45v O/C doesn't really mean anything of course, but judging by the comments lots of people like it! Next Robert should do a van der graaf generator and 'generate' 20,000V....

You started the video with pulling a string and ended it with pulling a string. Love it. With that voltage it makes it practical for my 12 volt off grid system. Love this one.
@@ThinkingandTinkering Things that make no sense to me 🤔 Have a you tube channel where you make generators... with a 3 D printer. 😂 40 % of the peeps in my area are off grid, I don't know a single person with a 3 D printer, I've been off grid 8 years now. Now make generators with welders and grinders like actual OFF GRID People live and I'll follow you, like you used too.....
Such a great design! 44 Volts out of a plastic flywheel is great. I'm sure you thought of this, but what about putting another serpentine coil on the inside? Make the magnet flywheel shaped like a jar lid to allow room for the coils to generate off of the reverse side of the magnet. Two side of a magnet, double the potential!
@Robert Murray-Smith Maybe that could be a future video? If so, I can't wait to see the results!!! It would essentially be a dual power source. Add a third on the bottom, too!
A wacky idea I have for a generator is to have a hollow torus with ball magnets inside and wire winded around the torus. Then there are a number of ways to move the inner ball magnets, one being with another magnet that rotates around the perimeter. As the balls move through the hollow torus, the magnetic field will induce a charge in the coil wrapped around the torus. What do you think?
@@ThinkingandTinkering - I was a protyping tech, building functional proof of concept models and electronics to sell ideas to customers before retiring. I 've wanted a 3d printer of my own since they were $10K monsters that sat in closets in the bosses office as a trophy to his importance. Since watching your fan/generator video I had some some ideas to add some teflon low friction parts (blade carrying shaft and horizontal disks above and below the blade disk and glueing axial.disk magnets on it and the coil/ magnet fixture to levitate the blade assy to reduce friction. The printer is now on its way. You"re so bubbly and full of enthusiasm. I would have liked to have been the guy who built your ideas for fun and profit.
Interesting and by moving the magnets to the horizontal position you have moved more of your mass to the outside edge at least slightly improving the flywheel effect.
I'm loving learning from you! Thank you so much.... I've always felt electric is my weakest subject. Though I've always been a inventor of sorts... you are giving me info that I can understand...
Fantastic Rob. Way to show there's always room for improvement without making it more complicated. Looks like my werly birds are getting a makeover 🤔......
Amazing lil thing! Now with opposing magnets on both sides of coil. N on one side S on other. Make a hollow cavity for coil or sandwich it between plates.
Funny, this is the close to the design I was thinking of for a generator inside the Darwin wind pipe. Imagine a number of turbine blades with a ring around the tips - like the small helicopter toys - around the ring are the magnets. Blades are inside the pipe & free to spin on either a central bearing or with support around the ring. The coil is as you have it here but around the outside of the pipe.
great work , now attach an outer rotor to the inner rotor so that the serpent coil will be sandwiched in the middle between two magnets and check if the output will be doubled with lower rpm's . All the best .
no - it won't - the output doesn't depend on the number of magnets beyond a level - it depends on what force is input and what the efficiency of the machine is
@@ThinkingandTinkering physically higher magnetic field means more efficiency on which same output power with lower rpm, i am talking after reading some really deep books in this field or i might be wrong hope not , all the best , it is a huge breakthrough since your first video about turbines generator.
That's probably the best homebrew generator demo I have seen yet. Awesome result! 45v from such an easy design is impressive. Just one question; why no read of current & voltage drop under load? would only take another few seconds to do. The curious amongst us are left itching for the overall wattage.. What RPM did you get with the (ingenious) ripcord PM? Surely you have an old tachometer knocking about?!
rough guess of around 700 +/- 40 rpm. figuring ~6ft cord (~2m) , a ~2in spindle, and around one second for him to pull the cord. My math may be wrong but the circumference of the spindle is about 6in. two rotations per foot, 12 rotations per second lands at 720 rpm. all of this is based off of estimated scaled measurements. Hopefully Robert will answer your other questions, but he does tend to take a while at best...
