Your video inspired me to create a wind up mechanism in 3D print, with a plastic spring. Limiting the speed of the release of the energy is a real challenge. RUclips has plenty of resources on speed governors, but I couldn't find another example of the rocker speed governor shown here. At first I thought the teeth were supposed to be shaped like regular gear teeth, but this didn't give a good result. Then I tried to build an escapement wheel with triangular teeth and that worked fine. The model now releases its energy over 8 seconds.
Dear Mr Ludic: This was an excellent video! It is good that you do not only discuss electronics topics, but mechanical topics as well. I would like to make a suggestion: Can you do a video discussing how "exhaust pipe smoke" is generated in toy cars and toy trucks made in the 1960s and 1970s?
So I actually kinda got obsessed with wind up music boxes over the Summer. The mechanism in music boxes that limits the uncoiling of the drive-spring is actually pretty interesting, and would make a wonderful mechanism for a clock-work generator. The mechanism relies entirely on air pressure to limit the mechanism, and it's not hard to add magnets to the spinner. Anyway... that's kind of the idea. Most the designs I've come up with lend themselves to AC, but I'm going to start working on a homopolar version. Especially since high capacitance capacitors are relatively cheap to get ahold of, and homopolar generators require less mechanisms for rectification.
Winding up a spring by holding the center between thumb and indexfinger and pulling on the end with your other hand is the perfect way to get 6 perfectly parralel cuts on your thumb that are nigh impossible to stitch up.. Yes, I was a stupid kid.
An excellent explanation and breakdown of the internal mechanism and energy transfer in wind up toys. I bought a secondhand toy tractor book for my child and the toy does not work. I could buy a replacement but that would be the easy way. I will use this video to try to fix it. Thank you so much! Subbed for more content.
In the case of the music box does the governor also work to control the speed so that when the spring is very tight the play speed is the same as when the spring is mid-tight then barely tight?
Question, i've been wanting to fix the wind up motors on my Zoids one of the issues i found is that on some of the bipedal ones, the wind up motor works fine while i'm holding the model in the air but when i place it down on a surface the motor has no strenght to move the legs, any idea how to fix this?
I don't know if you'll read this, but I want to know can we use this mechanism to generate electricity ? My hypothesis is it'd allowed much lower kinetic energy we spend to generate more electricity than we would generally use in kinetic generator.

Can i see your example
I would love to see more videos like this where you breakdown the mechanical functions of toys

omg thanks! now i finally understand how this works. i am fascinated by clockwork devices.
This was great and exactly what I was looking for.
Thanks for making this video!
Exactly what I was looking for in an explanation video, thank you! 😊

Thanks Sir for taking all the efforts to explain it to us
Thank you for clear explanation!

I’m trying to create a working wind up Hunter from YuGiOh. This helps alot
So interesting! Really informative video
This was so helpful!
Amazing video. Thank you so much! Subscribed!

Great video!
Very well explained up to but not including the governor mechanism. How is the energy of the spring transferred to the governor?
"It just works"
Nice.
lol
lol
🤣
Bro- 😭😭😭
Excellent video! You are a great teacher. Thank you!
5:16: That little white/silver ratchet looks like a 45rpm adapter that was used to play 45rpm records on a turntable that only has a 33rpm spindle.

6.22
A bigger model 1000 times big
Operated by hydraulic winding key 🔑
So we use our weight to operate the bigger model for making electricity ?
Large model became beneficial for big pollution free factories
Awesome! Thanks!
how do you reduce the unwinding of the coil spring?
Great explanation, thank you!
Glad you like it!
I'm trying to figure out how to put a music box in a doll.
why sometimes it doesn t turn anymore? what should we do or replace?
This is another example of an escapement. So interesting.
Does anyone know how to DIY create or buy the white plastic piece at 7:21? Thanks!
You could probably 3D print it, your local library might have a 3D printer you can use
Where could I buy these small wind up mechanisms?
5.40
If we make a 10 times bigger model of this
How much energy in joules required for making its working ???
If it is bigger u need more power to turn it which is more harder to do
Could you scale it up to say 3ft x 3ft to make a wind up battery charger or something?

Spring leaflet
What is energy constant of spring in joules
If we use 100x strong spring how much power we require to winding it up
If we winding up the strong spring with 50 ton hydraulic jack then how much stronger spring required to give power for one hour at least
How much energy it store ?
If we made a bigger model for 60 kg force
How many times bigger it is ?
Look at spring balancers.
I'm finding the best way to learn about mechanical engineering is through toys.
What its energy in joules
Spring energy restore how many joules
How much joules of energy it store in toys torsion spring
This dog required how many joules of energy ??
What is🚕 energy⚡ store by this setu??
Thank you, very clear. :)
👍👍👍
How we can make big engin like this ??
Cool
Anyone who made big model of it so we attached it with dynamo and charged our cellphone with our power
u forgot clocks too
0.27
Red key winding up toy
If we make a 10x strong model then how much power it gives
Please do the math so whole globe get rid of energy crisis ?

Are you Italian?
Very good Video, like always. But please clean your Hands if You make This type of camera closeups (zoom)
👍👍👍👍👍
