... Not before the enamel melts off the windings though!
Love the flat coil/projectile idea!
I need that for the next time my son asks for money
Haha. I like your thinking ;-)
Awesome!
But couldn't you increase the friction on the right or left side of the channel to get some spin to the coins (this should stabilize their flight ;) ? I think of foam rubber or something like that...
Another good suggestion ;-). probably the simplest and most reliable solution +1
Whenever I think NASA has been weak in it's development, or PC's haven't come far enough, or video games have plateaued disappointingly; I come to coilgun/railgun videos. Ten plus years of them and they're still low powered underperforming novelties that are so poorly made and so not fit for purpose they're a hoot!
It's only for fun and given the weight of the projectile, there is a fair amount of kinetic energy there. Railguns are more powerful than gunpowder now aren't they? they just require a warehouse of capacitors and power supply lol
That looks great! I'd like to get mine to do full auto runs like that. Is stage 9 bigger than the rest of the other stages?
Hello, would it be possible to make it with super capacitors that load up and fire one really fast round? And could u change the ammo to 4,5mm or 5,5mm diabolo? Or maybe self defense caliber 50 or 68? Im interested in an build guide of this gun!
Hey, Yeah that would be possible. in fact, they tend to be easier to build as the reloading mechanism can be nice and slow 😁
Really impressive! Nice work :D
Could I make a question? The coins seem unstable in flight. Do you have tried to make them spinning (with a friction on one side for example)?
Thanks. Yes they are unstable. Friction on one side could have helped but would also result in the coin leaving the barrell slower.
Interesting question and idea! But I don't know about the Magnus effect at this size. Giving the coins a spin could cause them to deflect either up or down, depending on the direction of the spin, during the flight. If I had a coil gun like this, I would definitely try the spin idea to see how it turns out!
No pun intended. lol
Can you tell me, how to make it?
Has a lot of potential but shooting pennies at someone isn't going to exactly stop them in their tracks. Good effort, though.
Not Bad, Reminds me of Playing with Match Box Cars with not enough track,
50 cars later gotta go and pick em all up lol
need to build a robot to collect them all and place them back in the gun ;-)
More Vortage and supercaps!
Thank you everyone for getting this to 500,000 Views!
I also made a 3D Printed Gun here:

What is the Basics you learned to do this mechanical engineering, electronic engineering, ??????
I haven't studied electronics at all. I'm an electrician but you don't really touch electronics. Everything i know is google ;-)
Wow, I actually thought You are an electronics guy.. it so happens that I'm an electrician too, and i think i have a solution to your problem of running too much current through electronics components in order to power up the coils.. If U're interested drop me a line on my email on google account:
gustarballs1983
at least I'm interested in having all the schematics after You'd adapt my idea..
Congratulations...............take my like.
I wonder if you could add some resistance to one side of the track to get the coins to spin on exit?
cant legally manufacture new machine guns. builds full auto rail gun
Really nice work! The freewheeling diode configuration increases the time during which the magnetic field collapses substantially though. From my experience, I suppose you could increase your muzzle velocity if using a full-bridge for each coil (or two FETs and two diodes).
A full bridge.. I'd never considered this before. What would you have the full bridge do?
Most of what follows you already know probably. You have big inductors, probably a few hundred of uHs? That means it takes time for them to go up to peak current. The magnetic field corresponds directly to the current through the coil. With a freewheeling diode it takes about the same time to discharge as it took to charge the coil. That limits the mean maxium force you can apply to the projectile. A n-channel MOSFET full-bridge will use two opposite high side / low side MOSFETs to turn the current ON and when you turn off the coil will discharge through the body diodes of the other two MOSFETs into the battery (two of these FETs are disabled by shorting gate to source) The coil discharge time will be much lower, so the current can stay higher for a longer time. Dificult to explain in writing. Don't take my word for it you can easily simulate this in Multisim or Pspice etc. Good luck .
