Weekly roundup 9/24/11

In case you missed them, here are the most popular posts from this past week.

Our most popular post is about a hand-made security robot that any good hacker would be proud of. This robot was built by a father-daughter team and has an interesting holonomic drive train that allows it to drive in any direction at any time.

Our next most popular post was about eight breadboard hacks that let you do more with your breadboard than you previously thought possible.

Following that is a post dealing with what you can do with a dead laptop battery. Surprisingly, not all of the cells are dead so there is still useful life in some of them.

Next we have a post about an electronic cello that uses a combination of a magnetic pickup for the bow and resistive strips for the strings. There is even a video of it being played.

Finally, for those of you looking to grow things indoors throughout the year, we have a post about a hydroponic setup.
