Just found your channel today and I love what I've seen so far. I have to say much to my delight you remind me of a certain Canadian Uncle of ours. Thank you for brightening up my day.
Just this afternoon I discharged two 400V caps from a power supply with a screwdriver. Not the best I know but it was a good reminder of the power that can be stored. Your discharge reminded me of that.
@@ElementalMaker Hey man ive been trying to become a patron and everytime i try it tells me there some unrecoverable server error... heard anything about it?
@@ElementalMaker What if a nuclear powered vehicle were able to send impulses of electricity in front of it powering each coil in a tube right before it got to them? I Guess it might be more efficient to just propel it by conventional means, but this would be a really cool way of transporting things with a self powered/contained power "projectile" with the coils acting as rails of a train. I guess that's what a maglev is. Hmm.

If you have anywhere around you that still processes disposable cameras you can usually just go in and ask for a few of the empty shells. Any one with an actual discharge lamp for the flash has a low wattage ~300V power supply in it. A whole mini coil gun could probably fit in the camera shell.
I made many coilguns back when I was a kid with those. They are quite fun, but once you start adding capacitors in parallel, it takes ages to charge. This boost converter puts out a ton more current than those little camera flash boards.
Yes, I was thinking along similar lines. I'm pretty sure the cap in this video is just massive overkill and that a 50uF 300v cap should probably work as well. After all, it really doesn't take much energy to shoot such a tiny projectile at such relatively low speeds.
@@tarstarkusz you are correct a big capacitor like shown would have a lot inductance and extend the discharge and may start slowing the projectile if current is still flowing after the projectile passes halfway inside of the coil. You want extremely fast rise times and a quick pulse.
Oh sure. See also: Portable Super Coilgun: th-cam.com/video/rclLsQ9nyeg/w-d-xo.html&feature=youtu.be th-cam.com/video/-mjDqp_oWZk/w-d-xo.html th-cam.com/video/YLOYxsqvjw0/w-d-xo.html
Gotta love any video that throws a hidden south park reference in. Now here is a thought for a possible future project. I'm sure you have seen the experiments using a vacuum with a burst disk to propel projectiles. NightHawkinLight did a good one. And Mythbusters did one where they shot a ping pong ball at over mach 1. Now it would be great to see that technology mixed with coil gun tech to get a projectile going even faster. This internet fad is great seeing as how it allows people to connect with like minded individuals. I just wish we lived closer so I could help you out with stuff. Oh and how dare you ever use the term scale down. Bad ElementalMaker. Anyhow keep up the good work.
Haha glad you caught the reference! Your the first comment to mention it 👍. That is a very cool idea, I've wanted to try the vacuum cannon since seeing nighthawkinlights original video on it years ago. Sounds like an awesome match
Oh yes. Hi! How are you? See also New Portable Super Coilgun: th-cam.com/video/rclLsQ9nyeg/w-d-xo.html&feature=youtu.be th-cam.com/video/-mjDqp_oWZk/w-d-xo.html
That looks like one of those 0.1F capacitors... My dad used to have like 50 of them. Then my mom got tired of his vintage electro collection, so he had to scrap them. They were brand new, scrapped by Siemens (where he worked) when they abandoned the multi-rack mainframe design somewhere in the 80s (one of the racks was a power stabilizing battery of some 120 of those badboys. Computers ran 30A currents back then. Hot business, quite literally). Anyway, I managed to keep 3 out of my mom's sight. We destroyed one using it to explode smaller capacitors (fully charging the big one, then inverted connecting a smaller one. The big one would load 100x the max charge of the smaller one into it and boooooom. But the big electrolyte capacitors are not made for load dumps. So after a few times, it started leaking. We also were able to charge it less the last 2 times (probably shorted out some of the surface inside). Made for an interesting disection afterwards... Now I wish I still had them, I could make a 50 stage coil mass-accelerator... (nice euphemism, btw) Or perhaps run a small backyard roller coaster off of them... (at least for a couple of runs)
Xeon strobe lamps make a great trigger as well, some of the power is wasted in the light and heat of course, but in the bigger coil guns ive seen people make, the SCRs required are very expensive, so strobe lamps make a good balance between price and efficiency.
Flash lamps also have extremely fast rise times compared to any semiconductor. For a coilgun you want all current to end by the time the projectile is passing the halfway point inside of the coil. Otherwise if current is still flowing the projectile will be slowed. You can play with the timing by the inductance of the coil. Another benefit of flashlamps is their awesome ability to explode louder than a gunshot and throw quartz glass everywhere. I once dumped 20 disposable camera caps through a camera flashlamp. My ears were ringing for a couple hours.
