[Demetris] sent in a tip about a project he’s working on: an Open Source Remote Control transmitter. This is one of the most impressive looking RC transmitters we’ve ever seen. The OSRC could be great for a small UAV – just get the GPS position from the aircraft and map it with the transmitter’s screen. There’s also support for … Read the rest
When an earthquake is about to strike in Chile, who do you think is first to sound the alarm? You might be surprised that it’s not the government, but rather a 14 year old boy.
After living through an earthquake in 2010 and seeing the devastation this spring in Japan, Chilean teenager [Sebastian Alegria] decided that he wanted to … Read the rest
[Rob] built this hexapod one day when he had some free time after work. Just like the last hexapod we saw, he based the build on the Pololu design which uses three servo motors for surprisingly reliable movement.
Behold the Land-Bear-Shark, a quadcopter on a rather grand scale. At a full eight kilograms it’s an easy target to compare the [Howard Hughes] behemoth, but in addition to the weight, this still has yet to make its first flight.
To give you some scale to the image above, the board at the center is an Arduino. It controls … Read the rest

Gambiarra also has a connection to recycling, as instead of throwing something used out, it … Read the rest
[Jeri Ellsworth] has been working on a direct conversion receiver using an FPGA as an oscillator and a PC sound card DSP. Being the excellent presenter she is, she first goes through the history and theory of radio reception (fast forward to 1:30), before digging into the meat of the build (parts 2 and 3 are also available).… Read the rest
[Geekabit] wrote in asking if we’d seen the 2011 CCC badges yet. The answer is NO, we haven’t seen them because the image above is the only sneek peek we can find on their broken-certificate website. But we are glad that he shared the link with us, because it does tell the tale of what hardware and firmware features … Read the rest
