Motorizing a Music Box using a 3D Printer (Ultimaker 2+, Fusion 360)

- I'm working on an alarm clock that uses a hand crank music box as its chime. In this video I 3D print a frame and wheels to drive the music box with a small DC gear motor and rubber band. I also encode the hand crank rotation using the hand crank as a switch.

3D printers help turn ideas into reality. This was a good video to watch.
I feel like I was left on a cliff hanger... I would like to see more videos like these. I know its been 4 years but it would be great if you would finish it :)
Hey Miguel! Thanks for the nice comment. There will be no finish to this video hah. I ended up making my nerf alarm clock and didn’t use the music box. Stick around for videos on synthesizers though
this is a million times better than having my dog scratching my forehead
so cute!
This was a great video.
So I was thinking of making a digital music box and a spinning element powered by the DC motor. The reason why I think it might not be a great idea is the motors noise. If the point of a box is music, whining of the motor defeats the purpose. Probably a specific DC motor with extremely low noise could do it, which is tough to find.
Great Video, I like how you show all of the steps. Keep up this with new format!
Thanks! I also decided to make my projects a bit smaller, I think I can do a video like this every 2 weeks if everything goes right.
+Normal Universe That would be awesome! I really like how you do it legit by making sketches and then taking it to CAD.
Very accurate wirings!Nice to look at!:)
Beautiful execution. I liked and subscribed
Dor Fire aww yaes
Nice idea!
Really snazzy 3D printed parts, then all that hot glue goop everywhere during construction. Had a bit of an eye twitch watching that.
I like using hot glue because it sticks well but I can take it off with IPA if I need to. I think things look extra gloopy because the parts are pretty small and I'm zoomed in on the camera.
Very cool, very informative. I wish I was this good with design and 3d printing :p.
Are there any resources you would recommend to get better at design?
Thanks!
One suggestion I have to get better at design is to take apart your things once they break. As you crack it open try to predict how things will look (e.g. Where the screws will be, what a part might be shaped like) and then compare the reality to your predictions. There's a channel called EEVBlog that has a lot of good teardowns like this.
If the CAD software is hampering your ability to think creatively because it's hard to use, then sketch your ideas on paper first. Usually I sketch mechanical drawings or cross sections before modeling something. I recommend Fusion 360 for CAD it's free, powerful, and has a good UI.
Just ideas, whatever works for you. Have fun!
Hey nice job, have you posted the 3d files anywhere?
Could you please advise the details including sizes for the 3D printed parts
This is great. Can you share the 3D designs. I have a lot of toys that can be repaired using this design.
Hey I'm glad you liked this, Unfortunately I don't have the models anymore.
Um its not done though right?
I mean you have not set up the system that actually uses the rotation counting
Ya it's still a work in progress. I'll be doing the electronics for the clock and controlling the music box together.
NOICE!!!
to be fair I don't see the point of using a sensor to detect when the melody ends. If I were to build this, I would just count how many seconds it takes for song to end and use that as a reference, since the speed of the motor is constant and it doesn't seem that it will be skipping steps.
D4no00 if you have a stepper motor you might be able to get away with an “open loop” solution like this, because stepper motors move in discrete steps. However with a DC motor you need to close the loop with a sensor. You can’t guarantee that it will always turn at the same speed. Power supply fluctuations, dust in the axle, and other disturbances will always mess you up. Also how do you decide what amount of time to run your open loop motor? If your timing is slightly off you will accrue error every time you run the alarm.
is there any way you could make a video on fpg colorizers?
Sorry I don’t know what fpg colorizers are :(
@@TheNormalUniverse my bad I think I wrote it incorrectly. They're basically devices that aid in glitching video / audio. Circuit bending and the likes. You can make very simple glitches using two video inputs, a potentiometer and a single video output. Where the potentiometer changes the opacity of either input and creates an overlapping glitch effect. A colorizer I believe changes the channels of the colors (their frequency).
This is very great! Just a little question, what model dc motor (volt) is it and how fast does it go?
DarkSpriteGirl thanks! Not sure, I took it from a power screwdriver. The driver used 2 AAA batteries to power the motor, so about 3V. I used about 3 as well.
Thanx you for sharing your information, now I'll know which one I need ^^ With this, I think I can make my project happen, and that's because of your video =p
Would I be able to hire you to make one like that for me as well...without the cutoff?
Can you provide your 3d printed designs please?
Hey can you make a winding up phonecharger?
The motor is a little loud...
It's for that rustic (read: shitty) appeal
Does anyone know a music box on batteries?
what's the specs on the DC gear motor? I am unable to find one on ebay that resembles your one
Christopher Nhan Le sorry I took it out of a small screwdriver, so I don’t know exactly where to buy. It looked a lot like this one: www.sparkfun.com/products/12285
@@TheNormalUniverse thanks. Don't suppose you do orders? I live rural Australia so won't be able to locate a 3D printer or someone of those skills such as yours. But essentially want to replicate your set-up but for a 30 note DIY music box hand crank.
I know there are motorised versions of it but for some reason the motorised ones are VERY slow. HenceI prefer to get a hand crank and just attach a motor with your gears to it.
Christopher Nhan Le thanks for checking. Sorry I don’t do orders, I don’t have enough time to make this good enough to sell.
@@TheNormalUniverse thanks for the reply.
Final question, don't suppose you can guide me in the right direction where I can find a plastic gear that you used to hold the handle of the music box?
The ones at 1:51 and 1:43
@@fearlessnhan hmm I don't know an easy answer. I think a good thing to do is always be hoarding leftover products that people don't want anymore, and take them apart for scraps. Over time you'll build a collection of widgets you can use in projects.
what was the RPM for the rotary motor?
Christopher Nhan Le sorry don’t recall. You can figure it out in the video footage though
