Zero Phone

ZeroPhone

Hackaday blog: There are several open source phones out there these days, but all of them have a downside. Hard to obtain parts, hard to solder, or difficult programming systems abound. [Arsenijs] is looking to change all that with ZeroPhone. ZeroPhone is based upon the popular Raspberry Pi Zero. The $5 price tag of the CPU module means that you can build this entire phone for around $50 USD.

Features:

  • Raspberry Pi Zero in a PCB sandwich
  • No proprietary connectors, hard-to-get parts or chips that are tricky to solder
  • All the specifications for making this phone yourself will be available
  • Python as the main language for developing apps (aiming to add other languages later)
  • UI toolkit making development quicker and easier
  • Numeric keypad, 1.3" 128×64 monochrome OLED screen (with screen header supporting other types of screens)
  • 2G modem for phone functions, can be replaced with a 3G modem
  • WiFi (using an ESP8266), HDMI and audio outputs, a free USB host port
  • GPIO expansion headers for customization
  • RGB LED and vibromotor – for notifications
  • Tons of Pi Zero-related hacks that were discovered along the way, that I'll share with you as the project goes =)

Braille Bricks: Lego letters for literacy and inclusion of blind children

Braille Bricks: A toy building brick can be whatever you imagine it to be, or even something you’ve never imagined. Braille Bricks is an experiment that transforms these bricks into a tool capable of encouraging creativity, helping blind children learn to read and write. It also encourages the inclusion of children with or without visual impairment.

DermalAbyss: Colour changing tattoos that monitor your health

DermalAbyss: Possibilities of Biosensors as a Tattooed Interface

MIT Media Lab researcher Katia Vega: The Dermal Abyss presents a novel approach to biointerfaces in which the body surface is rendered an interactive display. Traditional tattoo inks were replaced with biosensors whose colors change in response to variations in the interstitial fluid. It blends advances in biotechnology with traditional methods in tattoo artistry.

We developed four biosensors, reacting to three biochemical information in body fluid and changes colors: The pH sensor changes between purple and pink, the glucose sensor shifts between blue and brown; the sodium and a second pH sensor fluoresce at a higher intensity under UV light.

Researchers at MIT Media Lab and Harvard Medical School teamed up to create tattoo ink that reacts to your body’s chemistry.

DermalAbyss

Co.Design: Researchers are getting closer to turning the skin into an interface, while designers imagine what these interfaces might look like. Do they come in the form of a tattoo, like Vega suggests, or a temporary tattoo that doubles as a circuit? Do they act like a second skin? Will we use them to control our devices, or to better understand our bodies? Either way, there’s a whole lot more to explore on the surface of our skin.

Evil Mad Scientist: AxiDraw V3

The AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with your favorite fountain pens, permanent markers, and other writing implements to handle an endless variety of applications.

The AxiDraw is an extremely versatile machine, designed to serve a wide variety of everyday and specialized drawing and writing needs. You can use it for almost any task that might normally be carried out with a handheld pen.

While no parts on AxiDraw require regular replacement, this new machine is built with a “screws not glue” design approach throughout, where essentially every part can be replaced by the end user if it should ever become necessary.

The Big Hex Machine

The Big Hex Machine is a giant, yet simple, 16-bit computer designed by staff and students at the University of Bristol to explain how a computer works.

The giant machine, based in the Merchant Venturers School of Engineering, measures over eight square meters. It is built out of over 100 specially designed four-bit circuit boards, which enables students to be taught about fundamental principles of computer architecture from just a few basic components.

Tech Spark: David May (pictured right, above), Professor of Computer Science in the Department of Computer Science (pictured right, above), designed the Big Hex Machine with education in mind. David says, “You cannot understand how a computer works by taking one apart!”

“In our giant machine, all of the structure is clearly visible – as is the movement of information as it executes programs. It demonstrates the principle used in all computers – general-purpose hardware controlled by a stored program.”

NESPi – my Mini NES Classic Raspberry Pi games console

‘Daftmike’: It was inevitable… I have a Raspberry Pi, I have a 3D printer, I’m a huge nerd… At some point I was going to print a case for it in the shape of the old Nintendo Entertainment System.

In the end, this project turned into more of a love-letter to the NES than just printing a case. I learnt a lot of new things about Linux, 3D design, wrote my first Python program and had a blast doing it…
