Human interaction is important with user interfaces but it’s also important in other areas. Feeling that the actions you take have a real effect is very important. This is very true of musical instruments, the last thing you want from a musical instrument is something like a kazoo which is so far away from producing actual music.
Enter the Posc, this device, invented by a friend of mine is genius. Using a couple of pins to measure skin resistance and a light dependent resistor the oscillations created by the timer ICs are modified. The device is like something built specifically for the purposes of circuit bending, when playing with it you feel how the slightest movement of your fingers over the light sensor and how your fingers moving across the pins change the sound. It truly is a human experience, I love it, so simple to build and so easy to play.
I was lucky enough to get one of the kits for the device from Jim and Kat last night and I assembled it in less than half an hour. Rather than showing you my awful soldering skills I’ve included an image of the kit instead.
The other great thing about posc is that it’s all Creative Commons and LGPL which means the idea can spread wildly, just like GNOME You can build one of these devices yourself using the circuit diagrams and tutorials the PCB artwork is even available for those of you who like to etch. Alternatively, you can purchase the kit, including all of the parts you need directly from the sonodrome shop or the makers market.
