Loved the project. Based off the title I thought this be electric in the same way an electric guitar is.

Add a ease in and ease out to servo motion it will make it more quiet

my guy 🇩🇪

Can someone plz plz let me know the software for parts design

The base I'm on had these sun tracking panels. They doubled as shaded parking and was a grand idea. Unfortunately the motors siezed up pretty fast due to the salt air and the lack of maintenance with cleaning the panels. It took 4 years just being stupidly expensive car covers for them to finally remove them. I work on maintaining the electrical infrastructure on the naval bases and solar is definetly desirable but the lack of training to maintain and work on them is the bottleneck in my opinion. Good work on this project and I hope to see a similar version while I'm on base one day!

That was so fkn cool xD I was nerding out over here!

This is amazing. Could you share the stl files?

If you do end up going with a slip ring again it is fairly easy to manufacture one, especially since you have a 3D printer. All you need is rings of metal to solder to your wires (The size just has to be close to the size of your wire.) Then you attach small metal wipes (Thin metal strips or even ends of wire that are flattened and are solid or have been tinned) The wipes work the best when they are rounded so they don't try to go anywhere when you go the other direction. Add a spring to make sure the wipes have good contact with the rings. And attach both sides to independent casings with a center attachment point. metal or plastic rods work for this. Just make sure that the stress of turning gets put on the slip ring and not the wires coming out. This way you can have a slip ring with as many or few connections as you need and size is dictated by how many wires and their sizes. Last bit, if you add multiple wipes per ring that are equally spaced it will reduce the resistance variation over the rotation.

Love the cloverleaf design Awesome video & project, keep it up!

Source Code and CAD Please @axelmadelt

I want to buy this project.

What a great project to start tackling the subject and learn a bunch of engineering fields - mechanics, electronics, programming

One pick per note would eliminate the gear train noise and lower complexity. Also, it provides a greater range as two notes can be plucked at once.

incredible video and process. so inspiring! thank you

Can you provide links to the circuit/PCB and 3d-printed parts? Thanks!

is this mecatronics ?

is this mecatronics ?

Trying not to see the german *Hindu* symbol.

You are a mechanical and technical genius!

can totally add a midi interpreter in software and push it from a PC running Hairless MIDI to the Arduino Nano's serial port. you'd have to minimize the midi files for the limited range and speed. Hairless is a MIDI-Serial bridge that will show up in your DAW and you can use it like any other "normal" MIDI output.

Can you give information for the tools what you use thank you

Man im just done . I am 18 and dont know how to learn this things . I love making stuff i have ideas but dont know where to start

Germans build the most crazy things 😂👍

Impressive!

I think the servo noise might actually be an upside if it's tuned more, many instruments have some sort of noise artefact from how they function and i find that it can be quite enjoyable. Key harps are a great example of it, they can have a very obvious clacking sound from the keys being pressed.

Job well done!!!

Omg why did you not make one of the songs Haggstrom!!!

This was a great build. super job.

Lovely video! Design suggestions 1 - use a horn on the hole in the resonator box. If the box is elliptical, you could have the Kalimba at one focus and the hole for the horn at the other. It's possible to tune the dimensions of the box to the root note of the Kalimba. 2 - isolate the box holding the resonator from the box holding the servos. Rubber washers between them and rubber feet for each box. 3 - cover the servos as much as possible - leave a gap into the box they're mounted on, and print a simple maze inside, or line it with the foam to make a baffle I have a programming suggestion to help integrate the servo noise. If there is enough time, ie. the plucker arrives but would have to wait more than one beat to play the note, instead use the servo as a percussive note and move position on a beat division. Different speeds and lengths of movement will be perceptibly different acoustic sounds, so a whole host of ghost notes and percussion may be possible. Or, I have to ask, would slowing the position servo down make it quieter - arriving just in time? Lovely post next hope you return to it.

Bro can you please provide the 3d model and code of it please

your device is guaranteed to play Kalimba de luna

Very nice, interesting, and creative project! In my honest opinion, I would keep the servo noises as sometimes, in conjunction with the notes played, the servo noise sounds like its part of the song

Individual articulating arms to strike driven by servos tucked under to meffle their sound. The open nature contributes to the servo being so loud

Needs to be able to play more than one note, kalimbas are made for chords of two notes at once. I'd have gone for a music box style rotating mechanism with retractable pins, which would be able to play any combination of notes at ant time, and would fix the noisy stepper motor issue.

Very well done! Go bigger!!

I have a 21 key and Arduino UNO. I'm sure simple modifications could be made to play mine too.

You may look into replacing Arduino with an STM or smth else. Arduinos isn't as efficient and potent as many seems to think.

the servo noise is way too loud for this application

For X axis you can use mechanisms from CD/DVD drives. Maybe also for the 'finger' . It would be more precise and quieter. ruclips.net/video/gZRChEQj6y4/видео.html

the schematic diagram... nice 1:47

You are so under-rated. How was I not already subscribed?

This is exactly how a music box works.

super !

I've decided to revisit this project, likely after completing my current one. There have been many great suggestions in the comments, and I plan to incorporate several of them. Here's what I've gathered so far: *Larger panels *Replacing relay with solid-state switching *Tilting panels like a joystick to eliminate the need for a slip ring *Measuring motor current to detect end stops, eliminating microswitches. *Using smaller wires for signals Plans include creating a proper housing for electronics. I will share the improved project files once it's complete, offering a better starting point for anyone interested :)

I love how you shared your thought process. Great engineering, very enjoyable video, occasionally funny as well. 6:28 "The problem is: This table is very heavy. So, I won't go for this solution" LOL

it would be cool if the noise of the horizontal servo could change the tone of the noise it makes to play along with the kalimba.

Well, at least you added what amounts to be drums to the melodies.

this is beautiful :) you could cut down on the noise by reusing a floppy head mechanism for the lateral movement.
