There are quick hacks, there are weekend projects and then there are years long journeys towards completion. [Boris Vitazek]’s grafofon
falls into the latter category. His creation can best be described as electromechanical sequencer synthesizer with a multiplayer mode.
The storage medium and interface for this sequencer is a thirteen-meter loop of paper that is mounted like a conveyor belt. Music is composed by drawing on the paper or placing objects on it. This is usually done by the audience and the fact that the marker isn’t erased make the result collaborative and incremental.
These ‘scores’ are read by a camera and interpreted by software.This is a very vague description of this device, for a reason: the build went on over six years and both hard- and software went through several revisions in that time. It started as a trigger for MIDI notes and evolved from there.
In his write up [Boris] explains the technical aspects of each iteration. He also tells the stories of the people he met while working on the grafofon and how they influenced the build. If this look into the art world reminds you of your local hackerspace, it is because these worlds aren’t that far apart.

[bd594] likes to make strange objects. This time it’s a robotic glockenspiel and hacked HDD‘s. [bd594] is no stranger to Hackaday either, as we have featured many of his past projects before including the useless candle or recreating the song Funky town from Old Junk.
His latest project is quite exciting. He has incorporated his robotic glockenspiel with a hacked hard drive rhythm section to play audio controlled via a PIC 16F84A microcontroller. The song choice is Axel-F. If you had a cell phone around the early 2000’s you were almost guaranteed to have used this song as a ringtone at some point or another. This is where music is headed these days anyway; the sooner we can replace the likes of Justin Bieber with a robot the better. Or maybe we already have?

[Johan Larsby] built this pretty cool Monome clone. He was starting with a kit to build an Arduinome, but had issues getting his LED matrix to work correctly. After digging around in some old parts and hacking together some custom LED arcade buttons, he ended up with the Moanonme. Be sure to check out the video after the break.
