Circuit bending a toy mini piano

- This is me circuit bending a small toy piano I found. The toy is made by Schylling and is called a "mini piano." Originally this toy only had one sound but I found that it had a few other hidden voices and a demo mode. I also added a 1/4" out, volume control, pitch control and body contacts.
Here is a link to a second video that has more details on where to connect the switches. • Circuit bending a toy ...

My young son has one of these and it glitched and started playing a demo tune.. And we couldn't work out how to do it again. Which made me want to seek out some more info... Your video was great! I'm going to pimp this for him

I'm sure that 0.1w speaker can't handle that pitch changes.
No kidding. Keeps spiking. Could probably forage from an old speaker or headphones for a better one. May need a new power source too.
He might need to replace it...
That's pretty cool. You did a lot with that little thing. There must be a way to get to the drums though.
I love this
Cool project. Thanks for sharing. Man... wish you had recorded this through the line out you put in!
Yeet
Would you mind giving me a little more in depth explanation of the switch you used to enable and disable the pitch bend? I see that it has 3 sets of places you can attach things to. You seemed to attach the resister to one of the outer sets, the middle back into there circuit where the resister originally was, and the other outer set to the potentiometer. Am I understanding that correctly? Thanks in advance for your help.
The switch is a DPDT (double pole double throw) which means it is like two separate switches in one. I removed the pitch resistor from the board and connected those points to the center poles of both sides of the switch. Then I attached the original pitch resistor so that it connected the two side of the switch together. Now the opposite two ends connect to the pot for variable pitch adjustment. So when the switch is in stock mode the pitch signal comes from the board and goes through one side of the switch, then through the original pitch resistor, then back through the other side of the switch and then back to the board. When you switch to pitch adjust mode the signal comes from the board, then through one side of the switch, then to the pot for variable pitch adjustment, then back through the other side of the switch and then back to the board.
By "stock mode" do you mean the switch is flipped to the center? I have one of these switchea and noticed it has three positions: up, down, and center, but since there are only going to be 2 functions (Pitch bend enabled and disabled), would the third position be useless?
No. My switch only has 2 positions. on/on. When up it connect center pole to one end and when down it connects that center pole to the opposite end.
will this still work with an on/off/on switch if i were to attach everything in the same positions?
yes it should work the same when set to either on but will not work when in the center at off.
NOOO I HAVE THAT NO WAY
Your videos are cool!
Does anyone know of a way to circuit bend a toy and make it into some sort of guitar or bass effect pedal?
You can make one with an old tape walkman.
Oh really? Would you know of any videos showing you how?
I used one in a video I did. To be honest in the end it did not effect my sound much but I think with a guitar it would probably do better. The idea is that you feed audio into the tape head connection and then out of the headphone jack to get some distortion when you turn up the volume.
you could do that with a voice changer if you add audio inputs and outputs, It wouldn't be that hard.
Space Cadet Go watch Magpie's channel as well, he makes pedals out of everything that can run a current through it. He even amplified a acoustic Toy piano. Great channel like this one.
Just found this one locally. Time to add some FM and filters to this bad boy :D
Have you ever thought about putting any of your circuit bent keyboards on sale?
Yes most definitely. I’ve sold a few things over the years. I have a website but I just don’t have an actual way to purchase through my site. But if you see something you want I might be willing to sell it. Check out www.siskworks.com and send a message through the contact page and I will respond (I just don’t like posting my email here).
that was awesome!!!! wtg☺
pridias construir un modelo propio basado en esto.. para niños y te hiria muy bien una marca propia.....ya que tiene cosas interesantes..que no tienen los juguetes de niños
Yo Mke, you are a powerful wizzard
Jeffrey Newman haha. Why do you say that?
because i opened one of these toy pianos up today and had great difficulty understanding the board, and then found your video, and you bent this thing far beyond i think anyone would ever attempt. and did it well. far beyond where i was planning to go, contact points , brilliant. I am new at bends, but so far you have inspired me the most.
