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.

Portable gets a proper home in an arcade controller

[Luke] wanted an arcade-style controller that he could use for some gaming at home. He decided to use a portable game emulator as a base and then added his own joystick and buttons along with a custom case.

The donor hardware is a Dingo A320. It’s a nice little handheld with a 2.8″ screen, and plenty of potential to emulate games like Donkey Kong seen above, or to play homebrew. It’s even been the target of some RAM upgrades we looked in on in the past. The best part for [Luke’s] project is that it includes a video out port.

In the clip after the break you can see that [Luke] now has a compact controller with a huge arcade joystick, four buttons on the top surface, and the rest of the controls all around the edges of the enclosure. The video out option is selected in the menu system, so he preserved the original LCD for use during configuration.

Dingoo A320 RAM upgrade

[Stephanie] beefed up the hardware on her Dingoo A320. She enjoyed the features that the A320 handheld gaming system offered, but wanted the 64mb of RAM available in its bigger brother, the A330. A comparison of the two led her to believe a swap might be possible and after sourcing a pair of replacement chips for $12.50 she took the plunge. Once the solder had cooled it was just a matter of flashing some different firmware to take advantage of the upgrade.
