The Realtek RTL8188CUS is a strong contender, as the fact that it comes in both USB and module versions should make its eventual integration seamless.Р”В®ven if youРІР‚в„ўre not interested in the idea of hiding security appliances inside of everyday objects, this project is a fascinating glimpse into the process of creating your own custom Linux board. Naturally a device like this will need WiFi, but until can decide on which chip to use, the plan is to just use a USB wireless adapter. It will be paired with 1 GB of DDR3 RAM, and an SD card to hold the operating system. The A33 boasts a quad-core Cortex-A7 clocked at 1.2 GHz, and offers USB, I2C, and SPI interfaces for expansion.

As of right now heРІР‚в„ўs planning on using the Allwinner A33 to power the board, a sub-$10 USD chipset most commonly seen in low-cost Android tablets. So far, has decided on his primary components and is working on a larger development board before really going all-in on the miniaturization process. The RTL8188CUS is likely to get integrated later on. Obviously such a board would be of great interest to the larger hacker and maker community.

With none of the currently available single-board computers (SBCs) meeting his list of requirements, the first step is to build a miniature Linux machine thatРІР‚в„ўs got enough processing power to run useful security tools locally.

aims to make this a 100% free and open source device, starting from the tools heРІР‚в„ўs using to produce the CAD files all the way up to the firmware the final hardware will run. This project is still in the early stages, but we like what we see so far. Which is why is hoping to build one into a standard USB wall charger. WeРІР‚в„ўve seen both commercial and DIY versions of this concept, and as you might expect, one of the main goals is to make the device look as inconspicuous as possible. Posted in computer hacks, Security Hacks Tagged A33, Allwinner, Embedded Linux, KiCAD, open hardware, pentesting, WiFiWartР”Р„mong security professionals, a РІР‚Сљdrop boxРІР‚Сњ is a device that can be covertly installed at a target location and phone home over the Internet, providing a back door into what might be an otherwise secure network. Especially ones that are being developed in the open. While many in the hacking and making scene only have a passing interest in the security side of things, we all love our little little Linux boards. The first post about this project got quite a response from Hackaday readers, and for good reason. Whether youРІР‚в„ўve got input on the design, or just want to hang out and watch the WiFiWart get developed, weРІР‚в„ўre sure heРІР‚в„ўd be happy to have you stop by. Want to get in on the fun, or just stay updated as embarks on this epic journey? Perhaps youРІР‚в„ўd be interested in joining the recently formed Open Source Security Hardware Discord server heРІР‚в„ўs spun up. It sounds like the plan is to make use of the vertical real estate within the plastic enclosure of the charger, rather than trying to cram everything into a two dimensional design. Towards the end of the post, he even discusses the ultimate layout of the board, as the one heРІР‚в„ўs currently working on is just a functional prototype and would never actually fit inside of a phone charger. Multiple boards make better use of vertical space. HeРІР‚в„ўs also locked in component selections, such as the RTL8188CUS WiFi module, that were still being contemplated as of our last update. A lot of thought went into how the 1 GB DDR3 RAM would get connected to the A33, which includes a brief overview of how you do automatic trace length matching in KiCad. A bummer to be sure, but thatРІР‚в„ўs what prototypes are for.Р”В®ven though wasnРІР‚в„ўt able to fire the board up, the fact that they even got produced shows just how much progress has been made in a relatively short amount of time. The culprit? Somehow says he mistakenly ordered a 3.3 V regulator even though he had the appropriate 2.5 V model down in the Bill of Materials. Even worse, the precious Magic Smoke was released from the boardРІР‚в„ўs Allwinner A33 ARM SoC when a pin only rated for 2.75 V was inadvertently fed 3.3 V. Now before you get too excited, we should probably say that the prototypes didnРІР‚в„ўt actually work.

But we had a hunch that was tenacious enough see the project through to reality, and now less than two months later, weРІР‚в„ўre happy to report that not only have the first prototype PCBs been assembled, but a community of like minded individuals is being built up around this exciting open source project.

In fact, the whole thing was little more than an idea.

When we last checked in on the WiFiWart, an ambitious project to scratch-build a Linux powered penetration testing drop box small enough to be disguised as a standard phone charger, it was still in the early planning phases.
