When you think about singer-songwriters, the name Bob Dylan might come to your mind. You might think about Jeff Buckley, you might think about Hank Williams, Springsteen, David Bowie, or Prince. You’d be wrong. The greatest singer-songwriter of all time is Tiny Tim, the guy who looks like Weird Al traveled in time and did a cameo in Baker-era Doctor Who. Tiny Tim had the voice of an angel, because Mammon and Belial were angels too, I guess. Tiny Tim is also the inspiration behind the current resurgence of the ukulele, the one thing keeping the stringed instrument industry alive today.
Even though Tiny Tim passed in 1996, he would have loved to see this project that brings the ukulele into the late 20th century. It’s a Game Boy, DMG-01, transformed into a playable musical instrument. It’s a functional uke, but it also has electronics to turn this into a chiptune machine.
The first goal of this project was to build a functional ukulele out of a Game Boy case. This was simple enough — the neck was 3D printed, the bridge was screwed in, and the case of the Game Boy was reinforced with some PCB material. So far, this is nothing new; you can get a model for a 3D printed ukulele on Thingiverse.
The second goal of this project was to make this ukulele into a chiptune machine. This means designing a pickup for the strings, and since these are nylon you’re not going to do a magnetic pickup on a ukulele. The first solution was an IR reflectance sensor, which worked but had too high of a power draw. The better solution was a standard flex pressure sensor, which worked well enough. This signal is distorted into a square wave that gives a surprisingly Game Boy-like sound. You can check out the video demo below.

[Chad] has been messing around with emulators on his phone, but as anyone with a smart phone knows, even the most advanced touchscreen controls are terrible. Wanting something that pays tribute to the classic systems he was emulating, he decided to turn a classic old school brick Game Boy into an Android gamepad.
After gutting an old DMG-01, [Chad] set to work turning the D-pad and buttons in the Game Boy into something his Galaxy Nexus could understand. He chose a Bluetooth connection to provide input for his emulators, with the hardware generously donated from a Nintendo Wiimote.
The Game Boy PCB was cut up and a few leads attached to the Wiimote PCB. After modifying the case to include space for the Wiimote and a cell phone mount, [Chad] had a functional game pad, perfect for his adventures in emulation.
You can see [Chad]’s demo of his game pad after the break,

Reader, [klemens], suggested DMG Lib to us when we posted about a similar site. DMG-Lib is an amazing source of information. It’s primary downside is that a great portion of the text is in a language other than English, though in some ways this is a plus. Latin, Italian, German, and many other languages held the position of being the chief scientific language of the world long before English, and this repository holds entire books about mechanisms in those languages. Some of the books range all the way back to the 1500s. The mechanism animations are very good on this site and play smoothly. While it’s a little harder to search than KMODDL due to the language oddities, it’s still an extremely useful and interesting site to add to the hacker’s information toolbox.
