Project: Easy Arduino Laser Tripwire Security System via Instructables

A great little learning project to use some of the components that might have come as part of your sensor starter pack.

I wonder if you need the specific laser light detector or could use a photoresistor or phototransistor on the detecting end of the system, especially since my set didn't come with the former.

Google Docs adds templates

I have started to move away from using Microsoft Office (Word, Excel, Powerpoint, etc) in favor of online tools like Google Docs . Even as a computer consultant, I find that I use probably less than 10% of the features in any of these projects.
