I augmented my trusty trackball with a scroll-wheel and some programmable buttons

Here’s how I built a little LED display for showing whether I’m busy at work.

Adding a middle mouse button and a scroll wheel to my favorite ambidextrous trackball.

I made an inexpensive device that will turn your tv on automatically, if you’ve already got a way to turn the power off and on, like MicasaVerde or WeMo!

I designed and built an IR shield for the Arduino and some software to make it useful.

Working in a vegetable garden is a pleasant and rewarding experience, except for the ‘work’ part. I tried to remedy the problem.

A web app, some firmware and a python program that makes it easier to view your own and the public’s animations on an LED display
