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 and watch a video below:
Adventure Time BMO
NinjaBunny9000 has created a life-sized replica of BMO from Adventure Time. The case is 3D printed and the buttons on the front are routed via the innards of a generic SNES controller. The battery can last for around 24 hours and he has added a wireless games controller as well for the full range of controls. The software side is RetroPie and is displayed on an 8-inch screen. You can see more photos of the build on his Imgur page.
Smart Alarm Clock
Here’s a nice 3D printable project for you. fgebhart has used a Raspberry Pi Zero, some prototyping board, an alphanumeric display, an amplifier and a 3D-printed enclosure to build a smart alarm clock.
It has the following features:
- text to speech synthesizer
- three ways of wake-up sound:
- play local mp3 files
- play internet radio station and
- play latest news as podcast (independent to the alarm time)
- set alarm via smartphone or any other computer
- runs Apache2 server
- automatic display brightness adjustment
- audio amplifier volume control
- 3D-printed case
- built-in tactile switch
- alphanumeric display shows text
- 3W speaker definitely wakes you up!