I get what you are saying, would be interesting to give a go. I've been unable to work on any projects for the last 14 months or so as i'm in the process of building a new work area, once its done i'll be sure to try it! Thanks. Last thing i was working on is a capacitor bank capable of delivering 1.6Mw, can't wait to get back to working on it
TomTechTod can you tell me from where i can get a schematic of this coilgun pls
Arjun Gharti Hi, The circuits been revised since this was built, Here's the new one m.facebook.com/hv.discharge/posts/ms.c.eJwzNLIwtTS3NDQ0sTA0MLQw1zOECBgZWBiaGJsaGgIActkGuQ~-~-.bps.a.102964963111614.5842.100001943323580/?photo_id=1285979208143511&mds=%2Fphotos%2Fviewer%2F%3Fphotoset_token%3Dms.c.eJwzNLIwtTS3NDQ0sTA0MLQw1zOECBgZWBiaGJsaGgIActkGuQ~-~-.bps.a.102964963111614.5842.100001943323580%26photo%3D1285979208143511%26profileid%3D100001943323580%26source%3D48%26_ft_%3Dtop_level_post_id.1285979208143511%253Acta_types.1%26__tn__%3DEH-R%26cached_data%3Dfalse%26ftid%3D&mdf=1

My name is heavy weapons guy... and this is my weapon. It fires 2 cent coins. 720 rounds per minute. It costs 1440 pence to fire this gun for one minute. AHAHAHAHAHA
Don’t use pennies...get steel or copper BB’s (~3mm) or larger pellets (6-8mm).
You’d have to develop a feeding system to funnel the spheres reliably.
Interesting comment as the Mk5 which i started about 4 years ago was going to use BBs.. around 10mm iirc. however other commitments have consistently got in the way! I hope to get back to it one day 👌
This would be interesting to see with steel core rounds of various size
terraria coin gun be like:
Lmao 1 penny rounds Genius ,Genius ,Genius from Mr.deeds lol F low voltage i will scale one of these up to out do a automatic m4 bigger projectiles of course & huge capacitors are needed also.
Milky Way Cruise Beatz Would be amazing! I have a huge project atm (fixing an abused house) but when it's done i'll have a dedicated workspace and upscaling and the use of bolts instead is definately on the cards!
Rogue Electron i can imagine an invention that would go perfect with a gun like this a electromagnetic pulse motor that is in a backpack like a flamethrower will charge the rifle non stop, since the electricity would be the new gun powder as long as you have a lot of projectiles you will never run out of juice. Check out my over unity series you might like it.... My two favorite inventors on the diary series are Doug Konzen & Paul Pantone & happy for you glad to know your gonna have a bigger work space to invent.
Thanks :-). I've studied so many "overunity" devices and have yet to find one that isn't fundamentally flawed. Do they have real proof that they work? the amount of videos where test equipment is setup wrong etc and provides false/ inaccurate readings is incredible. If such a thing did exist, it would be amazing!
Or a magic power plant thats powered by plastics. solve the worlds energy crisis and plastic problems in one hit!
Homeless people beware, your change is coming.
David Gerstner This is not the change they were waiting for.
I suddenly crave hazelnut and chocolate...
Awesome! !!! 😉
thanks for sharing'
👍THUMBS UP👍
AWESOME!!!!
Tim Taylor demands... MORE POWER!
That's a good idea. The coin gun works well on its side but i prefer the look of it laying down, its also easier to load.

Very Cool indeed. 1:58 Rude Wake up in the middle of night! Boooosh!
So if you shoot a5 dollar bill, will it do more damage?
Thanks, I like the neatness of your Gun, I may make a conventional round bar projectile version of this gun in a few months :-).
Well noticed! stage 9 has 3x the number of turns, it's on there as sort of an extra experiment thing for the future, should i decide to build a Mk3... or incase i get bored lol.
Wish you’d share build specs. I want to build one! Have anything for us?
