If you use your CNC machine to make metal parts you will most likely need a way to soften the edges a bit before you use the pieces. Neo7cnc built this quick and dirty DIY Parts Tumbler using a plastic coffee can filled with BB pellets, a small motor slowly turns the can and after a few hours your parts have rounded edges and have a nice polished finish.Â
If you have an iPad you know that there will come a time when you need to have it stand on it’s own.

When you have a circuit idea in your head you used to reach for a napkin and a pen. More recently you probably launched a browser on whatever computer is closest but what if you could simply grab an iPad. Well that day has come. Now you can design your next circuit design on your iPad which is probably closer to you than your computer. It might not be
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
 John Duffy built this Wirelessly Charging LED Light in a strong PVC Plumbing housing. It uses an inductive loop for charging which means the case can be made completely waterproof by permanently sealing the unit. Given that it is tiny and made from PVC it would be very robust. I am thinking that you could run over it with a car and it would suffer no damage. He
  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!
