In case you have been on vacation, here is the best that we have had on our blog in the past week:
In first place is a post about [the University of Pennsylvania’s] quadcopter team. This time they have a group of twenty quadcopters flying in formation.
In second place is a post about a nice project by [Joel] where he converted an overhead projector into a TV projector by projecting through a LCD TV. He went all-out on this one by using a CNC machine to cut out a special holder for the LCD and the fans necessary to cool it.
Next up we have a post about a project where a 55 gallon plastic barrel is turned into a wind turbine. We’re not sure about how much power this would produce but it would probably be fun to play around with.
Following that is a follow up post about Printrbot, an inexpensive 3D printer which we previously posted about. It was a successful Kickstarter project a couple of months ago and now the design files have been released into the wild. Check it out!
Finally we finish off with a post about how to build a solid-state Tesla coil. It’s presented in an Instructable with 12 easy steps so that you too can feed your high-voltage addiction.
