How to Make Everything Ourselves: Open Modular Hardware

How to Make Everything Ourselves: Open Modular Hardware
A modular system unites the advantages of standardisation (as parts can be produced cheaply in large amounts) with the advantages of customisation (since a large diversity of unique objects can be made with relatively few parts). Modularity can be found to a greater or lesser extent in many products (like bicycles and computers) and systems (like trains and logistics), but the best examples of modular systems are toys: LEGO, Meccano, and Erector (which is now the brand name of Meccano in the US). LEGO, Meccano and Erector are composed of relatively few elementary building blocks, which can be used to build various objects. The parts can then be disassembled and re-used to build something completely different. Apart from the elementary buildings blocks, these manufacturers have produced many more specific building blocks, which are less versatile, but further increase customisation possibilities.

Got a Kinect and a laptop? Get ready to 3D print Volumental's vision is to be able to 3D print more or less anything you can see Image Gallery (7 images) Scanning and 3D printing an object could become much simpler if 3D printing company Volumental is successful in crowdfunding the development of a web app which would allow users to scan and print 3D objects using nothing more than a Kinect sensor and a web browser. View all Though the company already has a web service that allows people to upload scanned 3D models, Volumental says that it needs to refine an app which is better able to differentiate a thing (toys, pets, family members are among the suggestions) from its surroundings in order to be able to print the object in isolation. If funded, the app raises the exciting prospect of being able to scan more or less anything. Volumental is aiming to develop the app inside of three months. Though that sounds ambitious, Volumental is not a beginner in the field of 3D scanning. You can see the team's campaign video below. About the Author

E3D Unveils Most Affordable 3D Printer Hotend Yet, The E3D Lite6 — Priced Under $32 When it comes to 3D printers, one of the most important, as well as expensive components on any FFF or FDM machine is the hotend. After all, the hotend is what transforms your filament into the molten hot plastic as it is released onto the build platform. A faulty hotend equates to terrible print results. When it comes to hotend manufacturing, there are few companies, if any, who have garnered the respect in the industry as E3D has. Typically a hotend will run anywhere from around $45 all the way up to over $175, depending on its capabilities. “We designed Lite6 to be a low cost hotend for robust easy printing for everyday filaments, for temperatures up to 240 degrees C and moderate printing speeds,” explained Sanjay Mortimer, E3D Director and R&D/Community Manager. The company likes to think of the Lite6 as the V6’s little brother, with modest capability, and an incredibly affordable price. The Lite6 hotend is, as far as we are aware, the most affordable hotend currently on the market.

Register © CommaFeed - Sources on GitHub - REST API documentation HackerspaceWiki The maker movement isn’t just for hackers anymore “I’ve always done a certain amount of work with my hands, but my whole career was in software.” Rich Pekelney (pictured above) is standing in front of one of many mammoth machines in San Francisco’s TechShop, a DIY paradise full of industrial equipment for makers of all kinds. The space is intimidating at first glance. Loud mechanisms tower and sprawl around the workshop’s several stories; people in welding masks and heavy protective gloves quietly bustle from one corner to another. But after a few minutes in the shop, its aura of mystery quickly disappears. At TechShop’s San Francisco location, a $125 monthly membership fee gets you access to more than $1 million dollars of industrial-grade machinery, industry-standard design software for 2D and 3D projects, unlimited workshop hours, and coaching from experts in given techniques and materials. Pekelney came here at first because, like so many other TechShop members, he needed to make something that couldn’t be bought. Making’s roots

3datdv | Blog from the 3D at DV Challenge team De vrije markt versmoort het vrije woord Vandaag is het World Press Freedom Day, een dag die in België nooit werd gevierd. Toen in 1993 de Verenigde Naties 3 mei uitriepen tot internationale dag van de persvrijheid hadden ze vooral landen in gedachten waar de staat het vrije woord brutaal verdrukte. Maar dit jaar trekt PEN Vlaanderen aan de alarmbel: 3 mei moet helaas ook hier gevierd worden. Want wij, schrijvers van Vlaanderen, zijn ernstig bezorgd over de kwaliteit van de journalistiek. De reden is eenvoudig. Tekenend in dat opzicht is dat Offshore-leaks, de grootste journalistieke onthulling in jaren, niet in de commerciële media maar in de nonprofit-sector ontstond. Bijna alle massamedia in Vlaanderen (kranten, radiostations, televisiezenders) zijn commerciële media: hun primaire logica is die van de kijkcijfers, de verkoopsaantallen, de luisterdichtheid of de unieke geregistreerde gebruikers. Voor wat het waard is: in de Press Freedom Index van Reporters Zonder Grenzen zakte België dit jaar naar de 21ste plaats.

Engineering ToolBox LEGObot 3D Printer Ever since I saw the first makerbot, I have been obsessed with 3D printing, I am an engineering student and I don't have an extra $800-$2500, and have been doing my best to create one out of what I have on hand. I tried using arduino with easy drivers, and parallel port, but neither one gave results, I always needed a tool or part that I couldn't get. So I pulled out my old box of legos and started building. This is a project I have been working on for the past year, it prints in hot glue and is made almost completely out of legos. Its design is roughly based on the first version of the makerbot. While hot-glue works, its very rubbery and doesn't have many practical uses, if only one or 2 layers are printed then it will stick to glass to make window stickers, but its not sturdy or rigid, I will be experimenting with printing using wax and heat-melting resins in the future. If you liked this and want to see more, please vote for it in the 3d printing and lego contests! Thanks, Matt

Cults ・ Buy and sell 3D models for 3D Printer Sacred Economics: Chapter 17, Summary and Roadmap | Sacred Economics | Charles Eisenstein The following chapter is from Sacred Economics: Money, Gift, and Society in the Age of Transition, available from EVOLVER EDITIONS/North Atlantic Books. Return to the Sacred Economics content page here. First they ignore you, then they laugh at you, then they fight you, then you win. Before I explore more deeply the shift in personal economic thinking and practice that is part of sacred economy, I will summarize its key macroeconomic elements. The transition I map out is evolutionary. The reader may notice that, except where they are off the map entirely, most of these developments fall on the left side of the political spectrum. 1. Motivation: Negative interest on reserves, and a physical currency that loses value with time, reverses the effects of interest. Transition and policy: We were on the brink of a transition to decaying currency in 2009, as central banks pushed interbank interest rates to near zero and flirted with breaching the zero lower bound. 2. 3. 4. 5. 6. 7.

Building the open source laptop: How one engineer turned the geek fantasy to reality For decades anyone buying a new computer did so in the knowledge that within a few years it would be overtaken by a much faster machine. Driving this rapid evolution has been Moore's Law – which has allowed the building block of information processing, the transistor – to be packed in greater numbers onto ever smaller computer chips. But Moore's Law is slowing, as various engineering challenges have limited the rate at which transistors can be added to processors and this throttling back will increasingly provide an opening for the little guys to make their mark in the hardware world. That's the theory of Andrew 'Bunnie' Huang, a hardware engineer who is demonstrating what is possible for a small hardware outfit to do by designing and building his own laptop. This machine isn't your standard corporate-issue device, but a machine that from top to bottom is open in its design. Every component in Huang's laptop, known as the Novena, is open. But Huang doesn't see himself as a maverick. Extras:
