6:15 by my observations all the coils look like they're on and it shuts the coil off just when the ball comes in range so that the coil behind it can keep the acceleration going. And this is mainly because the first try when you placed it in the track was immediately attracted to one side.
Thanks for the comment - after reading it I confess that you did make me doubt myself, so I just went to double-check! But my intial deduction was correct - obscuring the sensors is what energises them. So, generally speaking, there is only ever a maximum of one coil at once energised. If it appeared that the ball get attracted to one side when first placed down I think that was just because the track was not flat level!
@@PlayfulTechnology OK, that had me going because that's what it looked like. But thanks for your confirmation. Camera can play some tricks but this time it was gravity!
Great idea! I think this would fare well as a series in which you order many interesting and wacky items from China, then assemble them and show them in action. Seems like something that would attract views.
Combine it with an ir-sensor, an Arduino that counts passages and you have to find the ball bearings to make it count turns. I would change that hard plastic tube to something a bit softer and transparent. It could be a very simple and cool looking puzzle.
Just an fyi... This isn't a real cyclotron. A cyclotron is a particle accelerator that accelerates a charged particle through two half circles using a changing electric field. They top out at about 70% the speed of light which is when time dilation starts to kick in and desynchronizes the particle and the changing electric field.
Surprised only 6 out of 10. That works quite well! I would have given it an 8. Could be fun extending it and 3d printing a tubular track that had buildable segments.
I am kind if curious what would happen to make a 5x replica of this with a clear closed tube that has a larger metal ball in it. The tube will be a vacuum tube essentially, hence why it needs to be closed, and the tube will be vacuumed while the machine runs. This should make the ball excluded from nearly all force vectors except gravity. I know the ball will accelerate, of course, but i still think that would he cool to build. I wish i could build something like that. 😅
Wouldn't it be easier if all of the coils were all charged at once and the sensors turned individual coils off and back on again instantly? That seems more efficient than charging an individual coil and turning it off again instantly as is suggested in the video. Obviously, the circuit would have to be interrupted at some point, or the ball would be stuck at the center of a single coil. It just seems to me that turning the coil off rather than on would give more time for the ball to travel since the magnetic field extends well beyond the coil and sensor. Great video!
magnetic force falls off by distance squared so no, ideally you use all your amps for the closest coil but this little toy likely uses little current. If you had no current limit then you'd keep one half of the coils energized at a time.
I'm a former electronics engineering technician but I sell stuff now. I find most kits that require soldering have instructions but it is unclear in Chinese. I'm used to reading Spanish and German but Chinese is hard for me, I depend on OCR conversion. Being good at technical writing I occasionally have to reverse-engineer something and figure out in detail how it works, draw a clear diagram, and write assembly instructions from scratch before I sell the kits.
Electronics. It's more like a hobby now which also gives me an advantage in selling stuff. I have more diversity in the stuff I sell than most vendors I know do. I sell air-brushed and decorated pull-string travel bags, gemstones, rocks, radios that can DX far away, phone holsters, cables, chargers, bushman survival stuff and I mod flashlights. It's always fun to reverse-engineer Chinese-made stuff and then make a profit off of modifying it and making it better. I always have people coming back to buy 2 or 3 more. Electronics is just part of that diversity in the other stuff I sell. If you sell just one thing like electronics you won't make it, you got to take everything you are good at and sell it. There are a lot of good really cool products in China but there are also fake copied low-quality products of legit good quality Chinese-made products not just fake copies of German or American-made products. It's sad that if you have a good idea your neighbor can take your idea and sell it and even steal your brand name and logo. When I buy stuff I try to check that out because I want to buy from the creative person whom the idea came from.
It really looks like Iron Man's arc reactor.. The description was dodgy at best, so your explanation was appreciated, and I look forward to seeing what you do with it in terms of escape room puzzles.
I would use that with several balls as a hardware random bit generator, either by hooking it to a webcam and feeding sections of the video feed to a stream cipher or by adding sensors for the same purpose lol
Nice gadget! I have just made a ballistic chronograph using IR LED’s and phototransistors, similar to the gates of that gadget. Just need to work out the distance between the gates then work out the time elapsed between the in gate and out gate and you have the speed, if you had the weight of the ball you could then work out it’s energy too!
Loved the video. I'm glad it arrived in one piece xD that itself deserves atleast 4/10. But I'm still curious whether the infra-red is actually playing a part in causing the coil to energize? Because since each coil is connected to the power supply, and has current flowing through it, won't it be magnetized regardless?
That's a good question! If the coils were permenantly magnetised, what would happen is that the ball would just get attracted towards the closest one and then get "stuck" inside the middle as it passed through the coil, because that's where the magnetic pull would be strongest. Because the IR sensors are placed at the "entrance" to the coil, when the ball approaches them it gets pulled forwards towards the middle of the coil, but then the coil gets de-energised again so that the ball momentum carries it forward, rather than it being pulled back again. Like a slingshot.
Proximity sensor, to control when the magnet turns on and off. Each of those electromagnets uses a proximity sensor to time the "on/off" of the magnetic field. It's pretty obvious if you think about why they had to put the proximity sensor right on the spool of the coil and not further away. If you put a magnet flat on a table, and try to roll a ferrous object (steel ball, say, from a crafts store) past it, the object loses all momentum and sticks to the magnet.
I've also always wanted to buy those weird and wonderful online gadgets but the skeptic in me always interferes with my fingers clicking the 'Buy it now' button. You're a braver man than I Gunga Din! :)
I would call it more of a Synchrotron than a cyclotron, since cyclotrons do not accelerate particles in a ring, but a spiral path with each accelerated cycle from the Dees. synchrotrons do a ring.
Superficially it IS a lot closer to a synchrotron. But in neither a cyclotron nor a synchrotron are the particles accelerated by the magnets. The magnets steer the particles. The particles are charged and are accelerated by electric fields.
It's probably the sort of thing a school science department would have. I'd give that 5/5 myself. By the way, Chinese people don't need a 100 page manual to run a tap like the Brits seem to need these days.
Quick tip about the plug - China has use of the same type of outlet as the US (or near enough to be similar), so units with 120-240v input voltages work with the same plug in both countries. I believe in China it is their Type A outlet!
so test Number 1 outcome - As advertised Sherlock right? The demonstration is a Chinese kids toy to get the Chinese 5 year old to do EXACTLY what the toy did to you "Lets make an Earth Sized one Daddy"
If you were genuinely expecting a cyclotron, you'd be massively disappointed with this.... but you'd also be rather silly to expect you could get a cyclotron off Banggood.
If you're gonna build one, build one out of transparent tube and fill it with mercury. No ball is needed. The signalling must be done by a micro-controller like Arduino where you can adjust the frequency and pulse width of the signal to each pin, via 2 pots connected to the MCU. One to adjust the frequency, the other to adjust the pulse width. The loop is a round robin signal to produce the rotating magnetic field. Now that I would love to see. They say the weight of the unit decreases.
Si te hubieras gastado ese dinero en una muñeca de silicona por lo menos tendrías donde meterla, así solo tienes un agujero con una bola dando vueltas. 🤣😂🤣😂🤣😂🤣😂🤣😂🤣

