Nin10do Retro Game Console Stands Above All Others

July 9, 2015 by Will Sweatman 22 Comments

If your living room entertainment area is not home to a Raspberry Pi based retro game console, you no longer have any excuses. Break out your soldering iron and volt/ohm meter and preheat the 3d printer, because you will not be able to resist making one of the best retro game consoles we’ve ever seen – The Nin10do.

It’s creator is [TheDanielSpies]. Not only did he make the thing from scratch, he’s done an extraordinary job documenting all the build details, making it easier than ever to follow in his footsteps and make one of your own. He designed the case in Autodesk and printed it out with XT Co-polyester filament. He uses a Raspi of course, along with an ATX Raspi board from Low Power Labs to make the power cycling easier. There’s even a little stepper that opens and closes a cover that hides the four USB ports for controllers. Everything is tied together with Python, making the project super easy to modify and customize to your liking.

All code, schematics and .stl files are available on his github. It even has its own Facebook page! Be sure to check out the vast array of videos to help you along with your build.

Writing Doom For The Raspberry Pi

July 6, 2015 by James Hobson 35 Comments

We’ve all seen Doom played on the Raspberry Pi before… but this isn’t a port of the game. No, this was a school project at the Imperial College of London — writing the game in bare assembly. They wrote it from scratch.

bare metal doom thumbnail — Complete with a custom home made controller connected directly to the GPIO pins!

Yep. There’s not even an operating system on the Pi. It’s 9800 lines of bare metal ARM assembly. If that doesn’t hurt your brain we dunno what does!

They are using the official textures from the game, and it’s not quite a perfect replica — but it’s pretty darn close.

Part of the project was to build an emulator to make it easier to test the game, but it didn’t work out the greatest — so most of the actual game development was performed on the actual hardware. Yikes!

Stick around after the break to see Doom in all its former glory. Top notch work guys!

The First PipBoy We’ll See This Year

June 20, 2015 by Brian Benchoff 27 Comments

You heard that we’re shutting down Hackaday on November 11, 2015, right? That’s the release of Fallout 4, and trust me: I’m not getting anything done that day. A new game in the Fallout series means more power armor cosplay builds, and hundreds of different wearable electronics from the friendly folks at Vault-Tec. I speak of the PipBoy, the wrist-mounted computer of the Fallout series, and [THEMCV] built the first one we’ll see this year. It won’t be the last.

The PipBoy [THEMCV] created is the 3000a model, the same one found in Fallout 3 and New Vegas. We’ve seen a few real-live versions of the PipBoy before; this one used the PipBoy prop that came with the Amazon exclusive special edition of Fallout 3. Things have changed in the years since the release of Fallout 3, and to build his PipBoy, [THEMCV] just bought one from Shapeways.

The electronics consist of a Raspberry Pi Model A, 3.5″ LCD, a battery pack, and a great piece of software to emulate the software of the PipBoy 3000. It looks great, but [THEMCV] still needs to find a few retrofuturistic buttons and dials to complete the PipBoy experience.

Video below.

The Live Still Life

June 14, 2015 by Anool Mahidharia 15 Comments

Here’s a project that brings together artist [Justus Bruns] and engineers [Rishi Bhatnagar] and [Michel Jansen] to collaborate on an interactive work of Art. The Live Still Life is a classic still life, streamed live from India to anywhere in the world. It is the first step towards the creation of an art factory, where hundreds of these works will be made, preserved and streamed.

The Live Still Life is a physical composition of fresh fruit and vegetables displayed on a table with flatware, cutlery and other still objects. This is located in a wooden box in Bangalore. Every minute a photo is taken and the image is streamed, live, accessible instantly from anywhere in the world. Les Oiseaux de Merde’s Indian curator is on call to replace the fruit the minute it starts to rot so as to maintain the integrity of the image. In this way, while the image remains the same, the fight against decay is always present. The live stream can be viewed at this link.

The hardware is quite minimal. An internet connected Raspberry Pi model B, Raspberry Pi camera module, a desk lamp for illumination and a wooden enclosure to house it all including the artwork. Getting the camera to work was just a few lines of code in Python. Live streaming the camera pictures took quite a bit more work than they expected. The server was written using a module called Exprestify written on top of Express JS to facilitate easier RESTful functions. For something that looks straightforward, the team had to overcome several coding challenges, so if you’d like to dig in to the code, some of it is hosted on Github or you can ask [Rishi] since he still needs to clean it up quite a bit.

