[Terence Bordelon] sent in his impressive UAV (Unmanned Arial Vehicle). The hack is a culmination of his other projects. It can be turned to fully automatic at the flip of a switch. It will fly itself to gps way points, land, and take off. The UAV has a range of 100km thanks to his home built RF Unit which runs on ham bands. The brains of the setup is his custom IMU (Inertial Measurement Unit). The unit is controlled by his ground station which either allows him to fly it normally or toggle through the various modes.

Modified RX7 dimmer control
We were a little surprised when we learned the Mazda RX7’s high beams were controlled by ECU, compared to typical cars using just a toggle switch. Ubermodder [Trent Bruce] realized how much of a pain in the rear end this can be if the ECU ever burns out, meaning no brights. By using a D-Flip Flop setup in a toggle configuration, he is able to control his once lost high beams. He also points out that if you plan to do any other electronic modifications to the RX7, you should be sure to pay attention to the unusual ground…

Parts: ShiftBrite RGB LED module (A6281)
Macetech’s ShiftBrite is a high-power RGB LED coupled with an Allegro A6281 backpack. The A6281 uses three 10bit pulse-width modulators to mix millions of colors using the red, green, and blue elements in the RGB LED. Multiple modules can be chained together for bigger projects, like the ShiftBrite table.
Below the break we demonstrate a ShiftBrite module using the Bus Pirate. For a limited time you can get your own Bus Pirate, fully assembled and shipped worldwide, for only $30.
