Hardware Hackers Create a Modular Motherboard | Gadget Lab An ambitious group of hardware hackers have taken the fundamental building blocks of computing and turned them inside out in an attempt to make PCs significantly more efficient. The group has created a motherboard prototype that uses separate modules, each of which has its own processor, memory and storage. Each square cell in this design serves as a mini-motherboard and network node; the cells can allocate power and decide to accept or reject incoming transmissions and programs independently. Together, they form a networked cluster with significantly greater power than the individual modules. The design, called the Illuminato X Machina, is vastly different from the separate processor,memory and storage components that govern computers today. “We are taking everything that goes into motherboard now and chopping it up,” says David Ackley, associate professor of computer science at the University of New Mexico and one of the contributors to the project. Norair agrees.
Elektronika.ba RepRap RepRap is humanity's first general-purpose self-replicating manufacturing machine. RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. RepRap was voted the most significant 3D-printed object in 2017. RepRap state-of-the-art when this page was last updated (June 2017) is well represented by the RepRap Snappy, RepRap Dollo and the RepRap Generation 7 Electronics.
» Intro JeeLabs This is a daily weblog about my experiments based on the mix of electronics and computing called “Physical Computing”. I’m building little “sensor nodes” to measure electricity use, temperature, light, etc. which they transmit wirelessly to one of the central computers in the house. One goal is to better understand how we’re using electricity and how we’re heating the home, so that we can try to improve on it. There is used to be one new post every day at midnight. Update – as of November 2014, I’m pleased to announce that the weblog has been resumed, but with a slightly different setup and frequency. There are three other websites associated with this weblog: the Café is a wiki where all documentation and reference material is being collectedthe Forum area is an open discussion forum to ask, discuss, and exchange ideasthis Shop offers some of my projects, for those interested in kits or ready-made stuff Explore! Oh, and enjoy your visit, -jcw
Linux Fund: OGD1 Available for Grant Application and Purchase! The Open Graphics Device v1 is an open hardware prototyping platform based on a fully programmable FPGA semiconductor. The OGD1 features dual DVI-I outputs and 100-pin IDC connector for exceptional video and I/O flexibility. The Open Graphics Project designed and maintains the OGD1, and all of its schematics are available under an open source license. Linux Fund has build twenty-five OGD1's, ten of which will be given to developers who are committed to advancing the platform and twelve of which will be sold to cover the manufacturing costs. Developers: How to apply to receive an OGD1 The goal of this developer program is two-fold: To guarantee solid open source operating system driver support and to stimulate innovative uses of this unique computing platform. Interested developers are invited to write ogd1@linuxfund.org with a description of their background, technical qualifications and how they would use an OGD1. Limit one per customer.

Welcome Hacking the Samsung CLP-315 Laser Printer | Hello World! I am the happy owner of a Samsung CLP-315 laser printer. It is a fantastic printer for the price. Things were going great until it came time to replace the toner. A “journey”? How Stuff Works Since I last purchased a laser printer (my circa 2001 LaserJet 1200 is still kicking) the industry has changed. Why does this matter, you ask? This causes two problems. Unsurprisingly, I am not the first person to try to address this problem. Sniffing After doing some homework, I decided to try watching the I²C traffic with a logic analyzer to see what memory locations were getting updated on the EEPROM after each print. I wrote an Arduino sketch to dump the entire memory of the EEPROM to the serial port. The next thing I did was print off the printer’s “Configuration Report”. Now I had a list of memory locations that (I assumed) stored the page counts. I was able to successfully write zeros to all of the incrementing memory locations. The Discovery So, the idea struck me.

Embedded board manufacturers and dealers Difficult to choose between manufacturers of embedded system boards supporting Linux and other Free Software operating systems? There are so many of them now… To help you find the best hardware solution for your system, we are keeping a list of suppliers making attractive products. Here are the conditions to be on the list: Offer attractive and competitive productsAt least one products supported (at least partially) in the official versions of Free Software operating systems (Linux, eCos, NetBSD…). This is a rather strong requirement, but only such products bring a guarantee for long term community support, making it much easier to develop and maintain embedded systems. Companies and organizations are listed by alphabetical order, mentioning the country where their headquarters are. Organizations Contributing to this page Don’t hesitate to contact us to let us know about other suppliers, or to report websites which still are on our list but no longer match our criteria.
