Pretty sure Medhi over at ElectroBoom would love to come see it. Oh, you mentioned him later in the video. Didn't know he helped you with it. Must've missed that video.
I would definitely secure that cable... You never want a 230v live cable flying loosely around... Imagine tripping over the wire and getting electrocuted while hitting the ground because you ripped the cable off
@@Mattiaskrantz At least until it catches on fire that is? 😅 (But my electrician advice is to add a strain relief to the cable so you don't accidentally trip on it and pull the live wires out. And I would buy a safety isolating transformer and plug it into that, then you won't get shocked as easily)
Considering you've already made two elemental pianos (water and fire), may I suggest you complete the 4 elements with wind and earth pianos? The wind piano could be made of pull flutes or something, and you could replace the hammers for rocks for the earth one. Like a flintstones piano
I wanna make an airgun or leaf blower piano that just forcefully blow on the strings then put piano pickups under strings. It’s such a bad idea haha because it so inneffective. But would be fun

I don’t think I can resist commenting. The capacity of this piano to surprise people is electrifying. They were just like, “Ohm my god, what did you build?” What is so shocking is that even after knowing, they’re still amped to help you, and not bolting out of the door! … I’ll see myself out.
Having worked both as an electrician and an electrical engineer, I'm not surprised by their reactions. Electricians tend to be a LOT more cautious around electricity and electrical engineers tend to be rather casual about it. I LOVE this series and am excited to see what's next for the electrical piano.
I've not worked with, but I know people of both professions and all the electricians I know are very safety concerned. But that is kind of their job. Same with the engineer, his job is to see the possibilities.
@@Mattiaskrantz You've escalated with every build. The electric one was way beyond what I thought would be your ultimate one. You're telling me you got something worse in store? I have to see it!
The reason is simple. Engineers engineer stuff most of the time … the electricians are in the field and work with it and likely have seen how quick things go south.
i really like how this time you didn’t “prank” the people you called over (given that this is a far more dangerous piano than the E one for example. that one can only harm one’s ears and heart lol), and they were both genuinely interested and curious about it. i wonder if it ever came to something? did they figure out a way to make it safer? will you continue working on it or is it a bit of a lost cause?
The first guy already mentioned how to make it safe: insulate it, but then again you want openness for letting the sound emerge properly from the piano. A middle ground could be: insulating anything directed at the player and make a spark box of sorts around the hammer section so the sparks would land on places that will never catch fire. Also regarding the glowing resistors, a different setup might be required to resolve that one.
The proper "electrician" for this piano is a high voltage electrical engineer, the same type that works / engineers high tension power lines and the switches for them. They deal with contacts that have to survive high voltage loads and switching on and off and will give you the best advice, but even they will have to think outside the box, because the gear they usually use is WAY too big to fit in that piano! As for bad ideas, sorry but in this genre, you have one upped me all the time so far, still I love seeing where you are coming from and where you are heading Mattias!
I'm an Electrictronics technician, and I really couldn't think of many more ways to make it safer, but there's something really simple that could make it a little bit safer: About that power cord that could be pulled out or maybe it could come off if someone tripped on it, you can make a knot on it from the inside, so if someone pulls it, it gets locked on the knot, and doesn't come out 👍👍
I know one way to help make it safer is disconnect it from the power supply, wrap the whole thing up in about ten layers of plastic sheeting, dig a giant hole in a field somewhere and burry the piano
@@Mattiaskrantz You should find an actual engineer (who does large structural stuff) to look at the piano and then act like he's a colleague and you just want a peer review done
Theory: Mattias isn't making pianos for the sake of making pianos. He's trying to set up a home defense by ensuring that absolutely NOBODY will want to go to his house and review his pianos. I think he's pretty close.
Would be really cool if it had a foot switch to charge the capacitors so they weren't charged at all times. Like you could play melody then hit the switch to have sparks on a chord or something
We had this when I went to Germany to the pro pianist. We played firework by Katy perry and then during the chorus i Started the piano with pedal. It was epic
You can put a non-conduct varnish on the wood to avoid fire by sparks. Also, you can use a more thickness cable to the drain part (conected to strings).
