[FIXED!!!] Turn on a lamp with a gesture – Image Processing! Machine learning!

Source: http://makezine.com/projects/raspberry-pi-potter-wand/ Make has a write-up on wand-control with a simple reflective wand… …it *was* broken.  Fixed it. Back in January when I first read the article I was so excited to try it, I ordered a bunch of parts, downloaded the Git, and then figured out it didn’t work. Not to worry though.  A fellow named… Continue reading [FIXED!!!] Turn on a lamp with a gesture – Image Processing! Machine learning!
