How is this so underrated
seriouslly...wheres the 14 million views
I don't even understand
You may have been asking this rhetorically, but it’s because people don’t even realize this is in the realm of possibility. Unless you’re familiar with the tech (and the vast majority of people are merely content to just have their iPhones boot up regularly), you might figure this is possible, but in no way is it feasible for the average person. And this conversion is an intense process. I’m only familiar with Arduino tech because it’s mentioned on Nerdforge, and then it’s nowhere NEAR this level of intense. I got here because I searched “can you convert a piano to play by itself”. 😅
@@shibalady206 That's a surely enlightening point of view! we tend to forget how mesmerizing things can be, when we become familiar with them. Is that the true definition of magic? what could still be magic for tech nerds like us?
Self playing pianos are like 150 years old to be fair
now Tom can finally catch Jerry without having to play the song
Funny, I remember Bugs Bunny playing this.
@c.c.1366 Tom did it better ngl
I recently got the piano tuned, fixed some of the solenoids, and improved the general mechanics of some of the keys. I also updated the code and included some features that put more realism into the keys and sound.
The result is what you hear in this video (I only updated the audio). This is a major improvement from past models IMO. I'll keep tweaking parts of the piano to get better sound.
You could also put something like silicone on the top of the metals that press the keys to get rid of that annoying clicky sound.
MBMS yes, that would work. It’s just a matter of adding it to each of the rods and then repositioning all of the rods
Well yeah, it might take a bit of time but it will definitely save you a lot of noise.
The easiest way would be to use a glue gun, I think.
have a feeling its not necessarily the clicking from hitting the keys but the internal clicking of the solenoids
Hello Brandon! This project of yours became too much, my friend. I'm an Electrical Engineering student, and I'm in the mood to do a similar project to learn eletronic ♥️
Totally insane build! And to think that you did it at the age of 15? I'm thinking of building a player piano after my final exams and this project is definitely helping me out a lot! Keep up the great work!
Beautifully done! Congratulations... I spent 37 years working on various electronic organs, keyboards and electronic pianos. I'm 78 now, retired 18 years. It was a great ride while it lasted.
This is incredible. You are a genius and a craftsman sir. Bowing to you.
Imagine all the pranks you could pull with this XD
Like what?

Count yourself as one of the world's geniuses, Brandon! Welcome aboard!
WOW. This took dedication!
this is absolutely insane and deserves so many more views
What an extremely well-made and interesting video, Brandon. Exactly this structure I want to see on UA-cam: demonstrating the functionality, simultaneously as showing the process. Very well done, and thank You for sharing!
Best regards: Moses K. Frost
This is so very cool, I have 1926 player piano that is pneumatic and uses rolls. I would love to find a plain tall upright and add this to it. This will be great when you figure out expression (loud and soft playing of individual notes).
STECK pianos are sometimes used -- the Aeolian Pianola Company if I remember correctly
That is so cool ! I would love to hear how the westworld oppening sounds on it 😁!
Your mother must have wept when she heard this playing for the first time. She must be so proud of you.
I am astonished and loved the terrific video you made of the build. It's an inspiration for young kids.
This is so cool.
This reminds me of the Marantz Pianocorder player piano control system.
They used mosfets for the switching, and used solenoids to actuate the keys.
This is so cool.
I want to use midi files to control an actual piano, and this is very helpful.
And, Creative Engineering Inc. used the circuit boards from Marantz Pianocorder player pianos to control their animatronic shows. Most notably the Rock-afire Explosion.
I hope that you have a wonderful existence.
Good job! you need to design an extendable PCB for the shift registers and add a removable connector to the solenoids that will be less work to build/replace parts and more reliable then all the jumper wires on the prefboard... plus I would have added some kind of rubber padding to the solenoids to avoid them clicking...
Brandon, what you just did is totally jaw-dropping. I hope that you know that and keep it up! Cheers from Argentina
Amazing job! The new Steinway Spirio looks great!
