J-core is a clean-room open source processor and SOC design using the SuperH instruction set, implemented in VHDL and available royalty and patent free under a BSD license.
The rest of this page explains how to compile and install a "bitstream" file to implement this processor in a cheap (about $50) FPGA board, then how to build Linux for that board and boot it to a shell prompt.
2018/12/11: a homebrew 6502-based microcomputer. I have a lot of ideas for features I’d like, but before I make too many crazy decisions I’d like to solidify my understanding of the processor I’m building the whole system around.
2018/09/19: Just after the California bill was introduced, the farm equipment manufacturers started circulating a flyer titled “Manufacturers and Dealers Support Commonsense Repair Solutions.” In that document, they promised to provide manuals, guides, and other information by model year 2021. But the flyer insisted upon a distinction between a right to repair a vehicle and a right to modify software, a distinction that gets murky when software controls all of a tractor’s operations.
As Jason Koebler of Motherboard reported, that flyer is strikingly similar—in some cases, identical word-for-word—to the agreement the Farm Bureau just brokered. The flyer and the agreement list the same four restrictions:
No resetting immobilizer systems.
No reprogramming electronic control units or engine control modules.
No changing equipment or engine settings that might negatively affect emissions or safety.
No downloading or accessing the source code of any proprietary embedded software.
These restrictions are enormous. If car mechanics couldn’t reprogram car computers, a good portion of modern repairs just wouldn’t be possible.
2016/11/16: overview of the main risks and opportunities of the Digital DIY phenomenon, and of how the H2020 DiDIY project has studied it
Imagine printing out a paper computer and tearing off a corner to share - ink laced with silver nanoparticles could make it a reality, to the joy of hobbyists
A fast-growing open hardware movement is creating ingenious versions of all sorts of technologies, and freely sharing them through social media. CERN is home to some of the largest and most complex scientific equipment on the planet. Yet back in March, scientists gathered there for a conference about DIY laboratory tools. Scientists in poorly funded... Continue reading ...
After two generations of Moto Mods, Lenovo's wild-but not wildly successful-smartphone concept is at a crossroads.
Peer production has emerged as a new and relevant way of organising the work of distributed and autonomous individuals in the production and distribution of digital content. Increasingly, the adoption of peer production is taking place not only in the development of digital and immaterial content, but also in the design, manufacturing and distribution of physical goods. Furthermore, Open Design and Open Hardware projects are developed, discussed, manufactured and distributed thanks to digital fabrication technologies, digital communication technologies, advanced funding initiatives (like crowdfunding platforms and hardware incubators) and globally integrated supply chains. This new systemic dimension of work is possible, among other factors, thanks to local facilities like Fab Labs, Makerspaces and Hackerspaces (that can be generally called Maker laboratories), where individuals can gather and form communities with other people, designing and manufacturing together. Generally, these people are referred to as Makers and, while their existence is still an emergent phenomenon, it is widely acknowledged that they could exemplify a new modality of work. We investigated the knowledge, values and working dimensions of Makers in Italy with the Makers' Inquiry, a survey that focused on Makers, Indie Designers and managers of Maker laboratories. This research generated a first overview of the phenomenon in Italy, improving the knowledge of the profiles of Makers; an important step because Makers are usually defined in a very broad way. Furthermore, we investigated their profiles regarding their values and motivations, in order to understand how much Makers engage in peer production or in traditional businesses and whether their working condition is sustainable or not. Finally, we compared these profiles with data regarding traditional designers and businesses and the national context. Given the recent nature of the Maker movement, the focus of this article is on providing a first overview of the phenomenon in Italy with an exploratory analysis and with comparison with existing related literature or national data, rather than contextualising the Maker movement in sociological and political contributions. Far from happening in a void, Italian Makers have a strong relationship with their localities and established industry. Therefore, this is a recent evolution, where Makers work with a broader palette of projects and strategies: With both non-commercial and commercial activities, both peer production and traditional approaches. The activity of making is still a secondary working activity that partially covers the Makers' income, who are mostly self-employed working at home, in a craft workshop or in a Fab Lab in self-funded or non-commercial initiatives, where technology is not the only critical issue. As a conclusion, we identified current patterns in the working condition of Italian Makers. The data gathered shows some interesting information that, however, could be applicable only to an Italian context. Nevertheless, the survey could be a starting point to compare the same phenomenon in different countries. Therefore, we released the survey files, software and data as open source in order to facilitate the adoption, modification, verification and replication of the survey.
We are happy to announce that we have kicked off the first REMODEL test run with Danish manufacturing company Th195188rmer Tools' 3D print-unit TwentySeven. The test run with help us uncover the necessary steps for manufacturing companies to be able to develop new business models based on open source principles.
Local Motors is a ground mobility company focused on shaping the future for the better. Founded in 2007 with a belief in open collaboration and co-creation, Local Motors began low volume vehicle manufacturing of open-source designs using multiple micro-factories.
This project will involve a quantitative and qualitative evaluation of “designed global, manufactured local” (DGML) products from an ecological economics perspective. We will conduct a life-cycle assessment (LCA) of 2-3 DGML technological solutions (e.g. a house, an open source 3D printer, a wireless data transmission, a prosthetic hand). LCA will include an assessment of the energy and material uses of the product from cradle to grave, including during its use and operation. This will be compared against the life-cycle of a conventional technology. Different states will be distinguished, such as extraction of materials, production, transport, disposal of equipment, and the environmental impacts of each assessed. For the assessment, the CML 2 baseline 2000 will be used. Qualitative assessment will be based on observations of the application of the technology, interviews and focus groups such as farmers or makers. Technologies will be compared according to three key criteria for sustainability: (a) “autonomy”; (b) “resilience”; (c) “ecological adaptability”. The end result will be an actual comparison of the environmental and social costs and benefits of the applied technologies, as well as the development of a prototype approach for an ecological-economic evaluation of any DGML solution. Last but not least, this task will provide research and policy proposals in relation to the environmental performance of DGML products, and their implications in terms of resource and energy use, as well as their sustainability in a possible future of resource scarcity and altered environmental conditions.
Crowd Supply (previously) is an extremely effective platform for funding open source hardware development, boasting twice the success-rate of Kickstarter and Indiegogo; it is also the birthplace of the proclamation of user rights, an outstanding document that lays out the rights of users to explore their hardware, use it independent of any subscription, use it
Showerloop is a water filtration and purification system that recycles shower water in real time allowing you to shower with hot water for a long time but only use 10 liters of water per shower (normal shower = ~6-10l/min) and a fraction of the energy (around one tenth) compared to a normal shower. The device can be installed inside or outside of a shower stall or bathtub.
