The Game Boy Pocket Raspi Mod Puts All Others To Shame

There are hundreds – perhaps thousands – of builds out there on the Internet that put a Raspberry Pi in an enclosure with buttons meant solely for running emulators for old games. This one is unlike any other. Yes, it’s still basically a RetroPi emulator, but this Game Boy Pocket casemod goes beyond any remotely comparable build.

The Game Boy Pocket is incredibly small, but after sanding down the bosses on the inside of the case, gluing the battery door shut, and installing a bit of plastic over the cartridge slot, [WarriorRocker] was able to fit a Raspi inside. The buttons use the same PCB as the stock Game Boy, connected to a Teensy 2.0 board that simulates a USB keyboard.

With the two largest components taken care of, [Warrior] turned his attention to the sound, video and power. The display is a 2.5″ composite LCD that actually fits quite nicely behind the screen bezel. Audio is taken care of by a $3 audio amplifier, a new, smaller speaker, and a side-mounted pot stolen from the original Game Boy guts. There’s no chance on running this with the same 2xAAA cells the original Game Boy Pocket had, so [Warrior] somehow found space for a 2600mAh Li-Poly battery, a step-up regulator, and a charge circuit.

The result is a full-color RetroPi build capable of running for three hours before needing a recharge. All the classic Game Boy games are loaded onto the SD card along with select titles for other systems. The result is one of the best portabalized Raspi builds we’ve ever seen. Video below.

Fight The Google Glass Cyborgs With Glasshole.sh

Glasshole script

We live in a connected world where social media is ubiquitous and many people feel compelled to share every waking moment with anyone who will listen. In this type of world, wearable computers like Google Glass allow us to share experiences like never before. A Glass user can take photos, record video and audio, or potentially even stream video live on the Internet with the greatest of ease. That might be great for the Glass user, but what about the rest of us? As wearable computing becomes more and more mainstream, people are naturally going to become divided on the issue of privacy. Is it a good thing to have “cyborgs” with wearable computers and cameras constantly at the ready, or is it a privacy nightmare? The cyborg war is coming, and [Julian] has already chosen his side.

It would seem that [Julian] lands on the side of the privacy advocates, based on his “glasshole” script. Glasshole is a relatively simple bash script that relies on some other common network security tools to take care of the heavy lifting. The basic premise relies on the fact that every manufacturer of network interface devices is assigned their own MAC prefix. This is a piece of the MAC address that is unique to that manufacturer.

[Julian’s] script uses a utility called arp-scan to obtain a list of all MAC addresses on a given wireless network. It then loops through each address and compares it to the known Google Glass MAC prefix. If it finds a match, it will make an audible beeping noise to alert the script user. The script then launches aireplay-ng in de-authentication mode. This will send spoofed disassociate packets to the client (in this case the Google Glass device), hopefully forcing them to disconnect from the access point. The script runs continuously, ensuring that once the device reconnects to the network it will get booted off once again. The script is designed to be run on a small Linux computer such as a Raspberry Pi or a BeagleBone black. This way, the user can carry it around with them as a sort of portable defense mechanism.

How do you fit into the cyborg war? Will you stand proudly with your computer on your face for all to see? If so, what kind of countermeasures would you deploy to prevent this type of attack from working on you? If not, what other types of interesting attacks can you think of to keep the cyborgs at bay?
