Starlino is building a Quadcopter, the design is based around the Acc_Gyro Board that he designed and is being sold by our friends over at Gadget Gangster. It uses PID along with a simplified Kalman Filter. “I did some tests on the lift force potential of this frame+motors+props, and was surprise to find out it performed better than some entry-level brushless motors. The lift force of this platform is up
Remember the Multimeter Clock article last month? I just got the full build log up. Lots of people wanted the CNC files so that they could cut their own clock, these DXF files are also available on the Multimeter Clock project page. If you want to make your own there’s a kit available. If you missed the video of the clock in action last time here it is again.

If you have ever been in a remote area and pulled out your laptop I bet you couldn’t find any open WiFi hotspots. Well with this Wind Turbine powers WiFi-Repeater that Dan Lampie and David Brenner from the Rochester Institute of Technology built that problem has been solved on a tiny budget. A highly directional antenna is used to send and receive the WiFi data from a location with internet
Spiral Brain (who was a recent contest winner) has made an interesting Spinning Mirror Laser Project. At first when I watched the video the beginning looked like someone was spinning a few bright LEDs in their hands on a dark night. The patterns that followed show off the capability of the system to make some nice looking complex pattens. “The main hardware setup consists of a Laser and two motors.