Kudos to your two guest experts for being such good guys about it. When the Norwegian electrictrician said "I don't know why I'm here," I thought that it's probably because he was willing and speaks excellent English.
As soon as the electrical engineer started playing the piano I could see how excited he was by it, he was confused at first but you can tell he really enjoyed the concept and wanted to experiment with it
There are a few ways to make this much safer. Add an isolation transformer before the rectifier (or back to back transformers to step down / step up - you can also adjust your output voltage this way too). Possibly a cheap ZVS circuit module could generate the high voltage from batteries and feed each capacitor via a resistor to the main bus - this removes the mains completely and makes the piano portable. Add a suitable input fuse (won’t cater for most shorts here but still worth having). Use bleed resistors on each capacitor. Use a glass panel or plastic panel which blocks UV (not sure how significant the UV component is compared to say a welding arc).
I was thinking it needed some plexiglass. I'm glad you installed some. I think the concept would look awesome at a concert with the right design and implementation.
Electrician with industrial controls experience here. Have some ways you could make this much better / safer, however you'd basically have to start the build over to implement some of these ideas. 1) using the bare metal of electrified hammers and your piano strings in order to directly run the power circuit is actually, properly insane. It would be a far better solution to mount a small bracket that holds your conductor on the side / top / etc of your hammers which would make a connection with a 2nd bracket to the side of / behind the piano strings at the same time as the hammer lands. Using pieces of flexible metal that can slide up against eachother as the hammer moves forward / backward would be ideal, and these two changes would help keep your piano's sound much more normal and eliminate wear. It's also worth noting that the far more obvious (but admittedly far less fun) solution to this would have been just putting a low-pressure push button below each of your piano keys that completes the circuit when you hit the key. But again, way less fun. 2) Relays fired with low voltage. Right now it seems like you're running your circuit's load directly through the circuit connection. This is bad for *many* reasons. What you could do is have a power supply that produces a low voltage like 12v hooked up inside your piano which would be used for separate, "controls" circuitry. This 12v is what you would actually be running through the wires on your piano hammers. From there, the completed circuit would fire the coil of a relay which would then separately connect the higher voltage power to the capacitor in a MUCH safer manner. This plan would also massively reduce or eliminate the electrical arcs thrown around near (or at) your fragile piano strings due to the load drawn by a single relay being essentially nil and the 12v being far less dangerous / air-arc-ey in general. 3) install plexi-glass tubes over each of your individual capacitors. This will help contain the sparks thrown by the capacitors, limiting the amount of fires you start inside your piano. This would also make it way more visible which note is being played as it'll only light up a single pillar above the capacitor rather than "exploding" out everywhere. Hypothetically speaking, you could even run them out the top of your cover like an organ and thus be able to play the piano with all your exposed electrical parts safe from being touched. I doubt you wanna mess with this project anymore than you already have but I'm happy to answer questions about this or generally discuss it with you or others here =)
Some random piano ideas: - A piano that plays like another type of instrument, such as wind or percussion. (Like the guitar video) - Rube-Goldberg style piano to play each note - A piano that fires nerf dart/pellets either at the strings or they keys - A really tiny, but functional piano - A piano that can be controlled via computer and can play itself (I think you may already have this?) - would be cool to connect it to one of those floor pianos you play by jumping on/with your feet - Gaming piano with haptic feedback (such as the stool and keys vibrating - plus lots of RGB) - Just a really loud piano
I just cackled when that was mentioned because if there's anyone who would actually do this live, it'd be Flake from Rammstein I could see making some sort of contraption for his synth to control a Tesla coil on top of the insanity of their pyrotechnics.
I've been watching (and enjoying) your content since the first one of your piano experiments came out and I would just like to say, you never fail to entertain. Every one of your videos is amazing and and I admire your creativity and problem solving skill. As a musician who wants to study engineering, you are such an inspiration.
