WebIOPi – Browser based GPIO for the Raspberry Pi

WebIOPi is a webserver and a combination of libraries to control the Pis GPIO from the browser or from any application via HTTP/REST. It also has support for many common ICs like I2C IO expander etc.

The feature list:

  • Control, debug, and use your Pi’s GPIO, sensors and converters from a web browser or any app
  • WebIOPi is the perfect Swiss-knife to make connected things
  • Written in Python, with facilities to load and execute custom script, using a comprehensive structure with setup and loop functions
  • Unified Serial/SPI/I2C support with a complete and consistent set of functions to control more than 30 devices, including most used analog converters, I/O expander and sensors
  • Javascript/HTML client library to make Web UI
  • Python/Java clients, to make Pi-to-Pi systems or Android applications
  • CoAP support brings the best Internet of Things protocol on the Pi, as a future proof of Pi possibilities
  • Includes simple web apps, to debug GPIO, devices and Serial interface


Infinite Jukebox – Sound Loop Generator

A Music Hack Day event in Boston has yielded a funny little web app The Infinite Jukebox creates an infinitely long and ever-changing version of uploaded tracks and visualizes the process.

It also shows how todays chart music material is copy an pasted together in the studio as it performs really well on such material meaning you can’t really hear the cuts. On older tracks, were larger portions of the song are recorded in one take, it doesn’t work that well.

If you want to test. At the moment it only seems to work with Chrome and Safari not with Firefox.

Building a live Google Earth

Two high definition cameras fixed to the International Space Station will soon offer real time pictures from space to everyone.

That promise is made by the Canadian startup UrtheCast . According to the BBC they will launch two high resolution video cameras to the International Space Station ISS on board a Russian Proton supply ship early next year. Cosmonauts are already in training to manoeuvre the bulky equipment from the capsule into the station and for the space walk necessary to install the cameras on the outside structure.

The cameras will offer a resolution of about 1m per pixel. According to UrtheCast you won’t quite see the tiles but all the detail in your garden.

The basic service on offer will be free – with users able to log into the site and see live or archived images and video of anywhere on Earth. With the ISS orbiting the planet around 15 times a day, sooner or later it’ll be above something you want to look at.

UrtheCast plans to give software developers free access to its code, allowing them to develop new applications such as games or utilities.
