Feeling nostalgic? Miss the solid feel of an original Nintendo Game Boy? You could smash a window with one and keep playing Pokemon the whole time! Well, [Raz] was, and he built what might just be the biggest Gameboy ever. Gameboy XXL: The Texas Edition.
Actually, it was commissioned for a Belgian music festival called Nintendoom — picture video game music + rave. Anyway, the organizer thought it would be so cool to have a giant functional Game Boy, so [Raz] got to work. He made it out of 10 square meters of 3mm thick MDF, which he laser cut into shape at the Brussels FabLab. The electronics inside consist of a 19″ LCD monitor, a Raspberry Pi, and a few jumbo size buttons.
It’s pretty freaking awesome. It runs Retropie which allows you to play pretty much whatever game you want. Check it out after the break.

A filmmaker friend of [Thomas] mentioned that she would like to display a triptych at the 2015 Venice Art Walk. This is no ordinary triptych with a frame for three pictures – this is a video triptych, with three displays each showing a different video, and everything running in sync. Sounds like a cool engineering challenge, huh?
The electronics used in the build were three Raspberry Pi 2s and a trio of HDMI displays. Power is provided by a 12V, 10A switching supply with 5V stepdown converters for the Pis. The chassis is a bunch of aluminum bars and U channel encased in an extremely well made arts and crafts style frame. So far, nothing out of the ordinary.
Putting three monitors and three Pis in a frame isn’t the hard part of this build; getting three different displays all showing different videos is. For this, [Thomas] networked the Pis through an Ethernet hub, got the videos to play independently on a RAM disk with omxplayer. One of the Raspberry Pis serves as the master, commanding the slaves to start, stop, and rewind the video on cue. According to [Thomas], it’s a somewhat hacky solution with a bunch of sleep statements at the beginning of the script to allow the boot processes to finish. It’s a beautiful build, though, and if you ever need to command multiple monitors to display the same thing, this is how you do it.
Two years ago, [Matt] made a move away from his software hacks and into the physical world. He was part of a pilot program to provide mentorship to children as part of the Maker Education Initiative. This program gave him access to 3D printers, CNC machines, and laser cutters within the New York Hall of Science makerspace. [Matt] chose to build an illuminated notification cube for his first physical project. The idea being that smart phones have so many alerts, many of which are unimportant. His project would help him to visualize and categorize each alert to better understand its importance.
The brain of the system is a Raspberry Pi. [Matt] found a Python library that allowed him to directly control an RGB LED strip based on the LPD8806 chip. He wired the data pins directly to the Pi and used an old 5V cell phone charger to power the LEDs. The strip was cut into smaller strands. Each face of the cube would end up with three strands of two LEDs each, or six LEDs per side. [Matt] found a mount for the Pi on Thingiverse and used a 3D printer to bring it into existence. The sides were made of frosted laser cut acrylic. The frosted look helps to diffuse the light from the LEDs.
Over time [Matt] found that the cube wasn’t as useful as he originally thought it would be. He just didn’t have enough alerts to justify the need. He ended up reprogramming the Pi to pull weather information instead, making use of the exact same hardware for another, more useful purpose.
[Matt Reed] used a few off-the-shelf parts and built a Raspberry-Pi based BitTorrent Sync client to help backup files. What makes it stand out is the idea of using a Mason Jar as the enclosure and the nice build finish. Mason Jars have long been used to preserve food. [Matt] wanted to use the Mason Jar to help preserve family memories.
Basically, he just stuffed a Raspberry Pi inside a jar with some LED’s and put BitTorrent Sync on it. He started off with a nice, square piece of wood and mounted the lid on it. Holes were drilled to fix the four LED’s and faux crystal drawer pull knobs. The Pi was connected to power and Ethernet and the LED’s wired up. The software is quite straightforward – just install BitTorrent Sync on the Raspberry Pi. He wrote a Node.js script to constantly check if BitTorrent Sync is transferring any data, and if it is, blink the LED’s so it looks cool. If no data is being transferred, the LED’s just glow solid red. Once it is plugged into power and connected to the internet, any photo or video (or any file for that matter) that is put inside a special folder called “Preserve” on any of his devices, gets sync’ed and copied to the “Raspberry Preserve” – preserved for posterity.
Why do light bulbs, furnaces, outlets and even automated blinds get all the home automation love? Won’t somebody think of the kettle!? How are we suppose to ensure tea-time is always a button click away? Tired of his lack of options for remotely controlling his kettle, [FatCookies] decided to make his own WiFi enabled kettle.
He started by ripping up an old power supply enclosure he had lying around, and it happened to be just big enough for a Raspberry Pi. He then added a 2-way relay board designed for handling mains voltage at a high amperage — quite necessary for something that draws as much as a heating element.
From there it was just a matter of wiring the relay board to the GPIO on the Pi, and to the kettle itself. For safety reasons, he’s powered the kettle and the Pi separately — and don’t worry, he left the safety switch in the kettle intact.
And while we have to admit, it’s not the most aesthetically pleasing hack, it certainly does the trick — and didn’t cost [FatCookies] much at all.
But if you’re more of a coffee kind of person — you could also replicate this hack with a coffee maker instead.
Launched over 10 years ago, the Squeezebox was one of the most popular network streaming devices sold. The idea was simple: put some MP3s on a computer, connect the Squeezebox to a LAN, and stream those tunes. Someone at Logitech had the brilliant idea that MP3s and other audio files should be stored in an online service a while back, something that didn’t sit well with [Richard]. He went out and built his own Squeezebox with a Raspberry Pi, out of an ammo box, no less.
Most of the project is based on another Squeezebox Raspi mashup over at Instructables. This was a wall-mounted project, and not encased that keeps 7.62 ammunition secure during transport. It did, however, provide enough information for [Richard] to use in his project.
To make his Squeezebox look a little more industrial and sturdy, he cut a few holes in a NATO ammo can for speakers, a TFT touchscreen display, and a USB charger port. Inside, a pair of powered speakers, a USB hub, and a powerbank were added, making this a portable streaming solution that can take a beating.
We’ve seen a lot of projects recently that take advantage of the Raspberry Pi 2’s augmented abilities. With the increased processor power and double the memory, it puts a lot more utility in the user’s hands. The latest project that takes advantage of this is the Pi-nk, which combines a Pi with a Kindle for some text-based awesomeness.
[Guillaume] has put together this detailed how-to which, unlike other builds we’ve seen in the past, uses wireless instead of USB for almost all of the connections, including the keyboard. Granted, this isn’t a new idea, but he’s presenting the way that he did it. To that end, all of the commands you’ll need to use are extremely well documented on the project page if you want to build your own. When everything is said and done, you’ll be SSHing into the Pi from the Kindle and using the popular “screen” program to get the Pi to use the Kindle as its display.
Additionally, [Guillaume] has posted some schematics for custom enclosures for the Pi-Kindle pair if you’re more ambitious. He points out that the e-ink display is great if the Pi is being run in text or command-line mode, and we’d have to agree. This is a very clean pairing of these devices and puts the strengths of both to great use!
