CNC Machine Shop | Custom Waterjet, Plasma, Laser Cutting | eMachineShop.com Welcome 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.

Processing.org How to Implement Embedded Ethernet We need embedded systems inside devices, particularly the so-called intelligent devices, to communicate with a command/control/administrative center. Typical such situations could be a remote security camera that can send you video clips when queried, an embedded system that can send status when checked through a web browser or a vending machine that is capable of sending an email when service is required. Benefits of connecting such embedded systems to the net are easy monitoring and control that can be done through a simple and existing web browser. Most often networking infrastructure is already available in the form of 10/100 Mbps Ethernet networking through Cat 5 cabling. The interface that is required is an Ethernet interface to hook onto such an infrastructure. The interface needs to be low cost and easy to implement so that only a minimal additional cost is involved. Hardware required is a suitable Ethernet controller and an Ethernet connector.

Ingeniería Electrónica y Proyectos PICmicro® bildr 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.

Contactless card reader IC handles multiple protocols NXP Semiconductors has launched the CLRC663, the first member of a new generation of high-performance proximity contactless reader ICs. It combines robust multi-protocol support with the highest RF output power and patented low-power card detection technology. The CLRC663 is targeted at a wide variety of use scenarios, including banking, e-government, transport and mobile payment. Supporting all 13.56-MHz contactless standards, NXP’s new reader IC is compatible with all established smart card, smart tag and smart label technologies, including NFC Forum tag types and Mifare products. It ensures best-in-class interoperability with smart cards, electronic documents and NFC-enabled phones based on NXP technology. [via] Contactless card reader IC handles multiple protocols - [Link]
