Raspberry Pi Roundup - a calculator with Pi inside, a Pi-ified Wurlitzer Jukebox and a brain monitor

CalculatorPi

Over on Reddit, ecefour posted about his project in which he’s squeezed a Raspberry Pi Zero W, various other electrical components and a screen inside a Texas Instruments TI-83+ calculator. He’s got it running RetroPie and he’s wired the calculator buttons to the Pi’s GPIO pins to enable him to control games, via a little Adafruit magic. You can read about the build here and see a demo video below:

Wurlitzer

Tijuana Rick’s father-in-law found a 1969 Wurlitzer 3100 Jukebox, for free but without the original 45s. Together, they refurbished the Jukebox and then set about turning it into a media centre. They used an Arduino Mega to read button presses which were then fed to the Raspberry Pi 3 which controlled the musical playback. You can read more about the project here and see it in action below:

Brain!

Adam Pantanowitz and a team from the Wits School of Electrical and Information Engineering in Johannesburg have put the data from a human brain on the Internet for the first time. Using an Emotiv EEG device (pictured), they collect EEG (electroencephalogram) data with a Raspberry Pi and then live stream the data to an API which displays the data on an open website, effectively making this an IoT brain! Currently limited to arm movement, the team hopes eventually (and scarily) to have an input/output stream to the brain. More information can be found on the Wits website and in the video below:
