I have never seen a resistor glow like that, and something about it happening twice and being completely unaddressed both times is truly part of the magic of these videos.
When the key is stuck the capacitor doesn't charge so the charging current constantly flows through the resistor instead of stopping when the capacitor is charged. The boring fix would be bigger resistors or less charging current. The slightly more exciting fix is to just solder as far away from the board as you can, so they still glow red hot but it doesn't catch the wood on fire. I bet electroboom calculated they would get a bit hot and that's why he said not to touch them, but he didn't account for keys getting stuck

I can see Jordan Rudess getting some insane combination piano/pedal steel guitar, including the ability to change dynamics on sustained piano notes like you can do with a guitar's volume pedal.
I think the reason your hammers weld together is because you are effectively using them as a switch causing inductive feedback causing a voltage spike high enough to weld the contact points, the solution is to add a diode in reverse bias to the end of your string, however that will clamp your voltage so you need to choose a proper diode that will produce a good enough arc but not weld the contacts.
This man has ONE gimmick and freaking never stops amazing me. Everytime you upload something new I always have to watch cause i already know it's going to be time well spent.
Suggestion: put some plexiglass or other clear material as a casing around the hammers and strings, so A, its less likely to shock you, and B, it will muffle some of the pop sound while still letting you see the sparks. You could even try putting a colored material to see if you can make the flash different colors.
@Ian Visser You're unlikely to get that type of glass in a large enough pane to cover the whole piano, but it's possible to pilfer the glass from a few dozen welding masks and tesselate them in some fun patterns with silicone to fuse 'em together. Think of it like medieval glasswork- back in the day, glaziers couldn't get consistent large panes like we do nowadays, so they made smaller 'blobs' of glass and connected them with lead lines.
It might also save your life if one of the strings gets damaged enough to break. Those strings are under an insane amount of tension and could cause a lot of damage if they release in the direction of you

Yeah the part where he soldered everything except the wire and the solder was in one big blob refusing to stick was so relatable. Only thing missing is melting the components with your soldering iron because the goddamn solder won't stick. Source: I suck at soldering. Especially piezo speakers, DC power connectors, constan wire and some other stuff
Yeah I also loved the ethics:) A waste of time and a waste of resources just for a herd of ignorant a$$holes with the attention threshold and the environmental awareness of a housefly (That is usually the TikTok niveau) ... just to make a buck of it.

Considering you've never soldered before, that was actually a half decent job. Sure it's not pretty but the connections all look good. You can also definitely see your progress. Now when a wire breaks, you'll be like some of us and get excited because you can easily fix it yourself.
Ive welded over plywood and 2x4s alot. they dont catch on fire until there is a high concentrarion of sparks hitting one area over and over for a good while, like itll start smoking and shit first. That being said, if you played a chord in repitition, it could definitly catch on fire lol
fortunately, the wood was thick enough and the wood fibers weren't fraying to actually catch a spark. sparks dont carry enough heat long enough to light solid wood on fire. need kindling of some sort (think of wood shavings). constant electricity through wood on the other hand....

Mattias. I just discovered your channel. And I wanted to let you know: “Actually now when I think about- no. Why start thinking now?” Is my new life motto.
First we had ElectroBOOM's electric guitar, now we have an electric piano, next we need some kind of electric percussion and then we've got a whole band. The name of the band should definitely be ACDC, or because of the full bridge rectifier, maybe just DCDC
Dude, mad respect. You had an idea and even being scared and lacking experience, you did it anyway and got help as needed. You probably also learnt a lot! PS: I read the tags of videos, lol

