So I was very busy for the holidays and barely checked my email.  After the first of the year, I started to play catchup, and lo and behold, I had an email from Leap, makers of a new interactive motion controller the size of a soap bar.

I signed up as a developer for this device over a year ago, and here it is!  So they sent an email saying as soon as i confirm my address, I get a free developer unit and access to the developer forums and SDK.  I can’t wait to try it out…maybe I’ll mount it to a robot and use it as a vision sensor!

Solar Tracker made from $5 discount robot

I found this cheap robot toy at Walgreens one day for $5.  I bought it because I can’t resist crap.  Especially cheap crap.  And i liek robots, so whatever.  It is a simple remote control toy, but I soon discovered it had a nice drive train and gear system.  Actually a perfect system for using in a mini solar tracker.  It turns horizontal motor rotation into vertical rotation.  Perfect for mounting a solar panel and sun sensor!

The solar tracker circuit is taken almost directly from the below websites.
