ipotti Office Device Lets You Know When to Go
Andy Frey writes in to announce the iPotti, developed using the Make Controller:

So, we have this issue at the office with our single-person bathrooms. We have one “m” bathroom and one “w” bathroom. We have 40+ people in the office. Many people who sit out-of-sight from the bathrooms often walk all the way across our office only to find out that someone else has beaten them to the potti.

To solve this problem, I took a Make Controller from MakingThings.com, wired a couple of Vishay TEMT6000 ambient light sensors (photo transistors) to it, then wrote a Mac desktop app to sit in the status bar to show everyone the status of the pottis. I call it, “iPotti™” and it works awesome!

At the heart of iPotti™ is the Make Controller. It’s an Atmel Sam7 ARM microcontroller with the Make Interface Board stuck to it. The Interface Board has Ethernet, USB, power and breakout headers for the pins of the microcontroller. I wrote a slim little piece of firmware for it that simply broadcasts UDP packets with the status of the pottis. It broadcasts a packet about every couple of seconds.

At the receiving end of the iPotti™ system is a little Mac OS X app designed to sit up in the OS X status bar.
