Everytime i learn something new from your video like midi and many more. Keep uploading

[@AdityaMehendale]

Hi, Great project! Grabbing the glass-bases down hard onto a non-dissipative surface (granite or concrete instead of wood) will give a higher Q-factor of resonance, and make for louder and cleaner notes. Also with the wooden (future) instrument, the place where you clamp the wood makes a lot of difference to the note. Clamping on a node of a modeshape with an elastic element should work the best!

[@samelie]

Good fun!! Love the musical projects. A wine glass on a controlled 'lazy-susan' with a rubber finger to make the ringing sound would be silly. We had a concerto at a party once with everyone filling their glasses and rubbing those rims. oh baby

[@bardenegri21]

I think using wind chimes instead of glasses might sound better and be easier to keep around the house for more than a day (the water evaporates). Could be fun hanging from the ceiling next to the custom light. Fun project anyway, I love it!

[@bitluni]

hmmm, I like the Idea. It's especially cheap when cutting a simple steel pipe.. I'll consider that

[@tbbw]

Lol flight of the bumble bee... i use that as a page tone on my bbs :)

[@bitluni]

YES! I had to try it... it's the best for testing if you don't have to perform it yourself. lol

[@ChitranjanBaghiofficial]

Honey every one is waiting for the wine glasses to start the party. Meanwhile in the basement

[@edgaut9808]

Flight of the bumblebee and Tetris were recognisable. Cool project!

[@bitluni]

Correct!

[@PhG1961]

Excellent ! Very entertaining on a hot summer evening.

[@ninetailscosmicfox5585]

That pro micro knockoff looks really fun for circuit bending and such

[@rsmeaton]

Nice! Though beer bottles + solenoid valves, and an air pump might sound a little better.

[@nihorothereal]

Great job! Can you make the solenoids quieter by some rubber rings to dampen the movement endpoints? An maybe shield them in some microphone fur? I could even think of modifying their signal, to not be jerky, but a smoother curve. But that's probably overkill ;)

[@brendanbyrne8862]

Great project. But why didn't you have the solenoids make contact with the wine glasses and cut out the need for 3D printed mallets?

[@UnexpectedMaker]

I only got the Tetris theme :(. Great project though!, how many glasses did you break?

[@bitluni]

Just one :-D

[@UnexpectedMaker]

Wow, Impressed!

[@bitluni]

Tetris was right btw!

[@mandarin1257]

Korobeiniki

[@mattiacastello2267]

Maybe too common, but using a xylophone, already tuned and maybe using it as phone ringtone when a call comes, using ifttt will simplify the project on the phone connection side, anyway great videos

[@tuttutfreeman4506]

Hey, I’m really impressed with this, well done! I have a question, if you get a minute... Did you manage to make this with velocity control? Any idea how one would do this. Thank you!

[@JeremyCook]

Nicely done!

[@AlexHuebi]

Auch wenns jetzt schon fast ein halbes Jahr her ist: gelungenes Video. Habe ich die 3 richtig erraten? Tetris Hummelflug ??? - welches war den bitte das dritte? (von OOT - Zelda) Salias Lied

[@casholsen5848]

I have an old piano harp in the backyard, maybe this would bring it back to life.

[@bitluni]

Self playing pianos were always fascinating... imagine connecting it to a sensor and whenever someone enters the room it plays a ghostly tune

[@pleisterman8660]

If you could use the mallets to dampen the sounds of the glasses to shorten the time a sound is played it would sound a lot better.

[@Adamski102]

Perhaps servos would be less noisy and you could control impact force...anyway a thump up for your passion and dedication.

[@schrabbels]

Echt genial! Mich würde interessieren, ob andere Flüssigkeiten auch anders klingen😏 es gibt doch bestimmt auch einen Klangunterschied zwischen warmen und kalten Wasser 😀

[@bitluni]

das ist ne gute frage... ich habe mich auch gefragt was passiert wenn man stahlkugeln nimmt :-)

[@mandarin1257]

Korobeiniki/Tetris Theme A and Flight of the Bumblebee. Also 20th century fox theme at the start.

[@zolatanaffa87]

Why do not put Rubber studs on the bolted side of the solenoids moving part avoiding the building. of the plastic hammer?

[@RaphaelAguirre]

Very cool project sir!

[@ytfp]

Awesome! Can't wait to see the wood? one..

[@bitluni]

Ok that is actually a teaser.. I'm not yet sure if I can produce enough force using the actuators but it would be cool for the bass

[@AdrianoFiorenza]

haha nice one! you use blender a lot, I like that! I'm eager to watch your 3d scanner mark II video!

