Most of the incredible flight simulator enthusiasts with 737 cockpits in their garage are from the US. What happens when they’re from Slovenia? They built an A320 cockpit. The majority of the build comes from an old Cyprus Airways aircraft, with most of the work being wiring up the switches, lights, and figuring out how to display the simulated world out of the cockpit.
Google Cardboard is the $4 answer to the Oculus Rift – a cardboard box and smartphone you strap to your head. [Frooxius] missed being able to interact with objects in these 3D virtual worlds, so he came up with this thing. He adapted a symbol tracking library for AR, and is now able to hold an object in his hands while looking at a virtual object in 3D.
Heat your house with candles! Yes, it’s the latest Indiegogo campaign that can be debunked with 7th grade math. This “igloo for candles” will heat a room up by 2 or 3 degrees, or a little bit less than a person with an average metabolism will.
Last week, we saw a post that gave the Samsung NX300 the ability to lock the pictures taken by the camera with public key cryptography. [g3gg0] wrote in to tell us he did the same thing with a Canon EOS camera.
The guys at Flite Test put up a video that should be handy for RC enthusiasts and BattleBot contenders alike. They’re tricking out transmitters, putting push buttons where toggle switches should go, on/off switches where pots should go, and generally making a transmitter more useful. It’s also a useful repair guide.
[Frank Zhao] made a mineral oil aquarium and put a computer in it. i7, GTX 970, 16GB RAM, and a 480GB SSD. It’s a little bigger than most of the other aquarium computers we’ve seen thanks to the microATX mobo, and of course there are NeoPixels and a bubbly treasure chest.
The folks at the London-based startup GoCardless have a pool table at their office. Being the techies they are, they decided to build a system that automatically scores games. The results, while not fully complete, are still pretty impressive for something whipped up during a 48 hour hackathon.
The automated score keeper uses a webcam duct taped to the ceiling right above the center of the pool table, The balls – red and yellow balls replace the rainbow of solids and stripes to make things easier – are found using OpenCV.
This build isn’t quite finished yet. The people at GoCardless are looking to improve the accuracy of their setup by using a camera with a higher frame rate and possibly moving on to physics simulation to predict where the balls should be. If these guys get the time, they could add something like augmented reality pool table to improve shot accuracy.
Vidia after the break.

[DJ Sures] got his hands on a plastic Wall-E toy and decided to build a robot that includes a camera, voice recognition, and object tracking. The result is adorable so we’re putting this video before the break:

[Shingo Hisakawa] sent in a tip for a for a neat little box called the Levistone that tracks the Internation Space Station with a laser. His video log goes though all the steps for this great little project.
[Shingo] originally planned to pull orbital data down from NORAD and send that to an ArduinoBT board with ethernet, GPS and compass modules. In the original plan, the Arduino would do the orbit calculations and point the laser using a few servos. There wasn’t much success with making an Arduino do all the work, so the an Android phone stood in for the GPS, compass and connection to the web. The duty of calculating the location of the ISS using GPS and orbital elements was moved onto the Amazon EC2 cloud. The final product looks great, even if it’s impossible to record the beam for the video.
With the ability to calculate the azimuth and elevation of the ISS from any point in the world, [Shingo] came up with SightSpaceStation, a neat mashup of his data and Google Maps. There are also iOS and Android apps for a nice piece of work in augmented reality. It’s a great project that would really compliment the ISS desk lamp we covered a few days ago.