Wifibroadcast Makes WiFi FPV Video More Like Analog

June 13, 2015 by Elliot Williams 23 Comments

Normal WiFi is not what you want to send video from your quadcopter back to the first-person-view (FPV) goggles strapped on your head, because it’s designed for 100% correct, two-way transmission of data between just two radios. Transmission of analog video signals, on the other hand, is lossy, one-way, and one-to-many, which is why the longer-range FPV flights all tend to use old-school analog video transmission.

When you’re near the edge of your radios’ range, you care much more about getting any image in a timely fashion than about getting the entire video sequence correctly after a delay. While WiFi is retransmitting packets and your video is buffering, your quadcopter is crashing, and you don’t need every video frame to be perfect in order to get an idea of how to save it. And finally, it’s just a lot easier to optimize both ends of a one-way transmission system than it is to build antennas that must receive and transmit symmetrically.

And that’s why [Befinitiv] wrote wifibroadcast: to give his WiFi FPV video system some of the virtues of analog broadcast.

SamplerBox Uses Raspberry Pi 2 To Make Music

June 12, 2015 by Theodora Fabio 16 Comments

[JosephErnest] wanted a cost-effective alternative to the commercially available MIDI samplers and expanders on the market. He also wanted to avoid being tethered to a computer all the time. His solution is the SamplerBox, a standalone drop-and-play sampler that costs less than 100 euros to make. Simply insert an SD card with your sample set in WAV format, boot it up, and play it through your keyboard or MIDI controller to your heart’s content!

[JosephErnest] used a Raspberry Pi 2 in the SamplerBox because it provided higher performance. He wasn’t thrilled with the sound quality of its built-in soundcard, so he installed a USB DAC PCM2704 (an older model, but any USB DAC will do) to output the audio. He also installed a USB card reader to make switching SD cards containing sampler sets easier while keeping the Pi 2’s own microUSB card exclusively for the OS and software. Both a DIN MIDI connector and USB are included as MIDI inputs in the design. If you only plan to use a USB, the MIDI connector can be omitted from the build. The software is written in Python and cython which allows the Pi 2 to have over 128-voice polyphony. Users can also create their own sample sets to use with the SamplerBox. Preset changes can be made on the fly. All we need to rock out are some music lessons!

Portabilizing The Kinect

June 11, 2015 by Brian Benchoff 37 Comments

Way back when the Kinect was first released, there was a realization that this device would be the future of everything 3D. It was augmented reality, it was a new computer interface, it was a cool sensor for robotics applications, and it was a 3D scanner. When the first open source driver for the Kinect was released, we were assured that this is how we would get 3D data from real objects into a computer.

Since then, not much happened. We’re not using the Kinect for a UI, potato gamers were horrified they would be forced to buy the Kinect 2 with the new Xbox, and you’d be hard pressed to find a Kinect in a robot. 3D scanning is the only field where the Kinect hasn’t been over hyped, and even there it’s still a relatively complex setup.

This doesn’t mean a Kinect 3D scanner isn’t an object of desire for some people, or that it’s impossible to build a portabilzed version. [Mario]’s girlfriend works as an archaeologist, and having a tool to scan objects and places in 3D would be great for her. Because of this, [Mario] is building a handheld 3D scanner with a Raspberry Pi 2 and a Kinect.

This isn’t the first time we’ve seen a portablized Kinect. Way back in 2012, the Kinect was made handheld with the help of a Gumstix board. Since then, a million tiny ARM single board computers have popped up, and battery packs are readily available. It was only a matter of time until someone stepped up to the plate, and [Mario] was the guy.

The problem facing [Mario] isn’t hardware. Anyone can pick up a Kinect at Gamestop, the Raspberry Pi 2 should be more than capable of reading the depth sensor on the Kinect, and these parts can be tied together with 3D printed parts. The real problem is the software, and so far [Mario] has Libfreenect compiling without a problem on the Pi2. The project still requires a lot of additional libraries including some OpenCV stuff, but so far [Mario] has everything working.

You can check out his video of the proof of concept below.
