How to use a stylus with your XO

A team sponsored by Uruguay’s Universidad de la Republica has developed a simple electronics kit that can be used to modify an XO-1 to let you draw on its screen with a wireless stylus and a thin acrylic sheet, turning it into a touchscreen.  Christoph has written more about this and their related robotics work.

The methodology described in their project poster is brief and tantalizing – it looks like a most promising idea. The invention can in theory work with any screen or computer, but here they are showing how it works with an XO. Here is a closeup of a Lapix set in action:

butiábot: XO Linerider robot in action

Team BUTIÁ from Uruguay has been working on an XO robotics project for over a year. They showed off their line-following XO-robot, butiabot, in Montevideo this weekend. An XO running TurtleArt code hooked up to a mobile robotic platform followed a dark line along the ground.

They have posted some details of their prototypes online.
This reminds me of the XO hack to control a Roomba over the Net, but cooler, with Turtle Art and a realtime-hackable control program.

Localizing your XO keyboard

Another quick post in our series on home-brew XO customizations — Bob Chao of CC Taiwan fame shows you how to localize an XO keyboard into Chinese with stickers!   Currently in Chinese; I’ve asked him for an English translation for everyone else who wants to run a little keyboard-customization shop (currently I’ve heard strong requests for German, [extra] Arabic, and Hebrew).

Thanks for the trailblazing, Bob.  If you have a cool hardware hack to show off, leave a comment here or drop me a line!
