Hackaday Links: July 23, 2017

Hey, you know what’s happening right now? We’re wrapping up the third round of The Hackaday Prize. This challenge, Wheels, Wings, and Walkers, is dedicated to things that move. If it’s a robot, it qualifies, if it’s a plane, it qualifies, if it passes butter, it qualifies. There’s only a short time for you to get your entry in. Do it now. Superliminal advertising. Speaking of the Hackaday Prize, this project would…

Hackaday Prize Entry: Minimalist HTTP

For his Hackaday Prize entry, [Yann] is building something that isn’t hardware, but it’s still fascinating. He’s come up with a minimalist HTTP compliant server written in C. It’s small, it’s portable, and in some cases, it will be a bunch better solution than throwing a full Linux stack into a single sensor. This micro HTTP server has two core modules, each with a specific purpose. The file server does exactly…

Automatic Phone Dialer Illuminates Inner Workings

The invention of the transistor ushered in a lot of technologies that we now take for granted, and one of the less-thought-about areas that it improved living conditions worldwide was by making the touch-tone phone possible. No longer would the world have to fuss with dials to make phone calls, they could simply push some buttons. This technology is still in use today, and it is possible to build external phone dialers that use these tones to…

As the adage goes, “if you want something done right, do it yourself.” Desirous of a tablet but preferring to eschew consumer models, [Stefan Vorkoetter] constructed his own compact and lightweight Raspberry Pi tablet, covering several extra miles in the process. The tablet makes use of a Raspberry Pi 3 and the official touchscreen, with the final product marginally larger than the screen itself. Designed with a ‘slimmer the…

Game Gear HDMI with SNES Controller

With its backlit color screen and Master System compatibility, the Game Gear was years ahead of its main competition. The major downside was that it tore through alkaline batteries quickly, and for that reason the cheaper but less equipped Game Boy was still able to compete. Since we live in the future, however, the Game Gear has received new life with many modifications that address its shortcomings, including this latest one that adds an HDMI…
