The Arduboy is a Kickstarter backed, 8 bit video game console that mimics the look of a very tiny Nintendo Gameboy. The Arduboy Classic is actually using the case, button and LCD screen from a classic Game Boy.
[uXe] is using the same brains, an ATMEGA32U4, along with a 328 as a co-processor to handle the classic “creme-n-spinich” gameboy screen. 2K of dual port ram acts as a buffer between the two micro-controllers meaning they can not only run while not being in lock step with eachother, but that each micro can read or write to the ram at the same time.
Currently the whole setup is spread out on a breadboard while all the interfacing is worked out, but it is working quite well. Future plans are to make a drop in motherboard replacement for the classic game system, and there is ample room for all the new electronics on the original footprint.
If you’re unfamiliar with the Arduboy project, check out our interview with it’s creator, [Kevin Bates]. That and the demo of [uXe’s] hack based on the project are both found after the break.

Wearables are the next frontier of amateur electronics, and [Kevin]’s Arduboy ring is one of the best examples we’ve seen yet.
Inside the Arduboy is an nRF51822 – a chipset with Bluetooth Low Energy, an ARM Cortex M0,256k of Flash, and 16k of RAM. There’s also a an OLED and a touch button for displaying notifications from a phone, with the ability to reply to these notifications.
The enclosure for the ring is rather interesting. It’s a bit thick, but that’s for a reason – there’s a 40mAh battery stuffed along the sides of the ring. The enclosure itself is 3D printed to spec, and contrary to some beliefs, there’s nothing wrong with bending a LiPo cell once. Sure, it only has four hours of battery life with the display on, but it has a 24 hour battery life in standby mode, making it almost useful as an everyday wearable.
This is [Kevin]’s second wearable, the first being the Ardubracelet, an extremely interesting OLED bracelet with three different displays. The Arduboy is much more compact and comes extremely close to looking like a product. You can check out the video of it below.

Making your own Tetris game is almost a rite of passage for hackers — [Kevin] has stepped up the game a little by making this awesome-flexible-triple-displayed-Tetris-watch dubbed the Ardubracelet.
At the recent Maker Faire SF our head editor [Mike] got a chance to meet with [Kevin] from Arduboy who told us about some of his upcoming projects — this wearable was one of them!
It features three super bright OLED screens on a flexible circuit board with conductive touch buttons to continue with the minimalist design. Instead of a wrist strap he’s actually made the ends magnetic to hold it in place — did we mention the battery also lasts for over 10 hours?
At the heart of the flexible circuit board is an Atmega328p, which is the same chip used in the Arduboy (a credit card sized GameBoy). This is just the first prototype but he’s planning on making it even better in the future complete with Bluetooth and some 3D printed parts to make it look a bit nicer.

Why not round out our two-week Bay Area Maker Faire coverage with a Links post? This time around it’s video links. We mixed together a bunch of interesting clips that didn’t get their own video, as well as a dose of what it feels like to walk around the Faire all weekend. Join us after the break for the links.

Think you’ve seen every possible type of Arduino based hand held video game? [Kevin] managed to coax something new out of the theme with a very clever credit card sized console that uses some very interesting construction techniques.
The inspiration for this project began when [Kevin] dropped an SMD resistor into a drill hole on a PCB. This resistor fell right through the hole, giving him the idea creating a PCB with milled cutouts made to fit SMD components. With a little experimentation, [Kevin] found he could fit a TQFP32 ATMega328p – the same microcontroller in the Arduino – in a custom square cutout. The rest of the components including a CR2016 battery and OLED display use the same trick.
The rest of the design involved taking Adafruit and Sparkfun breakout boards, and modifying the individual circuits until something broke. Then, off to Eagle to create a PCB.
[Kevin]’s experiment in extremely unusual PCB design worked, resulting in a credit-card sized “Game Boy” that’s only 1.6 millimeters thick. The controls are capacitive touch sensors and he already has an easter egg hidden in the code; enter the Konami code and the Hackaday logo pops up to the tune of [Rick Astley]’s magnum opus.
Now [Kevin] is in a bit of a bind. He’d like to take this prototype and turn it into a crowd sourced campaign. In our opinion, this “Game Boy in a wallet” would probably do well on a site like Tindie, but any sort of large scale manufacturing is going to be a rather large pain. If you have any wishes, advice, of complaints for [Kevin] he’s got a few links at the bottom of his project page.
