The Homebrew XBox 360 And PS3 Portable

July 8, 2014 by Brian Benchoff 23 Comments

For the past few years now, [Downing] has been working on the dream of all console modders – a console made in the last ten years made portable. He’s spend a lot of time on the effort, and now thanks to a commission, he’s finally done it. Not just one console, either: this thing makes both the Xbox 360 and PS3 a handheld, battery-powered device thanks to some awesome wireless tech and a great deal of skill.

A few months ago, [Downing] and friends [Hailrazer] and [RDC] started a Kickstarter for the Cross Plane, a portable device that uses a wireless HDMI transmitter to offload the heavy and hot parts of running a game to a console, while the display and controls are kept portable. That Kickstarter didn’t see the success [Downing] was looking for, but that didn’t stop one enthusiastic supporter from commissioning a piece.

The display in the Cross Plane is a 7″ HD display, and the latency on the WHDMI transmitter is just about 1ms – basically unnoticeable. The controls on the front of the portable are wired to ‘controller packs’ that plug into the back, one for Xbox and one for PS3. The build quality is immaculate, and if you’ve ever wanted to know how to expertly finish a 3D printed part so it looks like it came off an assembly line, you should probably check out the build log.

Video walkthrough below.

Handheld Game System Powered By Arduino

DIY Handheld Game System

These days, it’s easy enough to play games on the go. If you have a smart phone, you are pretty much set. That doesn’t mean you can’t still have fun designing and building your own portable gaming system, though.

[randrews] did just that. He started out by purchasing a small memory LCD display from Adafruit. The screen he chose is low power as far as screens go, so it would be a good fit for this project. After testing the screen with a quick demo program, it was time to start designing the circuit board.

[randrews] used Eagle to design the circuit. He hand routed all of the traces to avoid any weird issues that the auto router can sometimes cause. He made an efficient use of the space on the board by mounting the screen over top of the ATMega chip and the other supporting components. The screen is designed to plug in and out of the socket, this way it can be removed to get to the chip. [randrews] needs to be able to reach the chip in order to reprogram it for different games.

Once the board design was finished, [randrews] used his Shapeoko CNC mill to cut it out of a copper clad board. He warns that you need to be careful doing this, since breathing fiberglass dust is detrimental to living a long and healthy life. Once the board was milled out, [randrews] used a small Dremel drill press to drill all of the holes.

The final piece of the puzzle was to figure out the power situation. [randrews] designed a second smaller PCB for this. The power board holds two 3V coin cell batteries. The Arduino expects 5V, so [randrews] had to use a voltage regulator. This power board also contains the power switch for the whole system.

The power board was milled and populated. Then it was time to do some measurements. [randrews] measured the current draw and calculates that he should be able to get around 15 hours of play time using the two 3V coin cell batteries. Not bad considering the size.

A Masterpiece Of 3D Printed Case Modding. With An Ouya.

April 30, 2014 by Brian Benchoff 23 Comments

We’ve seen a few of [Downing]’s portabalized console builds before, but this one is his first build in over two years. That’s a lot of time, and since then he’s picked up a lot of great fabrication techniques, making this one of the best looking portables we’ve ever seen. It’s a repackaging of an Ouya, but we won’t hold that against him, it’s still an amazing piece of work.

In the build log, [Downing] started off this build by using a 3D printed enclosure, carefully milled, filled, and painted to become one of the best one-off console repackagings we’ve ever seen. The speaker and button cutouts were milled out, and an amazing backlit Ouya logo completes the front.

Stuffing the Ouya controller inside a case with a screen, battery, and the console itself presented a challenge: there is no wired Ouya controller. Everything is over Bluetooth. Luckily, the Bluetooth module inside each controller can be desoldered, and slapped on a small breakout board that’s stuffed in the case.

It’s a great build, and in [Downing]’s defense, the Ouya is kinda a cool idea. An idea much better suited to a handheld device, anyway. Videos below.

Portable SMT Lab For Hacker On The Go

We admit it, we’re suckers for workbenches and toolboxes. [Jon] must feel the same way, because he built this portable surface mount electronics lab. It’s a beast of a project, which might be why it’s project #666 on Hackaday.io. [Jon] spends a lot of time working off site, and keeps finding himself without proper surface mount soldering tools. Ever tried to stack an 0603 resistor with a 40 watt pistol grip iron? Take our word for it, the results are not pretty.

