can you do Less complex electronics ?.

This is awesome but technically this isn't a CVT as the ratchet doesn't have infinite teeth

What kind of bb's are those? ⭐🙂👍

a decent quality servo motor will be at the same price, motor + drive, and industrial drives have many pro features

That link shows a gear ratio of 1379 to 1 which seems impossible, if this is possible, why don't they put those in a winch? Every wench I have seen starts off with a 90 or 95 to 1 gear ratio and has three sets of planetary gears.

wel i gona use this for my ebike XD

I want planetary with 2 output shaft with ratio 3:1. Can you help with the design .dxf format please.

Dude this makes me so excited to get into this stuff thanks for the content!!

...não pude ver a ré?!?!?! ...I couldn't saw the rear.

Outdated ratcheting pawls are replaced by peanut shaped cams. In either case they overun, accomplishing 1/2 of your objective.

I’d appreciate it if you at the beginning of the video mention that your content is paid content and without payment the video doesn’t make sense

Hello, i am making a small scale train for an engineering project and i wanted to install a small cvt on my train. Your design works perfectly but i need to scale it down a bit. Would it still work if I scaled down the entire thing?

Been so long I have noticed. Here a proposal: Pick a steerling engine and make it air powered. Also, you can make the parts out of a thougher material;

I found a use for it! I trying to make a baby mobile powered by a DC brushed motor- but obviously I'd need it to spin a thousand times slower- so hopefully it'll do the trick lol

I saw a lot prototypes of gearbox and this one is my favorite. No clutch, variable gear ratio. If is possible to balance mechanism to eliminate vibrations then it could be used in low rpm diesel engines

Anyway you can do high ratio with a worm gear? I need to transfer motor to an axel.

The sad thing is GLASS fiber nylon would be a far better choice for this application than carbon fiber…

what would be the purpose of this one ? i mean where you could use it ? does it work upside down as well ? the idea i had using CVT was to have something like harmony turbine to spin on wind and the cvt to offer a constant rpm to the generator and produce steady power, which means that the CVT should be able to take low RPM and transform them into high RPM and middle to high torque. Could that work ? thanks

Nice info, thanks :)

Well this is getting stuck to a gantry and handed a camera in my studio...

I like how it matches your shirt 😂

When your new videos hit their feed. They're reminded that they're subbed to you and that they no longer care about engineering so they unsub.

I dont know why they dont try different designs that was not possible to try using wood

You're doing great, just please please please don't ask chatgpt for engineering advice. LLMs are useless for this sort of thing, they're just stringing together related words. I gurantee you know better than it does.

The loss of subs could be caused by people forgetting about you because of the hiatus and then getting your first new video in their sub box. That one was kinda rough quality wise. Keep uploading and it'll sort itself out

I would recommend against having the second magnet disc. In the best case, it won't do anything, and in the worst case it'll add a spatial pulse to your data artificially limiting your potential resolution.

Regarding your subscriber count... Try to refrain from anthropomorphizing the algorithm.

Nice job, love the data driven experiments. Thanks.

Did you think about describing the problem using a differential equation? I just remember, it was annoying, but on the other hand, I would be interested how much it aligns to your experiments. Maybe, I should pay more attention in the videos of the Hyperspace Pirate. And it might be only me to be interested in that, because actually calculating that is on my todo list since it was a question in an exam of mine more than 13 years ago.

9:51 This sounds like one of the problems tackled by steam trains. While there will be differences between hot 200psi steam that can condense and 40psi compressed air, I can give some pointers as a non-expert For the max power you want to admit air until the end of stroke (a long cut-off) For the max efficiency you want to quickly admit just enough air to expand to exhaust pressure (a short cut-off) Steam engines varied this on the fly, starting with max power and trimming down the cut-off to use as little steam as possible Another thing steam would do is let air in just before the start of stroke (lead) to cushion the stop and decelerate the piston head. This I don't know if this helps or hurts efficiency but it did help reduce wear wear and tear, especially at high speed. A key difference in locomotives is they needed the piston exhaust pressure to do other work, in this case you can use all the pressure Again, I'm not an expert, I don't know much about the effects of temperature ad temperature change, but I would trial: - Adding some way to change cut-off on the fly - A small lead on air admission - Find how little cut-off the engine can run with, Ideally independent of pressure Looking forward to the next update! 5:43 About subscribers, you might have people who had forgotten the channel and once they were reminded by your upload they chose to unsubscribe. I for one am glad I was subscribed, it was a great surprise when you first uploaded again

That is only the second video since you came back, isn't it? I always hoped for new videos. Did you just not feel like making videos in the meantime? P.S.: I tried to build homepages and edit videos and I think I have already done interesting projects. But I never managed to do all at once. There was only time for the project or for filming it or for working on a homepage. So I understand, that tasks like finishing university while living in a small flat makes finishing a youtube video about a project very, very hard.

Welcome back!!! I'm so happy to see you back!

There are several potential reasons for losing subs and it's likely a combination of all of them to some extent. People's interests can change so it may take some time before you start finding more new people than losing old ones who are being delivered content they no longer like. I could be wrong but I remember your last few videos having better production than this one (specifically better audio and editing will go a long way), quality over quantity seems to be working for a lot of the youtubers I watch these days. Related to the last, the landscape has changed. There are far more good youtubers making videos in this space that I've discovered within the last 4 years, competition is likely affecting people's decision to stay subbed or not. I'd recommend getting a better microphone and invest in some noise isolation (or just invest more in your set/workspace in general), hiring an editor (if it all feasible), getting a camera on a different angle and/or adding an intro/outro so we aren't just looking at the same table the entire video and taking more time between videos to polish them more and show us more of a complete project than just a snippet. Just my 2 cents but those are the kind of changes that seem to get a lot of mileage for other youtubers these days.

4 years is a long time, maybe a lot of people are just not watching the same things they were 4 years ago. I however will always be watching maker content and am glad your back.

😊Glad to see you are back

We are so back!

He's back!

Great to have you back! I don't think people are mad at you for not uploading.. I think people are like "what's this thing I don't recognize in my video feed".. a few years is a long time for the yougins..

Like the old Top Gear, ambitious but rubbish! Good show ol boy!

I want to subscribe just to unsubscribe now

Did you zero the load cell with that arm sitting on it so it doesn’t portray that weight as part of the torque measurement

5° past tdc

I fully expect that the magnets behind the aluminum disc will be mostly neutral as when the magnets are oriented the same way as the spinning ones it'll pull flux through the disc but when they are opposing it'll push the flux out of the disc. I think all you've really accomplished is creating cogging.

Thanks for the edit, my old ears don't edit out voice from music that well anymore. Its great to see another video from you, happy christmas etc.

I don’t know why I’m subscribed to you. You must have made something cool in the past I don’t remembered.

This is even better the second time it was uploaded.

You are back!🎉