i've heard people use light barriers to rectify the problem, but to do it correctly you'd need to space the coils more or use a shorter round, basically so the projectile stops obstructing the light barrier before it reaches equilibrium in the coil.
he jumped up and came to me, looking confused, when you switched it on. i was working with him with a dog whistle some years ago, it could sound similar
what if you used coils wound in different ways? or if you put a larger coil around that coil? can resonance generate a magnetic field in the smaller coil, and would that make it stronger or weaker if it can? can that feedback you mentioned from the collapsing field be directed into another coil?
If you add an IR interuptor to detect when the projectile exits the coil, then turns off current to the coil, the velocity of the pronectile will not be decreeased as it exits the coil by the residual magnetic field
@@ElementalMaker Nope, Just add one detector before the entrance and one where the projectile starts. Have current dump into the coil when the object triggers the first detector, at the start, and stop current flow when it enters to the coil. You could even work out a way to observe the velocity of the object and calculate how long the coil needs to stay on before the the object passes through the center. There is potential here for a very interesting project. I would also recommend you look into rodin coils.
@@ElementalMaker you should also consider using a laser range finder pointing down the barrel of the coil gun to do this very same thing. Of course, you would need a microcontroller to handle everything. Using an arduino/laser range finder has the added benefit that stacking coils would be very simple. You could have lots of very small pancake coils. Also you should think about using a teflon or glass tube for minimum friction
200V is actually a quarter of the power, as the potential energy climbs quadratically with the voltage. U = 0.5 * C * V². where U is the energy, C the capacity, and V the voltage.
if you were to fix the accelerator mechanism itself would you get better puncture results at lower voltages since i would think you are losing some velocity when the magnetism of the coil actually grab and flings the projectile? I guess the comparison would be trying to apply force to a movable object while you are in water, the object will indeed move forward but you yourself will also be moved backwards at the same time.
When i was a 6 i pounded a few nails into a board then wrapped wire around the nailheads. My parents never jumped and screamed lounder than when i grabbed the bare ends and started to stick them into the wall socket. Because they yelled so much i wanted to know why so later i grabed the vacuum plug and plugged it in while holding the blades. And i never did that again.
That's a right of passage for curious kids! 😂 I remember doing similar around that same age, but it involved my tongue. With a wall wart in between though luckily.
Mine was my mom's Bobby pins . I did it repeatedly, not just a few times either. That was the beginning of life and poor thinking leading me to be a plumber and not an elechicken.
Bloody brilliant video! You have a really good way of teaching ( I normally have the attention span of a goldfish ) But your way of explaining things just keeps me interested. I don’t have very much as a single parent with two daughters but I will become a patreon to your channel because you actually do things that you are passionate about and don’t play to the TH-cam corporate bullshit fiddle.
I have been trying to figure out a way of making a electric gun for my toy metal army tank.I wonder if i could apply this theory somehow.Thanks man.Great videos.
Must be snowed in. E= 1/2 (C)(V)(V). Try mono-stable CMOS pulse generator to fire gate for repeatable width pulses. MOSFETs are cheap. More turns on coil. Thanks Mr. Wizard. Extra for experts, fire straight up, measure height, and time of flight, then you can work out the velocity, and acceleration and energy of projectile. Good for explaining integral calculus. integral of A = V, integral of V=S.
If you don't want to pop a bunch of SCRs / Thyristors, just get some Semikron Thyristor "block" (used) from ebay. You get two SCRs in series in one block, so if you pop one, you still have another. I got 3 smaller blocks with 2kA peak in parallel with a bus bar. To fire those, I use a 1mF cap and a relay :)
Have you tried any sort of cooling technique? Maybe if you cooled the coil and projectile with liquid nitrogen you'd increase the magnetic flux density I think? Wonder if that would have any noticeable effect.
Man, scale that into a higher voltage capacitor(there are some small 400vlt ones, 2 of them would weigh about a pound and a half. Thinking of how to get this done in a backpack form, could carry a couple capacitors for multiple shots, and make a rifle that uses this concept, it would be crazy dangerous to those who don't understand what they are doing, but it would be pretty cool, doable and at least as useful as a PCP 50cal air rifle. And less expensive, could probably encased the whole thing into epoxy(?), I don't know, but I think it would be a great thing to have, to show off to your friends when plinking cans in the back yard, to getting the children very interested in how electric/magnetism works. Lol Great video, thanks for it, take care, God bless.