[Jon] started with two cheap aluminum cases from Harbor Freight. He loaded them up with the typical lab supplies: soldering iron, oscilloscope, multimeter, dual lab supplies, and a good assortment of hand tools. He then added a few choice SMT tools: A hot air tool, a good LED light, and a stereo magnifier. Many of the tools are mounted on DIN rail along the rear of the cases. All the low voltage equipment runs on a common 12V bus.

We really like what [Jon] did with the tops of the cases. Each lid contains a plywood sheet. When the cases are opened, the plywood becomes a work surface. As an added bonus, the wood really strengthens the originally flimsy tool cases. The only thing we would add is a good portable anti-static mat.

The final build is really slick. Once the cases are open, four bolts act as feet. The microscope swings out, and the hot air gun hangs on the right side. Plug in power and you’ve gone from zero to SMT hero in under 1 minute.

RFID Reader Snoops Cards From 3 Feet Away

November 3, 2013 by Marsh 60 Comments

Security researcher [Fran Brown] sent us this tip about his Tastic RFID Thief, which can stealthily snag the information off an RFID card at long range. If you’ve worked with passive RFID before, you know that most readers only work within inches of the card. In [Fran’s] DEFCON talk this summer he calls it the “ass-grabbing method” of trying to get a hidden antenna close enough to a target’s wallet.

His solution takes an off-the-shelf high-powered reader, (such as the HID MaxiProx 5375), and makes it amazingly portable by embedding 12 AA batteries and a custom PCB using an Arduino Nano to interpret the reader’s output. When the reader sees a nearby card, the information is parsed through the Nano and the data is both sent to an LCD screen and stored to a .txt file on a removable microSD card for later retrieval.

There are two short videos after the break: a demonstration of the Tastic RFID Thief and a quick look at its guts. If you’re considering reproducing this tool and you’re picking your jaw off the floor over the price of the reader, you can always try building your own…

Aluminum Unibody Nintendo 64

[Travis] wanted us to take a look at his N64 portable to see if it could be featured on Hackaday. By the looks of it, we’re going to say hell yeah. Everything on this portable N64, down to the buttons, is milled from aluminum. It’s an amazing build that raises the bar of what a portabalized game system can be.

Inside this anodized enclosure is the circuit board from an original N64. To cut down on the size, [Travis] milled a new heat sink for the CPU and GPU. All the games – quite possibly all the games ever released for the N64 – are stored on an SD card and accessed through an EverDrive 64. Two 5000 mAh Lipo batteries provide three hours of play time on a beautiful high-res screen.

What’s even more amazing is that [Travis] machined all the parts on an exceedingly small, manual mini-mill. Truly a portabalized console for the ages.

You can check out a gallery of pics [Travis] sent in and his demo video below.

ContactKey: A Portable, Battery-powered Phonebook

September 22, 2013 by Marsh 5 Comments

contactKey

Although it’s still a prototype, [Russell] tipped us off to his battery-powered device for storing your contacts list: ContactKey. (Warning: Loud sound @ beginning). Sure, paper can back up your contact information, but paper isn’t nearly as cool to show off, nor can it receive updates directly from your Android. The ContactKey displays a contact’s information on an OLED screen, which you can pluck through by pressing a few buttons: either ‘Up,’ ‘Down,’ or ‘Reset’. Although the up/down button can advance one contact at a time, holding one down will fly through the list at lightning speed. A few seconds of inactivity causes a timeout and puts the ContactKey to sleep to conserve battery life.

This build uses an ATMega328 microcontroller and an external EEPROM to store the actual list. [Russell] wrote an Android app that will sync your contact list to the ContactKey over USB via an FTDI chip. The microcontroller uses I2C to talk to the EEPROM, while an OLED display interfaces to the ATMega through SPI. We’re looking forward to seeing how compact [Russell] can make the ContactKey once it’s off the breadboard; the battery life for most smartphones isn’t particularly stellar. Phones of the future will eventually live longer, but we bet it won’t be this one.