Sorry for the slow reply. I sure do! If you find the Mk4 video and see the description, There's a link or two in there! 😁
Wow thats impressive! I'm now interested in trying to make a low powered one just to try out coilguns (since my Railgun i made didnt do so well).
I was wondering how did you just have the power supply running to everything? (series?, parallel?) and do you have a schematic of actually your Mk1 version? just something basic i could try out?
Thank you. All of the Coils/ Stages Are in parallel With a FET for each coil.
The control boards are mounted to the side/ underside of the gun for cosmetic reasons. The Schematic for the MK1 is actually the same as the MK2: www.hvdischarge.co.uk/gallery/MK2-Coin-Gun/Optical%20Coil%20Gun%20Gate%20Trigger.jpeg.
All that's changed is the power rating of the coils, some optimisation of sensors and a build in debugging tool. Which is on a private video and can be seen here: MK2 Coin Gun - Status Indicator/ Debugging Tool
How was it made?
I mean step by step?
That's not a coil gun, it's a COIN gun 😂 😂
this is called The CCG, Coil Coin Gun.
That gun looks expensive to fire 720 pennies per min = $7.20 per min to fire it il stick to firing nails from mine
***** It costs a lot more than $7.20 per minute! It's firing 2 pence coins. 720 x 2p = £14.40 per minute, which is $21.78 per minute! "using GBP to USD exchange rate on google"If you was to then pick them up and re use them, it would cost nothing ;-)I think 2p a shot is rather cheap. The next gun will be using custom made ammo and is likely to cost around 20p or more per shot!
Why don't you design the next one to fire nails or ball bearings it will be a lot cheaper
And to make it portable you could disassemble laptop batteries and use the Li-ion cells to make a 56V battery much lighter and smaller then car batteries then you can shoot rats with it lol
I wouldn't use Li-Po batteries they tend to explode and catch fire randomly
Li-ion or LiFePO4 is a lot safer with similar characteristics
I've never used Li-Po's before but i am already scared of them. They have a bad reputation i know :-/. spent too much money on them to not use them lol!
Lol I recommend you be very careful with how many amps you pull from them also add a temperature sensor in the battery housing and don't drop them as overloading and dropping and overheating and overcharging are the main causes of explosive Li-Po battery failure
Li-ion and LiFePO4 generally don't explode or catch fire when overloaded dropped overheated or overcharged they just internally short out heat up and die rarely they will catch fire but I have never had one explode either way be careful with Li-Po batteries
Is that issued to angry Bus drivers?
HERE YOUR CHANGE
Realy nice, made me think about my own coil gun that I'm gonna start.
Can you make the blueprints public
it costs 400 thousand dollars to fire this weapon....for 12 seconds
I was looking for ideas for my physics project ( I think I found what I am going to do!)
why only show off when you can also teach others?
hmm i wonder how effective it would be if u put a ninja star in there or small circular saw
scorpmk I was going to try that a while back but the gun walls are only plastic so it would probably wreck itself after a while. Any metal used would have an effect on the projectile speed.
You should make a six tube drum mag, add a stock, and label it as a machine gun
I love Ferrero Rocher!
Up I'm thinking of building something similar on a land drone design however I have the main issue of not knowing of how connecting the optical triggers work
Can u please explain the configuration of the optical triggers
The optical trigger is just an IR LED and IR Photo-diode pointing towards each other. The LED is constantly powered and when an object interrupts the beam the voltage across the Photo-diode changes. This change in voltage is detected by an op-amp used as a comparator and the output is then turned on.
Once the projectile has passed the optical trigger, the output turns back off allowing the projectile to pass.
If like, riot police used something like this but with say...
a car battery, then this would be really effective
Or maybe a Gauss-Tank...
Chassan Blubman Also a different projectile to hold more kinetic energy. Maybe a coil with a smaller diameter as it wraps around in a circle.
