@@ThinkingandTinkering How to determine the length or width of the jib bolts for building/winding the coil?
I don't know if you'll ever come up with an item that people will say "Yep, that's the one I am going to build", but the real prize watching your videos is the education and inspiration. I truly believe that you are getting people thinking about how things work and how every aspect could possibly be improved. I've always been into physics and electronics, but I feel that I have a much deeper understanding of these areas having watched your videos. So, thank you Rob, for all that you do.
The rose generator is my "I'm going to build that!"
When SHTF, "Makers" are going to be the best off. 👌
This is one of the ones that I am definitely going to make. I have multiple printers with octoprint, and I am sending the sliced models to them now.
I'm going to have a go at a variation of this generator. I hate resin and winding coils so I really like the less is more philosphy on this. For small wind the efficiencys are miniscule anyway.
lol - cheers mate
You have absolutely the best mad scientist laugh because it’s so full of genuine joy instead of malice!
Truly intelligent people, take the hardest concepts, and explain them in the most simplest, logical way. Thank you so much sir😊.
Hey I’m all the way from Sri Lanka (Ceylon) I’m actually a photographer but I built my own cnc machine thanks to people like you who share knowledge. Was never a A grade student but I love experimenting and creating stuff. Thank for your inspiration Wish you great heath and a beautiful life as well say in Singhalese Ayubowan
Keep it up Man 👍👍👍.
"45 Volts!" Robert cackles maniacally, with good cause! Well done!
cheers mate
I look into battery Chem, I find your channel. I start making little hobby generators, I find your channel. I start printing homemade generators and look for designs, you're here again. I wish UA-cam would actually notify me when you uploaded so I could find your things sooner, you always make the best content.
wow cheers mate - I think there is a little bell you have to click if you want notifications
You've actually got me ordering an Elegoo this month thanks to all these videos mate! Some great explainer over the past couple of weeks and it's been fun to see the evolution. Looking forward to trying to put together some of the best best elements together as one full build (once I get to grips with printing). I will of course give you a full credited update with whatever I manage to get together! Thanks as always!
I don't care about credit mate I just want to see what you do I am sure it will be awesome give me a heads up will you cheers
Please Robert, put on a load.
Or charge a battery wind power overnight.
Then the possibilities will be realised.
Cheers
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....
The machine he uses has a static load
@@hive_indicator318 yea he got it because of these comments
The meter he is using has a built in load, listen to the previos videos. He GB ives you the make modle and loading built in. He thourough and tries not to be dull and repetitive.
@@chriskelly4619 Well I kind of agree that voltage does not say anything without knowing the resistive load or the actual power draw. Just slap a power resistor in series, tell us the value and everyone is happy.
i JUST LOVE WHEN YOU MAKE SOMETHING ULTRA BETTER THAN WHAT YOU MADE BEFORE ROBERT. THIS IS WHAT PUTS A SMILE ON MY FACE, USING ONE'S MIND FOR THE BETTER.
This is what really irks me to no end with items for sale in the marketplace Seems making headway with technology is a dead art form.
Good video with great results.
thank you mate and I am glad you liked it
As ever educational, entertaining and inspirational- and making physics fun is no mean feat!
Excellent demonstration of applying first principles thinking. You are an awesome physics teacher!
cheers mate
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.
@@reeferbeleafer9912 it's not hard to make these things out of stuff you can find laying around. Give it a go😎
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!
it's a good idea mate and you are quite right I have thought about it lol
@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?
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.
cheers mate
@@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.....
Legend👍. I love watching your videos. There's always so much food for thought. You're a natural teacher.
Watching these generator videos avidly. Getting better and better!!!
cheers mate
Feels like i'm back in school again.
but with the coolest teacher 👍
lol - cheers mate
Wow! Outstanding once again, Rob.
cheers mate
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.
Tapered bearings similar to car wheel bearings would be a great alternative to running a standard bearing and a thrust bearing.
0.1mm and 350 turns
@@ThinkingandTinkeringI’m assuming that’s about 1w?
I love how you’re nearly 2000 videos in, and still laugh like a maniac when it works :)
lol - well I like it when it works lol
The video numbering system threw me at first. "Wow! They did this in 1869?" LOL ;-)
Thank you. lol few hours after watching this I'm half way to finish making one. hopefully getting decent volt too.
I only stumbled upon your channel.a few months ago but you've already inspired me to buy a 3d printer to bring your and my imaginations to life.
oh wow - awesome - thanks for letting me know mate
@@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.
yep
Hello Robert!
Why did you use only one side of the magnets? If you use two coils, one under the magnet and the other one above the magnet, you may come up with double the output.
Only my 2p of thought for this. The difficulty did not even rise.
So have a nice day and weekend, while I am trying to build an actual windcatcher on a pipe.
