Capacitive Controller Subject description: a project with sonic |
|
|
sonic and I had a great chat + telephone call last night about creating a capacitive sensing controller, probably spherical in shape. Here are some of the highlights of our discussion as well as my fading memory can recall.
approximately spherical in shape
sonic wants flats, so maybe dodecahedron
can experiment with a cube initially (that would be a first for me, approximating a sphere with a cube, lol)
sonic has no 3D printer, I have a very good 3D printer (Ultimaker 2+)
I just now received some electrically conductive filament
can print tesselations or all-in-one or half-spheres (half-shapes)
use Arduino-programmed ESP8266 chip for comm out of sphere, or just use
simple Arduino for starters and transition to WiFi later.
WiFi chip embedded in an electrically conductive device is not exactly smart lol
can use a Feather from Adafruit to get battery management with USB charging.
can also use inductive charging from Adafruit (then no connector at all, just s sealed shape!)
use a Processing program on the Mac/PC/Linux to receive WiFi and send out OSC locally or across the web.
Would be cool to make sensor readings available on the web. Maybe use Adafruit's cloud.
So, we had plenty of ideas and not much resolute thinking. In particular it's going to be challenging to extend the electric field of the sensors to outside the sphere. Anyway, we've got a project on our hands. I want to get something printed and playable by next week's Summer Solstice event.
Les out, praise the Lord! |

Nice one Les. Yeah I think a new kind of tactile controller would be really cool, and I like the kind of playful direction this is going. I'm still a little hazy on what kind of responsiveness we can get from a capactive-based thing. I think it's important that the musician can get a predictable response from the same controller every time, so that different playing techniques could be developed over time without unexpected freaky output.
Is it worth considering other kinds of sensors too? I'd really like the controller to have a kind of elastic response when you press it in places - aftertouch basically. What kind of pressure sensors do midi keyboards use for aftertouch? Would it be possible to print a kind of pressure sensor using your new techniques?
Many questions. Anyhoo back to making veggie burgers... |

Oh, and I re-connected the circuit with the ESP8266 module and the 9DOF module on a breadboard, plus loaded the software that I had put together before. Now next what is needed is to add WiFi communications.

Les program a WiFi chip! |
