Can you use fractions in place of the variables in the equation?

Son: "Hey dad, look what I made with 2 gears, a pen and some paper!" Technic Brick Power: "Hold my beer." Nice build!

Pretty cool but the name is a bit misleading, may be better to specify it's a mechanical display counter

What a tremendous amount of work! Thank you for sharing, I found it very helpful.

Wow great machine. Here is my humble attempt. kzfaq.info/get/bejne/h8WXp6Rl2Lm-p58.html There has been two major upgrades since this machine was made. Really appreciated your gear meshing KZfaq as well. Very helpful

I love how elegant it turned out! Was searching for gearboxes using this part, as I am making a gearbox that will need to switch to 4 different outputs, wanted to find a good mechanism for holding the cam part in place. Awesome solution, and I love how you translate the movement of a lever on top into the 4 orientations of the orange cam.

One of my favourite KZfaq videos! Thank you, i hope you are well. You inspired me to create my own mechanical automatic gearbox. I used everything i learned in your theoretical series to design my own such that it would fit in a Lego race car. It's high speed, high torque and I think about as compact as it can possibly be. Hope you enjoy! kzfaq.info/get/bejne/fZ-bmNCnttXLoJs.htmlsi=oPxCVlI8MQ__P6Cj

How to buil link vidio how to buil this gun i like pls i want i look that gun WWW2

Awesome. Well done

Genius stuff. I'll be the folks at Lego were like "I didn't know that combination worked".

Thanks for including clear build instructions. I'll go and vigorously shake my bag of Technics right away! 😂

Here I am three years later to let you know this is EXACTLY what I needed. Thank you for this comprehensive and easy to understand video. 🙂

Really well explained, mate. Ingenious design - I'm thoroughly impressed.

Bought some bits off ebay. Followed your advice and absolutely chuffed to bits with the result. This was just the fix I was looking for. Thank you so much for sharing 😀😀😀

Hvor fik du det der

Hvor fik du det

Good idea. I was thinking of making one with a barrel connector from a AC/DC wall converter- that way, it is a plug. Also, I was thinking of making another one with 3 3.7V rechargeable Lithium AA cells. But I would hate to keep taking them out to recharge. I'd have to have the charger external, which I guess is doable. Also, don't know if the motors would like the slightly higher voltage. They are 12 V motors but I think they'd last longer at 9 V.

Can i have a version with slightly smaller wheels

Why is it specifically a "Mercedes"?

WORKS PERFECTLY!🎉😊

instructions?

Hello from Canada. Does the Lego train motor incorporate the ability to maintain a constant speed over varying terrain and voltage level? Thanks in advance.

I can't believe how much I'm struggling to find an answer to this, but how can I add a stop button that resets the slider to zero. Even when I manually slide it back to the zero position the motor keeps humming. Otherwise making the slider reset to zero when you let go would be just as good for my purpose (want to prevent a vehicle from crashing when a kid drives it). Any ideas?

Simple y fantastico!! muchas gracias! estoy comenzando con powered up gracias a tu tutorial!!

awesome! I can envision a smaller version that goes without the clutch and the rotary catch. All that's needed is a swing arm with a fixed cog, to block one of the paths

great explanation!

awesome! but what's clicking?

so in the set up at 7:25 you should switch places between the black cogs on the left and the light gray cogs on the right, making the main input of the differential the slower one, and repeat the pulling experiment

Please, do you have similar video with the new app? I am trying to add a simple widget and it.s not working. Everything looks different. Thanks!

Hi, is there any c or cpp api? Would love to have this using code

This is fantastic! I've built a couple of Spirograph designs off Rebrickable and both work well but don't reproduce the same type of patterns as the original gear version you showed. I think you've done a great job recreating the same style as the original. I would love to see a more in depth look at the mechanisms involved in your design! It looks delightfully complex. One idea I have to help with the little hiccup when the pen drops in would be to have it move vertically to engage with the paper, maybe with a linear actuator, not sure how feasible this is though. Anyway great job!

hi i am from india i wanna really make this car so how can i identify the lego bricks names

Hey, what's the software you used to render?

That’s such a smart mechanism with those off center turntables, amazing build as always

Здравствуйте, а можно 3d модель, этого устройства?

really cool good job!

If you made your pushing vehicle rear wheel drive, or all wheel drive, it would have pushed those two other vehicles more effectively.

Excelente tutorial! yo abro la aplicación y me aparece un diagrama diferente, puede ser que este haya sido actualizado y no coincide con el que hay ahora en diciembre 2023? saludos!

This is one of very few powered up tutorials, but all it seems to talk about is measuring power. Useful, but there's so much variety in powered up.

This is wonderful!!! I've created quite a few two speed gearboxes, but they always require a seperate motor to shift the gears!!! This is something truly unique, and innovative!!! And also it's amazing to see how powerful this gearbox is! Had a bit of difficulty trying to create a strong enough gearbox for a project (it had to handle the force of 6 Lego EV3 Large Motors!) and finnaly managed to do it, but I am totally using this instead because no shifter motor required - now I can use 7 EV3 motors! Thank you very much for pushing the boundaries of what's possible for legos, in your own way - truly appreciate it! unfortunately I just realised I can't - Sadly, this innovative design has one flaw, can't go in reverse!!!! Output is always in one direction ): But still an awesome build!

Well done! What are final speed ratios in 1st and 2nd gear?

Any tricks to keep the axles from pulling/falling out of the internal differential gears? I'm using new parts and the enclosed diff. shell with a red main gear.

You are insane😁 Well done!

Could you do a version of this for aligning liftarms with each other at angles? For example the well-known 4-5 triangle that allows a 6-long liftarm to snap onto the grid at an angle. I was wondering if there was a way to figure out larger combos.

Uff, this is genius! 👍👍

Pleas build instructions

How do you control more than one hub?

Love that you've experimentally tested low torque high rpm Vs high torque low rpm versions!

This is incredible, thank you! I've been building an auto gearbox and have been having a really hard time calibrating it when it's in the car. Knowing this will help me a lot, thank you!