@@windyr The jump cuts made it seem like you went from "horror" to "fascination" over the piano, straight into "this is stupid let's just screw around"
here's a piano idea: make a piano that, when you push a key, compresses a mini bellow which blows air through the corresponding note on a harmonica. You would probably need chromatic harmonica to get the notes you need, and then it's only 4 octaves, so you would probably have to only use the 48 middle keys on the piano.
@@Mattiaskrantz Yeah actually it is pretty similar, although in the case of organs, there's usually one set of bellows (electric or pedal powered) which blows the air through the reeds depending on which key valves are open. I always thought it would be interesting if there was an instrument where pressing on the keys actually provided the air pressure instead haha
So a few things to make it safe: 1. DECREASE the wire gauge -- just to be safe (14awg should be fine) 2. Tied ALL of the capacitors to a common neutral, and then add a SWITCH to "turn off" the sparks, which discharges the capacitors through a high current resistor -- and add a voltmeter to this neutral. 3. ADD a grommet to the cord coming in (and relocate near the bottom of the piano) 4. INSULATE the PCB onto a thermally safe material 5. Add a series of thermal sensors to check for overheating of the resistors and cut power to that key / group 6. Add an interlock cover OVER the top, where you CANNOT open the top unless you turn off the power (and then it discharges) 7. Add a brush and guide that will apply the necessary paste in an easy manner 8. Add a "timer" to detect if a key gets stuck, which will disable that key/group if the circuit is closed for too long (just disables the circuit to ground while charging capacitor) 9. Add a current meter on the outside, which will trip if continuous current is above a threshold for a certain time for the entire piano to ensure it won't short 10. Add a GFCI -- im not sure how this handles sparking devices? 11. Put the capacitors/resistor circuit away from the strings/hammers and add a few PC case fans to help keep the circuit cool. Then it should be pretty safe, all things considered (assuming you have ear+eye protection).
Piano idea: I always wanted to see Vibrato to be integrated into a piano, like some kind of lever on the side that could shake the strings a bit, but I understand how this could be too difficult to integrate. Great Video as always👍
A true string vibrato would be hard to implement. But a vibraphone like tremolo/vibrato would be possible, you just need a plate with periodic holes in it, that moves behind the strings. Would be kinda cool!
@@bliz85 yeah, I've suggested a "hurdy gurdy piano" a couple of times, with bow wheels and small electric motors that gets triggered when piano keys are pressed and closes the circuits
I am pretty sure there’s been some really weird attempts on this before on piano. But I’d have to do some digging to find it. But no attempt has been succesfull really. Thank you btw!
Once again amazingly done! Bad Piano Idea: Cowbells or Bottles instead of strings or airtight piano filled with various gasses(like helium) to maybe change the sound. Also you could use this piano to make a pretty cool music video (maybe similar in style to this one ua-cam.com/video/J3cg4tFLm7A/v-deo.html just with less light so you can see the sparks). Or you could try having two people play it at the same time with one person trying to be the "drums" and the other person trying to play a melody. Edit: also looking forward to the next video and pianos/guitars ya legend.
I actually recorded with pro pianist last weekend! And thanks for the ideas. I am very intruiged by making a vacuum chamber piano plus different gasses!
When you said you got an electrician my first thought was should have got an electronics technician, the engineer was close enough. Kind of cool seeing their differing responses. Having an associate degree in electronics, seeing the electrician's response/interaction was very humorous.
Thanks for the Video, i find it nice that they not only came for this time bomb, but also gave good advice in handling that complete disregard to anything you learn about when the words "safety" And "electrical" come together...
I'm surprised at the fellow wearing voltage gloves without the overglove. It didn't seem like he had the glove liners either. That's a pretty good way to end up with voltage safety equipment just as questionable as this piano.