Half the energy of that coil gun went into propelling the nail, and the other half went into the gun recoiling backwards. Mount the gun, tape it down or whatever, so it doesn't recoil and you'll double the energy that goes into propelling the nail.
ElementalMaker true. it’s worth it for science. Unfortunate but still worth it. Just don’t bust out your window with it 🤣 I don’t know if that’s worth it

Wow I had never even heard of such a device, but I have seen others using Xenon flash tubes as triggers so it appears arbitrarily similar in function. Very cool! I need to read up on these!
It's a triggered spark gap initiated with a high voltage spark. The high voltage ionizes the air around the spark gap therefore lowering the resistance causing the capacitor to discharge at a lot higher amperage than 1400A. Same concept as a flashtube but without the tube. Hope it helps.
I found it on FB marketplace for $25! The guy had two of them for $50. Truly an amazing find! I did a video showing them here th-cam.com/video/_dN_YMLrkZw/w-d-xo.html

Great video! Based on the damage to the can I would guess you got the steel rod accelerated up to at least 300 feet per second. What are the main differences between this and a railgun? I think on a railgun the projectile itself completes the circuits, but I could be mistaken
@@ElementalMaker Thanks! Yes you were pumping a boat load of energy into that setup. Luckygen1001 has a video showing an 80 yo Tungar battery charger with a gas diode that was cool. I only know enough about electronics to make smoke. Lol
If you don't want to use a huge cap like here, stealing the caps out of disposable camera's, as they also come with a charging circuit, is a great way to build these.
I used those smaller ones from disposable cameras back when I was a kid, but this one has the capacity of around 100 of those, and is a much easier form factor to work with.
The Shaft has entered the Cavern! side note, if you have an ad in the video ill "watch" it.

@@ElementalMaker I'd say so yeah, haha, maybe it's because i have a 4K monitor. I'll consider giving on Patreon if it can make you improve your videos even more. :)
I wanna know whats the schematic digram of your firing mechanism cause i can see that you didnt use any sensor unlike most people will use. Thx in advance man
@@ElementalMaker Ive found your video about the trigger circuit but the 2nd video where you demonstrated with the coil the schematic looks kinda odd, the scr looks gonna explode when voltage goes to the 9v battery then to the gate of the SCR where it's threshold is under 6v and I can see there's no switches apparently?
I've done every step, every component is the same also the circuit you shared from the description yet it failed, thus both my scr are damaged now, any idea of why it failed?@@ElementalMaker
I want to use 3 sets of 7 stage 6inch wide 8inch long coil rail 1st stage 2"L stage 2-7 1"L for a ion accelerator to increase thrust on a ion drive. Increase the speed of the ion and increase the thrust. Do so fast enough and you can get proper acceleration and maneuverability in space. And possibly if using a ion drive and a multi stage accelerator to accelerate the ions to near light-speed out the back of the craft you could get very good acceleration/ deceleration of the craft and Achieve near light speeds. We all know NASA and there mk3 which was a big waste of time and money because by the p/w ratio it's 500lbs has a thrust of 278 millinewtons and the original ion drive they made was around 10lbs with a thrust of 92millinewtons so the mk3 has 3x more thrust because they made it have 3ion rings cuz it looks cool but they didn't focus on ion speed improvement no they made it 17x less efficient 3x more thrust and 50x heavier ,spent probably millions and years making it when they could've just used 3 mk1's to get the same thrust.a and used that money and time to improve the mk1 with a ion coil rail drive. God damn it some give me a job! Any tips on what power requirements an switch for my scale would be great rant over.
Couldn't you use a electric solonoid for like a hydraulic system to do this? I play with solonoids all day at work on heavy equipment. Just throw more voltage at it??
For switching? That's essentially what a relay is. Eventually any physical contact will deteriorate. Solid state is the only long term solution here that I can see working.
So, the next logical step is a multi-stage coilgun... FOR SCIENCE!!!
It might need a FULL BRIDGE RECTIFIER!
Do it
I think your absolutely correct! That has to be the next step 👍

magnetic coils in series triggered in series can give a massive boost in velocity, timing on triggering them at correct speed is the problem
i've heard people use light barriers to rectify the problem, but to do it correctly you'd need to space the coils more or use a shorter round, basically so the projectile stops obstructing the light barrier before it reaches equilibrium in the coil.
depending on the spacing of the coils you could probably use a reed switch at the end of one coil to fire the scr for the next coil

