I got an Arduino Uno for Christmas last year, and of course the first thing I think of is laser pointer turret. I played with this for months while I learned the basics of Arduino programming. It was knocked apart when hail totaled my Trailblazer.

To simplify rebuilding the turret, I bought a pan/tilt kit from trossen robotics. I upgraded the laser from a wal-mart cheapo with the buttons taped. Aixiz lasers are inexpensive and very easy to use. The aluminum mount is taped to the pan tilt kit.

I actually bought my laser parts through eBay

The arduino and radio shack project boards are housed in a plastic bin I bought from wal-mart for a couple bucks. I hung it on the wall with a piece of decorative ribbon swiped from my girlfriend’s wrapping bin. I wanted to see the cats attacking the laser, so I dug out my webcam.

It’s cheap and it shows!

Since I have the webcams mounted sideways, I use willing webcam to rotate the image 90 degrees and display it full screen. I’ve done a left right swap of the laptops for crossviewing. The cameras aren’t fast enough to catch the little cat and the big cat isn’t moving fast enough to be interesting. :-/

Project Requirements
At work we needed a time lapse camera of our new student center construction project. It needs to run continuously for entire length of construction project – approx 18 months. It should run mostly unattended.

It captures 1 picture every 5 minutes. Storage capacity is cheap, so after using excel to make some projections, this worked out to be a reasonable rate for our resources. After some more research, I came to the conclusion that flash video has compatibility with most visitors while being relatively bandwidth efficient, but other codecs could be used. I originally got the idea from but it wasn’t quite awesome enough, so I rewrote using Perl and expanded upon it. Continue reading »