Yeah! That would be extremely effective!
like shooting car batteries in the crowd ...
The meter man is about to have a bad day...
It's good to feed the parking meter!
Seems to me like bearing balls would be an effective and cheap ammunition for a coil gun.
It's funny you should say that. Some arrived yesterday for testing :-)
+Rogue-Electron "You were looking for money? Too bad, i only have change"
Very cool! I'm going to start a small project with my son soon with the magnet and battery motor, and came across this video. What a machine! And in response to an earlier post, I would like to see the Mk3 boast more power than rounds per second, but I would watch either. /nod
Thanks For your input, MK3 is already in the design phase! "Watch this space" ;-)
It's not a coil gun, it's coiN gun :)
where can i get the project for build this? i'm interested!
Hi, sorry but there isn't a breakdown or tutorial to build this gun but i can offer you the schematic for the electronics side. It'll just be up to you to design the mechanical parts :-) facebook.com/photo.php?fbid=1285979208143511&set=pb.100001943323580.-2207520000.1517169756.&type=3&theater
Hey another thought about APPLICATIONS! What about using coil or rail gun technology to launch PEOPLE into the sky? The rate of acceleration could actually be controlled unlike shooting someone out of a cannon kind of thing...so these guys that fly with their wing suits? You could have a business all day long one flyer launched every 30 seconds for $30...do the math on THAT money! Also how about launching rental glider planes one every minute all day long? Can you picture this long line of gliders flying single file on one hour scenic flights? the gliders could be controlled via remote control and yet allow the renting "pilots" to make limited deviations to experience actually flying a plane with no formal training! HOW MUCH would people PAY?? My guess? a couple hundred MINIMUM....a rental company could have the planes built in china or somewhere and get the costs down to obscenely cheap per plane...could have a huge fleet of things! No engines so maintenance is just cable and pivot point lubrication...keep the batteries charged...might have to keep powered emergency rescue planes in the air at all times that are engineered somehow to dock with glider whose electronics failed and either effect emergency repairs IN FLIGHT or else remove the renter and somehow safely down the damaged bird ...or else not and just let everyone take their chances and sign their waivers...hell have like the ultralights where the whole plane can parachute down? Maybe jettison the wings via release levers first...of course every glider would be in radio contact ...I WANT TO GO RENT ONE RIGHT NOW!!
Tilting will also decrease in-barrel friction and you can use a screw-on pipe capped at the other end with a spring inside to push the stack of coins in the feeder, similar to the vertical one in the video (gravity feeder)... Or you can use an airsoft aeg and just adapt the multistage on the aluminium inner barrel, using 6 mm steel BB (bearings balls)! (OoO)
You need to put a weight on top of the money to force it down faster.
+Wolv A tiny magnet on the underside of the barrel works perfectly
Your problem lays not in electronic components taking to much juice, but
rather in the design of coils themselfs. Passing the current directly
is sort of bruteforce and could be bypassed if You are further
interested in what i have in mind drop me a line at my email. my google
account is:
gustarballs1983
the domain i think is obvious but i won't post it here so i don't get
flodded with spam..
You'll need to use what i developed and call a magnetic field augmenter
(or magnetic field amplifier). It's designed in such a way that magnetic
field augment it's only suitable for coilgun application as it gives a
huge spike and then it quickly goes down to 0.. the only limitation on
the current in my design of the coils is the isolation on the wire the
coil is made of, or that the wire might melt beecause it's too thin in
compare to amount of current passing through it. electronics however
would be totaly unharmed in this design as it would only show the way
for the huge current to go, and it would not pass through the electronic
components. basically it's sort of like how energo-electronics works
in industrial power stations, it controls evrything however is not in
contact with the main current flow because it would hilariously fail..
Eighter way I'm waiting if You are interested in fair exchange of ideas
and brainstorming
Ok so you know. Thanks. Just trying to help. Looks like most of your videos still show the web address though. Good luck and thanks for the great videos!
