Hi Guys, Thanks for your views and support. I'd like to clarify a few common questions / comments about this device: -I think the maximum speed I saw was around 400 RPM. -Yes, this is effectively just a coilgun bent into a closed loop. -Yes, this the principles are very similar to a particle accelerator. However, in most particle accelerator configurations, an *electric* field is used to generate most of the forward acceleration, whereas magnetic fields are used for confinement (or focusing, in the case of an electron beam). Creating useable forces from electric fields requires tremendous voltages, and special electrical insulators to prevent arcing. -Yes, the track could probably be balanced by the use of another ball 180 degrees out of phase, but it would increase the complexity of the coil control considerably to ensure the balls remain approximately 180 degrees apart. Left to their own devices, I've found that the phases between multiple balls will drift at random. -Yes, a similar device could be created using an electrical current through liquid mercury. This is known as magnetohydrodynamics. Mercury is very expensive and difficult to acquire in the United States because of the health hazards. -It's *not* a perpetual motion machine (implying 100% efficiency). In fact, I believe it's less that 5% efficient. 95% of the energy going into this from the battery is just heating up the coils. -It's *not* capable of flying like a "UFO". I think this idea comes from the notion of "inertial propulsion" where some people have mistakenly confused the torque generated by a high speed gyroscope with translational force required for flight. A gyroscope on a shaft can appear to lift itself against gravity, but the lifting is generated by torque, so it depends on having one end of the shaft firmly forced against the ground. -It's *not* going to be able to recover power from the moving ball with a "generator" coil. This is because the ball is not magnetized. This would be possible with a permanent magnet ball, but the efficiency of the recovery would probably be extremely poor.

I would love to see a project like this escalated to an absolute maximum. Like starting from this what is the next step to increase speed? More coils? More Power? Decrease friction, perfect timing? Vacuum? better materials? Cooling? synchronize 2 balls for better stability? Would love to see this getting perfected to the absolute extreme near the breaking point of every component. I love projects like these. please continue!

Ah yes, the Drywall Hole Puncher 400

Wow. The new and improved version looks like it might year a hole in spacetime. Good job!

In the 80’s I created one using old-school techniques. The track was much larger, on the order of a couple of meters around. The track was three rails, with the outer rails conductive neutral and the middle rail non-conductive, but with a hot conductive surface right before each coil. The metal ball would make contact between the hot and one or the other neutrals, and the ball itself completed a circuit that energized the next coils (or several coils). The middle rail wasn’t actually conductive like the outer rails. Rather, it had a conductive surface only where it needed it to allow the ball itself to make or break the circuit. No microcontroller. No PCB boards. Just wires (lots and lots of wire), heavy duty foil, solder, the rails, bracing, and a safety shield. And sparks, but those were fun! And it was fast AF. Only friction, air resistance, and probably residual impedance to limit the speed.

You made my dream machine and called it an accelerator...it's crazy how more that one person think up the same things. You're awesome though. Kudos.

Try adjusting the distance between the coils and the sensors, and add delays that decrease as the speed increases, so that as the ball goes faster the coils can "adjust" their activation times to get more speed out of it. You could make a clock like system using the four sensors to gage the speed changes too.

Nice idea, I'd suggest adding a little more signal processing and timing systems to the control circuitry, working out the velocity of the accelerated mass and adjusting the magnetic pulse to account for the speed. As the ball gets faster you seem to be hitting the limits of your timing control system as there does appear to be a maximum speed (based on the audio). You could move the light gate sensors a little further from the coils and add a small delay or compensator to the trigger pulse that can be adaptively changed based on the calculated velocity to maximise the achievable top speed.

This is a fantastic project. You should submit it to somewhere like hackaday so more people can see this. Really great work, thanks for sharing it!

Great project. Lack of rigidity induces oscillations that seem to slow or accelerate the ball, depending on their phase relative to the ball position.

Soon I might be seeing home-made particle accelerators. Keep up the good work.

As an internet expert on ring accelerator videos, I feel compelled to let you know exactly how to do this right instead of building one myself. Just kidding sir! You keep doing this and I will sit at my desk and enjoy it. New (and possibly annoying) subscriber!