🤣
This is a truly top tier, pro level accomplishment.
How this video only has 64K views (at the time of writing) is absolutely beyond me!
Insane! Genius! You can now patent it, as many acoustic pianos will come with this new feature: playing automatically.
Fantastic really well done. It does show how ingenious the victorians were. They did this in 1896 using just air. I have one from the 1920s, still works, even in a power cut. I am an electronics engineer and wanted to do this.
Hey Brandon!
I hit subscribe, hoping you will put out a random piece of music a week. I love watching your actuators.
I just gutted my upright grand to convert it to digital and was looking at what to do with the parts, but now you got me wishing I could invest the time and money to follow your lead!
Here's hoping life never prevents your from tinkering.
Cheers!
What a great project! Well done!
That took a lot of your work and energy to convert your ordinary piano to something completely phenomenal. But, at the end, all of that effort and energy you put in, paid off! Well done!!
Very cool, not quite as fun as pumping an original 100+ year old player piano pedals and watching it play music from a roll of paper while not using any electricity at all, but this is a very cool build. I may have to do this in my Knabe spinet so I can have the best of both worlds :) Well done!
Wow!! It's amazing!!
You are an absolute genius
This is wild man, this is huge. So cool.
Great work
Thanks for sharing
You definitely have completed a great feat in designing and building this player piano. I first saw this a few years ago and was interested in learning more, but work got in the way. Now that I have made time and would like to pursue a build, I have found that registering to join the discord site is not working and they don't respond to my requests for help.
BRAVO!!!
congrats on a really nice project! always wanted to do a MIDI mod to a piano, maybe someday
WOW. Very Talented.
This is absolutely insane ! Great job man !
Sooooo impressed! I'm thinking of doing the same thing. It was just an idea I had. Thank you for sharing.
oh my god. this guy an incredible genius
This is amazing 😍 thank you for sharing this👍👍👍
thats incredible❤🔥
Simply genius, Brandon!!☀️🌜🌞
Really really awesome, the exact perfect video that I was searching for. Really appreciated ❤
What an accomplishment!!!!
If it isn't a reproducer level of expression you can add a variable pot to the voltage regulation rail supply buss and have the expression like any traditional player. Instead of pumping hard or softly you'd have a lever pot or good slider pot to play with. Or use a volume pedal on the floor wired for the DC buss control.
Does that mean that you can set velocity (how loud a note plays) by deciding how much current you send to the solenoid? Isn't the solenoid on-off?
This is amazing. Nice work!
Now play rush E
Amazing work
I've recently considered making my own player piano, like this, and now that I see how much work went into it, maybe not. Or I'll just buy jumpers, instead of making them like you did, and do it anyway. Lol.
Or maybe I'll make a circuit board and avoid the jumpers altogether....
Anyway, this sounds and looks fantastic. Keep up the good work!
Absolutely delightful and brilliant. Great work.
Really impressive work. I'm a trained classical musician myself and I've been trying to get into mechanical instrument building so I can't begin to imagine how much effort something of this scale took. Surely the solenoids are quite noticeable? In my experience I've found the 'clack' sound it makes when it's activated quite distracting for performance
Perfect ! Congratulations!
mesmorizing! BRAVO! Had to take days and days
Awesome job! Although I can't help but wonder: is it safe to be pumping 24v @ 40a through solderless breadboards?
AMAZING 👏 AMAZING 👏 👏 👏
4:34 my favorite part of the song btw
No
It's my
My favorite part of the *piece* btw
This part is called Friska
What is this piece and who wrote it?
This is amazing, and this is basically a lost art-form these days. Everytime I hear this I picture the bugs bunny cartoon. 🤣
You know what would be a cool variation of this to try? One of these that’s human-controlled using Apple’s Mainstage (which allows a human player to play those same kinds of really complex chords and harmonies) in place of Synthesia or Piano From Above.
Awesome build!