@@Altropos i did a thing does things surprisingly save and "predictable" and makes it look dangerous. sure what he shows isn't "save" but if done right it isn't that dangerous either.
You need to make an album. Mattias Krantz and his electric piano, featuring such pieces as "Electric Blue Danube", "Total Eclipse of the Spark", "Theme to The Legend of BZZZelda", and the immortal classic, "Current Flows in You". The sales would be shocking.
This is the most cursed engineering project I have ever seen- and I’m a fan of Electroboom so that’s saying a lot! Also, she’s you’re actual piano teacher now! That is SO cute!
I absolutely love the trial and error and problem solving involved in this project. I'm so glad I've been here to watch your journey from essentially the beginning!!
I remember when you first had to hire pianists and people to view your crazy builds, now you get them volunteering to try them out! You have come a long way Mattias!
I wish you could hear them IRL haha. The peaks of the audio gets so limited here. I was seriously suprised how loud it was, it was really like having fireworks pop just in front of you!
Electroboom warned me about this problem. However, during the hundreds of hits on the prototype the hammer never fused with the string even though I used the actual piano strings on it. That’s why I was so surprised by it doing it on the piano. But I guess it has something to do with either the strings not being under tension on the model or that the hammer action on this piano doesn’t have the same action/bounce as the action on this piano (Really love when Tubers show a paragraph of important detail in mess than a microsecond.
A few ideas for improvements if you intend to feature this piano again: If you add an inline circuit breaker, you can eliminate the problems with the resistors lighting up like that. Also worth noting that your resistors could stand to either be higher resistance (ohms) or higher wattage. More ohms means the caps will charge more slowly but will make the whole system a fair bit safer, higher wattage will allow the capacitors to charge faster without the risk of the resistors burning when the keys stick. Might also be worth a single big heavy resistor on the input to limit the system as a whole, it won't use as much current on startup and when playing many keys at the same time or in quick succession.
@@mars5train601 Good call, but I was looking mostly at the fact that the resistors were burning under sustained draw, the reduced inrush would be added bonus. Perhaps both would be a good idea?
Thanks! Yes I was thinking of adding the a fuse in the circuit but I got lasy and just skipped it... For the resistance, I wanted the piano to charge faster than you could physically play the keys on this particular piano. You can play around 5-7 notes per second on this one. With the doubled up capacitors each capacitor charged to 3T in 200ms so anymore resistance and the charging would be too slow. The reason I didn’t want to make it ”more safe” was because the word safety and a project like this is not really compatible 😅even if we doubled the resistance, the resistors would start glowing like that either way when they fused. Only difference would be the piano would also charge less epic time. This video looked a bit spontaneous, but there was a few weeks of me an mechatronics engineer just discussing every possible way we could make this. Appreciate the ideas🙏
You had an idea, and despite every obstacle and the fact that you had extremely little relevant experience, you went out and did it anyway. Absolutely incredible. You're a true youtube hero
The chaotic nature of the project itself and the off-screen meticulous planning really comes through. I’m equal parts terrified and curious about making my own

If anyone's curious, for future reference, you can play RUclips videos frame-by-frame by pausing and using (I think) the comma and period keys. It's good for those fast text moments.
Pianos are classified as a percussion instrument due to the hammer action. Even though it uses strings, it isn't a string instrument because the strings are hit, not plucked or strummed. Same reason why brass bells are percussion instruments and not part of the brass family, despite being made of brass.
@@cheeseboy847 It depends on the way pianos are being applied. Generally, pianos have more of a hand in complex, solo repertoire the way other string instruments do - but in different circumstances when they are used to create a background environment, they definitely are.
There are 3 types of sounds in this: 1. The sound of the strings (the actual piano sound) 2. The mechanical sound of the metal hitting metal 3. The electricity sound of the sparcs The level of creativity it's really huge here. This guy is a combination of art, creativity, science, engineering, curiosity, bravery and ambition. I really hope he doesn't get decouraged ever because his ideas can be weird or too hard to make them.

