Electromagnetic Accelerator Improvements Part II

[@HyperspacePirate]

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.

[@G0ldmoon]

Hey, I always imagined something like this for a "gun" type design, where the shape of the "gun" would be a 6 or 9 with a gate at the junction of the neck of those numbers. when you wish to fire the "gun" the junction would open, turning the circle design into a open barrel design. What are your thoughts, would it be possible to open the junction accurately and quickly enough to allow for that, with the 6/9 design I'd imagine centrifugal force/centripetal force would accommodate a lower angle of turn, pushing it to the new lane which would essentially be the barrel. also plumbers tape or teflon tape is cheap and easy to access, and cheap to reduce friction. lastly look at stuff used for liquid cooling PC's there are acrylic (plexiglass) or PETG (polyethylene terephthalate), they are full tube's and will have less imperfections and blemishes, and you can get better tools to shape them perfectly. using fittings to build rigidity.

[@stevemeacham6880]

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.

[@ddegn]

That sounds so cool! I'd love to see a video of it in action. Those sparks sound like a lot of fun. I just ordered a bunch of magnet wire and 1" ball bearings myself. I plan to go the opposite direction and use a microcontroller. I'm planning on using the microcontroller to optimize the timing of the coils.

Tablet slipped while typing, oops…YES. Mine was meant to be like a rail gun in a loop. I had considered making a segment that could open the track or at least the middle rail, and allow the projectile to escape (shoot), but never did. As a projectile launcher, it wouldn’t have been that good. I measured the speed to be around 120 m/s IIRC. That’s about 1/3 the speed of sound, so way slower than most real guns. Also, accuracy would’ve sucked because of an unstable round ball. But, it still merited a safety shield for the operator. It didn’t work perfectly. The idea to open the track may have had some inspiration from bad runs.

[@BlinkRepeat]

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.

[@coccoborg]

Depending on speed and code efficiency, a microcontroller may just not be fast enough. An analog circuit is only affected by propagation of the signals, rise times etc... In a digital circuit with microcontrollers you have processing happening on top of all the rest and it adds lag.

[@Yranax]

@@coccoborg the most uC are more than fast enought for this aplication, 210MHz should be totally overkilled and thats still not the fastest uC.

[@teddycook1299]

@@Yranax you’re quoting a clock speed which is useful for knowing how a system will handle heavy loads. This kind of data processing is extremely light and I/O latency is a more relevant figure, which has nothing to do with clock speed. Any microprocessor, no matter how small, will be significantly more latent than an analog circuit.

[@Yranax]

@@teddycook1299 im in electrical engineering for over 20 years. And the time constant of this system is dominated by the mechanical properties. A uC is way faster than the hole system, even faster than the power switches that are used. So there is no problem with latency. An analog circuit could do the job, but a uC will be more convinient and has the ability to controle complex tasks. It is almost impossible to create an analog circuit, that will position multiple balls to a wanted set point. Uc will do the job and even more. and 210MHz are just a number, right. the rise and fall times could be way faster. And another thing to mention, a uC hase some handy peripherals. For example, an ADC in combination with DMA and PWM could controle the hole system. There is no complex calculation to be done to controe the inductors, so there is no advantage in using analog circuits.

[@anventia]

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?

[@electedsphinx4086]

It would quickly fail and send all 4 balls around making it extremely unstable, we built electromagnetic accelerators in stem when I was in highschool and tested multiple applications and variations it was extremely fun and knowledgeable for us engineers, i remember trying Newtons cradle and it only worked on the one we built in a diy vacuum chamber

[@downflatdown6604]

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.

[@RyanBarnes]

Came here to say exactly this. The coil modules add that bit of straight that cause the ball to travel in a short but straight line. This causes the ball to impact on the track losing momentum. Could the coils be designed in such a way that they could slide over your track segment rather than be an extension of it?

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 .

[@prestonrodenkirch8412]

A fully enclosed tube filled with mercury is my theory for levitation. Maybe have to do 3 units arranged in the 3 spatial terms x,y,z at right angles to each other like a gyroscope. At the very least it would produce an effect on the inertia of anything it would be attached to.

[@DrLuke-lp5vz]

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.

[@Br0nyAn0myn0u5]

I think your idea could work better if it was instead two sensors for each coil that calculated the velocity of the ball and then determined the best timing for the coils.

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.

[@braysniper58]

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.

[@repalmore]

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.

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)

[@TheSwissGabber]

but is that really simpler? you need a current sensor / source for each coil, and a MCU to process everything and you need to calibrate the whole thing.

[@tiemanowo]

Yes, I agree. Maybe not entirely "simpler" but we are trading 4 IR diodes, and 4 IR detectors and cables to connect them (8 pairs of wire), for a "current detector" for each coil. So.. yes, maybe not "simpler" for everyone.

[@johnrobholmes]

Can be controlled with analog on it, but the inductance of the coils will limit detection speed vs ir sensors. I'd be tempted to use hall sensors and build an all south pole magnet ball to pull through the track.

Advice for version 3; place 4 more sensors halfway between the the axis of the magnets.

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!

[@HyperspacePirate]

Thanks. I've played around with this factor on a coilgun and found there's an optimal series resistance with the flyback diode to quench the coil current faster (damping ratio or some such). One of the more elaborate schemes I've seen was one where the flyback diode current was dumped into the next coil. Seems a lot more efficient, but more complex to design

[@ridefast0]

@@HyperspacePirate This is a fascinating EE problem because the inductance changes as the ball goes through! So we have the unusual luxury of the full derivative E = d(LI)/dt or in its full form E = L dI/dt + I dL/dt. Looks like a job for circuit simulator software.

