Mac controlling hardware
It’s been a while since something caught my attention enough to blog it. This article on Lifehacker, Connect Hobbyist Hardware To Your Mac looks like it could be a cheap but interesting way into using a Mac (or PC) to do computing things with external inputs using a controller board called Arduino.
Projects like the EMI (Experimental Musical Instruments) project

Or any of these examples at the Arduino Playground
This Macworld article also discusses it, explaining how an external sensor will send a signal back via a USB connection to the Mac/PC.
