If the velostat is a resistive strip how is it not shorting all the way across? isn't like 1 tape folded over itself? why does it only short when you press on it? Is there any material between the fold? any material glued to the outer side or inside or the strip?
This is a long while back, but do you think it'd be possible to introduce a component between the softpot and the board to make the play linear by pitch (exponential by resistance)? Most ribbon controllers on musical instruments are linear by pitch but I'm not sure what processing they have to do to ensure that.
Id be intrested to see the synth curcit reverse engineered, although I can can pretty mutch guess based off of the sound and simple resistive control imput
WOW! An Otamatone teardown!THANK YOU I've been looking for one for ages! I'm making something similar using an arduino. It's good to have confirmation on the internals, kind of figured the softpot was velostat, kind of neat that it works so well honestly. The circuit board looks like it has some sort of switches on it? Are those fixed in place or?
Hi @ArcanaXVI, thanks so much, happy this was informative to you. Regarding your questions, go to 3:20 in the video. There are two 3-position slider switches to control the Off/Volume, as well as the pitch (low/medium/high).
I don't get it. How does pressing on the folded velostat 'short' it? Isn't it already shorted because both folded lengths are touching all the time? Are there some thin plastic strips keeping the two folded layers apart until you press it maybe ? Also, it looks laminated so how do the two sides make contact?
You could probably make it with like graphite powder on two strips, or maybe even two pieces of foil. Basically any two things with a decent resistance, but are still conductive.
POV: You’re the first otamatone to fall asleep first at a sleepover (The worst mistake ever possible)
Lmao

I can't open my own T.T and I can't follow the steps, because the Otamatone Deluxe is built differently D:
Nice. Thanks for the explanation.
I need to replace the board for my potentiometer. My otamatone has the forever scream. He cries for deliverance but it is not his time yet.
Great video. was trying to figure out what the soft potentiometer was called..Thanks guys, got my answer quickly and learned more!
I have an Otamatone Deluxe and I need help with getting to the spring in it's mouth so I can replace or smooth it out so it doesn't squeak
Do you know what part of the Otamatone may be broken if there is no sound coming out? Mine just died :(
Papyrus 09 get new batteries
@@DeductedSpy lol
I will otam your tone

Can you do the Deluxe next time.
What size screw is for the battery door?
Mine broke and I need a replacement but cant find which one
oooh. Sorry to hear that. Unfortunately, we didn't capture the size of them. :/ Good luck.
Tomorrow Lab can you do the Deluxe next!
Thanks so much for the intel, guys.

@@TomorrowLab Ohhhh of course! Got so excited about seeing inside this thing that I forgot it has some means of control. Thanks again, guys. :)
Tomorrow Lab can You do the deluxe Now!
an arduino is a bit overkill
you could use a 555 or even a single transistor oscillator

Fuck finally thanks guys, this is a hard to find tear down. Vel-o-stat haha, love it.
does any1 know how to make that variable resistance?
You could probably make it with like graphite powder on two strips, or maybe even two pieces of foil. Basically any two things with a decent resistance, but are still conductive.
ESD safe bags (the silvery ones) are some nice stuff to use for that.
The poor otamatone😢
It can be made inti a portable. Talk box
cant unscrew it no matter what