I would recommend a micro controller to do the triggering of the coils. This will help you control the ontime of the coils depending on the balls velocity. And you can also monitor the balls speed in real time. Nice project

This is amazing and absolutely hilarious to watch it rev up and fling the balls off! My tip for the next version is to make it a tube rather than a "tray" or "track". Which a secure trap door to place the ballbearing in as well as nice and long holes for seeing the ballbearings spin visually.

I thought I was short on tech. I loved science projects in grade school. For those who aren't literate that is a basic mock up of electro propulsion. You know the big guns on naval ships. This video gave the understanding of how those work. No need for gun powder or fuel to propel an object at great speed.

I"m impressed you did that all with out using some sort of micro controller for the timing and ball location. Awesome project, I'm going to make a version of that for sure!

absolutely fantastic accelerator

This is genuinely one of the coolest things I've ever seen

I'm very much intrigued with your work and I'm very grateful to see this today.

This is amazing work. I love how you designed the coil igniters. I had a similar idea instead of a steel ball in a half pipe it was ferro fluid in a torus gyroscope . My hypothesis was that it would levitate .

Excellent project, exactly this idea someone have used to create a rotative engine, using impulses, just studying how to approach to the perpetual engine or to minimise the consuption. Impulses, frequency, resonance, are minimising the permanent power consuption. Thank you for your amazing video!

Imagine having this type of thing on your Hot Wheels track set as kid, it would be a dream come true.

If we're not careful with our youtube views, this dude is gonna make a magnetically accelerated weapon

Get 4 going, in synchrony, so that the inertia is balanced, and you don't have to hold on place. Then you can ramp it up to even more dangerous levels. Nice work on this. Pretty cool.

It looks like to me you made a sensor brushless motor. really quite impressive good job.

Reduce your friction, use metal rounded guide rails for the ball to travel along, and you should also bolt it down because I'm sure each time the ball passes at high rpm it can warp the plastic causing friction banding effects.

Kind of looks like how UFO's light up when hovering. Excellent work

I noticed a defect in the design of your track. When making your track, you neglected to subtract the length of the track, that is occupied by each of the coil modules. This additional, strait, segment of added track, warped the perfect circle, produced by your printer. Of course it still works. But, I would like to see how stable it would operate with the correction.

This is such a weird, pointless little thing, yet something about its design and how the video was made completely captivated me, I've never paid this much attention to something in my life.

cat is going to have a hell of a great time trying to get that ball.

so incredibly interesting how much speed the ball lost once the track wasn't held in place, physics is so neat (btw get the engine mounts on your car checked/tightened every once in a while, same concept)

Just keep doubling the number of electromagnet coils. After that you just need some sort of firing mechanism. ;)

I'd love to see a fully contained version of this sold as a decoration piece, and sign me up as the first buyer 😊

Dude this is amazing! Small improvements might be to test the friction of the 3d print material and see if you can replace or cover it with something with less friction allowing less energy loss and higher speed, then maybe even doubling the electro magnets you use to improve output, but I think at very high speeds and a high latency detection system causes a max speed, so if you could possibly try and reduce latency or go around this problem, one trick is to have a speed sensor on the track and keep track of the balls speed, with this info calculate with a separate pc board the time it takes that it would travel to the magnet and then activate it with this method, also having the current infa-red sensors to improve the calculations? secondly I like the open design but the balls might hit into the walls of the magnets or even as seen fling off, so to prevent this make a better curve at the top wall not allowing it to fling off and making it perfectly line up with the magnet walls, since even a 1mm difference gap could cause energy loss and stagger the performance. I am highly invested in this since I find this extremely interesting and I would love to see how these ideas might improve your current design!!

Thank you for sharing this kind of content to the world... You've done a great job youtube needs more people like you ✌️

When the ball flew off the track I instantly thought of unstable isotopes and electron loss. Uncanny resemblance.

Great project. For version 3 you should consider adding a straight turnout section in the loop. You can cover this turnout with a gate shaped like the curved sections. Once the gate opens the balls will exit the loop. This way the accelerator can be used as a launchpad. Somewhat like the slingshot rocketlancher made by SpinLaunch.

my youtube recommended is going to a different level.