My tac meter said fast enough for a good reading. Robs using a thin gage wire for his coil. Notice that he tells you exactly how he made it. More turns means higher voltage. Using thicker wire means more amps but less turns of wire, so lower voltage. Best bet is build one and do your own readings. That's the world of TnT🤠
@@archibaldvonkranski8881 Agreed in part - however, some of us would be more inclined to replicate if we had an expected result to go by, to justify our efforts.. I do feel Rob is ever so slightly erroneous in this.. Thoroughness should be a cornerstone of science IMO.. whatever the cost may be. If I could see it doing an amp or more I'd seriously consider building one myself, as it stands, I know of other designs that would definitely do over 46w in this form factor, if I needed a DIY gen. like this. Often easiest to just whack some n52's in an old synchronous thing really. It's still recycling/upcycling, and no 3d printer needed. Most often the real thing is unparalleled. (premade PMA)
@@reeferbeleafer9912 I agree the ends should justify the means and cost. Robs not offering a magical solution to your/the energy crisis. He shares the concepts and blue prints. I'm an Australian so solar beats most mechanical generating hands down. We still rely on coal for majority of our power tho. Watch the last 12 months of robs videos and you'll find he's not the solution but you are.
I believe that the weight of the magnets already contributes to the simalar effect of a flywheel. Based on what you explained here on top, I cant help to conclude that regtangular or even a square magnet might even produce more and stronger magnetic flux, that can also be concidered the maximum use of the space in the flywheel for the purpose of the wire. This was truly impresive.
Thank you very much Robert and Luke!! Awesome video , as always!! Now,,,, I have to find someone who Owns a 3D printer!! This has started the Old Gray matter agitating!! Yay 🎉 Thank you again!! Andrea and Critters.. ...XxX....
I've had some success at printing my own bearings and bearing housings for use with air-soft pellets and buckshot pellets, with the idea being "how can I......in a post-apocalyptic world?" I'll make a video about it someday, but I thought you might be interested. It got my gears turning. 😉
Thinking in terms of fly wheels, if you place the (rotor) magnets on the outside and the (stator) coil on the inside, you can get more magnets and a greater weight ratio for the rotor. The magnets would be held in the rotor by centrifugal force. Additional weight can be added to the outer rim of the rotor as well. Well done Dr. Smith. I love this design.
@@ThinkingandTinkering Id pull magnets out of old harddrives. I only have several hundred drives on my shelf from my computer recycling days. Can you say teck pack rat. Each drive is 2 lbs aircraft aluminum.
I think you could get up and down sections even straighter (more straight?) if you made plastic separators in the form of up and down facing alternating triangles or trapezium shapes instead of rectangles. Like V A V A V A.
Rob, we need to bottle your great facility with explanation, and that boundless enthusiasm! The next step is to get yourself a decent microphone, and perhaps a smidgen of home brew acoustic engineering ....
I do have a zoom H2n mate and I used to use it but I got the same comments - I suspect it's because I am not in a studio rather than the quality of the microphone
cheers mate - good tip - I do know it an tend to print rough as I want the prototype quickly - I would use the tip in more finished machines not in ideas I am still working out if it was me
I built a generator out of an old ceiling fan by installing rare earth magnets around the edge and i get that level of voltage out of it just spinning by hand.. I'm not sure they use serpentine wingdings but i suspect its that way... great video again TnT
Very nice! Please let us know the number of turns and the wire gauge that you used. The deep groove bearings used as radial bearings can take a bit of thrust as well. You could probably eliminate the thrust bearing. A heavier load would bring it to a stop sooner, but an impressive amount of spin time nonetheless.
hello Robert, i would suggest one small but arguably better improvement: printing a rotor so that the magnets are outside the stator, rather than inside, would increase the speed at which the magnets are passing over the wire and it would eliminate the chance of magnets flying off the rotor, due to centrifugal forces. on the other hand, you could increase the power output density if you print multiple wire-holding rings, for example, in front and behind the magnets so both sides of the magnet are being exploited
This is awesome :D thank you for this video :) You are very close to making my dream “magnetic planetary gear”… instead of a single internal rotor with magnets, create a middle rotor with “modulators”, and an internal rotor with magnets. Run a Dc current, and there will be a rotation reduction or multiplication… run an Ac frequency, and there will be an addition of rpm 😮
Your videos have always been great, but the 3D printer has really sped things up over the old days when everything was chiseled from granite. I really enjoy your channel. Have fun.
love your videos and laughter, i am a self learned tinkerer and was wondering how these would work in an actual generator setup. also if these would be stackable to form a compact but powerfull portable generator.
Good one. Your axial mighty mite used the same principle: the nails were at 90º to the wire, and were alternately polarized by the magets (reluctance?) on the rotor, even while they ran their field parallel to the wire in between. I think that your axial stator could achieve the same by adding an iron core to each winding post: the field would cross each wire, then magnetize each core at 90º to the wire, then cross the wire again.