Some suggestions from an electronic designer: - place one 330 Kiloohm resistor (2 watt) in parallel on each capacitor, this modification allow the self discharge of all capacitors within few minutes (for safety purposes!). - place one 10 Ohm - 5W resistor in series with each hammer to limit the current (this should decrease the risk of a welded hammer) - buy a variac to adjust the input voltage (to adjust the intensity of the sparks) - put some grease on both the hammer and the cord (to decrease the risk of welding) - replace the 270 Ohm resistors with 1000 Ohm - 20W resistors (or two 2200 Ohm - 10W in parallel) and place them few millimeters above the board to avoid burns issues - have fun! 🙂
When you play this instrument not only is it an impressive sight to see, but it's like you're playing 2 instruments at once! Piano and some electric percussion instrument!
Of all the videos I’ve seen in RUclips, never have I ever thought that I’d see a collab between a pianist, and an electrician (who’s also known for blowing things up)
I'm an electrical engineer. It is hunting me to watch what you're doing to the instrument, but this is exactly the piano to play some AC\DC. Nice project. I'm impressed you didn't get (much) electrified. Cheers
Let's call it an electric spark piano. If you give it to a really talented musician, you know like the kind that make their own musical timeless pieces, I am sure that person would be able to produce music that benefits from the sparks.
This was very enjoyable to watch. I love seeing the process, and for someone who has never worked with electricity, wow, very impressed with what you did. And you sense of humor or calm demeanor is very engaging.
This is just awesome! As someone who is both a piano player and studying electronics this makes me happy! :D I'm actually curious if this made you more familiar with basics of electronics like reading wiring diagrams, how each component works and what it does and so on?
Thank you! Yes definitely. Well not this project so much, because it all went so smoothly. But a longside this I was working on a tesla coil piano and I spelt many days reading electronic books to problem solve. I might talk about that next project:D and good luck with your studying, electronics was actually really fun
I didn't think you could go further once you put those hammers on the piano, but after this I know you can do much more! I wonder what kind of crazy project you will bring us next
At 13:38 the resistor was glowing because one of the hammer was continuously touching one of the string (hammer got welded to the string) as a result continuous flow of the current occured and heated the resistor enough to glow... Anyways great project...!!👍
As someone who has had the pleasure (and pain) of playing with flash capacitors myself, the first mention of disposable cameras put a wild grin on my face.
Hey great stuff! Just a suggestion to help you not hurt yourself soldering. Hold farther down the solder so you have about 2-3"(5-8 cm) between your hand and the material you're soldering. And tin the soldering iron before you start. To tin it, you just need to melt a small amount onto the end of your iron. It helps to make the first few joints properly. But otherwise good stuff! Not bad for a first timer 🙂

The fact that you're actually taking piano lessons from that piano teacher now is the most adorable and heartwarming thing to see
"It exploded!"
"It's supposed to!"
I think the reason your hammers weld together is because you are effectively using them as a switch causing inductive feedback causing a voltage spike high enough to weld the contact points, the solution is to add a diode in reverse bias to the end of your string, however that will clamp your voltage so you need to choose a proper diode that will produce a good enough arc but not weld the contacts.
I'm not sure what I'm more impressed by, the commitment and courage, or the fact you actually LEARNED PIANO!

@@Crazy___Ginger Thank you for dropping the name, I just listened to it and started crying a bit. Such a lovely piece
You're getting dangerously close to an "I set my house on fire by making a flamer piano" episode
Suggestion: put some plexiglass or other clear material as a casing around the hammers and strings, so A, its less likely to shock you, and B, it will muffle some of the pop sound while still letting you see the sparks. You could even try putting a colored material to see if you can make the flash different colors.
@Ian Visser You're unlikely to get that type of glass in a large enough pane to cover the whole piano, but it's possible to pilfer the glass from a few dozen welding masks and tesselate them in some fun patterns with silicone to fuse 'em together. Think of it like medieval glasswork- back in the day, glaziers couldn't get consistent large panes like we do nowadays, so they made smaller 'blobs' of glass and connected them with lead lines.
It might also save your life if one of the strings gets damaged enough to break. Those strings are under an insane amount of tension and could cause a lot of damage if they release in the direction of you
I'm not sure, but I think the flashes would damage the plexiglass, and eventually it wouldn't be clear anymore
@@fableagain Yeah, the sparks would probably start melting the plastic slowly but surely
@@MrCh0o If not that, the fumes and dust will stick to the glass.

that was the most out of depth I have ever heard a human being find out they are.
For someone who works with PCBs and hardware, your soldering was very impressive, especially for a first time. Incredible video idea and incredible work ethic
I know right.
Sure better than me as a kid and the last part better than my prototypes on Chinese perfboards at times😂
Yeah the part where he soldered everything except the wire and the solder was in one big blob refusing to stick was so relatable. Only thing missing is melting the components with your soldering iron because the goddamn solder won't stick.