Jeffrey Newman oh cool. Also check out the part 2 to this video where I show in better detail exactly where each wire is connected.
How do you learn to do this?
simple answer is a lot of google searches ;-)
Bloody brilliant! And what do you do when you want to be more "productive"? Got a few things around the house that need attention. Maybe you can help? : )
this is actually a very common board i have found many a toy piano with this board
I'm wondering if that same PCB/blob chip was used in a more exoensive model that had the demo songs and other voices built into it, it just seems to odd that it would have those features but not have controls for them on the keyboard unit's case.
Yes that is exactly the case here. I’ve even seen the “newer” version that has the demo songs available on front panel already
lol just bought one of these thanks for the inspo
Pretty fun to watch. Thank you 🙂
So cool! I want one of those :D
I know nothing about any of this stuff, but want to get into it, and I actually have a piano just like this. Could you, or someone in the video below, please tell me the basic function of testing those demo modes and alternative voices out? Thank you. I don't know anything about electronics. Thanks again!
+M.E. Pritchard Thanks for watching. Did you watch the part 2 video? I detail out where each button and switch connect much better in this second video. Hope this helps. ua-cam.com/video/JUKkCij_EpE/v-deo.html
can i change these tunes?
Hey mike what do you use/ how did you install your body contacts? Great video very informative keep up the good work!
Body contacts connect to the pitch points that the pitch knob is wired to.
can you please tell me where u got piano and parts list?
MONAL SYMPATHETIC I bought this toy new at Cost Plus World Market. But I’ve tried recently to find it again and can’t seem to find it anywhere.
nice
Mike, I am really interested in completing this MOD on my own shylling piano. Would I be able to get detailed instructions from you or/and parts needed to complete this project? Awesome work
+joel revel I also made a part 2 to this video that shows better detail where the buttons connect. ua-cam.com/video/JUKkCij_EpE/v-deo.html
+Mike Sisk Thanks just watched the 2nd vid. I am a beginner at electronic circuit boards, I know i will need momentary switches, but what type of knob is that for the pitch shifter?
+joel revel I think it was a 1 Meg potentiometer but I can't be 100%. It was just what I had on hand at the time so using a different value might work even better for you. I would try a few different values if I were you. Maybe 100K, 500K or 1Meg.
Hey man this is great stuff. I am just getting into circuit bending, and this piano is actually the first thing ive tried messing around with. Heres my first stupid question. Where does the green wire end starting from one of the open contacts? Obviously it leads to one side of the button/switch, but what do you connect the other side of the button/switch to? Thanks for any response! Ill probably fire off a couple more silly questions if that's ok.
To be honest I can't remember. I'll try to make a quick update video that will show the details. I'll try to get that uploaded this weekend.
I would love and greatly appreciate that! Obviously you know what you're doing. I do not.
Sorry I haven't had time yet to sit down and make another video. If you are itching to get started bending yours I would start poking around those open contact near the black blob. Try to connect one of those open contact to another and see how the sound changes. I'll try to make a new vid soon, hopefully this weekend, that will show what combination I used.
FrankMarsala I finally was able to make a video that should explain where I connected the buttons much better. Check it out ua-cam.com/video/JUKkCij_EpE/v-deo.html
Mike Sisk Hey Mike. Thank you so much for taking the time to further explain! It is greatly appreciated. Hopefully I can figure it out and get some cool bends out of this little thing.
I’m in the process of modifying one of these & doing a video. Is it ok if I reference yours ? Thanks
Yes of course. Did you also see that I made a part two? Just shows a few details better is all.
Mike Sisk I had not. Thanks, will definitely check out & reference your video as inspiration.

Do you sell it?
+El Weso would you buy it?
+Mike Sisk Maybe, how much?
how to put this tunes in this toy ?
watch my second video on this toy. Maybe it will help to understand. ua-cam.com/video/JUKkCij_EpE/v-deo.html
What about adding CV input for pitch control...
Wendyn70 yes that could probably be done fairly easy with a LED attached to a LDR.