Sweet Coil gun cool vid.
If you don't want to pop a bunch of SCRs / Thyristors, just get some Semikron Thyristor "block" (used) from ebay.
You get two SCRs in series in one block, so if you pop one, you still have another.
I got 3 smaller blocks with 2kA peak in parallel with a bus bar. To fire those, I use a 1mF cap and a relay :)
Yep I've been keeping an eye out for those monster SCR's!
Man thank you for another quality video. Has anyone said you sound just like Negan from The Walking Dead?
Glad you enjoyed! I hear neegan and kronk quite often 👍
Won't be long be before Patreon doesn't like you either.
Yeah it's looking that way isn't it? Crazy world we live in.
@@ElementalMaker
We are living in Orwell's worst nightmare.
At least I know how to fire a nail through a can now!
Have you tried any sort of cooling technique? Maybe if you cooled the coil and projectile with liquid nitrogen you'd increase the magnetic flux density I think? Wonder if that would have any noticeable effect.
Haven't tried anything like that yet, but that would be awesome to see the difference in a super-cooled coil vs room temp! Very cool idea!
Man, scale that into a higher voltage capacitor(there are some small 400vlt ones, 2 of them would weigh about a pound and a half. Thinking of how to get this done in a backpack form, could carry a couple capacitors for multiple shots, and make a rifle that uses this concept, it would be crazy dangerous to those who don't understand what they are doing, but it would be pretty cool, doable and at least as useful as a PCP 50cal air rifle. And less expensive, could probably encased the whole thing into epoxy(?), I don't know, but I think it would be a great thing to have, to show off to your friends when plinking cans in the back yard, to getting the children very interested in how electric/magnetism works. Lol
Great video, thanks for it, take care, God bless.

You might be able to use a simple mercury tilt switch to handle that current. Might catastrophically explode though... CODYDON!!!
Mercury to handle high voltage/current.... don't do it.
add timed compressed air, could increase velocity.
Oh sure.

Just the tip. And just for a second. Ive said that many times. How about a wiring diagram for the charge and trigger circuits. ??
Great video!
very nice
Should try a professional strobe power pack. I know the voltage is high, they're basically just boxes filled with huge capacitors.
SouthPark Brilliant Love it
Scale it Down? Methinks Thinks NOT :) Now, Whose house did I see those 1000V capacitors at....
You better go find those caps before I do! LOL
Half the energy of that coil gun went into propelling the nail, and the other half went into the gun recoiling backwards. Mount the gun, tape it down or whatever, so it doesn't recoil and you'll double the energy that goes into propelling the nail.
NOOO!!! Not the Corvette :( and good shit. I’ve got an old cap from an a/c unit, I think I may try this out at home sometime
Yep she took a little ding in the name of science 👍
ElementalMaker true. it’s worth it for science. Unfortunate but still worth it. Just don’t bust out your window with it 🤣 I don’t know if that’s worth it

Do you really need a lot of current for this? I would think this would work fine using a much, much smaller cap, but with the same high voltage.
I've used smaller caps of the same voltage but they do not generate very high velocities.
i think because the smaller caps dont generate the same high current, unless you use supercaps i think, unless they are also amp challenged.
I think it's the inefficiency of the coil. A nail which weighs a couple of grams moving at a couple feet per second does not need that much energy.
You can use a trigatron as a really fast no contact trigger
Wow I had never even heard of such a device, but I have seen others using Xenon flash tubes as triggers so it appears arbitrarily similar in function. Very cool! I need to read up on these!
It's a triggered spark gap initiated with a high voltage spark. The high voltage ionizes the air around the spark gap therefore lowering the resistance causing the capacitor to discharge at a lot higher amperage than 1400A. Same concept as a flashtube but without the tube. Hope it helps.
i want to see your take on a functional multistage coilgun, one that operates and handles like a firearm, i bet it'd be sick.
You are very clumsy on your workbench but I love it!
Also, where did you get the power supply? I really like it.
I found it on FB marketplace for $25! The guy had two of them for $50. Truly an amazing find! I did a video showing them here th-cam.com/video/_dN_YMLrkZw/w-d-xo.html

Ah, summer camp.
Can you find a way to efficiently speed up electrolysis to liberate hydrogen more quickly like Stan Meyer claimed....?
whats the diameter of your copper coil?