Indeed, especially very old, dry wood coated with varnish
Ive welded over plywood and 2x4s alot. they dont catch on fire until there is a high concentrarion of sparks hitting one area over and over for a good while, like itll start smoking and shit first. That being said, if you played a chord in repitition, it could definitly catch on fire lol
fortunately, the wood was thick enough and the wood fibers weren't fraying to actually catch a spark. sparks dont carry enough heat long enough to light solid wood on fire. need kindling of some sort (think of wood shavings). constant electricity through wood on the other hand....
well they do.... just not in your favor lol

indeed , totally looked pro at the end
when doing a thing, you slowly figure it out in progress
First we had ElectroBOOM's electric guitar, now we have an electric piano, next we need some kind of electric percussion and then we've got a whole band. The name of the band should definitely be ACDC, or because of the full bridge rectifier, maybe just DCDC
definitely DCDC. can't name it ACDC or someone's gonna get to know a few lawyers
Actually, the full bridge rectifier turns AC into DC. So AC/DC is actually appropriate, although keep in mind the lawyer thing lol.

Try putting the sparking bits in a glass case to muffle the snaps. Also, you can use hard rubber for the keys to eliminate need for gloves.

first ask the craziest person in that subject you know on how to do it and then ask someone who is still sane and let him do the major calculations for you. the first one you just asked the questions to know what you should be extremly carefull about and how to not do it if the other person wants to do it in another way.

You have come a long way Mattias!
The percussion from the sparks was a really cool addition.
I wish you could hear them IRL haha. The peaks of the audio gets so limited here. I was seriously suprised how loud it was, it was really like having fireworks pop just in front of you!
Electroboom warned me about this problem. However, during the hundreds of hits on the prototype the hammer never fused with the string even though I used the actual piano strings on it. That’s why I was so surprised by it doing it on the piano. But I guess it has something to do with either the strings not being under tension on the model or that the hammer action on this piano doesn’t have the same action/bounce as the action on this piano
(Really love when Tubers show a paragraph of important detail in mess than a microsecond.
A few ideas for improvements if you intend to feature this piano again:
If you add an inline circuit breaker, you can eliminate the problems with the resistors lighting up like that.
Also worth noting that your resistors could stand to either be higher resistance (ohms) or higher wattage.
More ohms means the caps will charge more slowly but will make the whole system a fair bit safer, higher wattage will allow the capacitors to charge faster without the risk of the resistors burning when the keys stick.
Might also be worth a single big heavy resistor on the input to limit the system as a whole, it won't use as much current on startup and when playing many keys at the same time or in quick succession.
Found the friend that encourages people to pursue obviously terrible ideas.
And I’m here for it.
On that last point, an inductor would be better suited to help with inrush, since it limits large changes in current draw
@@mars5train601 Good call, but I was looking mostly at the fact that the resistors were burning under sustained draw, the reduced inrush would be added bonus.
Perhaps both would be a good idea?
Reading your discussion about how to optimize this piano makes me wish this is pursued to make ready for market.
Thanks! Yes I was thinking of adding the a fuse in the circuit but I got lasy and just skipped it... For the resistance, I wanted the piano to charge faster than you could physically play the keys on this particular piano. You can play around 5-7 notes per second on this one. With the doubled up capacitors each capacitor charged to 3T in 200ms so anymore resistance and the charging would be too slow. The reason I didn’t want to make it ”more safe” was because the word safety and a project like this is not really compatible 😅even if we doubled the resistance, the resistors would start glowing like that either way when they fused. Only difference would be the piano would also charge less epic time. This video looked a bit spontaneous, but there was a few weeks of me an mechatronics engineer just discussing every possible way we could make this. Appreciate the ideas🙏
the piano teacher's reactions are golden
Should I touch this?
NO, DO NOT TOUCH ANYTHING!
I haven’t even got to that bit yet, and I can already know I’m going to agree…
the amount of anxiety this video gave me is unreal, but it's such a cool piano and I'm glad you were able to make it fairly safely!
I agree 100% hahah. I’m not sure if it was very safely 😅 Thank you!
You had an idea, and despite every obstacle and the fact that you had extremely little relevant experience, you went out and did it anyway. Absolutely incredible. You're a true youtube hero
The chaotic nature of the project itself and the off-screen meticulous planning really comes through. I’m equal parts terrified and curious about making my own