LOL Robert, I love it when you find something impressive, your Mad Scientist laugh comes out to play lol. Keep expecting you to scream "IT'S ALIVE!!" Amazing work, thank you for what you do
I hope one day you incorporate of these designs into one artistic design or practical installation. I imagine a workshop with hundreds of different style generators on top. This one would pair nicely with the Darwin wind generator. In order to stack these, you would need driveshafts nested inside one another (tubes/pipes). I think you should try out laserhacker/lasersaber ‘s design of the stubble field coil with aluminum wire and an alternative to Cotten wrapped copper wire
Wow that really is a big difference . I wonder if the coil can be wound the same but adding 3 times as much but in a way that it sticks out further at the sides . It will make the circumference bigger but may add another 80 volts or so .
@@ThinkingandTinkering yeah sure but what is the point of diminishing returns ? How far does the magnetic feilds strength cut through the wire . Half inch or 1 inch . I am thinking less than half inch from my play with the attraction of this size magnet .
Just a thought from nova scotia. That is the best. Now here is my humbly submitted upgrade. Could you create a second ring of magnets and mount them in a fixture around the outside of your coils, and then some how rotate the coil or else “gear” the inner and outer magnet rings together. Wouldn’t that then put the output through the roof! Be safe and keep up this very interesting theme. Brent ( a retired “tinker” )
Congratulations! Now something popped up my mind watching this video 3 times. You have your conductive ink. Could you roll it up on a printed page with this same principle? That would be a printed stator without copper. Don’t know if I’m clear enough to express what I mean.
if you make the center a little lower and add the flat wind wheel you made last week(?) it would be a very compact wind generator.. of course you would probably need a cover for the coil... this one almost makes me want to get a printer!
@@ThinkingandTinkering What if the magnets on the rotor are all South Pole and there are North Pole magnets behind the twisted serpentine stator, surely this must have some effect ? It is like moving a wire down an endless magnetic flux ? Or is my whiskey too good ?
I missed this episode, don't know why. Tell me anywhere else you can go and learn and have such fun as this - I dare ya ! That laugh is so dirty .... it should be sold by the pound 😆
Absolute Great!!! :o) Soon I send you a parcel - it may be useful to combine the content with this awesome generator. Still testing and optimizing my "thing", but nearly finished. Cheers, Fred

add regenerative braking to recover some of the generated energy so that you can keep it at a near constant spin speed.
Now that's a Real Radial flux alternator.I like where the tape is, great idea.😊
cheers mate
This coupled with your flat winddisk is viable ,practicle and simplicity in motion. Make a prototype and I will be buying in!
hello Robert, i would suggest one small but arguably better improvement:
printing a rotor so that the magnets are outside the stator, rather than inside, would increase the speed at which the magnets are passing over the wire and it would eliminate the chance of magnets flying off the rotor, due to centrifugal forces.
on the other hand, you could increase the power output density if you print multiple wire-holding rings, for example, in front and behind the magnets so both sides of the magnet are being exploited
I really enjoy watching your videos. Thank you
indeed
I love the way he bursts out laughing when something works
Brilliant....I need a crunchie now.
and who doesn't lol
This is awesome :D thank you for this video :)
You are very close to making my dream “magnetic planetary gear”… instead of a single internal rotor with magnets, create a middle rotor with “modulators”, and an internal rotor with magnets.
Run a Dc current, and there will be a rotation reduction or multiplication… run an Ac frequency, and there will be an addition of rpm 😮
🙆♂Brilliant work Rob! You're Awesome! ⭐⭐⭐⭐⭐
cheers mate
Your videos have always been great, but the 3D printer has really sped things up over the old days when everything was chiseled from granite. I really enjoy your channel. Have fun.
it really has lol
Interesting take on the generator, Robert. I sense you're homing in on something that will actually use Lenz' Law to your advantage. All the best.
cheers mate
love your videos and laughter, i am a self learned tinkerer and was wondering how these would work in an actual generator setup. also if these would be stackable to form a compact but powerfull portable generator.
He's already made one. It's called the wind wall. Check it out ☺️
He used pc fans and poly pipe but incorporate bro😎
already done its ate - it's the wind wall series
Would it make sense to do psudo magnetic levitation here like in video 1450 instead of a bearing?
