A Motion Sensing Light For Your Entrance Hallway

Arriving home to a dark house with an armful of anything is usually an exercise in fumbling confusion until someone manages to turn on a light. [Pavel Gesyuk] has circumvented this problem entirely by building and installing a motion detecting entrance light!

[Gesyuk] is using an Arduino clone by the name of  Funduino Mini Pro, a 2-channel, 2-way relay, — he only needed one, but you use what you have on hand — a recycled power supply to convert 220V AC to 5V DC, and an infrared sensor.

The project’s goal — in excess of a lighting solution for an …read more http://pje.fyi/Q0QQ3P

Controlling A Micro Helicopter with a PS2 Controller

The Syma S107G is a venerable stalwart of the micro helicopter market. Affordable, robust, and ubiquitous, the S107G relies on infrared to receive its control signals. Emboldened by the prior work of others, [Robert] set out to control his with a Playstation 2 controller.

In this project, [Robert] is standing on the shoulders of giants, so to speak – we’ve seen others reverse engineer the S107G’s communications protocol before. [Robert] combined the efforts of several others to understand how to send commands to the helicopter, including use of two separate channels for controlling two at once.

With the knowledge of …read more http://pje.fyi/PYq3CM
