Construction documentation for the Null 2 Linux-powered handheld console.
Want to build a RasPi cluster shaped like an old-school Cray supercomputer? 'course you do! You can find the greyprints and see how to assemble it here.
A stackable simple-to-build single board computer storage that is open-source and modular which is made from sustainable materials. This repository contains the official production files that can be used for laser cutting and 3D printing.

The Neoram module is a replica of the Georam extension with battery backup by Nicolas Welte (X1541). This was created in the summer of 2006 and over time became the first small series. The picture (left) shows the first fully equipped version. The maximum expansion with 2MB SRAM expands the memory of the C64 many times over and gives it completely new possibilities.
In the past, the predecessor Georam, as the name suggests, was specially developed for Geos. Geos users can hardly be found today. But that doesn't make the extension useless.
The programming is identical to the Georam and in principle very simple. A 16kB page is selected via banking, from which a 256-byte window is always displayed.
dialup.world is (currently) a three-line dial-up ISP!
At Futel, we believe in the preservation of public telephone hardware as a means of providing access to the agora for everybody, and toward that goal we are privileged to provide free telephone calls, voicemail, and telephone-mediated services. We do not judge the motivations of our users, or who they choose to call; if they don’t have someone to call, we can provide a presence on the other end. Denial of telephony services has long been a tactic used against undesirable populations, and our devices will counteract that. But more importantly, we will help to establish a new era of communication, one in which reaching out is not only desirable, but mandatory.
Based in Portland, OR.

An open source 3d scanner built around multiple RasPi single board computers and an equal number of digital cameras (between 3 and 5, inclusive). This is a fairly complex build, definitely not for beginners.
An organization of hobbyists who run an alternative DNS network, also provides access to domains not administered by ICANN.
The Polyform Project is a group of experienced licensing lawyers and technologists developing simple, standardized, plain-language software source code licenses. Polyform aims to fill gaps in the menu of standardized software licenses, like non-commercial, trial, and small-business-only terms.
They're basically trying to do a modular Creative Commons-like license, but for software.
The BASIC Engine is a very low-cost single-board home computer with advanced 2D color graphics and sound capabilities, roughly comparable to late-1980s or early-1990s computers and video game consoles. It can be built at home without special skills or tools and using readily available components for under 10 Euros in parts, or mass-produced for even less.
An Open Streetmap effort to build maps of places that are underserved. Humanitarian effort to fill in the blanks where companies don't or won't reach.
How to use conductive ink and a capacitative interface kit to make a touch sensitive DJ controller that works with Linux.
How to build your own non-destructive book scanner to archive texts. Total cost: less than $300us. It's pretty speedy, too - on the order of 1200 pages per hour.
The DIYLILCNC is a fully functional, open source 3-axis CNC that you can build with basic tools and parts that can be locally sourced. The idea is that you develop a 3D design in a CAD application, put feedstock into the CNC, and print your design to it, and it cuts and grinds away everything but what your design is supposed to be. Total cost of construction is about $700us. You can download the plans and DXF template files from the website for free (they have a CC-BY-SA license).
Where and how to download mirrors of Wikipedia (or any of the Wikimedia projects, for that matter). You can put the copies up someplace to set up mirrors, put up local copies, archive them, give them to people, set up your own instance, use it for research...
lowRISC is an open source RISC-based system-on-a-chip and accompanying development board. Based on the 64-bit RISC-V instruction set and architecture. Designed to be a fully open source and very low cost general purpose computer.
CellF is the world’s first neural synthesiser. Its “brain” is made of biological neural networks that grow in a Petri dish and controls in real time it’s “body” that is made of an array of analogue modular synthesizers that work in synergy with it and play with human musicians. It is a completely autonomous instrument that consists of a neural network that is bio-engineered from my own cells that control a custom-built synthesizer. There is no programming or computers involved, only biological matter and analogue circuits; a ‘wet-analogue’ instrument.
