I'm investing my time to devices related to experimental music. My first attempt was an Atari Punk Console, that I modified using photoresistors instead of the potentiomenter and my wife Audrey put in a self built mask.
 

After that, I've improved the mask with an heart shaped LED based pattern generator: playing with position of the heart and the speed of the blinking you can get some nice and weird noise sequences.
 
Then I've built two more drones: one consists of a box with an Atari Punk Console and a Michel Waisvisz's CrackleBox. The CrackleBox contacts are shaped as a Tamagotchi Mannaro, a comic character by a friend of mine, writer and illustrator Alberto Corradi (myspace here). There is a post about it on the Create Digital Music blog.
 
The last drone is an Heavy Metal Machine: just take 4 independant square oscillators, send each two into an cmos-exor gate, send the two exors into a third exor. I've added switches to enable each oscillator and gate and LEDs on every input and output of the gates that produce a nice strobo effect.
 

Other drones followed, based on variations of the same circuits.
 

Finally, I've collected and assembled into a modular box all my experimental circuits: CMOS simple sequencers, Weird Sound Generators, Michel Waisvisz's CrackleBox, Vactrol unit, op-amp based filters and integrators, optical controllers and mixers.
 
The Sound Destruction Unit is born!
 

I've used a set of broken and old hard drives to make another experiment. I've connected the pins of the arm coil to the output of a simple square wave oscillator. Repeating this circuit a dozen of times, using different pitches on different hard drives, I've created the noise console named: the hardiscophone.
