Science / Invention Fair Wrap-up!

by on Apr.04, 2010, under science fair

Ok, there are a lot of posts regarding the Science / Invention Fair that Robbie participated in, with his very cool “Light Alarm” circuit. I wanted to post one final summary, a guided tour if you will, of all the previous posts. That way it should be easier for all of you readers to pick and choose what you want to learn about the project, and not have to dig through things as much.

First and foremost, you can see a demo and hear an explanation of the project in Robbie’s own words in the YouTube Video appropriately named “Light Alarm Invention Fair Project”. That summarizes things pretty well.

Beyond that, here are the posts about the project, in order, and following that, some pictures. I’ll also try to get the complete schematics uploaded soon too.