I still think you can Isolate the strings from the electrical loop by running a conductive probe above the hammer head and running a single wire above the strings. This way the spark happens higher up and not actually on the strings. It would save you on materials because you would only have one string that is getting worn and it would be easier to keep the piano in tune. You could technically move the “spark” completely out of the interior of the piano and into a more insulated plexiglass area above the piano to improve safety and make the sparks more visible
To prevent the resistors from overheating when a hammer sticks, a PTC resettable fuse in series with each resistor would drop the current automatically. To reduce the tendency to stick, a 2 watt carbon resistor in series with each hammer would limit the current - you would have to experiment to find the optimal ohm value to choose between spark size and not sticking. Just do 1 hammer first - Start with 100 ohms, go up or down by a factor of 2 each step, depending on the results.
I don't know if this is actually doable, but hear me out: guitar strings + guitar picks hammers piano. For a better effect, you would need to introduce some lateral movement in the piano hammers and shorten their travel distance.
Hi, I have some ideas of what you could do with a piano: "A generator piano" that would produce electricity when you're playing it. It could be made with magnet attached on the hammer that would past through a bobine. A second idea would be: "a xylophone piano" You could replace the strings by a xylophone, that could be nice too! I love your video's by the way 🤩 Always entertaining for a musician and scientist like me😆
I‘d like the idea of a infinite sustain piano, with magnetic coils (or reverse guitar pickups) instead of hammers. basically like a sustaniac or e-bow vibrating the piano strings. (That would also make a nice samplepack)
Best advice I can give is to get a high voltage transformer and greatly reduce the wattage. So hi volt low current. That would be the safest way to go about it. The hi voltage would keep the Sparks, but greatly reduce the risk of death as long as you keep the current in the micro amps. Something like 1,000 volts at .005 micro amps. You could touch it and not get seriously hurt. Wouldn't feel good though 😉
Another great video, can't wait for the next. And maybe for a future piano, build one from actual scrap. I hope that will be less expensive in terms of money. Anyway, great work. Love your videos
I know I won't be the only one doing this but it's worth it anyways Established titles the sponsor of this video was found out to be a scam. You don't own the land, you can't use the Lord/lady title and theres no proof they even plant the trees they say they plant. There also owned by the same owner as another scam company kamikoto knives
For anyone that sees this, buying land from established titles does as much as just legally changing your name to Lord. You do not gain any title of any sort as it is a chinese company selling land in such small quantities that it is unregisterable, meaning you actually do not own any land and therefore do not receive any real title.
Have you ever thought of making a resonator piano, similar to a resonator guitar? Never seen anything like it, but could give an interesting sound.Banjo concept could also be interesting...
Established titles are selling land they don't own. They tricked a lot of people. It's the same thing as buying a star. No one has rights to a star and established titles don't have rights to the land they're selling.
Mattias, look into nomex paper for electrical insulation. Works well into the 1000s of volts depending on the thickness. Would work well for your arc piano for sure. Not the cheapest stuff however. For wire insulation look at buying silicone insulated wire used in RC vehicles. The insulation can withstand higher heat therefore higher currents. It also has more wire strands that make it more flexible. About the only way I can think to discharge the caps is to have a relay or switch that shorts that caps to ground through a high wattage resistor when you power down to bleed them out. Personally I like your arc piano more, but it is also a lot scarier.
I actually been discussing this idea with my engineer friend. But If I can’t get michael reaves on at least a zoom call for that it would feel like a failure! But shouldn’t be that hard to do in theory

"And the resistor... Yeah it turns into like a lamp"
Love that line
I was hoping he was going to follow up with ”when it glows you know it’s on!” comment
Mattias and first electrician:It's like chaotic bros trying to to fix garage made nuke 😂😂
Great description that’s how it felt😂
As soon as the electrical engineer started playing the piano I could see how excited he was by it, he was confused at first but you can tell he really enjoyed the concept and wanted to experiment with it
There are a few ways to make this much safer. Add an isolation transformer before the rectifier (or back to back transformers to step down / step up - you can also adjust your output voltage this way too). Possibly a cheap ZVS circuit module could generate the high voltage from batteries and feed each capacitor via a resistor to the main bus - this removes the mains completely and makes the piano portable.
