The Huygens Chain drive allows us to play continuos music!
I´m not posting a feedback link this week, will only post when i have specific questions for the feedback, currently I´m still digesting the ins and outs of a weight driven system.
Good luck with everything you are doing 🙂

This is interesting, but it does concern me that you are taking out too much of the human expression from the music in pursuit of perfection… I am a huge fan of music that varies tempo to create emotion, and probably my favorite part of the original marble machine video is when you slowly crank the thing up to speed
You might also look into the practicality of things like springs they make clocks extremely precise but I don't know how well they scale
My 5 cents. I really enjoyed the music played by the very first machine. It was AMAZING! How tight it was? Who cares! It was AMAZING! I don't think your typical audience will be 50% musicians and 50% computers calculating standard deviation on the fly. More likely it will be 99.9% of us average Joes and 0.1% of music perfectionists who can't listen to something if even 1 beat is off by a millisecond.
One thing to consider is that when using automatic devices on the machine, the less skill the player has to use for playing the machine. Therefore, the personality of the music is removed.
If you're going to make the MM3 a big clock, you could consider designing for clock aesthetics. Bonus points if you happen to implement a large pendulum instead of a flywheel, which could be the centerpiece of the entire thing. Although if there's no pendulum, then a massive gear housing, which is probably required anyway, spinning around in the center behind a transparent glass or plastic plate, would certainly be a very pretty clock aesthetic as well. It would also be a sweet callback to the planetary wheels of the MMX.
I like the positivity, keep it up.
i like it. I can imaging the weight being visable to both you and the audience while cranking the machine. You can make it a part of the stage, maybe even playing something manually while the weight slowly drops on it's own and then turn around and start cranking before the weight hits the floor. If we're talking about showmanship, it definately has merit. (and of course it's mechanically viable as well)
I think the thing I’ve come to appreciate most about this channel over the years is the evolution of what makes this struggle so inspiring. Regardless of my personal opinions about design/engineering/approach/mmx/ and so on, I have immense gratitude and respect for the fact that you’re continuing to carry on in spite of everything. Incredible.
Pleased correct me If i am wrong, but the more mass your system uses the Higher the interia is and the tighter the music gets.
So to compare mechanical solutions you would have to all moving parts the same Wight.
This machine will never fly. I thought it was supposed to fly at one point or another in the past 5 or 6 yrs. I could be mistaken. If the machine were a flying machine it could transport Molin to destinations on the worldly tour. That would be so cool.
It's funny to me how this is basically building up a mechanical analog of a linear electrical power supply, you have an alternating power source coming in (your foot peddle), some form of rectification (converting the peddling to turning of the shaft), a capacitor (in the form of the weight), an inductor (in the form of the flywheel), and now a linear regulator dumping excess energy using resistance (in the form of a governor).
i just wanted a new album 😢
Next week he’ll discover that combining the Hyugen Drive with two metal shafts spaced at equal intervals allows him to tell time better 😂
Try a clock winding differential. Please!
That’s pretty cool 🐰🍷
I love how the channel has almost come full circle – the name Wintergatan of course inspired by astronomy, and now using a device originally designed for astronomy for the centerpiece of the channel!
I love how Martin is finally, finally beginning to rely on previous inventions for this. The growth from musician to engineer over the years has been quite the marvelous journey!
or just scale up a gramophone mechanism + friction mechanism on the main disc 😀
I wonder how the speed of this system can be increased or decreased to meet specific tempos… it's going to make it so smooth for recording to, but is it going to need swappable gears or a gear box? How can it get the full tempo range? Can adding more or less weight slow and speed up the system?
Kind of steampunk to make such music with clockwork type mechanisms
Martin really needs to define what "tight music" is. He mentions in this video that he specifically had stuff he could not do on the older machines that he wanted to. I guess he wants it to become a true musical instrument that is as precise as the user? The fact that most of the comments and things I read here think he is being "too perfect" screams for the need of at least showing us what is wanted and what is allowed failure.
The governor and flywheel idea is a good one, and an old one. They've been used for centuries. Old farm equipment relied on governors to keep equipment running at a constant even speed. Threshing machines for grain processing were powered by steam engines, whos power output could vary depending on the available steam pressure in the boiler. You could automate the recharge of the weight using some limit switches and an electric motor. When the weight reaches the bottom, it could turn on a motor attached to your ratchet which lifts the weight to another switch that turns the motor off.
You’re building a clock….
Maybe I'm missing something, but haven't these problems been solved by manufacturers of mechanical music machines before? Clockwork music boxes? Nickelodeon player pianos? Band organs? Ok cool, you want to reinvent the wheel…but there is a whole world of mechanical music devices that existed well before this project was conceived. Heck, player pianos got tight enough to faithfully recreate a player's performance. So, maybe Martin might want to do a lot more "R" and a little less "D" and maybe he might get a heck of a lot closer to his goal a heck of a lot quicker…
Keep working 💪 I hope to see the world tour
So in addition to the other limits and governors, you want a clutch mechanism on the ratchet crank so that you can't go overspeed and throw the weight drive off.
Logistically, the weight will be difficult to manipulate when in transport or setup/teardown.
What if instead of a weight, you would store your potential energy in a spring system or a pneumatic cylinder/accumulator compressing the gas?
