this is probably gonna shock you because it's an electric piano that's like really
electric like all digital keyboards it has a computer that recognizes which keys are being
pressed and produces a matching note through a speaker but unlike other digital keyboards
it also knows when you're pressing the wrong key and responds by taping you
oh my God it's a simple concept with major implications but before we examine its inner
workings discuss the complete revolution of the music industry or watch countless people
get electrocuted I have to come clean about something I'm not an engineer I'm a Pianist
pianist I have a degree in music and this may be surprising given how much stuff I've built
but when I hit College a mere three years after YouTube itself came into existence I wanted to
be a film score composer and spent countless hours at the piano improvising screwing around
and occasionally learning some pretty cool stuff along the way I've had some exceptional piano
teachers whose lessons Insight correction and friendship are now obsolete but just how does
it work well if you want to electrocute somebody when they make a mistake on the piano there's a
few ways to go about it for instance people often become nervous when they do something
wrong if we measured metrics such as heart rate skin conductance even how fast their eyes blink
we might be able to ascertain a pianist's correct or incorrect state of being at the piano and then
simply turn on or off a shock to their entire body the problem with this is that you can be nervous
without making a mistake and if we somehow fixed that problem and it only shocked you when you
actually pressed a wrong key you still wouldn't know which wrong key you pressed when I dreamed up
this design years ago I knew that it had to shock you exactly when and where the mistake happened
and that's why this piano is equipped with 96 relays one for every key plus a few to spare
relays are like switches that can be turned on by a computer by wiring every single relay to its own
specific key we can send a shock to the specific finger that made the mistake as soon as it makes
the mistake provided of course we can teach a computer to recognize a mistake and know which
switch to turn on thankfully this is just a matter of some code and I have quite a lot of experience
asking for help difficult tasks are much easier when you have the right help and the right help

clever code of my buddy Eric who has been helping me play with matches since I was a child it's one
of my earliest memories Eric wrote a program that would compare the incoming midi signals
from the keyboard with a list of expected midi signals from a piece of music and if there was a
discrepancy it would activate the relay connected to the incorrect key that was pressed yeah but
he didn't stop there he then found a graphic interface by Simon Rodriguez spiced it with his
existing program and Bam this is incredible we've got a graphic interface now play anything on your
now you can see what you're supposed to play just like those YouTube piano tutorial videos
and here's the kicker you can challenge your friends at least that's what I did with my high
school piano teacher Chris whoa of course I didn't immediately tell him what was going on obviously
this is a control circuitry for something all I want is for you to play what's coming down
nicely done what happened nothing why don't you make a mistake Chris why don't you hit it I don't
want to make a mistake geez that's cruel once he started to catch on he was surprisingly on
board with the idea I'd like to teach you another song The Rules were simple you record a few notes
then you both have to try and play it back and of course every mistake you make you get shocked
he's not gonna make a single mistake this is going to be the most frustrating experience
you almost couldn't figure out your Rhythm at the end there that's because there was no rhythm the
problem with this game is that the longer you play the longer and more nuanced your pieces become
until eventually you are just as likely to shock yourself as the other guy I'm not getting shot
don't I'm literally shaking right now are you sweating a little bit but as Chris and
I emotionally ragdolled between the highest highs and the lowest lows it finally came to
an important realization hey you know what I realized we could play things for Charlie
what you know your way around a keyboard right just no you've been a panel teacher yeah I've
had dozens of students so this is not I've never been a piano teacher so he's more indicative of
the typical user experience yeah you'd be your target so what we've established is that you
can have a good time with your close friends so little Charlie how was your first piano lesson
today shocking but what we really need to find out is what the greater music Community thinks
for instance is this something that you could sell in a music store tool can you
kind of describe it to me a bit it's it's a piano that when you make a mistake it uh it shocks you
and then check it out now the stores might not have been interested but they are really just
a middleman to the music students so we took it to the practice rooms at my old College this space is
forever burned into my memory and apparently my face is forever taped to the wall the piano was
set now we just had to wait for some unsuspecting students if you make a mistake it will electrocute
you oh yeah does it shock you if you press the wrong one yes now some clever students
were able to figure this out on their own because I noticed like all the metal but the keys are not
fully metal it's actually just aluminum and copper tape which only took my brother like 12-ish hours
to apply this is necessary to conduct the high voltage that is generated by the TENS unit which
is a muscle shock therapy thing one electrode wire runs through the relay bank and the other
is attached to both of your wrists when the circuit is completed through an activated
relay you really only feel it in your finger and I assume it's because there are way more nerves
here than in your the tens device is perfect for our use because you can adjust the level
of shock for most people a 3 is more than enough fun but for others limits were meant to be pushed
I think I can I can do more yeah
yeah yeah what one more one more yeah
that's enough yeah even more amazing than her pain tolerance was the overall positive response
we were getting to a piano that shocks you so is this something that you would then want to have
as a tool at your disposal honestly yes this is good because it keeps the people on Tempo
like I'm motivated to play the right notes that even includes teachers that's amazing because
you not only have to hit the right note but you have to rhythmically time it but what stood out
to me the most was that even perfect strangers seem to greatly enjoy causing me pain but how
far could we take this if we set up a table at a venue packed with people like say Comic-Con and
ask them to challenge Me by playing something on a second keyboard would they go easy on me
or would they purposely play something super difficult in the hopes of seeing me get shot I
think this sounds like an incredible way to get information out of somebody yeah okay so Black
Widow wants to hurt people big surprise there and trying to play Anything by Doc Ock will will be
at least like eight times harder than normal but if anyone's got my back it's the cap right
good luck
I think it's a fantastic idea but I'm not entirely sure negative stimuli is the great way to go about
it yeah but you would say that because you're like Captain America and you're all a good
institutions you're right while Steve may have done his darndest to limit my pain a significant
portion of people would play something difficult or just random I don't mind seeing people get shy
and I guess I can't really blame them I mean if you knew that a piano could shock someone you
would probably want to see it shock someone even if the player themselves had already been shocked
like a lot I just realized that I've been shocked hundreds of times and I even cranked up to eight
that one time I would rather get shocked a few hundred more times than get shocked again one
time at that eight this was all good data I felt like I was missing something important my college
piano Professor more importantly my toughest piano teacher Beatriz still hadn't seen it but
after some schedule juggling I finally brought her to my basement and soberly explained the situation
it will shock you oh like a dog by the way this is in no way revenge for the four years of lessons
play it more importantly what would she think what do you want to try yeah sure are you going
to sue me no okay good for this brief moment you get to remember what it feels like to be
a piano student teacher she took to the task with dedication and inevitably got her Taste
of fire can you jump back in yeah no I don't we should try one more time yes one more time I do
but after getting the hang of it I was surprised to hear her say this it has some uses I can see
they use for example when you are teaching intervals yeah but it should be a game you
can see a professor really using it no because they're gonna get sued you know it's a game I
could see students actually taking advantage of these wow it's crazy so what would happen if we
gave shocking piano lessons to other YouTubers can I give you a piano lesson oh my goodness dude
Peter can I give you a piano lesson a lesson yeah I okay sure oh no if you turn down the
shockies comment below who you want to see gets shocked there's already so much that I can't fit
into this video and there were so many amazing people who helped make it happen especially my
buddy Eric I really have had some amazing music instructors and the world would be a much darker
place without music so please take the time to appreciate the music teachers and your life
and thank you for taking the time to watch see you next time