Add a suitable input fuse (won’t cater for most shorts here but still worth having).
Use bleed resistors on each capacitor.
Use a glass panel or plastic panel which blocks UV (not sure how significant the UV component is compared to say a welding arc).

I was thinking it needed some plexiglass. I'm glad you installed some. I think the concept would look awesome at a concert with the right design and implementation.
You will love next video!🙏
@@Mattiaskrantz YOUR PLAYinG IT AT A CoNceRT?
Electrician with industrial controls experience here.
Have some ways you could make this much better / safer, however you'd basically have to start the build over to implement some of these ideas.
1) using the bare metal of electrified hammers and your piano strings in order to directly run the power circuit is actually, properly insane.
It would be a far better solution to mount a small bracket that holds your conductor on the side / top / etc of your hammers which would make a connection with a 2nd bracket to the side of / behind the piano strings at the same time as the hammer lands. Using pieces of flexible metal that can slide up against eachother as the hammer moves forward / backward would be ideal, and these two changes would help keep your piano's sound much more normal and eliminate wear.
It's also worth noting that the far more obvious (but admittedly far less fun) solution to this would have been just putting a low-pressure push button below each of your piano keys that completes the circuit when you hit the key. But again, way less fun.
2) Relays fired with low voltage.
Right now it seems like you're running your circuit's load directly through the circuit connection. This is bad for *many* reasons.
What you could do is have a power supply that produces a low voltage like 12v hooked up inside your piano which would be used for separate, "controls" circuitry.
This 12v is what you would actually be running through the wires on your piano hammers. From there, the completed circuit would fire the coil of a relay which would then separately connect the higher voltage power to the capacitor in a MUCH safer manner. This plan would also massively reduce or eliminate the electrical arcs thrown around near (or at) your fragile piano strings due to the load drawn by a single relay being essentially nil and the 12v being far less dangerous / air-arc-ey in general.
3) install plexi-glass tubes over each of your individual capacitors.
This will help contain the sparks thrown by the capacitors, limiting the amount of fires you start inside your piano. This would also make it way more visible which note is being played as it'll only light up a single pillar above the capacitor rather than "exploding" out everywhere. Hypothetically speaking, you could even run them out the top of your cover like an organ and thus be able to play the piano with all your exposed electrical parts safe from being touched.
I doubt you wanna mess with this project anymore than you already have but I'm happy to answer questions about this or generally discuss it with you or others here =)
Some random piano ideas:
- A piano that plays like another type of instrument, such as wind or percussion. (Like the guitar video)
- Rube-Goldberg style piano to play each note
- A piano that fires nerf dart/pellets either at the strings or they keys
- A really tiny, but functional piano
- A piano that can be controlled via computer and can play itself (I think you may already have this?) - would be cool to connect it to one of those floor pianos you play by jumping on/with your feet
- Gaming piano with haptic feedback (such as the stool and keys vibrating - plus lots of RGB)
- Just a really loud piano
Some kind of projectile piano would be amazing. But also the other ideas are good🙏🫡
You should do a piano that is on remote control, so it can actually chase the service people around when they come to fix it.
Actually having a live show with this piano would be amazing, defiantly looking forward to it if it happens.
I had a pro pianist play it!
I just cackled when that was mentioned because if there's anyone who would actually do this live, it'd be Flake from Rammstein I could see making some sort of contraption for his synth to control a Tesla coil on top of the insanity of their pyrotechnics.
"It's kinda grounded" is honestly terrifying.
Mattias: builds a piano that has a fair chance of catching on fire or electrocuting you.
also Mattias: censors the word "shoot"
I've been watching (and enjoying) your content since the first one of your piano experiments came out and I would just like to say, you never fail to entertain.