Great video! Based on the damage to the can I would guess you got the steel rod accelerated up to at least 300 feet per second. What are the main differences between this and a railgun? I think on a railgun the projectile itself completes the circuits, but I could be mistaken
You are correct 👍 glad you enjoyed!
What if you used graphite rods from a carbon-zinc battery as your contacts? I don't think those will weld.
That would probably work for a bit, but even those would eventually just vaporize away as CO2. Solid state is the way to go.
@elementalmaker, sweet power supply. What brand/model?
Could you get away with some solid state relays? Response/activation time would be a concern.
That's a Sorensen 15-20 Power supply. Truly a great unit. I don't think ssr's capable of this switching current are available /affordable
@@ElementalMaker Thanks! Yes you were pumping a boat load of energy into that setup.
Luckygen1001 has a video showing an 80 yo Tungar battery charger with a gas diode that was cool. I only know enough about electronics to make smoke. Lol
th-cam.com/video/JV9Zj8agZXE/w-d-xo.html
i dont know much about electronics and such, but if you add more coils, could you have more
power, or is it the batteries holding the volts?
If you don't want to use a huge cap like here, stealing the caps out of disposable camera's, as they also come with a charging circuit, is a great way to build these.
I used those smaller ones from disposable cameras back when I was a kid, but this one has the capacity of around 100 of those, and is a much easier form factor to work with.
love the vids
The Shaft has entered the Cavern!
side note, if you have an ad in the video ill "watch" it.
Very sad the camera have such a craptacular quality. Everything is nice, experiment is entertaining, commentary is good and funny, it's also educative. Continue your good work.
Is it that bad? I know its a older camera, but its still full 1080 HD video. Thanks for your kind words, I'm glad you enjoyed.
@@ElementalMaker I'd say so yeah, haha, maybe it's because i have a 4K monitor. I'll consider giving on Patreon if it can make you improve your videos even more. :)
Take a shot every time he says "a brief instinct"
Zero shots due to your misspelling. Otherwise deadly and I don't recommend.
DAMN LOCK NESS MONSTER :) TREEEE FIDDY
A best result would be achieved if you hold the canon tightly as part of the kinetic energy is gone moving the canon backwards.
I wanna know whats the schematic digram of your firing mechanism cause i can see that you didnt use any sensor unlike most people will use. Thx in advance man
@@robertabihay4196 I have some other videos on the trigger circuit
@@ElementalMaker Ive found your video about the trigger circuit but the 2nd video where you demonstrated with the coil the schematic looks kinda odd, the scr looks gonna explode when voltage goes to the 9v battery then to the gate of the SCR where it's threshold is under 6v and I can see there's no switches apparently?
I've done every step, every component is the same also the circuit you shared from the description yet it failed, thus both my scr are damaged now, any idea of why it failed?@@ElementalMaker
What are the specs on the clamp diode?
Up next on Rulof Maker: Making a Coil Gun
Hahaha I bet your right
You gotta make a multistage coilgun yourself and make it better than the others! Would be exciting to see
Thank you everyone for paying your health insurance premiums so I can get paid to watch this at work at your health insurance provider. 👍👍
Whatever we can do to keep you happy Jeff! 🤣
It should be possible to calculate when to fire the next coil and have them stacked right next to each other.
Just the tip. Well that never is enough!
Thumbs up simply for the lock ness monster reference and the video wasn't bad either. Lol
I want to use 3 sets of 7 stage 6inch wide 8inch long coil rail 1st stage 2"L stage 2-7 1"L for a ion accelerator to increase thrust on a ion drive. Increase the speed of the ion and increase the thrust. Do so fast enough and you can get proper acceleration and maneuverability in space. And possibly if using a ion drive and a multi stage accelerator to accelerate the ions to near light-speed out the back of the craft you could get very good acceleration/ deceleration of the craft and Achieve near light speeds. We all know NASA and there mk3 which was a big waste of time and money because by the p/w ratio it's 500lbs has a thrust of 278 millinewtons and the original ion drive they made was around 10lbs with a thrust of 92millinewtons so the mk3 has 3x more thrust because they made it have 3ion rings cuz it looks cool but they didn't focus on ion speed improvement no they made it 17x less efficient 3x more thrust and 50x heavier ,spent probably millions and years making it when they could've just used 3 mk1's to get the same thrust.a and used that money and time to improve the mk1 with a ion coil rail drive. God damn it some give me a job! Any tips on what power requirements an switch for my scale would be great rant over.
Couldn't you use a electric solonoid for like a hydraulic system to do this? I play with solonoids all day at work on heavy equipment. Just throw more voltage at it??
For switching? That's essentially what a relay is. Eventually any physical contact will deteriorate. Solid state is the only long term solution here that I can see working.
Do you know the Benefit of a thicker copper coil or is there a ratio of amps to coil ?
Another youtuber made a video abiut a different coil design which is more efficient at accelerating the projectile can you test that?

Great video do you have a schematic for the boost converter
In the description is the link to the site I found it at. They have the full schematic and a trace picture so you can make your own pcb.
Thanks I have recently obtained a lot of those big capacitors and I have been having difficulty charging them
Hey crunk. Could you pull the high voltage lever
