[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?

If you think of a music box, the first image that might come to mind is that of a small tabletop device with a simple mechanism and a single instrument. Usually a row of chimes triggered by points etched on a roller. If you are a bit more ambitious maybe you thought of a player piano with a roll of perforated paper carrying a tune, but yet again with only the single voice of one instrument.
[Niklas Roy] however has a different vision when it comes to mechanical music. He’s created an entire ensemble with real musical instruments, a drum kit, keyboard, and electric guitar. His Music Construction Machine is no simple music box with a single tune though, it generates a constantly changing melody through a mechanically implemented algorithm with a complex interaction of cyclic variables that periodically alternate between harmonic and discordant. Unfortunately we can’t find any audio examples of the installation at work.
There is a timeliness to this post, the machine is part of an art installation at the Goethe-Institut Pop Up Pavillion on the Nowy Targ square in Wrocław, Poland, and it will be exhibited until the 10th of July. We hope some of our Central European readers will be within range and can make the trip. If you do, we’d love to hear some sample audio from your visit.
We’ve featured [Niklas]’s work many times before here at Hackaday. Just a few highlights are a past musical project powered by water, God on the CB radio, and his all-terrain mobile beer crate.
UPDATE: [Niklas] has posted details of the exhibition in Wroclaw on his blog, including several videos like the on below the break that show the machine in its full glory.

Like many of us, [Laurens] likes video game music and bending hardware to his will. Armed with a Printrbot, a couple of floppy drives, and some old HDDs, he built the Unconventional Instrument Orchestra. This 2015 Hackaday Prize contender takes any MIDI file and plays it on stepper and solenoid-based hardware through a Java program.
A while back, [Laurens] won a Fubarino in our contest by using a MIDI keyboard and an Arduino to control the Minecraft environment with Legend of Zelda: Ocarina of Time songs. The Unconventional Instrument Orchestra uses that Fubarino of victory to control the steppers of two floppy drives. He only needed three pins to control the drives—one to enable, one to set the head’s direction, and one to make it step once per pulse.
If ever you’ve been around a 3D printer, you know they make music as a natural side effect. The problem is getting the printer to obey the rests in a piece of music. In order to do this, [Laurens] used his software to control the printer, essentially withholding the next command until the appropriate time in the song.
The percussive elements of this orchestra are provided by a hard drive beating its head against the wall. Since it’s basically impossible to get an HDD to do this as designed (thankfully), [Laurens] replaced the control board with a single transistor to drive the coil that moves the head.
[Laurens] has made several videos of the orchestra in concert, which are a joy all their own. Most of the visual real estate of each video is taken up with a real-time visualization of the music produced by the software. There’s still plenty of room to show the orchestra itself, song-specific gameplay, and a textual commentary crawl in 16-segment displays. Check out the playlist we’ve embedded after the break.
