Very encouraging the watch you go from idea and concept to finished proof-of-concept, and fully working prototype. Thank you so kindly for taking us on these many journeys, of exploration and discovery. A plethora of positive spiritual energy in a world that has at times forgotten itself.
I finished building one of these myself last week from your older STL file. ( I designed a longer end cap ) and was very happy with how it turned out. I used 3 coils with 200 turns each of 0.2 mm O.D. wire, about 90 ohms each. Wired it in parallel with a full wave rectifier on each coil. I spun it with a drill and it dimly lit a 12v incandescent auto bulb load and produced about 8 volts at 400 milliamps. So it was putting out about 3.2 watts. :)
Same here although i wish he'd use parametric desing(the downside of using tinkercad i guess) so the files were easier to modify to fit our custom needs. I want to make a smaller version of the fold up turbine and simply scalling doesnt do it, but thats not easy to do as im finding with my own designs so i dont blame them. Maybe they'll find some benefit in it for themselves as well and start add some to their designs. I see the'yre reusing the same thigns over and over and if im not mistaken you have to make them from scratch in tinkercad which must not be a problem if youre good at it and it seems like they are, so whatever works. But if anything needed parametric desing, all these shapes and sizes of gears would be it.
@@mikejones-vd3fg The best solution is to be able to use a CAD program well enough to design your own models from scratch. It is a little painful at first to get to that level but if you stick with it you will definitely get to that level. There is so much help available from the internet and TH-cam to help you get there. Just Google any single problem you are having and you will find the answer to that hurdle. Step by step you will learn it.
This is great! Some of your older videos achieved the weak milestone of "lighting a led" .... would love to see some of them revisited with a proper test Cheers mate
Hi Robert! i have made "Penny Sand Batteries"! I got an LED to light up from it. and I have been experimenting with charging little capacitors with them to see the potential in the concept. Super awesome. I'm trying to find ways that people can make cool things like this with the stuff they find around the house. Thank you for sharing your ideas! I'm trying to do get those ideas out there. :)
Brilliant very powerful little bit of kit made for next to nothing literally thanks Robert tell you the truth I'm quite impressed with it and I've have bundles of thoughts around the gear ratio system i mean there's so many possibilities it's a must Good Job 👍
"You can bet your bottom dollar." Odd choice for a man from the UK, but it "just goes to show you" that great ideas are universal, and not just the province of the rich. Kind of your theme, I suppose.
Just a few wee notes from myself. It's better to use the series to get more volts as this will be less amps = less loss on the wiring and thiner wires = cheaper to build the whole system. Just keep in mind you need a MPPT controller, the one I'm building now to stabilize the charging power to the batteries and load. Without it, with a regular controller, you won't have: 1. Charging phases which are 3 and some for a quick charge and other to sustain. Without it you're killing the battery quicker. 2. If no controller, no protection, can damage batteries and other equipment. 3. The charging itself if no MPPT controller = higher losses, but synchronous controller like MPPT max out the possible charge. The one I'm building now goes up to 80V on the input and max 30A, but firmware is limited to 1kW. It's a great project and open source with an app for your smartphone. I'll make a video about the build soon on this/my TH-cam channel.
Would be kind of cool to build rare-earth-free motors with iron nitride or something, they are heavily researched at the moment. Or even just permanent magnet free motors like MAHLE's.
Hay Robert, just became a member a few days ago. Really enjoy the projects and has had me collecting stuff as of late and pulling parts out. Do any of the earlier videos break down some of the basics on electricity? Trying to wrap my mind around the components I’m pulling out and what Is useful.
Ive built myself a similar generator. I would like to work out the power output of it but not sure how to do it. I understand I need to put the generator under load and that volts x amps = power. I can measure volts easily but struggle to measure amps. Can I do it without a precision calibrated load like you have? I have a couple of multimeters to measure volts and amps at the same time. What sort of set up can I do with multimeters and LEDS or resistors as a load? I have built a rectifier for it too
I would love to see everything working in conjunction. The gravity battery working with the pendulum and flywheel using your gearing system and generator. What is possible? I love the content and you're a great teacher.
