Mythical Game Boy Advance Colors Hacked Into Reality

September 15, 2015 by 6 Comments

When it was announced in 2000 at a Nintendo trade show, the Game Boy Advance was clad in beautiful silver plastic, accented with brilliant orange buttons. As is usually the case with product introductions, the first color and style displayed to be public became the most popular. There was one problem with this silver and orange GBA; Nintendo never put it into production. Fast forward fifteen years, and [Michael Choi] decided it was time to make his own silver and orange Game Boy. It’s a great introduction to mold making and very detailed painting, and a useful guide for turning engineering prototypes into beautiful objects.

[Michael]’s build began with an aftermarket shell, painted with Tamiya spray paints. The color is remarkably accurate, considering the only pictures for the silver and orange Game Boy are fifteen years old, and with the right painting technique, these colors are indistinguishable from a properly colored, injection molded piece of plastic.

GBAsquareThe buttons were not as easy as the shell. [Michael] originally decided casting would be the best solution, but after multiple attempts, he couldn’t get the color right. Even with opaque dyes in the resin, the buttons would still come out slightly translucent. In the end, [Michael] decided to paint the original buttons.

This casemod isn’t just about changing the color of the enclosure. [Michael] also wanted is Game Boy to have the backlight found in the second revision clamshell GBA. This was easily acquired on eBay, and with a few slight hardware modifications and a beautiful glass lens to replace the plastic occupying the bezel, [Michael] has a gorgeous Game Boy Advance, taken straight from a press event fifteen years ago.

Xerox PARC Exploding Chip

This Post Will Self Destruct In 10 Seconds

Ah yes, the classic Mission Impossible ultimate message security — after verification and playing the message, poof — it’s gone. You could design explosives into your electronics to have the same effect… or you can use Xerox PARC’s new chip, which features a self-destruct mode.

Wait, what? Yup — some engineer at Xerox decided to develop a chip that can literally self-destruct. It was developed for DARPA’s vanishing programmable resources project, and well, it sounds pretty promising for the future of high-security applications.

Hackaday Prize Semifinalist: Balancing Humanoid Robots

September 14, 2015 by No comments

A few years after we all tire of our remote control BB-8 droids we’ll all have personal human robots designed specifically for human interaction. We’re not there yet, but [Poh Hou Shun] out of Singapore is working on a robot like this for the Hackaday Prize. It’s called OSCAR, the Omni Service Cooperative Assistance Robot.

As with any robotics platform, the use case defines the drive system; you’ll want knobby tires or treads if you’re building a sumo bot, and a strange articulating suspension if you’re driving over alien terrain. OSCAR is built for humans, and this means a humanoid chassis is required. Legs, however, aren’t. Instead of a complex system of motors and joints, OSCAR is balancing on a ball. No, it won’t go up stairs, but neither will many other robots either.

So far, [Poh Hou Shun] has built the basics of a drive system, and it’s surprisingly similar to the BB-8 droids we’re still not tired of yet. On the bottom is a large ball held in place with a spring-loaded retainer. On top of this are three stepper motors, each holding an omni wheel. It will work, there’s no doubt about that, and with the right humanoid chassis, some sensors, and a lot of software, this could be a very cool social robot.

Head Gesture Tracking Helps Limited Mobility Students

September 14, 2015 by 2 Comments

There is a lot of helpful technology for people with mobility issues. Even something that can help people do something most of us wouldn’t think twice about, like turn on a lamp or control a computer, can make a world of difference to someone who can’t move around as easily. Luckily, [Matt] has been working on using webcams and depth cameras to allow someone to do just that.

[Matt] found that using webcams instead of depth cameras (like the Kinect) tends to be less obtrusive but are limited in their ability to distinguish individual users and, of course, don’t have the same 3D capability. With either technology, though, the software implementation is similar. The camera can detect head motion and control software accordingly by emulating keystrokes. The depth cameras are a little more user-friendly, though, and allow users to move in whichever way feels comfortable for them.

This isn’t the first time something like a Kinect has been used to track motion, but for [Matt] and his work at Beaumont College it has been an important area of ongoing research. It’s especially helpful since the campus has many things on network switches (like lamps) so this software can be used to help people interact much more easily with the physical world. This project could be very useful to anyone curious about tracking motion, even if they’re not using it for mobility reasons.  Continue reading “Head Gesture Tracking Helps Limited Mobility Students” →

Debug An IKEA Lamp Hack, Win A Lamp Controller

September 14, 2015 by 61 Comments

[Limpkin], aka Hackaday alum [Mathieu Stephan], is at it again, converting an IKEA lamp into a visual wake-up light. He wants to build an alarm that can be remotely triggered, He’s basing this project around a combination of an ESP8266 that handles the communication and timing, and a pile of 10-watt RGB LEDs. However, he is having a problem: every time he initializes the PWM (pulse width modulation) signalling that will control the level of the LEDs, his ESP8266 dev board reboots. So, he’s offering an interesting bounty for the person who finds the issue: figure it out and he will send you the lamp. Well, the PCB and components, anyway: you’ll have to add your own IKEA lamp. It’s an interesting approach to debugging a hardware problem, so feel free to take a look. The full hardware and software details are on his GitHub repository.

Hackaday’s DC Meetup And Workshops

September 14, 2015 by 6 Comments

Washington DC has a vibrant hardware hacking community and it was out in force on Saturday night. We had over one hundred people through the door at Nova Labs in Reston, Virginia (DC metro area). This sleek and spacious hackerspace opened their doors for a Hackaday Meetup as part of a weekend packed full of activities.

Blinky hats
RPi powered Teletype machine
LED marquee cube
Wyolum reaction time game

The building that Nova Labs moved into not too long ago is a really well-suited area for a Hackerspace. The front half of the building includes a huge open space which has plenty of room for people to set up the hardware they wanted to show off. The back has a full woodshop, machine shop, and more, with classrooms and conference rooms in between.

Above are a set of hats with addressible LED strings wrapped around them which [ArsenioDev] brought along with him. Several members of the Wyolum team are involved with Nova Labs and they were showing off some LED matrix-based projects like the marquee cube and a 3-player reaction time game. And clacking away all night long is a vintage teletype machine that [Bob Coggeshall] fixed and connected to a Raspberry Pi.

The Open, Hackable Electronic Conference Badge

September 14, 2015 by 25 Comments

Electronic conference badges have been around for at least a decade now, and they all have the same faults. They’re really only meant to be used for a few days, conference organizers and attendees expect the badge to be cheap, and because of the nature of a conference badge, the code just works, and documentation is sparse.  Surely there’s a better way.

Enter the Hackable Electronic Badge. Ever since Parallax started building electronic conference badges for DEF CON, they’ve gotten a lot of requests to build badges for other conventions. Producing tens of thousands of badges makes Parallax the go-to people for your conference badge needs, but the requests for badges are always constrained by schedules that are too short, price expectations that are too low, and volumes that are unknown.

There’s a market out there for electronic conference badges, and this is Parallax’s solution to a recurring problem. They’re building a badge for all conferences, and a platform that can be (relatively) easily modified while still retaining all its core functionality.