If anyone's curious, for future reference, you can play RUclips videos frame-by-frame by pausing and using (I think) the comma and period keys. It's good for those fast text moments.
19:04 rhythm is really brought out here. It's a percussion instrument at the same time almost. It adds in the same way tap dancing does.
Pianos are classified as a percussion instrument due to the hammer action. Even though it uses strings, it isn't a string instrument because the strings are hit, not plucked or strummed. Same reason why brass bells are percussion instruments and not part of the brass family, despite being made of brass.
@@cheeseboy847 It depends on the way pianos are being applied. Generally, pianos have more of a hand in complex, solo repertoire the way other string instruments do - but in different circumstances when they are used to create a background environment, they definitely are.
@@laurynk4209 I can see what you mean. It could be both due to it resembling a harp or lyre, but one played with percussive tools.

You need a heatsink for each resistor and pair of caps. That will ensure they don't overheat and burn out.
Some suggestions from an electronic designer:
- place one 330 Kiloohm resistor (2 watt) in parallel on each capacitor, this modification allow the self discharge of all capacitors within few minutes (for safety purposes!).
- place one 10 Ohm - 5W resistor in series with each hammer to limit the current (this should decrease the risk of a welded hammer)
- buy a variac to adjust the input voltage (to adjust the intensity of the sparks)
- put some grease on both the hammer and the cord (to decrease the risk of welding)
- replace the 270 Ohm resistors with 1000 Ohm - 20W resistors (or two 2200 Ohm - 10W in parallel) and place them few millimeters above the board to avoid burns issues
- have fun! 🙂
Also install a small isolation transformer to prevent the entire metalwork of the piano from becoming live.

I think you could tune the sparks like a music Tesla coil, but that would be quite complicated
I’ve worked on that for months actually!
This is just awesome! As someone who is both a piano player and studying electronics this makes me happy! :D I'm actually curious if this made you more familiar with basics of electronics like reading wiring diagrams, how each component works and what it does and so on?
Thank you! Yes definitely. Well not this project so much, because it all went so smoothly.

It's both beautiful and terrifying at the same time.
At 13:38 the resistor was glowing because one of the hammer was continuously touching one of the string (hammer got welded to the string) as a result continuous flow of the current occured and heated the resistor enough to glow...
Anyways great project...!!👍
Love that you played AC/DC for the demonstration. I actually never thought that I wanted to hear Thunderstruck on a piano.

As someone who has had the pleasure (and pain) of playing with flash capacitors myself, the first mention of disposable cameras put a wild grin on my face.

For your next episode, you should 3D print an entire piano, with filament strings and the scratchy keys
This is the best custom piano you've made so far!
You just need to beef up your circuitry to handle higher currents so your resistors don't burn up!
Hey great stuff! Just a suggestion to help you not hurt yourself soldering. Hold farther down the solder so you have about 2-3"(5-8 cm) between your hand and the material you're soldering. And tin the soldering iron before you start. To tin it, you just need to melt a small amount onto the end of your iron. It helps to make the first few joints properly. But otherwise good stuff! Not bad for a first timer 🙂
