A raspberry pi robot arm I built. Is controlled by a bluetooth ps3 controller with pressure-sensitive control. Can rotate infinitely without wires being twisted because all of the components are rotating as one. This was a very fun project to build, and I hope I can expand upon it later. Video:

I started a new youtube channel with the idea of posting videos with pictures of 10 famous places or buildings, and whoever comments with all 10 correct answers will win a spot on my new channel’s “winner’s section”. Link to the channel: http://www.youtube.com/NameThatPlaceGame
Also, here is one of the videos from my new channel:
I would really appreciate if you would go check it out, and please like and subscribe!
EDIT 6/18/13: The Weather Channel is considering featuring this video, keep an eye out for it.
After my previous time lapse attempt, I decided to try one showing the tide coming in destroying a sand castle. I set it on ten second intervals for the photos, this gave it more photos per time and thus showing more of what happened. Video:
I am growing tired of the general weakness of the portal hubs I have been using in my trial trucks. I could, of course, use unimog portal hubs or reinforced portal hubs, but they are too bulky and take away ground clearance. So, I made my own 2-stud wide portal hubs that are very strong, first in Ldraw, then I built them for real. I made two variations of them; one has the steering pivots closer together (standard) and another has them farther apart. These hubs are much more strong and also easier on the u-join because they are more rigid.
