Constantine Zlatev, Kostadin Ilov and Velina Ruseva have taken a disabled shotgun and some salvaged industrial components and created a musical instrument. Called The Last Gun, is controlled by a Raspberry Pi and an Arduino and uses compressed air to play different tunes through the barrel of the gun. Determining what is played is done based on a graph of US arms exports from the 1960s to 2010. If the amount of exports rises, the tune becomes more sombre; if the exports fall, a more upbeat tune is played. You can see more pictures on Constantine’s blog here.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