@@ThinkingandTinkering I'm sure other people would find it interesting. It would be a good throwback to your old capacitor videos where you could talk about smoothing output and such.
in making the ring gear for the planetary gear system. I subtract away a inside gear from a larger circular shape. I assume this is how you do it in Tinkercad. I am wondering how you add backlash to a ring gear doing it this way.
@@ThinkingandTinkering So you increase pitch circle diameter or module a bit. I wonder if the programs like Tinkercad or Onshape, do that same thing, when you add backlash to a gear.
super! how to find your old videos on youtube? it's a shame that your valuable work is not archived.... is it youtube removing them or is it a choice on your part? thank for your work
it is hard to get to them with them not being archived properly - i am in the process of putting relevant videos together in omnibus editions in the omnibus playlist - that should make them more accessible
I am having difficulty wrapping the coils. I have two on now and although they each read about 60 oh one seems to be producing more than the other . I The weaker coil is the outermost one and is farther from the magnets. Not sure how I am going to stuff a third coil on. I modified the stator to have thicker vanes. making it sturdier and expanded things a bit to fit inside a 4 inch green PVC pipe. The ends are square allowing 4 long threaded rods to hold the top and bottom together. Happy with the design mods for the most part but I can't see m to get more than 12 volts when I wrap a string around the shaft and give it a good pull Series about 12.8v and parallel about 7 V. Am I doing something wrong? should I bother to pit on a third coil. I did make the jig but had to expand it. these were AC readings
oh - i managed to line my up side by side - you shouldn't feel much in the way of torque when you pull - what that means is it is going no where near fast enough - so you are going to have to gear it as you are not spinning it fast enough mate - tomorrows vid should make this clearer
Hey, Have you ever heard about solid-state electronic generator? Bard, Google's AI told me it has the potencial to be a clean energy producing method. It would be interesting to check that!
Not knowing what you want to do and remain flexable, It may be nice to simply terminate three coils with 6 terminals. That gives you the flexibility to try different ways to recitify three phases. If you seperately rectify the output of each of three phases, you may as well as also add three capacitors, one across the output of each bridge rectifyer. This way, unloaded, you'll get closer to 3× the peek voltage of each coil, rather than the sum of three different phases. The down side of three sets of bridge rectifyers with output in serries is a voltage drop in the amount of six diodes.
How much could graphene strengthen a carbon fiber hydrogen tank? With just compressed hydrogen? What about those tanks that have both compression and liquid hydrogen?
Instead of spinning by hand, it might be easyer to wind a string or rope on pully. One can pull it by hand, or for more consistant results for testing, one might add a known weight and let gravity pull. 😊
it's a funny thing when i don't use it i get exactly the opposite complaint lol - just goes to show - no pleasing everyone - in fact i have also been praised for zooming in - lol - sorry mate but that did tickle my funny bone
Why push the volts? anything above 55v outside you start seriously breaching IEE regulations (RCDs etc) surely you're safer limiting the volts at 13 m/s (likely top power output) ? Va x Ia = power .... there's a reason why site transformers are limited to 110v (55v centre tapped)🤔48v peak output maybe the best option but 24v or 12v shouldn't be discounted depending on location/system
@@IC86688 tru , but is it worth the risk ? 55v is the limit for a reason... the cost between a cable size or 2 is negligible unless you're talking long distances (volt drop)
@@sailaway8244 there is a limit to how fast you can turn something - you can't make your arm turn faster it is just physically impossible - but you can use gears to do it until you reach a torque you can't shift - that way you are getting the most efficient output from your machine. You can just turn it slower in which case the volts will drop but you are using your machine in a very very inefficient way - almost making it not worth doing. But then everything is safe if you just don't do it.
@@ThinkingandTinkering agreed, just highlighting the issues with breaking the 55v extra low voltage barrier that you'd break gearing up with 2 or 3 sets of gears.... maybe a form of speed switch maybe a future project switching coil configurations with wind speed something like a star-delta starter would do using trigger voltages on a relay or two.
You are making several mistakes! You measure the efficiency of the entire system, generator, rectifier, thin cables and a non-linear LED! The worst is that you connect 3 voltages that are out of phase with each other. Start over, connect only one resistor per phase, measure voltage and current, multiply for power...
Very encouraging the watch you go from idea and concept to finished proof-of-concept, and fully working prototype.
