Portable RetroPie Suitcase For Multiplayer On The Go!

March 5, 2017 by James Hobson 11 Comments

Portable gaming — and gaming in general — has come a long way since the days of the original Game Boy. With a mind towards portable multiplayer games, Redditor [dagcon] has assembled a RetroPie inside a suitcase — screen and all!

This portable console has almost everything you could need. Four controllers are nestled beside two speakers. Much of the power cabling is separated and contained by foam inserts. The screen fits snugly into the lid with a sheet of rubber foam to protect it during transport.

Tucked behind the monitor rests the brains of this suitcase console: a Raspberry Pi and the associated boards. [Dagcon] resorted to using a dedicated sound card for the speakers, diverting the output from the HDMI port. An LCD screen controller was also necessary as the screen had been re-purposed from its previous life as a laptop screen. [Dagcon] offers some tips on how to go about accomplishing this yourself and a helpful Instructables link.

The ‘All-Seeing Pi’ Aids Low-Vision Adventurer

March 4, 2017 by Dan Maloney 12 Comments

Adventure travel can be pretty grueling, what with the exotic locations and potential for disaster that the typical tourist destinations don’t offer. One might find oneself dangling over a cliff for that near-death-experience selfie or ziplining through a rainforest canopy. All this is significantly complicated by being blind, of course, so a tool like this Raspberry Pi low-vision system would be a welcome addition to the nearly-blind adventurer’s well-worn rucksack.

[Dan] has had vision problems since childhood, but one look at his YouTube channel shows that he doesn’t let that slow him down. When [Dan] met [Ben] in Scotland, [Ben] noticed that he was using his smartphone as a vision aid, looking at the display up close and zooming in to get as much detail as possible from his remaining vision. [Ben] thought he could help, so he whipped up a heads-up display from a Raspberry Pi and a Pi Camera. Mounted to a 3D-printed frame holding a 5″ HDMI display and worn from a GoPro head mount, the camera provides enough detail to help [Dan] navigate, as seen in the video below.

The rig is a bit unwieldy right now, but as proof of concept (and proof of friendship), it’s a solid start. We think a slimmer profile design might help, in which case [Ben] might want to look into this Google Glass-like display for a multimeter for inspiration on version 2.0.

IPad Tossed Out For RetroPie Arcade Cabinet Redux

March 2, 2017 by Donald Papp 11 Comments

The naming and remixing in this project can get a little confusing to those unfamiliar with the different elements involved, but what [John Gerrard] has done is take a stylish mini arcade cabinet intended as a fancy peripheral for an iPad and turned it into an iPad-free retro arcade gaming cabinet. He also designed his own power controller for graceful startup and shutdown.

The project started with a peripheral called the iCade (originally conceived as a fake product for April Fool’s) and [John] observed it had good remix potential for use as a mini retro gaming cabinet. It was a good starting point: inexpensively purchased off eBay with suitable arcade-style joystick and buttons, a nice layout, and plenty of hacking potential. With a small variety of hardware from familiar sources like eBay and Aliexpress, [John] rounded up most of what he needed.

$10 Raspberry Pi Zero W Adds WiFi And Bluetooth

February 28, 2017 by Brian Benchoff 168 Comments

The Raspberry Pi was born on February 29th which means we’re only three years away from its second birthday, and a new hardware release from the Pi Foundation is becoming somewhat of a tradition. This year is no different: a new Raspberry Pi has been announced. The Raspberry Pi Zero W is the latest iteration of the Pi foundation’s tiny and extremely inexpensive single board computer. It’s a Raspberry Pi Zero with WiFi and Bluetooth.

The specs of the new Pi Zero W are nearly identical to the previous incarnation of the non-W Zero. It sports a 1GHz single-core processor, 512 MB of RAM, features Mini HDMI and USB OTG ports, uses a micro USB port for power, features the now-standard 40-pin header with four additional pins for composite video and a reset button. This board, like the second hardware revision of the Pi Zero, also features a CSI camera connector.

Of course, the big feature is the addition of WiFi and Bluetooth. The Pi Zero W adds the wireless functionality from the Raspberry Pi 3B. That’s 802.11n and Bluetooth 4.0.

The Pi Zero’s claim to fame was, of course, the price. The original Pi Zero was at first a bit of hardware glued to the cover of the MagPi magazine, later to sell for just $5 USD. The Raspberry Pi Zero W is priced at just $10.

Bring Saturday Mornings Back To Life With This Cartoon Server

February 23, 2017 by Dan Maloney 27 Comments

It was an American ritual for over four decades: wake up early on Saturday morning, prepare a bowl of sugar, and occupy the couch for four glorious hours of cartoons. The only interruptions came when the least-significant sibling had to be commanded to get up to change the channel to one of the two other networks, or when your mom decided to vacuum the TV room. It was a beautiful ritual, but now it’s gone.

Or is it? If you really want to recapture your misspent youth, you can try this Raspberry Pi multi-channel cartoon server with retro TV display. [FozzTexx] started with a yard sale 13″ Zenith set, which languished in his shop for want of a mission. When he found a four-channel video modulator, he knew he had the makings of the full channel-changing Saturday morning experience.

Four Raspberry Pis were configured to serve up four separate streams of cartoons from his Plex server, and after a late Friday night of hacking the whole thing together, each stream was ready to go live at 7:00 AM on Saturday. [FozzTexx] thought of everything — from the pre-“broadcast day” test pattern to actual commercials spliced into the cartoons to the static between the channels, it’s all there in low-definition glory. He even printed up faux TV Guide pages! You can watch a brief demo on [FozzTexx]’ Twitter feed, or you can watch the entire 2-hour Periscope feed if you’re feeling nostalgic.

[FozzTexx] chose UHF channels for his “stations,” so if you want to replicate this build it may pay to bone up on analog TV tuner basics. Or if it’s just the retro look you’re going for, this custom case inspired by a 40s TV might be nice to check out.

PolaPi-Zero For Surprisingly Good Instant Photos

February 18, 2017 by Pedro Umbelino 21 Comments

The ‘Pola’ in the PolaPi is a giveaway for what this Hackaday.io project is. This polaroid-like camera, created by [Muth], is a sort of black and white, blast from the past mixed with modern 3D printing. It is based on a Raspberry-pi Zero with a camera module, a Sharp memory LCD for viewing the image, and a Nano thermal printer to print the actual photo. Throw in some buttons, a battery and a slick 3D printed case and you have your own PolaPi.

Right now it’s already on the second iteration as [Muth]s gave the first prototype to some lucky person. As he had to rebuild the whole camera from scratch, he took advantage of what he learned in the first prototype and improved on it. The camera has a ‘live’ 20fps rate on the LCD and you can take your photo, review it, and if you like the shot, print it. The printed photo is surprisingly good, check it out in the video after the break.

Currently the software is being actively developed and the latest version has, among other things, a slit-scan mode. For those who don’t know, slit-scan photography is a technique that can create some crazy warped and psychedelic effects (in this case, as psychedelic as a black and white photo can be).

We know you want one for yourself. If you don’t want to spend the time installing and configuring your RPi Zero, [Muth] kindly shared an SD card image with everything ready.
