Multitouch Prototype 2
11 months ago
8 x 8 touch sensitive array sampled at 1300 Hz. Cost: about $50 in materials plus a nice audio interface. More info: 2uptech.com/intimate_control

looking forward in seeing and hearing more of your work
At 1:26, why doesn't the pickup signal change? Is it because you're looking at column 1, which isn't really depressed at that point?
Some of this could be implemented using an Arduino, to cut down on cost. The excitation signals could definitely be generated using an Arduino. The pickups are the hard part. One way to make a cheap 8-channel input is with 4 Griffin iMics, which comes to $120 (of course, with that you could do the excitation signals too). You could do the most basic signal processing on an Arduino, but you'd have the bigger problem of serial output around 120 Hz... unless you did it over ethernet, which could be cool: two Arduinos and an ethernet output.
I would love to see someone make an Arduino version. I am not sure that it can generate the precise frequencies needed for the carriers. I am working towards a microcontroller-based solution though.
Since the Arduino runs at 16 MHz, any frequencies it generates will not be perfectly in sync with 44.1 kHz, but I think you could probably generate them close enough to what you want.
I'm looking forward to the microcontroller-based solution -- if you can get the analysis off the computer and into the package, I'm totally ready to replace my Trigger Finger with this :)
You can find a thread about your project here: nuigroup.com/forums/viewthread/3884/
Again,
Great job and hope to see you at NUI Group
The only downer is completely occupying an 8 in/8 out audio interface. But as a concept - cool indeed. Now figure out a way to implement visual feedback on the pad! :-)
Would it be feasible for someone to incorporate an led grid into a similar device while preserving its current functionality? I realise that this might be 'thinking small' in terms of the possibilities this presents, but i think that many would be excited about the prospect of a pressure sensitive monome ;)
I would love to see this hardware being used to simulate a Hang Drum.

Hang Drums are really expensive but I would love to play one, and I am sure that I am not the only one.
keep up stunning work!
let`s increase the project
it `s amazing