Every one of your videos is amazing and and I admire your creativity and problem solving skill. As a musician who wants to study engineering, you are such an inspiration.
Thank you so much Justin🙏 Truly appreciate you have not given up on my weird vids🤝
I love how this just devolved into two children screwing around. Like seeing how much resistance you have XD
It kind of had a purpose; I was wondering how much current would go through your body if you touched it
@@windyr The jump cuts made it seem like you went from "horror" to "fascination" over the piano, straight into "this is stupid let's just screw around"
i stan this cute relationship you two have its freaking adorable
Hahahh yes he was very fun!
here's a piano idea: make a piano that, when you push a key, compresses a mini bellow which blows air through the corresponding note on a harmonica.
You would probably need chromatic harmonica to get the notes you need, and then it's only 4 octaves, so you would probably have to only use the 48 middle keys on the piano.
Wait isn’t this exactly how a reed organ works? I recall watching some restorarion videos on these things and this felt familiar!
@@Mattiaskrantz Yeah actually it is pretty similar, although in the case of organs, there's usually one set of bellows (electric or pedal powered) which blows the air through the reeds depending on which key valves are open. I always thought it would be interesting if there was an instrument where pressing on the keys actually provided the air pressure instead haha
Good idea, but a little too late. The pump organ was invented some 250 years ago.
So a few things to make it safe:
1. DECREASE the wire gauge -- just to be safe (14awg should be fine)
2. Tied ALL of the capacitors to a common neutral, and then add a SWITCH to "turn off" the sparks, which discharges the capacitors through a high current resistor -- and add a voltmeter to this neutral.
3. ADD a grommet to the cord coming in (and relocate near the bottom of the piano)
4. INSULATE the PCB onto a thermally safe material
5. Add a series of thermal sensors to check for overheating of the resistors and cut power to that key / group
6. Add an interlock cover OVER the top, where you CANNOT open the top unless you turn off the power (and then it discharges)
7. Add a brush and guide that will apply the necessary paste in an easy manner
8. Add a "timer" to detect if a key gets stuck, which will disable that key/group if the circuit is closed for too long (just disables the circuit to ground while charging capacitor)
9. Add a current meter on the outside, which will trip if continuous current is above a threshold for a certain time for the entire piano to ensure it won't short
10. Add a GFCI -- im not sure how this handles sparking devices?
11. Put the capacitors/resistor circuit away from the strings/hammers and add a few PC case fans to help keep the circuit cool.
Then it should be pretty safe, all things considered (assuming you have ear+eye protection).
aye glad to see you made this video you were talking about :P
Piano idea:
I always wanted to see Vibrato to be integrated into a piano, like some kind of lever on the side that could shake the strings a bit, but I understand how this could be too difficult to integrate.
Great Video as always👍
A true string vibrato would be hard to implement. But a vibraphone like tremolo/vibrato would be possible, you just need a plate with periodic holes in it, that moves behind the strings. Would be kinda cool!
Could be accomplished like a Vibraphone, using resonating tubes with rotating covers
Maybe a piano that bows instead of striking, with a pedal-operated vibrato?
@@bliz85 yeah, I've suggested a "hurdy gurdy piano" a couple of times, with bow wheels and small electric motors that gets triggered when piano keys are pressed and closes the circuits
I am pretty sure there’s been some really weird attempts on this before on piano. But I’d have to do some digging to find it. But no attempt has been succesfull really. Thank you btw!
Once again amazingly done!
Bad Piano Idea: Cowbells or Bottles instead of strings or airtight piano filled with various gasses(like helium) to maybe change the sound.
Also you could use this piano to make a pretty cool music video (maybe similar in style to this one ua-cam.com/video/J3cg4tFLm7A/v-deo.html just with less light so you can see the sparks).
Or you could try having two people play it at the same time with one person trying to be the "drums" and the other person trying to play a melody.
Edit: also looking forward to the next video and pianos/guitars ya legend.