Good one. Your axial mighty mite used the same principle: the nails were at 90º to the wire, and were alternately polarized by the magets (reluctance?) on the rotor, even while they ran their field parallel to the wire in between. I think that your axial stator could achieve the same by adding an iron core to each winding post: the field would cross each wire, then magnetize each core at 90º to the wire, then cross the wire again.
well spotted mate - yes it did
I think this might be a good upgrade to the whirly-bird
LOL Robert, I love it when you find something impressive, your Mad Scientist laugh comes out to play lol. Keep expecting you to scream "IT'S ALIVE!!"
Amazing work, thank you for what you do
lol - now I am tempted lol
@@ThinkingandTinkering ROFL :) Keep it up mate :)
I hope one day you incorporate of these designs into one artistic design or practical installation. I imagine a workshop with hundreds of different style generators on top. This one would pair nicely with the Darwin wind generator. In order to stack these, you would need driveshafts nested inside one another (tubes/pipes).
I think you should try out laserhacker/lasersaber ‘s design of the stubble field coil with aluminum wire and an alternative to Cotten wrapped copper wire
I like the idea of paring this with a darwin
Thank you for the explanation and all of your wonderful content
cheers mate
Wow that really is a big difference . I wonder if the coil can be wound the same but adding 3 times as much but in a way that it sticks out further at the sides . It will make the circumference bigger but may add another 80 volts or so .
or use thinner wire
@@ThinkingandTinkering yeah sure but what is the point of diminishing returns ? How far does the magnetic feilds strength cut through the wire . Half inch or 1 inch . I am thinking less than half inch from my play with the attraction of this size magnet .
Just a thought from nova scotia. That is the best. Now here is my humbly submitted upgrade. Could you create a second ring of magnets and mount them in a fixture around the outside of your coils, and then some how rotate the coil or else “gear” the inner and outer magnet rings together. Wouldn’t that then put the output through the roof! Be safe and keep up this very interesting theme. Brent ( a retired “tinker” )
yes you could mate
Very nice Robert, thanks for sharing 👍
I am glad you liked it mate
Superb Rob 😁👍, that damn laugh mate.. everyone could be so excited about science
lol - yes they should - it's awesome lol
Damn Rob. 45v thats nuts. Seriously, I'd love to see it recharge a dead car overnight
it is pretty cool
ripe cord pulling for day's, to load a Car battery..
Congratulations! Now something popped up my mind watching this video 3 times. You have your conductive ink. Could you roll it up on a printed page with this same principle? That would be a printed stator without copper. Don’t know if I’m clear enough to express what I mean.
the ink has a very high resistance when it comes to this kind of work mate - it would work well in electrostatic applications
awesome generator. What was the power output in watts?
no idea
if you make the center a little lower and add the flat wind wheel you made last week(?) it would be a very compact wind generator.. of course you would probably need a cover for the coil... this one almost makes me want to get a printer!
it does need a cover mate - I left it off just so folks could see it but a cover or maybe potting would be a good idea
Bless you Robert
and you mate
Thank you. Awesome video.
That video makes me want to buy a 3d printer. Just for this project, fantastic video boys. 👏👏
cheers mate
This makes a lot of sense. It can go bigger and stronger. I am building one❤🎉😂
awesome - let me know how you get on an just to let you know I used 0.1mm wire and 350 turns
@@ThinkingandTinkering What if the magnets on the rotor are all South Pole and there are North Pole magnets behind the twisted serpentine stator, surely this must have some effect ? It is like moving a wire down an endless magnetic flux ? Or is my whiskey too good ?
I missed this episode, don't know why. Tell me anywhere else you can go and learn and have such fun as this - I dare ya ! That laugh is so dirty .... it should be sold by the pound 😆
lolol - cheers
Absolute Great!!! :o) Soon I send you a parcel - it may be useful to combine the content with this awesome generator.
Still testing and optimizing my "thing", but nearly finished. Cheers, Fred
awesome mate lol
wow, it runs and runs and runs.....unbelievable long.....thx for the vid.
Just bang your flat feather turbine design onto the hub and get yourself a sexy wind generator. It's funny how I've watched so much of your content that I've started getting that contagious diabolical laugh when my projects feel successful. Thank you for the inspiration :)
that would be sexy lol
this is, in my humble opinion, the best way to ( hand charge ) a supper capacitor. thank you so much :)
cheers mate
This is perfect for your vertical wind turbines. Can't wait. How do you design and print so fast? It takes me days and many failed prints, on allot simpler designs. It is great stuff pal.
Wow!!! That was outstanding good sir 😮👍
cheers mate
