[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!
For a lot of us some sort of audio circuit was our first endeavor into electronics. Speak and Spell, atari punk console, LM386 in a mint tin, sound familiar? If not, you should do yourself a favor and knock out a couple of those simple projects. For those of us who have done a bit of what the kids are calling circuit bending, [Nickolas Peter] brings us a familiar hack with his Patient Alpha project. You can see a time-lapse video of the build process and a short demo in the video after the break.
[Nickolas] did a few mods to his 2013 Executor key fob; the obligatory potentiometer for resistor swap is always a crowd pleaser. Adding an audio out via 3.5 mm jack is something that some of us wouldn’t have thought to include, but it lets the Executor scream into your serious audio gear for maximum eargasms. It’s worth mentioning that [Nickolas] does a good job with this hack’s finished look, albeit he started with a product in an enclosure he still goes to the trouble of custom fitting all his bits in an aesthetically pleasing way. And then he made a second.
We have covered circuit bent projects aplenty: from an old school take on circuit bending to one with a ratking of wires built on a proper bit of audio kit. Dig out your soldering iron and dig in.

Introducing the SG-N64 — the Single Game Nintendo 64 Portable Console. You can play any game you want, as long as it’s the Ocarina of Time.
You might be wondering, why would you go to the effort of making a totally awesome portable N64 player, and then limit it to but a single game? Well, the answer is actually quite simple. [Chris] wanted to immortalize his favorite game — the Ocarina of Time. As he puts it, making a SG-N64 “takes the greatness of a timeless classic and preserves it in a body designed solely for the purpose of playing it”.
Inside you’re going to find the motherboard from an original N64, as well as the game cartridge PCB which shed its enclosure and is now hardwired in place. Of course that’s just the start. The real challenge of the build is to add all of the peripherals that are needed: screen, audio, control, and power. He did it, and in a very respectable size considering this was meant to sit in your living room.
Now that is how you show your kids or grand-kids a classic video game. Heck, maybe you can even convince them that’s how all games were sold and played! What’s the fun in being a parent without a bit of trolling?

Certainly everyone remembers passing time in a boring high school class playing games on a graphing calculator. Whether it was a Mario-esque game, Tetris, or BlockDude, there are plenty of games out there for pretty much all of the graphing calculators that exist. [Christopher], [Tim], and their colleagues from Cemetech took their calculator game a little bit farther than we did, and built something that’ll almost surely disrupt whatever class you’re attempting to pay attention in: They built a graphing calculator whac-a-mole game.
This game isn’t the standard whac-a-mole game, though, and it isn’t played on the calculator’s screen. Instead of phyiscal “moles” the game uses LEDs and light sensors enclosed in a box to emulate the function of the moles. In order to whack a mole, the player only needs to interrupt the light beam which can be done with any physical object. The team made extensive use of the ArTICL library which allows graphing calculators to interface with microcontrollers like the MSP432 that they used, and drove the whole thing with a classic TI-84.
This project is a fun way to show what can be done with a graphing calculator and embedded electronics, and it was a big hit at this past year’s World Maker Faire. Calculators are versatile in other ways as well. We’ve seen them built with open hardware and free software, And we’ve even seen them get their own Wi-Fi.

[willrandship] sent in a conversation from Reddit discussing the programming ports inside the Steam controller and their potential for hacking. From the posts and the pictures it seems the radio/SoC and the MCU can be programmed on the board, or at least they both have JTAG headers. The JTAG headers are in the form of “Tag-Connect” pads on the board so it will require the dedicated cable or soldering some hardware to the board temporarily.
From the pictures we can see a NXP LPC11U37F ARM Cortex-M0 and a Nordic nRF51822 ARM Cortex-M0 SoC with integrated Bluetooth low energy. There are only a limited number of Steam Controllers in the wild at this time so we don’t expect much in the way of hacking them thus far. There is a Steam Controller hackaday.io project just started for anyone who would like to contribute to the Steam Controller hacking.

Before the rise of the Nintendo Gameboy, Tiger LCD games were the king of handheld gaming. Inexpensive and appealing to a wide audience, you still often find them “in the wild” or lurking in your house, even today. When [Lee] found a “Wheel Of Fortune” model laying low in a box, having a look inside and turning the handheld into something it’s not.
Being based on a game show, this specific model has a feature most Tiger handheld’s don’t: a cartridge slot. Originally intended to supply additional categories and phrases, the slot is a wide open bus to the internal CPU. It didn’t take long for the some probing with the Bus Pirate to decode the data protocol.
So what does one do with a hacked game show game? Well you could just make it say goofy stuff, or you could make it into a TOTP password generator. Future plans are to take off the computer umbilical cord and bit bang the cart slot with an AVR. Once done anyone, trying to break in to [Lee’s] PC will never suspect the innocent old toy is the key to the kingdom.
Join us after the break for a quick demo video

When the ever-versatile Raspberry Pi was released, the potential for cheap video game emulation was immediately obvious. Some of the very first Raspi projects to hit the internet were arcade cabinets, and it wasn’t long until people were making them portable. A purpose-build Linux distort called RetroPie has become very popular specifically because of the Raspi’s game-emulation potential. However, the actual hardware for these emulation systems isn’t always the most aesthetically (or ergonomically) pleasing. That’s where reddit user [Cristov9000] has managed to stand out from the crowd.
[Cristov9000] accomplished this by combining high-quality design (and 3D printing) with the careful use of original Nintendo parts. Game Boy and SNES buttons and elastomers were used to achieve the correct button feel. Other original Game Boy parts, like the volume wheel and power switch, ensure that the system feels as much like 1989 OEM hardware as possible.
Also impressive is the internal hardware, including 3 custom PCBs used to tie everything together to work via the Raspberry Pi 2 GPIO pins. The display is a 3.5″ TFT screen, and with the 6000 mAh it can handle gameplay for more than 7 hours. Other details, like the integrated mono speaker and rear shoulder buttons complete the experience. Combined with the RetroPie and an assortment of emulators, this is one of the most impressive portable gaming builds we’ve seen, especially among a crowded list of awesome raspi-based Game Boy builds.