I actually recorded with pro pianist last weekend! And thanks for the ideas. I am very intruiged by making a vacuum chamber piano plus different gasses!
@@Mattiaskrantz That sounds actually impossible lol. Good luck if you decide to attempt it.
Mattias, with the electrician you are a duo of pure comedic gold. Please invite him more! :D
When you said you got an electrician my first thought was should have got an electronics technician, the engineer was close enough.
Kind of cool seeing their differing responses.
Having an associate degree in electronics, seeing the electrician's response/interaction was very humorous.
Thanks for the Video, i find it nice that they not only came for this time bomb, but also gave good advice in handling that complete disregard to anything you learn about when the words "safety" And "electrical" come together...
''You just ape-brained it into the side'' What a quote lol.
very unique electric piano, mattias. hope the electricians can offer solutions to fix the piano.
I’m not sure if they did hahah. Kind of?😆
@@Mattiaskrantz i'm sure their reaction to your electric piano was worth it though.
@@lastnamefirstname8655 ofc I actually didn’t even have time to implement anything before I had the pro pianist playing it
@@Mattiaskrantz can't wait to see the pro pianist play your electric piano!
The electrician backing into the corner of the room tells you everything you need to know
Honestly, imagine playing Blinding Lights on this piano.
That would be the obvious choice if he collabed with Styropyro instead of ElectroBOOM.
*_LASER PIANO!!!_*
Now we're waiting for you to call a plumber to fix the piano that is filled with water.
I'm surprised at the fellow wearing voltage gloves without the overglove. It didn't seem like he had the glove liners either. That's a pretty good way to end up with voltage safety equipment just as questionable as this piano.
I still think you can Isolate the strings from the electrical loop by running a conductive probe above the hammer head and running a single wire above the strings. This way the spark happens higher up and not actually on the strings. It would save you on materials because you would only have one string that is getting worn and it would be easier to keep the piano in tune. You could technically move the “spark” completely out of the interior of the piano and into a more insulated plexiglass area above the piano to improve safety and make the sparks more visible
This was definitely fun. I'm glad they were shocked, but not shocked.⚡😵💫
Thank you! Me too😁
To prevent the resistors from overheating when a hammer sticks, a PTC resettable fuse in series with each resistor would drop the current automatically. To reduce the tendency to stick, a 2 watt carbon resistor in series with each hammer would limit the current - you would have to experiment to find the optimal ohm value to choose between spark size and not sticking. Just do 1 hammer first - Start with 100 ohms, go up or down by a factor of 2 each step, depending on the results.
I don't know if this is actually doable, but hear me out: guitar strings + guitar picks hammers piano. For a better effect, you would need to introduce some lateral movement in the piano hammers and shorten their travel distance.
Hi,
I have some ideas of what you could do with a piano: "A generator piano" that would produce electricity when you're playing it. It could be made with magnet attached on the hammer that would past through a bobine.
A second idea would be: "a xylophone piano" You could replace the strings by a xylophone, that could be nice too!
I love your video's by the way 🤩 Always entertaining for a musician and scientist like me😆
It could also maybe be made with a piezoelectric thing, like you have in the click lighter's.
That is some really interesting ideas. I’ll think a bit more about these thank you!😄🫡
Xylophone pianos exist, I actually have a really tiny 2-octive piano for toddlers that's essentially a xylophone.
You may want to do research about the controversy around your sponsor. Besides that I loved the video and am a faithful subscriber🙂
I‘d like the idea of a infinite sustain piano, with magnetic coils (or reverse guitar pickups) instead of hammers. basically like a sustaniac or e-bow vibrating the piano strings. (That would also make a nice samplepack)
This actually exist. I would link it if I would recall it’s name. Sounded really cool!
Absolutely love the first electrician keeping WELL away from the piano after the initial look :D
This video perfectly demonstrates the difference between a mechanic (electrician) and an engineer.