MRrwmac Thanks for pointing that out. I've been trying to cut the end of the video's using youtube but when i try to do that youtube starts uploading the cut version as a new video :-/.
Why not make darts for extra ap
And no quarter was given.
Gun safe! Do not shoot by too close range. Neither use your hand outside by front of muzzle.
"hand testing" just has to be done, You won't do it again ;-). i wouldn't recommend doing it with a conventional coilgun that's firing bolts though.
HVdischarge I'm sorry. You lost me :( What do you mean by "You won't do it again"?
HVdischarge I gotcha. I was Boy Scout and was leader aid of trooper. I understand that.
Looks impressive!
$7.20 a minute, what a pretty penny
Why has no one made a bb accelerator? bb's are cheap.
I Started one a few years ago but unfortunately I've had no time to work on it. The projectile geometry seemed to make it quite inefficient in my initial testing but coil guns aren't that efficient anyway. might get it finished one day!
If you could rotate the pennies during propulsion the sintrifical force would stabilize them similar to a frisbe
Finally found a use for those penny rolls eh?
that's sic bro ...I wonder if spinning 2ps wud add speed lol
dave Yates Cheers. It should increase stability and reduce dragg a bit maybe making the projectile go further
Rogue-Electron - next try rail gun with spinning 2ps lol keep the vids coming bro I love this shit lol
Another way to throw money
You could equip sharp disks instead of coins to double its effectiveness. Just saying.
Is it possible one day we will have coil guns that can shoot projectiles faster then a bullet? Our these really guns of the future like in sci-fi games / movies?
Now feed it with some supercaps at 200 Volts :D
If Only I Could!!! :-)
Yes very nice but nothing compaired to the awesome power of the Gauss Gun
By AVA Magnetic Levitation its new tech using diamagnetics and now power.
Vid out now ( Gauss Gun )
PS I like your work
AVAMagneticlev Just watched it. Not bad ;-). I lost all my graphite when i moved and all my Magnets made love with eachother and left nothing but Magnet Dust in the boxes.how much would it cost to build a complete track, like a simple oval or something?Thanks
A few $100 bucks depending size and scale you choose
A great idea for ammunition! Straigth forward shooting of money, how convenient.
pRopaaNS It's everywhere and it's cheap :-D. The Mk4 Coil Gun will also be using money for projectiles... When it's eventually finished
Thanks to HVDischarge for sharing this, and information on how he built it. It really helped us understand and improve on his design. We are currently creating a new modern automatic coilgun like this one, but with an easy to follow guide to go along with it that you can follow and make a similar one yourself from scratch! We just need some help first. For more info please check out our kickstarter page here: kck.st/1iwmgqD
So that's how you use your money!
+Mukesh Kumar "The fun way to pay"
Rogue-Electron Yeah!
+Mukesh Kumar IS you could build me one that shoots fivers I would never pay for anything with my bare hands again.
It's more like a coin gun :D
cheap ammo :)
Also keep in mind this is cheaper than most firearms to shoot. :P
Lol. I guess it all comes down to production costs and durability. I'm not complaining though as my gun wouldn't work with the metals most coins are made of.
sharper projectiles, belt-fed mechanism, higher voltage, more stages and it will be perfect
That's a money shot!
This would be great for a game of bloody knuckles.
Optically triggered. Have to remember that the next time someone blows up on me :)
Great video man.. I was wondering how you sequenced the coils. Saw the MOSFETS inline down the side. Nice build, would love to see it scaled up both in size and joules... May be on to something.
fla playa haha. Thanks :-). once i've moved house and got the 1.6Mw cap bank operational i will be going for more power!
1.6 MW cap bank? How do you determine wattage from voltage and farads? Nice again tho.
fla playa By taking the maximum voltage of the caps and the max current discharge rating and multiplying them. 1.6Mw is conservative as i think the actual figure is around 2Mw :-D (peak).