can use reed switches and stationary magnets to do this without electronics.
That sounds a good idea. Balls would have to be magnatizd though.

i am very curious what will happen if track was hollow pipe n filled with ferrofluid, will it behave like some kind of pump?
I've also always wanted to buy those weird and wonderful online gadgets but the skeptic in me always interferes with my fingers clicking the 'Buy it now' button. You're a braver man than I Gunga Din! :)
I wonder how many marbles could be used with it?
It would have been fun to see how many it could use.
This might be able, to be made quieter, by using vinyl tubing, for the track. 😁✌🖖
Basically a linear motor in a circle.
Matchbox car people need to make something like this.
if the ball turns fast enough it will levitate ?
I would call it more of a Synchrotron than a cyclotron, since cyclotrons do not accelerate particles in a ring, but a spiral path with each accelerated cycle from the Dees. synchrotrons do a ring.

Hello, will it work with vertical position (Anti gravity direction) ?
Hi, am based in London, are you willing to sell the kit? thanks

So is this an infinite coil gun?
I wonder how many of these you would need to power an electric car

Can you make it go faster
If you were genuinely expecting a cyclotron, you'd be massively disappointed with this.... but you'd also be rather silly to expect you could get a cyclotron off Banggood.
You are a braver man than I using that power supply (and with a deathdaptor as well)
Lol. This PSU was one of the sturdier ones I've seen!

Sadly that won't work, since Mercury won't be attracted to the magnetic coils.

Why don't we take advantage of the earth's magnetic field to build airplanes, fly by magnetic field
Well done, do you have a scope and a shunt resistor and can measure, how much energy a ball transfer draws from the power supply ?
Many thanks.
