• How to build a Ti-roBot, a TI calculator robot. I spent a weekend interfacing the TI-83+ calculator to a Motorola 68HC11 to form the Ti-roBot.  I was motivated to do this for my 7th-grade math students.   My students are using the TI-83+ calculator in the classroom and I figured the Ti-roBot will be a useful teaching tool.  The Ti-roBot is pictured in the left photo and uses the base that is described in the article below.  I'll have the article of building the complete Ti-roBot posted soon.
• How to build a simple and inexpensive robot platform for under $30.
• Pat Leang and Vouy Yeng took 2nd place in the UCR IEEE MicroMouse competition with their robot CenterPunch. Click here for more details.
• Revised version of the article "A short introduction to the modes of operation for the Motorola 68HC912B32 evaluation board (68HC912EVB)" is posted. This article describes how to use the modes of operation for HC12EVB to program other HC12s, such as the Kevin Ross HC12 boards.
• Just added a new article titled "Controlling Servo Motors with Various Microcontrollers", an article that I started writing about 1.5 years ago, but never finished. The article isn't quite done yet, but the important information is posted.
• Revised article "An inexpensive infrared line sensor for the MIT Handy Board" and also added an MPG movie of my robot in action using the line sensor.
• Check back later. We'll be adding more content.