Dude, you're amazing!
Bravo que impresionante. Tengo un piano para hacer lo mismo. Pero diseñare la PCB en ves de usar protoboards ....
- How many lines of code?
- Yes!
Impressive! Love this!
DAMN U R GENIUS!!
Awesome!
Imagine showing this to some peasant from the 1700s and you as a noble. You invite them over for dinner and then you clap your hands and then the piano starts playing by itself.
my first thought was to use an electromagnet (magnetic coil) on each key and a permanent magnet on the other side respectively.
This is still an incredibly cool and underrated project, but it seems to me that this way there will be almost no moving parts (electric motors don't last forever) and it will consume less power
Fantastic!
Cool !!
Incredible, well done!
this is so cool!!
This is insane Dude. Congrats!!! nice job! (subbed)
I am just speechless...
amazing guy...basically a genious
WOW
I am going to need something like this to play a original version of a concerto
Very nice work, sir!
5:31
I was surprised that it was this song cuz I love this part
Hungarian rhapsody no2 for anyone who sees this
piece*
I bet that pulls some amps if you play all the notes at once!! Amazing work!!! ❤️😎👍
Amazing!
Increíble! Eres un genio!
Bravo !
Do you sell them already assembled and just have to be installed?
respect!
Healthy and Friendly Greetings from the Netherlands!
Suggestion, did you set up another solenoid for the sustain pedal and map it to CC#64?
You are a crack !!!! Congratulations.
I fell in love with your project. I will work to match on my piano !!
I will tell you!!!
Greetings and again congratulations
GREAT JOB
This is one of the coolest videos I may have ever seen in my life.
What's the name of the piece that was played at 5:30 (great video by the way)
You had me thinking i might be able to do this myself at the beginning, but now i think i might just have to save up the 40k for one...
That's some next fcking level.
I want to learn how to do this with my bass, guitar drums and keyboards. So behind the learning curve dot-dot-dot
Great Genius
5:31 What are those cooling fan boxes on both sides for?
They’re power supplies
VERY COOL 😎 🤗💥👍🏽🙏🏽
Hi Brandon, I've worked out why the PWM stopped working, I asked it to serial print the velocity and found no change with different volume / velocity. Anyway on the pro micro on the piano just get it to ignore this line //velocity = round(velocity * (MAX_PWM - MIN_PWM) / static_cast(127) + MIN_PWM);
I sent you an email a few days ago I was having some trouble with the ESP but I've got it all worked out now. Hope this helps :)
Thank you! And sorry for not having been able to fix this issue. We’re doing some work in the house and there is a lot of stuff in front of the piano right now. This line is supposed to conform the raw MIDI velocity to work in the range of the PWM frequencies, and I guess it’s giving a fixed value somehow... I’ll update the code in the next few days.
@@brandonswitzer7112 All good thanks for the reply, Carl and I are looking at ways to get the PWM working nicely its quite buzzy and not working too well I'll let you know how we go :)
@@VK3ACU Yes. The buzzy PWM is something I tried to account for. The solenoids only utilize PWM when the key is in the process of being pressed. Once the key is fully pressed, the frequency of the PWM is set to its max. In other words, the PWM is turned off once the note is pressed, which stops the buzzing noise. Since the line that conforms the velocity is commented out, the PWM won't be set to its max when a note is pressed. A temporary fix for you might be to set MAX_PWM to 127.
@@VK3ACU I just updated the Github code with a possible fix to the PWM bug. Let me know if it works!
@@brandonswitzer7112 will do Brandon! Cheers
Beast mode
amazing. I loking for a similar project to play a percussion kit. I'll study you project. thanks
Nice!!!!! Subscribed 👍👍👍👍😁😁
so cool
Good Lord. I want to do this now....
WOW now thats a great Project! Maximum respect. I made a roll reader with a MIDI output, you made a MIDI acoustic piano :-) Any plans to modulate the intensity of notes? Maybe with PWM.