In a year or two this man may be in the news for building a accelerator the size of a dumptruck in his backyard

Far the best Prototype i did see. Great job mate! Let’s find out how we can improve this together…

Advice for version 3; place 4 more sensors halfway between the the axis of the magnets. The formula to calculate the velocity of the projectile and trigger the magnet can be greatly improved per quarter cycle and totally frequency. This way, your triggers will be more accurate as the system spins up to maximum set velocity. I love this project and look forward to your continued work

Little did he know he just invented the basis for a supremely powerful orbital rail gun.... Legit

Your work is impressive, and your narration is effective to draw and keep attention of audience (viewers).

Nice concept, but it can be simplified. For example by removing IR sensors and use coil itself (pass a small current thru coil and monitor it's change when ball approaches)

5:14 If you put 2 or 3 balls stationary next to each other, then accelerate another into them, will it act like a Newton's Cradle, with only 1 ball going around at a time, sending the next in line around when it hits the back of the line?

my goodness someone could create a very powerful weapon with a simple setup the possibilities are endless.. many different types of things can be created or repurposed with such simple technology. love this experiment. reminds me of things i use to randomly make as a child. fun stuff

This man will soon discover the Ball Boson!

The balls ran slower after you added the wall to keep them from flying out. I'm sure you know this already but as a sphere rolls the surface near the axis of rotation has a lower surface feet per minute than the equator of the sphere. Is it possible the arc of the track is near that of the steel ball? If you make the track noticeably larger in it's cross section diameter only the equator of the steel ball will be in contact regardless of where it is on the track. In example, 25mm ball make the track 40mm or more if you like. On a completely different note, hope it's OK to live a little vicariously through you, if you were to move the sensors away from the coils and use something like an arduino to trigger the mosfet and programmatically change the timing off the coils so the ball can be hit harder and longer for the higher speeds. You can measure the time between two sensors as a tachometer for ball speed. Just a thought.

Really awesome project, I wonder if you could use this design with those new rail guns to increase the firing power i guess would depend on how quick you can switch the coils on and off. people are awesome

I gave you a like and I subscribed, I always enjoy a good sense of humour and if you accidently impart something useful then I promise you that I really will laugh out loud! Best wishes from Ireland mo chara, keep up the work.

Увидел несколько недоработок и хочу поделиться. 1. Твоя площадка стала овалом из-за магнитных вставок. 2. Когда шарик разгоняется, то его поднимает. Соответственно он уже не попадает в центр магнита. Из-за этого слышно удары. 3. Это мысль. Что, если вместо шарика взять ось, и сделать что-то наподобии мельницы. Тогда у тебя получится подобие двигателя.

Let's see it run with 4 . Fantastic job keep it up 👍

Hey man, I love what you are doing! Great job on the video and fantastic idea!

The cats are slowly becoming more advanced

5 year ago when I was in 8th class my teacher teaches me EMF for exam syllabus so i feel intresting then I developed a looping system and micro rocket but i created only for my enjoyment but now day's i have seen 1% of my invention on KZfaq videos 🤣😂🤣

What if you make the track pieces as close to a perfect circle? I believe this would give you a consistent centrifugal force, making the acceleration more consistent and ultimately the speed increase and better resonance. You would need to design for the coils ID to have a very slight radius to accommodate for a true circular path. Awesome project man. Keep it up!!

Man imagine this with 8 coils. That would be insane.

Oh! I see you built a wobble drive. As the ball is pulled through, and accelerates the mass is increased. For a brief second. If you could have it always trigger in the direction of movement, you'd have a good space propulsion system that doesn't require the expulsion of mass.

I have been addicted to many things alcohol majuana... and others but it was not Intel i got addicted to struggle that i started to feel better. Spirit science thank u for saving my life and my family's i love you man. For all who chose to love themselves and choose to strive for internal and external acceptence i love except u for all your perfect imperfections.❤

Wow! That's fantastic. I've been dreaming of making something like this for years now, so wonderful to see it done. I will definitely have to give it a go. Could you go a step further and add 8 secondary coils, 2 in-between each to create a return charge to battery when running the magnetic bearing? Very inspiring.

I'd like to see a Mobius strip figure 8 track or adjacent loops that sway or gyrate as a whole unit. This is very inspirational.

Dying to see one of these set up in the style of the LHC. Like a small loop with gates to consecutive larger loops.

