Hello music box maniacs! I'd like to share with you the video I made this year to wish you Merry Christmas. I like music boxes, and I like machines in general, so I mixed both worlds to create an automatic punching machine. It's not finished yet, but it can punch a song with 619 notes in 3m30sec.
I am very impressed! Yours sincerely Christoph Enzinger
Merry Christmas everyone!
I know this post is quite old, but this little machine is _so_ impressive that I had to leave a comment. Congratulations on your achievement. Do you have any information on the web with details for how it is made?
I also need to know more! How does one create such a machine?
I'm glad you find my little machine impressive :)
I first started to think about building an automatic puncher machine when Martin Molin (Wintergatan) published a tutorial on how to create perforated paper for music boxes:
Some people around the word reacted quickly and created an application to convert MIDI files into a format that laser cutters and cutting plotters can read. This solution has a drawback: you must join several pieces of paper in order to have a complete song.
So, I started to think on building a small machine that could perforate paper in "real time" (1 minute of song = 1 minute punching). Some people built automatic punching machines earlier than me:
But I pretended to build a faster and more robust machine. My first attempt was this machine:
It was based on an aluminium block in which I machined 20 pneumatic cylinders with 20 perforators. I didn't go further on that solution because it was a very expensive approach: machined parts, electro valves, need for compressed air, 20 independent perforators... And that machine was only for 20 note music boxes. I think I could get "real time" paper perforation with that machine because of parallel punching... but I didn't continue that way. For other machines (15, 30, 33 notes) was necessary to create custom punching blocks.
I posted some photos of the building process for this machine here:
I started to think on designing a new machine, suitable for all programmable music boxes (15, 20, 30, 33 notes). I bough a 3D printer and learned to design in 3D. My idea was to avoid machined parts (that are expensive) without sacrificing precision and robustness. So new machine is basically made of 3D printed parts, laser cut parts, standard elements of mold making (the parts that perforate the paper). The electronics is based on a PCB for 3D printers with Marlin firmware.
Currently I haven’t posted anything about this machine on internet, but I can continue here with more details if you want.
admin dont give a shit tbh you wont see any meaningful staff here they have PHISHING LINKS that serve to hack you and log your ip via GRABIFY HACKING all over this site. I would NOT post or click any links here. You have been warned.
