After a full year of development and several months spent in preparation for this campaign, we are thrilled to announce that crowdfunding has begun for Open Game Station—our modular, 8-bit, open hardware gaming platform. We believe it to be a novel development platform, an effective learning tool, and (most importantly) a mighty fun way to play a game. Come have a look!

The FSF is a charity with a worldwide mission to advance software freedom.

The time has come. Inkplate 6 has begun shipping, and many of you have already received yours. Which makes this a good time for us to provide some guidance on how to set up your Inkplate 6 and get started working with it. We made everything is as simple as we could, so the setup process itself shouldn't take more than five minutes. This update walks you through those five minutes. It also includes information about: our library of examples, Peripheral Mode, battery power, and open source documentation

Recent studies have suggested various side-channel attacks for eavesdropping sound by analyzing the side effects of sound waves on nearby objects (e.g., a bag of chips and window) and devices (e.g., motion sensors). These methods pose a great threat to privacy, however they are limited in one of the

The Arduino Uno board has over 20 pins that you can use for many different applications. In this post I’ll give you a complete and practical overview of the main Arduino Uno pins. If you’re starting with Arduino, or if you’re already a software developer and want to learn more about the bridge between software ... Read more

The Apollo Guidance Computer (AGC) is a digital computer produced for the Apollo program that was installed on board each Apollo command module (CM) and Apollo Lunar Module (LM). The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft.The AGC has a 16-bit word length, with 15 data bits and one parity bit. Most of the software on the AGC is stored in a special read-only memory known as core rope memory, fashioned by weaving wires through and around magnetic cores, though a small amount of read/write core memory is available. Astronauts communicated with the AGC using a numeric display and keyboard called the DSKY (for "display and keyboard", pronounced "DIS-kee"). The AGC and its DSKY user interface were developed in the early 1960s for the Apollo program by the MIT Instrumentation Laboratory and first flew in 1966. The AGC was the first silicon integrated circuit based computer. The computer's performance was comparable to the first generation of home computers from the late 1970s, such as the Apple II, TRS-80, and Commodore PET. Operation Astronauts manually...

The CrossWire Bible Society is an organization with the purpose to sponser and provide a place for engineers and others to come and collaborate on free, open-source projects aimed at furthing the Kingdom of our God. We are also a resource pool to other Bible societies that can't afford-- or don't feel it's their place-- to maintain a quality programming staff in house. We provide them with a number of tools that assist them with reaching their domain with Christ. CrossWire is a non-income organization, which means that not only do we offer our services for free, but we also do not solicit donations to exist. We exist because we, as a community come together and offer our services and time freely.