You're gonna mess around and end up making a flying saucer you genius you

Nice project. Comment from an EE - I think your speed is being limited by the slow decay of the coil currents, due to your back-emf quenching diodes. The voltage available to reduce the current will be only around 0.8V during turn-off which will give a long tail to the current waveform, holding the ball inside the coil for a while. You could try a few diodes in series or even back-to-back zeners for coil quenching to increase the current decay speed and I bet that will speed up your accelerator. Best of luck, a year too late!

Would be interesting to see if it could be made to use two balls to balance its self

Making this work with a replacable power cell, and an exit tube/rail, would be fascinating to see. Especially in competition with a Slingshot.

bro is cooking smt , he bouta be the IRL TONY STARK

Will there be a third part to this series? i would love to see a controlled release mechanism for…science…

Seria possível criar um projeto desses em escala maior??? Parabéns pelo projeto.

It's like a partical collider but slow. I dig it.

This principle is relevant for the future of flying.

Careful brother, this technology is rail gun technology 😉 There's something very satisfying about this thing to watch.. What if all 4 coils was constantly on? Or if your sensors were a little further away from the coils? More propulsion at higher speeds maybe 🤔 If your run was straight and you had 6 to 8 coils, put doubt or triple the voltage you would have a very powerful projectile launcher/shooter 👍🏼✌

Hey man. That's cool. I didn't watch the whole video though, so may have missed something. Just a suggestion, can you program it to keep the balls π out of phase so they are always counter balancing? Would increase efficiency greatly!

Concept:Those ring like things are called solenoid Solenoid: Wire wounded around a ring like particle When current is passed through the wire Magnetic field is generated perpendicular to the direction of flow of current That magnetic field accelerates a magnetic Particle direction is perpendicular when particle is traveling perpendicular to Magnetic field Particle direction is Hexial when particle is traveling at an angle to Magnetic field Particle direction doesn't change If it is Parallel to Magnetic field

My cat would love this toy

Very interesting, I can see a way you could turn that into a generator.

Cool, now we all want you to build the giant Time Machine from the film Contact. :)

what software is that you are using to show the design? Is it Inventor by autodesk?

you're doing awesome stuff bud. Love the background music!!

The new generation of coilgun

Your bills are very nice. I remember the first one that you built and then I seen this one at its modifications very nice.

Aliens have already mastered this, they created the flying saucers which can fly between Galaxys.

brilliant project very inspiring , ideas that pop into my head watching this ... super conductor ( speed) , hollow metal ball , multi- levels tracks , tracks within a sphere

I am really excited to see this on Large scale.

I want to get a genius world record with your build.

I love this project! I wonder if it is possible to create a near 100 percent efficient device by adding more coils, thereby levitating the ball and preventing contact with the surface while going around. The timing would be difficult. Also, I wonder what it would be like if the ball were magnetized, and the track was a copper tube instead. copper tubes have very interesting interactions with magnetized objects traveling through them. The ball would be doing the same amount of work but at a much lower speed I assume. Anyway, this is three years after the fact, so my fascination is a bit late to the party. Great video.

Awe isn't that cute - your very own hadron collider!!

YOU SHOULD BE BUILDING THE 21ST CENTURY AMUSEMENT PARK RIDES!

Using a circular path is an extremely neat idea! I built a mass driver maybe 20 years ago but really it was pretty crappy. I'll print yours post haste! :-)

built one when I was 10 around 92'. History repeats itself

Wow cool! This track for the balls could be a tube with an integrated trapdoor. With the right timing you'd have an effective centrifuge launcher. Pew Pew Pew!

A 4p motor with a rotor so loosely retained that Saeco and Timken left the chat.

Nice. Gyroscopically fitting for a seat in the center. Like the ol aeloyphle on the kettle drum.

I'm a new sub. First video of yours Ive seen. Well done.

Bro looked at that cat toy and thought "hey but what if science?"

it would be pretty cool to see a scaled up version with like 16 coils and a 15mm steel ball, would draw quite a bit of power and be pretty big but it would be fun to see the small ball move pretty fast.

Teflon coating on the track will make huge improvements.

It's so hypnotic to watch!

Я счастлив, что нашёл ваш канал. Всё очень интересно . Спасибо!!! Какую программу 3Д вы используете?

I dont know why but this is sytysfying to watch.