Best advice I can give is to get a high voltage transformer and greatly reduce the wattage. So hi volt low current. That would be the safest way to go about it. The hi voltage would keep the Sparks, but greatly reduce the risk of death as long as you keep the current in the micro amps. Something like 1,000 volts at .005 micro amps. You could touch it and not get seriously hurt. Wouldn't feel good though 😉
Another great video, can't wait for the next.
And maybe for a future piano, build one from actual scrap. I hope that will be less expensive in terms of money.
Anyway, great work. Love your videos
Thank you Mike! If I know pianos, that would end up super expensive somehow😁
Might wanna reconsider the sponsorship on this video, bud. Other than that, I like the piano.
"Can you watch it so it doesn't weld?"
"What??"
Most genuine thing I've seen today
haha I couldn't hear anything
I know I won't be the only one doing this but it's worth it anyways
Established titles the sponsor of this video was found out to be a scam. You don't own the land, you can't use the Lord/lady title and theres no proof they even plant the trees they say they plant. There also owned by the same owner as another scam company kamikoto knives
Hey, FYI.. The Scottish custom DON‘T officially call you Lord or Lady. Please reconsider your statement

For anyone that sees this, buying land from established titles does as much as just legally changing your name to Lord. You do not gain any title of any sort as it is a chinese company selling land in such small quantities that it is unregisterable, meaning you actually do not own any land and therefore do not receive any real title.
this guy just came and you immediately became a comedy duo
I'm absolutely dead. That has to be one of the funniest things I've ever heard. "You just ape-brained it right into the side".
Keep up the good work 👍 You might want to take a closer look into Established Titles, they do not have a good track record.
Have you ever thought of making a resonator piano, similar to a resonator guitar? Never seen anything like it, but could give an interesting sound.Banjo concept could also be interesting...
I’ve not exactly that. I recall some piano tech wanted me to exchange the soundboard to a steel plate to get som plate reverb😆 But that’s the closest
Established titles are selling land they don't own. They tricked a lot of people. It's the same thing as buying a star. No one has rights to a star and established titles don't have rights to the land they're selling.
They never claim to let you use the land, all that they claim is you can get Lord or lady before your name.
@@southafricancarlover8666Yeah but even that is a lie
...They were absolutely gobsmacked and will never forget they came over.
Really fun that you had both an electrician and an engineer.
Thank you! I thought people would like it🫡
Nothing better than waking up to this, thanks for the amount of effort you put into your videos!
Thanks for waking up to this chaos!🙏
@@Mattiaskrantz Beautiful chaos!💯
i kind of want to hear through the fire and flames on this piano

Itd be sick to make a piano that tracks what notes you play and tries to use some sort of ai to play with you.
One would get depressed because of AI playing better lol
Madness. Exact type of madness that gets you killed... and recommended on youtube
Mattias, look into nomex paper for electrical insulation. Works well into the 1000s of volts depending on the thickness. Would work well for your arc piano for sure. Not the cheapest stuff however. For wire insulation look at buying silicone insulated wire used in RC vehicles. The insulation can withstand higher heat therefore higher currents. It also has more wire strands that make it more flexible. About the only way I can think to discharge the caps is to have a relay or switch that shorts that caps to ground through a high wattage resistor when you power down to bleed them out. Personally I like your arc piano more, but it is also a lot scarier.
A piano that shocks you if you play the wrong note
I actually been discussing this idea with my engineer friend. But If I can’t get michael reaves on at least a zoom call for that it would feel like a failure! But shouldn’t be that hard to do in theory
This reminds me of the bone organ from The Goonies. Although that result is worse than shocking ultimately.
What if you had custom piano strings made of different metals. This would be cool because some metals spark different colors.
I did look into this but didn’t have enough time before the pro pianist was going to play it!
@@Mattiaskrantz or maybe easier and less costly could be to coat the hammer head with a metal
@@Mattiaskrantz Someday I hope to see this creation fully perfected as an all out custom design honestly. It's so exciting to watch!
