Casio PT-100 Deconstructed At Circuit Bending Workshop
Dan Demchuk hosts our continuing series on the art of anti-theory and circuit bending. Circuit Bending is the growingly popular craft of taking apart battery-powered electronics and subverting their original purpose. In this series, Dan and Bill Holland explore how to take circuit bending and apply it to a live music act.
In this segment, Allison Lake shows off her newfound Casio PT-100. This first section with the Casio takes a look at finding the basic time-bends in the device and marking them.
Stay tuned to Gearwire.com for more circuit bending tips with Dan Demchuk.
DAN DEMCHUK: Hi. I'm Dan Demchuk again at the circuit bending workshop. I'm here right now with Allison Lake. She's been a master of bending Casio keyboards. I don’t know how she finds them but she finds some really good ones and then finds the glitches and finds everything.
Right now, she found a PT-100, and you know she just said, "Oh I gotta -- There's no output on there." We'll get it.
ALLISON LAKE: Hi. See, as you can hear, there's a little buzzing sound coming from here and here as you mark that because it's very useful.
DAN DEMCHUK: I got to get you a Sharpie marker. That's really good to do. Once you find points, mark them with a Sharpie.
ALLISON LAKE: Ooh. That's pretty sweet. Got some droning going on here. Ooh, there's a lot. This thing's loaded.
[ALLISON LAKE LOCATING CIRCUIT BENDING POINTS]
A variety of buzzes and drones that I can choose from to add a switch or a potentiometer but most likely a switch. Ooh! Here we go. Where was that? There was a little bit of distortion. Good.
DAN DEMCHUK: It looks like you're just realty tapping those resistors on there. These are the points. It's really cool juggling those.
If you want to find out more, you're always welcome to stop by our circuit bending workshop. I'm Dan Demchuk. This is Allison Lake.
Could these circuit bending
the basics
ok relax, dont need to get
no worries
and the purpose of probing noise points is?
...and if you cut this wire it continues to do nothing usefull...
get a day job.
Power on Casio PT-100
Hi,
I saw your video and was wondering if you could help me. I have the exact same keyboard, I bought it at a second hand store for 5 bucks, but it won't power up. I know that my wallwart is the right power supply (7.5 dc I think). I took it apart to check for loose solder points but I don't really know what else to do. This keyboard hasn't been abused, it looks great, and I'm dying to unlock those cool 80's sounds for some of my music. Any suggestions?
Thanks for your time,
Mike
Batteries?
Batteries?
PT-100
I did try some fresh batteries also.
Thanks,

They also gave no results. It's a shame, I bought this keyboard for 5 bucks too. It's a mission to get power to it.
Thanks,
Mike
I had the same issue. I just
I had the same issue. I just rolled the batteries around and it worked. maybe yours got wet and fried some circuits or something like that?
