Mr Home Scientist shows us how to Make Silicon Metal using a Thermite including Sand. If you haven’t seen the destructive power of thermite before have a look at this video where some is used to kill a hard drive. If you intend to play with the stuff be very careful and only use it in an environment where there isn’t much around that can’t burn, a kitchen sink
 Using a Parallax Propeller Jason Dorie built this Quadrotor. Watch the video below to see it in action. It looks to be very stable and with the Propeller processor on board there is sure to be no lack of processing power to keep things nice and stable. “The control board is a Parallax Propeller protoboard (a quick prototyping board you can buy for about $20). The only sensor currently
  Check out this Gir Robot Build. This build is a combination of all sorts of odds and ends. I had never seen Gir before, if you are in the same boat you can see more about the Invader Zim characters here. For an eyeballed hand built version it looks great! The eyes and audio really makes this tiny robot come to life. Thanks for sending it in Rangerx52!
 I have seen used eye glasses donation stations here and there but what are the chances that my prescription will match up exactly to what someone in a third world without having 500 people try them on. These Eyejusters are Self Adjusting Eye Glasses so they solve that problem by making one size fit all. Well not exactly, there are actually two types of adjustable lenses that are needed
 If you are going to be building your own go kart, this DIY Electric Go-Kart Project Build is sure to give you lots of ideas. The design isn’t flashy but looks to be functional and lots of fun to drive. I wonder how many out takes there are where it smashes into some of he walls? Looking through some of the other videos on their Youtube channel shows what
Thanks to hairygael for sending in his latest project. “This hand was printed on a 3D Touch and designed in Blender, controled through Netfab and sliced with Kisslicer. This is a video showing the progress after installing and programming the servos and the Arduino board. Sketch for Arduino are available here: Right hand: http://www.thingiverse.com/thing:17773 Left hand: http://www.thingiverse.com/thing:18939“
 Easton LaChappelle (HalfFullEffects from Youtube) just took second place in the world in engineering at the Pittsburgh international science fair. I like the way he created his own servo motor, instead of just bolting a store bought servo into his project he used a DC motor which was connected to a potentiometer. The potentiometer was then used as feedback for determining the exact position of the motor. Watch the