Sincerely your magicworx
You hit this one for six, Rob! Love the design!
cheers mate
That was absolutely amazing how much power you got out of that little thing by spinning it like a top.
We have no idea how much power it is putting out! Voltage is just potential, we need the amperage to calculate power (watts)!
for sure mate
outstanding you gave the serpent a big "KISS" well done and thankyou for sharing
cheers mate
You have convinced me to use snake oils for my next, new, latest labors in mycrohydro madness!
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 🤔......
awesome mate - it occurred to me too that roof whirlybirds could be easily adapted to generate with this idea
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...
Always Impressive Robert .. amazing what you have been doing!! You are great at teaching the world.
wow - cheers mate
Amazing enthusiasm for a simple subject 😊thank you
Truly magnificent sir.
thank you mate
Thank you for the very informative video series. I'm bowled over as this is EXACTLY WHAT I NEED 👍👍
How many windings have you put on the serpentine coil please?
All your videos are perfectly understandable. Thank you.
Absolutely outstanding Robert. Thank you so much for these posts.
cheers mate
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
Add some weight to it for more flywheel effect Rob. Absolutely brilliant.
Thought!! Would making the plastic formers iron, ie giving it an iron core, improve it further?
yrs it would mate but it would also introduce cogging and raise the start torque
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.
indeed
Hi Robert, I following your studies about serpentine coils and are amazing! I have a question.. It’s possible to windibg serpentine coils in a 3 phases set up? Thinks yes but how we can fix it in a rotor to have a good efficency? I’m talking about the gap space between the magnets and the coils… sure that in a good way to doing its but it will be grest if you can explain your point of view about that. Thanks for everithing you do!
I'm printing a copy of the stator, I shall be able to play with it this afternoon....Thank you.
Nice leet me know how you get on cheers
That's brilliant! Also really shows the advantage of speed at the rim.
thank you mate - I think it does too
awesome generator. What was the power output in watts?
no idea
Awesome, I wonder how it will perform with the gear system you developed instead of the string... this way its easier to keep it spinning with gears and handle... can you combine, I think it will result in a real life generator to charge super capacitors in series as the output seems substantial.. thanks.
it would be great in that
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.
I am not sure mate - but interesting tight - thanks for sharing
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....
lol - bless you Andrea
Bloody marvellous Rob !
cheers mate
Rob there’s a way to make circular part more smooth in tinkercad. Just set it to 60 sides then copy and rotate by 3 degrees, 1.5,.75,.375 then group
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 love the Twisted Serpent. 😄
Quick question:
Would this produce more current if the magnets were closer to the wires ? Just wondering if the magnetic field is impeded by needing to pass through the plastic. Thanks
Plastic won't affect the magnetic field any worse than the air gap, but the distance does. Closer the better.
no - it will produce more voltage - but only because the magnets are closer - the strength of a magnetic field is proportional to the square of the distance - the nearer they get the stronger the field is and as a generator works with BLV sine theta - emf would go up
Awesome 👏
Great masterclass, interesting and easy design!
Thanks mate 🌟
thank you mate
Would it make sense to do psudo magnetic levitation here like in video 1450 instead of a bearing?
This is a wonderful design compact, cheaper, better.
Would like to know - How many turns per coil?
Where can we download the file to 3d print the parts
Thank you
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.
Getting the wire onto the stater must have been fun. (having the length to allow you to get the last turns in place, would leave the whole thing rather loose. 45v! awesome! How many watts do you think it could generate?
Inspirational, fun, and a joy to watch🥰
awesome lol
Awsome Device Robert, What printer do you recomend for type of work.
How many amps is that able to supply without overheating? I like it better than my piggott axial flux.
no idea mate - whatever the wire can handle
Happy Spring! 🎉
I love the way he bursts out laughing when something works
Hi Robert, Your a master of learning
Great work... and also much better voltage!
for sure mate
Hey Rob. I love this stuff. A quick question: is there a relationship between the number of twists in the serpent and the magnets? 1:1?
Anyone else read the title screen as "Thinkering and Tinkering"? :) Thank you for another lovely video.
lol - I haven't if that h helps lol
question ,it coul be a good a better one than the axial flux or not?
Robert, I love your videos and enjoy being challenged to think about improvements. How would adding a second row of magnets on the outside of the coil affect the efficiency or power output? If the magnets are close enough to each other to begin attracting to each other and you move the wire between then, isnt that the best situation for eddy current generation?
Hi. Thanks for educational videos.
I am trying to find the thrust bearings you have, but I can't find the 22x35x10mm. Can you please provide a link to the one you bought?
I really enjoy watching your videos. Thank you
indeed
That is legendary!!! What's the copper wire thickness?
