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 output.

The core of the build is an FPGA which is used to handle pixel decoding and also handles the HDMI output. The FPGA allows for a speed high enough to handle all the data that is required, although [Stephen] still has to iron out some screen-filling issues, add sound over HDMI, and take care of a few various pixel glitches. To turn this hack into a complete hodgepodge of adapters, though, [Stephen] has also added an SNES controller adapter to the Game Gear as well. Nintendo has featured Sonic in many of its games, so although we may have disagreed back in the early 90s we think that this Sega/Nintendo pairing is not crossing any boundaries anymore.

Game Gears have had their share of other modifications as well to make them more capable as a handheld system than they were when they were new. We’ve also seen them turned into a console system (they were Master System compatible, after all) and converted into other things entirely, too.

Fight a Minotaur with this Gorgeous Handheld

[Jason Carlson]’s favorite game as kid was 1983’s Treasure of Tarmin by Intellivision, a maze game that eventually came to be called Minotaur. As an adult there was only one thing he could do: remake it on a beautiful Arduino-based handheld.

[Jason] built the handheld out of a small-footprint Arduino Mega clone, a 1.8” LCD from Adafruit, a 5 V booster, a 1” speaker and vibe motor for haptic feedback. There are some nice touches, like the joystick with a custom Sugru top and a surprisingly elegant 2 x AA battery holder — harvested from a Yamaha guitar.

The maze maps are all the same as the original game, which [Jason] found online, but he stored the maps as bytes in an array to speed up the game—there was a flicker in the refresh already. However he added a progress map so players could see every area that was explored. In addition to Minotaur [Jason] also added remakes of Tetris, Simon and Snake, simpler games he wrote to test out the hardware.

We’ve published a bunch of handheld gaming projects over the years, including putting a Pi Zero in a GameBoy, building a throwback handheld, and playing Ocarina of Time on a N64 handheld.

MP3 Player and Handheld GPS is an Odd Combo Work Of Art

We think [Brek Martin] set out to build a handheld GPS and ended up adding an mp3 Player to it. Regardless, it’s beautifully constructed. Hand built circuit boards and even a custom antenna adorn this impressive build.

The core of the build is a 16 bit microcontroller a dsPIC33FJ128GP802 from Microchip. It’s a humble chip to be doing so much. It uses a UBlox NEO-6M positioning module for the location and a custom built QFH antenna built after calculations done with an online calculator for the GPS half. The audio half is based around a VLSI VS1003b decoder chip.

The whole build is done with protoboard. Where the built in traces didn’t suffice enamel and wire wrap wire were carefully routed and soldered in place. There’s a 48pin LQFP package chip soldered dead bug style that’s impressive to behold.  You can see some good pictures in this small gallery below.

Upgrade The Graphics On A Sega Game Gear To Mental

[Nino K] built a portable game player for text adventures. He decided he had spent enough time with the ATmega328 kit from NerdKits to build a more advanced project.

To start with, he built a prototype PCB and tested out the concept. It worked so he began on the real thing. He tore out the guts from a broken Game Gear, saving some parts like those responsible for supplying power. Impressively, he etched his own replacement boards for the Game Gear’s control pads; surprising himself at how simple it ended up being. He fit a 16×4 LCD into the space previously occupied by the Game Gear’s screen.

The program itself is a simple text adventure of his own creation. He even added little 8-bit sprites. The story is classic, a princess has gotten herself in some trouble and a brave hero has been coerced into saving her. Last, he added some music and sound effects from Zelda with a piezo buzzer.

This project is guaranteed to disappoint a visiting younger cousin or relative, but we like to think of that as a feature and not a bug. Great work!

Give In To Nostalgia With a Retro Game And Watch

One of the earliest Nintendo products to gain popularity was the Game and Watch product line. Produced by Nintendo between 1980 and 1991, they are a source of nostalgia for many an 80s or 90s kid. These were those electronic handheld games that had pre-drawn monochrome images that would light up to make very basic animations. [Andrew] loved his old “Vermin” game as a kid, but eventually he sold it off. Wanting to re-live those childhood memories, he decided to build his own Game and Watch emulator.

The heart of [Andrew’s] build is a PIC18F4550 USB demo board he found on eBay. The board allows you to upload HEX files directly via USB using some simple front end software. [Andrew] wrote the code for his game in C using MPLAB. His device uses a Nokia 5110 LCD screen and is powered from a small lithium ion battery.

For the housing, [Andrew] started from another old handheld game that was about the right size. He gutted all of the old parts and stuck the new ones in their place. He also gave the housing a sort of brushed metal look using spray paint. The end result is a pretty good approximation of the original thing as evidenced by the video below.

Handheld Linux Terminal Gets an A+

Are you all thumbs when it comes to Linux? If you follow [Chris]’s guide to building a handheld Linux terminal, that particular condition could work to your advantage. His pocket-sized machine is perfect for practicing command line-fu and honing your scripting skills on the go.

[Chris]’s creation is built around a Raspberry Pi A+ that he stripped to its essentials by removing the GPIO pins, HDMI and USB ports, the audio port, and the camera and display ports. It’s housed in a pair of plastic 2.5″ hard drive enclosures connected with a piano hinge, making it about the size of a Nintendo DS. The display is an Adafruit PiTFT touch screen and in order to save space, he soldered it directly to the Pi.

The 2.4GHz wireless thumb keyboard has all the special characters necessary for Linuxing, but the four USB ports from a dismantled hub provide flexibility. If [Chris] were to make another one, he might use this slightly larger screen from Tindie and add some charging ports to the case.

Phoenard, A Prototyping Gadget

The Hackaday Prize party wasn’t just about the five finalists; actually, there were more THP entries in attendance – All Yarns Are Beautiful, OpenExposer, M.A.R.S., a 3D scanner, and a few more that I’m forgetting – than actual finalists. In addition, a number of people brought projects that had never seen the light of day, like [Ralf] and [Pamungkas]’ Phoenard.

Phoenard is a Kickstarter project the guys launched at the prize party, something they could attend as a little side trip after manning the ‘maker’ part of the Atmel booth at Electronica. They’ve come up with a tiny handheld device that can only be described as a ‘gadget’. It has a touchscreen, a battery, an MegaAVR, a few connectors, and not much else. What makes this project cool is how they’re running their applications. A bootloader sits on the AVR, but all the applications – everything from a GSM phone to an MP3 player – lives on a microSD card.

The Phoenard guys have come up with a few expansion modules for Bluetooth LE, GSM, GPS, and all the usual cool modules. Plugging one of these modules into the back of the device adds capability, and if that isn’t enough, there’s an old 30-pin iPhone connector on the bottom ready to accept a prototyping board.

Video of these guys below.