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!!

Only limitation is material stress would only take so much centrifugal force before the ring shatters , so in theory if the outer ring and the moving pieces inside it can be influenced magnetically to spin , with enough force it would counter the center weight and it’s own weight , meaning less fuel and force needed to propel or take off .

[@mpwmscog300]

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

[@TheBarretNL]

If this could be the spinner and another mechanic that could shoot it, that be interesting to see how powerful that is, but you need a counter weight for that spin and ball ofc.

[@Jokerwolf666]

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

[@R4mzyCoZa]

who needs stability. that wobbly motion might make an interesting device in a roomba-ish form factor, maybe a cleaning/polishing tool or bot. could one influence direction by timing pulses to those coils in the direction you want it to move (or on the opposite side if it's more a "pushing" thing)? all it needs is a flat housing and wheels...

[@nathanielblairofkew1082]

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

[@nathanielblairofkew1082]

Could also be used to minimize size of a rail gun to a pistol form factor

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

[@behemoth6sic6]

My brain: I wonder if it's possible to use mercury instead of the balls in an adaptation of the design.

[@vladimirenko]

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.

[@HaveAGreatDay54]

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.

[@thankthelord2606]

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

[@ghooustsilvr2162]

If you use a circular tube and connect 3 disc-shaped figures, you can create a magical effect such as the movement of the planet Earth. How to install the discs: One must be inside the second. Of course, the first disc must be smaller than 3.

[@ghooustsilvr2162]

Note: It is recommended to connect the first discs to the second with two intersecting points diagonally, and the second and third also diagonally, but the two diagonals must be opposite because the movement will generate rotation of the disc on the diagonal as an axis. I will leave the rest to your imagination.

[@topherteardowns4679]

the brightness of the room will still effect it, the IR leds dont matter, its the LDR that does. but, to avoid that issue, you could use a different form of triggering. I foolishly wrote a comment on your first project without watching this one, but, the same thing I mentioned there would be applicable here. (mosfets may not be getting turned on 100%) also, with the gate capacitors, they may be getting slowed down while turning on because of the input capacitance of the fet having to be charged up (miller capacitance) Kick ass videos sir.

[@CzarYe]

Teflon coating on the track will make huge improvements.

[@_its._gaurav._]

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

[@vst12]

Cap the top do you can harvest the cinytifical force, you might be able to get lift if you can control the speed the magnets are going off, possibly finding a slicker surface for the inside or a high temp paint

[@Travelbeatcreations.official]

This principle is relevant for the future of flying.

[@jamespsyfer]

If this is powered up more…. would it produce anti gravitational effects? A helicopter has no wings… but the uplift I would assume is created by the great gyroscoping blades ?? This device clearly has motion … how could lift be obtained?The energy created could in theory be translated into lift?Does the ball have magnetic properties and what if it did? What if you opposing field interactions? Could the fields be bent in some way as a result of electromagnetic interplay??? Will you try these things and report back please. In the same way magnets can repulse, can this repulsion be optimised and be kind of propulsion??? I hope you toy with these possibilities. Great project 👍Could the centrifugal type force be some how made to push down wards? It’s rather frustrating… because basically it’s looks like the outward force is sufficient.. if push downwards… to make your device hop upwards a little. I’m sure you are on to something

[@Anonymous-xp2sx]

I know this videos a year old but just because I’ve built a few structures or two saw a couple points I’d add some extra bracing so you can reach greater speeds , partly the reason why the hardon collider is underground so it doesn’t move. Just food for thought not hating love the work.

[@ArrowStudios]

if you do a 3.0 maybe try improving the smoothness of the track aswell as adding a ridged top lip to help with the fly away balls. also consider mounding it to a weighted plate for 0 movement when in use

[@maddoxinc1642]

What we need is a large 80lb block of steel with a nice raceway milled into a circle and polished. I wanna see how fast we can get that ball to go.

[@peterfoster9456]

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

[@thomassmit9944]

Would be nice to have a state estimator of the ball position based on the EMF of the ball passing through the magnets. Then you can tune the phase between ball and magnets to optimize the acceleration of the ball. Add another ball to balance the system.

[@phisit8813]

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

[@jessiejanson1528]

id like to see -a stiffer rail for the balls so it doesnt deform as the balls travel through it. -some kind of alignment tool for the track so the joints are smoother or 3D printing a solid track so there are no joints. would make the winding part more annoying though.

[@justrad7637]

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

[@JMPDev]

Would have loved to see you try the magnetic ball from the first video on this

[@versys-research-vietnam]

Solution for faster acelerator is the time that next coil will be turn on, that can base on the time ball travel from coil(1) to coil(2) => speed +guess speed after coil(3) => coil(4) turn on and loop for coil(1) - coil(3), just what in my mind, i have enough component to make it but i dont have time :(

[@ufopolitics]

Hello, Excellent build!! Now, can I ask you to perform one test? Can you build two identical prototypes with the four coils/four sensors...and then attach them by the center, make them (the steel balls) rotate opposite to each other on each unit... I believe they (both) would stabilize together...then just set the whole assembly on a weight scale... I am almost certain the assy will lose weight the faster it goes. Thanks for showing such incredible test!!

[@DJGive420]

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

[@ferropoly]

Please put it on a very sensitive scale. Measure it before operation and measure it during operation. I think there will be some anti-gravity effect.

[@Ice_elite]

The cats are slowly becoming more advanced

[@angst_]

With a pair of IR sensors per coil you would be able to estimate the speed of the ball and adjust the trigger threshold/timing accordingly. It would of course increase the complexity of the control circuit. You could maybe do it with the 4 sensors you have now using them to estimate speed between coils.
