DIY Hacks & How To’s: Proximity Sensors
Last week I showed how to use a pressure plate switch to activate special effects. This week, I am going to show you how to make a simple proximity sensor. This is basically just an infrared LED and a phototransistor. When a person stands near the sensor, some of the light from the LED is reflected back to the detector. The output signal of the detector can be monitored by an Arduino and used to activate special effects when the person is close enough.
Meet Chris Kippenberger, Drone Cinematographer
Chris Kippenberger works on DIY aerial drones, which he uses to make videos capturing his love of cars and bicycles that would otherwise be expensive or impossible to make. For him, aerial drones are just the tools of his trade, not and end to themselves.

Sergei Takes his Robot for a Walk
Sergei Lupashin demonstrates his tethered robot fotokite at the Drones & Aerial Robotics Conference in New York City.
Lego Desktop Power Supply
I like this creative way of packaging up an ATX power supply that Instructables user jtmanders created. He added terminals for 5v, 3.3v, and GND, a power LED indicator, as well as a power switch
