I had recently bought an original Gameboy DMG from Good Will for a whopping $5.00, condition unknown. Taking a gamble, I purchased it and took it home to find that it had severe damage caused by a battery that exploded and leaked all over the mainboard.
I had also recently started looking on eBay for the elusive Gameboy Light. It’s a system I have always wanted but could never allow myself to buy since they are pretty expensive on eBay. The Gameboy Light is the Gameboy Pocket with an Indiglo light and was only released overseas in Japan.
I had bought a Raspberry Pi a while back and really didn’t know what I wanted to do with it. At that moment, like a Reese’s Peanut Butter cup, it dawned on me – could the Raspberry Pi be used with a Gameboy?

This is Part 2 of a series of blogs regarding the development of a wall-mounted server based on the Raspberry Pi, featuring WiFi and a colour touchscreen. Part 1 can be found here.
The enclosure I’m using, a re-purposed room thermostat casing, places some very tight constraints on the dimensions of the Raspberry Pi and PiTFT board.The plastic used in the case is quite sturdy, and is at least 2mm in thickness. Therefore the real inner depth of the case is about 12mm. As for the width of the Pi, we need to shave at least 4mm from the side. The Pi itself is 86mm wide, same with the PiTFT board, so we will need to find a way of making it closer to 82mm.

When you start hooking peripherals such as keyboard, WiFi dongle and mouse to a Raspberry Pi it’s not long before you run out of ports and need a USB hub, preferably powered so that it can supply the RPi as well. At this point cabling starts to take over your workspace.
The Raspiado board, launched on Kickstarter should help cut down on the tangle; it has the same dimensions as the RPi board and mounts on its underside via two (stackable) standoff pillars to leave the top GPIO and camera connectors open to whatever you’re building so that it won’t impede the RPi’s connectivity options.

Watch signals propagate through basic digital circuits. Emulate any two-input logic gate using just one rLogic board and one jumper. To order rLogic+, the breadboard compatible variant, simply order normal rLogic. When the survey is sent out you will indicate which you would like.
rLogic is a basic breakout board for the Fairchild Semiconductor TinyLogic® series of Configurable Logic Gates, with an LED for watching signals and cleverly arranged header pins for simple conversion from gate to gate. Different from programmable logic, configurable logic is manually changed through rewiring using a simple shunt (AKA, a jumper), allowing you to easily and quickly morph a single pinkie sized board into any basic logic function you might need. rLogic requires no prior knowledge, but if knowledgeable of basic digital circuitry then you may jump right in with creating. If not, then a few minutes with rLogic boards will begin to teach you the basics of digital electronics.

RS Components just announced the availability of Raspberry Pi Model B +.
After the success with Model B, three million items sold, Raspberry Pi has been enhanced with several new features and functions included in the Model B + version. Apparently:
the energy consumption of the Pi Model B+ are significantly lower (between 20% and 30% less than the B)
I / O lines have been expanded replacing the GPIO socket with one for 40-pin connectors (pinout for the first 26 contacts remains identical to that of the original Model B)
The number of USB ports is doubled from two to four
The new Raspberry B+ is here for RasPi lovers - [Link]

Anandtech tears down the LG G Watch and Samsung Gear Live:
The G Watch turns out to be pretty easy to take apart. There are four Torx T5 screws on the back, removing them gives you access to its internals. The 400mAh battery is integrated into the back cover. ARM’s teardown confirms 3.8V chemistry, resulting in a 1.52Wh total capacity.
The logic board in the Gear Live is a bit more complex. There’s a second layer stacked on the main logic board that also acts as an RF can.

For makers, engineers, and DIY enthusiasts, Shenzen, China is a bit of a dream world. Once you get past the shoddy internet and questionable origin of the components you buy in the markets, you realize just how quickly and easily you can get almost anything done. For about $100 you can get a couple dozen 4-layer PCBs and a stainless steel stencil. For another $50 you can get it in 2 days. That’s seriously cheap, and the game changes when you have such ready access to fast, cheap manufacturing. The electronics market puts Wal-Mart to shame, and you can’t walk 20 feet without bumping into someone carrying a reel of components or pushing a cart full of capacitors. I was there with Lavie Sak, my co-founder for Shot Stats, makers of Challenger, a tennis swing tracking device. We were excited and overwhelmed by this new place and it seemed like anything was possible.

Nodcah made this Instructables detailing the build of his DIY fingerprint scanning garage door opener:
As a person without a car, I don’t need to carry keys around everywhere I go. Because of this, I’ve been locked out of my own house several times. It’s a pain to wait for someone with a key, so I thought I would do something about it.
This project is my way of solving this problem, while getting the chance to interface with an awesome fingerprint scanner (aka: FPS).
Also, this module isn’t restricted to just garage doors, for you can create different kinds of simple motorized locks to suit your needs.
