Self-flying Drone Avoids Obstacles at 30 Miles per Hour

at 2:49 pm. Filed under Complex Hacks, Cool Gadgets

Check out this Self-flying Drone Avoids Obstacles at 30 Miles per Hour. It looks like this technology is
is not just for smart cars trying to avoid pedestrians and parked cars. CSAIL PhD student Andrew Barry has made this project open source for everyone to benefit from. It can fly through the treetops and dynamically avoid branches and tree trunks. It does this by using a stereo vision system.

“Running 20 times faster than existing software, Barry’s stereo-vision algorithm allows the drone to detect objects and build a full map of its surroundings in real-time. Operating at 120 frames per second, the software – which is open-source and available online – extracts depth information at a speed of 8.3 milliseconds per frame.

The drone, which weighs just over a pound and has a 34-inch wingspan, was made from off-the-shelf components costing about $1,700, including a camera on each wing and two processors no fancier than the ones you’d find on a cellphone.”

2.4GHz Waveguide Cantenna with Circular Polarization

at 5:38 pm. Filed under Complex Hacks


If you need to shoot your WIFI further than your regular WIFI can reach you can look into building this 2.4GHz Waveguide Cantenna with Circular Polarization to give you a boost in range.
“I decided to use a cloverleaf antenna as the driven element with a toilet brush holder as the waveguide. It must be noted that the waveguide in this version is not physically connected to the driven element as doing so will affect the VSWR. As I show in testing this is a powerful waveguide when used with a matched antenna with circular polarization and although powerful it is extremely directional with a beam width of 30 degrees.”

Omni Hoverboard

If you are looking for the latest in personal mobility have a look at the Omni Hoverboard. At first I was thinking this video was faked, but in fact this board is real and has recently won a Guinness World Record. Looks very tricky to fly around and as we can see the trials are being done over water for safety. I would have thought plunging into water would not be good for the motors, I wonder if after a plunge much of the parts need to be replaced?

Via: International Business Times

“The Omni Hoverboard features eight propellers and a frame made from carbon fibre. The motors controlling the propellers are powered by 12 lithium polymer batteries, which generate around 40 horsepower, but sadly, this currently generates a combined flying time of only 1.5 minutes.

Acceleration is achieved by squeezing a joystick made from a pair of pliers which makes the hoverboard go higher or lower, and speed up or slow down. The user is securely anchored to the hoverboard using snowboard binding straps, steering the board by physically turning in the air to change its direction.”

DIY Motorized Combo Lock Cracking Device


Have a master lock that you forgot the combination to? Samy Kamkar shows us how to get in with a nice little motorized combo lock cracking device

“Combo Breaker is a motorized, battery powered, 3D printed, Arduino-based combination lock cracking device. It is portable, open source, 3D models provided, and exploits a new technique I’ve discovered for cracking combination locks in 8 attempts or less, but in an even more exciting, automated fashion.”