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
Thanks mate. That was exactly what I was hoping you would do. Looks fantastic. Cheers!
cheers mate
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 :)
That is an awesome design! Well done sir!
cheers mate
Having seen a method for serpentine wire layout, this has given me an idea to achieve something. However how do I find out the flux density of the magnets being used other than by a magnetometer. Is there a list for that for neodymium of a given size?
Given you have shown two methods of coil layout as in horizontal and vertical (the latter being eminently suitable for scaling bigger), which method do you find best, or is there little difference?
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 .
So Robert,when are you going to scale something up that can be practical to use, for say powering an average family home? Or charging a battery bank for said home?
I think a practical use for Rob would not be to scale up the size, but scale up the quantity. Cheap and easy builds working together
The predecessor of this video, the flywheel flashlight, is a practical solution for emergency lighting. It's better than the crank flashlight I bought.
He likes making small projects that are small enough to be cheap and accessible. If he scaled up e.g. stacking the savonius turbines (one of the easiest quickie projects) to make a 10x6 wall you'd have hundreds of hours of 3d printing, a large frame that would need to made of steel and with real bearings, many hundreds of dollars in magnets, and a couple of miles of wire to wind into coils. Instead of a project that hundreds of people can do for $10 you get a project 1 person in a million might do. Scaling up is hard.
It would be neat if there was a shelf or table with all the models on display and connected. Like adding new additions to a train table.
powering a home or charging a battery would be quite the system... that's going to require some massive power. I did see one youtube some people making wind generators that can put out up to 200 watts. That was at 2k rpm. Without a target wattage it would be hard to fulfill that request.
@ReadyPete Qualmers with a charge controller, should be able to slow charge from multiple smaller output devices
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.
it would work well there mate and it is on my mind too
Fabulous. I had a thought. Couldn't you have a second coil in the hub, and wire it up together with some diodes so you have 1 set of magnets but 2 coils,?
yes I think you could mate
Hi Robert. Is it possible to have the radial and axial configuration combined to get the most out of this generator? I think it’s possible to have them at 90 degrees apart from each other and wire each coil in series or parallel.
So how big would you need to build a loop and what size copper cable would you need to get a usable voltage and current so that you could charge a bank of off grid batteries?
Thanks again for another awesome video.
cheers mate
Amazing. That is awesome! I need to save for a 3d printer. That would be perfect to charge my camping trailer batteries.
awesome
Hey guys, loving your videos and thank you so much for your time making them.
Do you think the bearing can be replaced with 2 of the same magnetic poles to reduce friction, or will this upset the setup?
Yes, absolutely
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
Could you hook one part of the motor to 1 propeller and the other half to another propeller that's mounted in reverse so that the same wind effectively gives you twice the speed?
This coupled with your flat winddisk is viable ,practicle and simplicity in motion. Make a prototype and I will be buying in!
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.
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.
magnets are expensive mate - UK£3.60 in this model - wire is cheap - 35p in this model - I wouldn't rush to more magnets if it was me
@@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.
@@ThinkingandTinkering LOL You are almost ready for a 400K coin. Well done sir.
Just saw a link for your 1kW wind turbine. Is this the stator winding for that? Would this be an improvement if not? Thanks.
Dunce question. If horseshoe magnets were chained, would that work with the copper coil? Or, does the magnet have to face the copper wire? Hope this makes sense.
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. 😉
I have printed my own bearings mate - I don't use them much as they don't last
Another cool thing about this design is that the frequenzy is going to be quite high so the resistance in the wire is less of a problem.
The best videos on youtube are here.
Where did you get that big spool of copper wire? I am wondering if you gradually increase or decrease the size of the copper wire if that will make difference in output. For example in the Mighty Mite if the inner winding starts out with a bigger guage and each subsequent winding on top of the previous gets smaller.
wow cheers mate - I bought it ages ago from a uk supplier that I found on the net - I no longer remember who exactly I am afraid. I don't know what effect changing gauge would have mate - sorry
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
Looks brilliant.
However, it leaves the question of how much current it produces at the output voltage.
Also, if you put make it into a fan blade and add it to a Darwin wind catcher, it could be a great wind generator.
power is going to be around what you expect - there is no 'breaking the laws of physics' here mate
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
👍🏽👍🏽👍🏽 thanks again for taking through this. That looks like it works reel well.
Does the tape and the plastic housing between the wire and the magnetic reduce the potential of the system to generate. It seems like a design where the coil would be wrapped around the inside of the plastic would close the gap between the wires and magnetic and increase the generation.
yes - but it a 3d printed part and what you are asking is a question of tolerances
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.
yes it does and you are right square magnets would be better
Hi Robert, I'm building one of these, I've been looking for a video on how to coil the wire but can't find it(did you make one)?thanks alot, great videos, by the way.
🙆♂Brilliant work Rob! You're Awesome! ⭐⭐⭐⭐⭐