[@freeelectron8261]

Maybe a Wind Chime version with cut tubes instead of glasses. Might be easier to tune as well.

[@lightdark00]

Add an entryway sensor and have it act as an alarm or a welcome home to you. Then for Halloween have an outdoor version that scares kids as they walk near! 😊

[@bitluni]

hmmmm... nice idea... making it an IoT device... It plays different tracks on specific hours etc

[@DerekPicard]

Great Job!

[@TannerTech]

Awesome video dude! Could you add explanation comments to your code? I just looked at it on GitHub, and don't understand a few parts of it. I was looking to modify it for musical Christmas lights!

[@bitluni]

Hey it's Tanner Tech! Tanner Tech Tanner Tech..... I like your channel! Sorry about the missing documentation, as always everything rushed.. youtube punishes if I take longer for quality... there are exactly two comments //note on and //note off lol the code is based on the read write examples from the midi library.. just added pwm output.. but I'll add some explanations

[@TannerTech]

bitluni's lab Awesome! Thanks dude! I totally understand. KZbin punishes time, that is annoying haha.

[@lalchandra4590]

wow. Nice instrument.

[@alphasatari]

Quality content!

[@Rtcmanga_YouTube_Channel]

Awesome project!! Incredible!! :)

[@poweredbysergey]

Cool

[@grindel80]

Great project!!

[@RenatoPernett]

As usual, very very inspiring! Thank you for sharing these projects man...

[@synterr]

I need these Teufel speakers! :)

[@delusiongaming2506]

Awesome!Can you plz make electronic basics vids?

[@bitluni]

I could try!

[@delusiongaming2506]

bitluni's lab thanks you bro!

[@narinoguerra7656]

Hi Bro, Excellent, Thanks for Sharing...

[@avejst]

Wow, interesting project Thanks for sharing :-) Remember to drink water in this summer heat ;-)

[@joetke]

How to locate neurons by hammering someone's skull at different spots using tada! MIDI... Inspiring indeed.

[@sallerc]

Cool project! :) But the glasses doesn't sound so good, not so clear notes.

[@grindel80]

Why you decided to use 12V Selenoids? (There is a 5V Version available)

[@davidrubio8673]

12v solenoids have more torque

[@becopta]

Dude, youre awesome!

[@bitluni]

Thanks!

[@joetke]

Makes me thirsty... 35°C outside on Strasbourg, France... can't focus on your explanations... too hard...

[@AtomkeySinclair]

Hahaha! Neat. But you gotta upgrade the cheap glass glasses to crystal glasses. Average 50$ a glass. But beautiful sound.

[@bitluni]

I will... you find the donation links in the description :-P Still payed 5€ per glass... that really sums up... even though the is no particular expensive part its just the mass

[@kezi___]

really consider freecad, i don't know how you can use blender to do any cad work without getting insane, sure freecad is not that user friendly but at least it's made for the purpose

[@bitluni]

I will.. I even have small filler video in mind for that!

[@John2009R]

If you already know Blender it works quite well. There are 3d printing tools built in.

[@kezi___]

no, it's terribile, and the 3d printing tools are almost useless (they only fix when blender itself screws up) it may be ok for creating and printing toys but for mechanical parts a parametric cad is 100 times better

[@John2009R]

If you are starting out modelling for 3d printing I would not recommend Blender either but if you have been modeling in it for a long time (15 years in my case) you can get good results quickly for 3d printing. Even mechanical parts. Here is an RC boat I am working on kzbin.info/www/bejne/gZfHcnqEj7aqn7s Admittedly, it is a toy.

[@RichardT2112]

Now play Axel F ;)

[@Wobblybob2004]

12 notes in an octave?

[@nrdesign1991]

counting the semitones oviously

[@bitluni]

It's rather acoder point of view every semitones are equal to me :-D en.wikipedia.org/wiki/Twelfth_root_of_two

[@jvqn6581]

Can't believe none of the comments so far said Darude Sandstorm...

[@hermannpaschulke1583]

Please play the mii channel theme

[@ArduinoClub]

I made it easier and it sounds nice. There is a video on my channel

[@IamLikki]

This is genius!

[@KJW648]

Sounds like the early electronic pinballs

[@bitluni]

those ware also driven by solenoids

[@ReevansElectro]

It all sounds like rap "music".

[@bitluni]

probably none of the artists were rappers.. but two of them are long dead so I can't ask

[@SparkOutUs]

dont knock a full glass of water onto your circuits like a dum dum ;)
