TechShop is America's 1st Nationwide Open-Access Public Workshop -- What Do You Want To Make at TechShop? Cooperative In short, a coop can be defined as "a jointly owned enterprise engaging in the production or distribution of goods or the supplying of services, operated by its members for their mutual benefit, typically organized by consumers or farmers."[4] Cooperative businesses are typically more economically resilient than many other forms of enterprise, with twice the number of co-operatives (80%) surviving their first five years compared with other business ownership models (41%).[5] Cooperatives frequently have social goals which they aim to accomplish by investing a proportion of trading profits back into their communities. As an example of this, in 2013, retail co-operatives in the UK invested 6.9% of their pre-tax profits in the communities in which they trade as compared with 2.4% for other rival supermarkets.[6] The International Co-operative Alliance was the first international association formed by the cooperative movement. It includes the World Council of Credit Unions. Origins[edit]
Open Design Now | Why design cannot remain exclusive A newbie's guide to UAVs What is an amateur UAV? An Unmanned Aerial Vehicle (UAV) is an aircraft that has the capability of autonomous flight, without a pilot in control. Amateur UAVs are non-military and non-commercial. What do I need to make one? ---1) An RC plane, muticopter (quadcopter/hexacopter/tricopter, etc) or helicopter. What does DIY Drones have to offer? The DIY Drones community has created the world's first "universal autopilots", ArduPilot Mega (APM) and its next-generation big brother, Pixhawk. A full setup consists of: Pixhawk autopilot: The electronics, including twin processors, gyros, accelerometers, pressure sensors, GPS and more (shown at right). You can buy Ready-to-Fly UAVs (both planes and multicopters) from 3D Robotics: Last but not least is flight safety. Also, here's the FAA's official word on what's legal and what's not.
Hackteria.org Gear template generator This free online gear template generator is designed for making scale accurate paper gear templates which you can glue onto wood and then cut out with a bandsaw. I recommend printing the gears with an ink jet printer. Even cheap ink jet printers print very scale accurate but Not all laser printers are accurate. Getting the printout to scale correctly, avoiding cropping Different browsers print at different scales depending on browser type and printer configuration. Use an ink jet printer I recommend using an ink jet printer. Printing the gear templates To print the gear template, use the 'Print' button, instead of printing the web page from the browser. The gear generator program that I created and sell doesn't need the scale calibration, and can paginate across many pages for larger gears. Some notes about gear design and this gear template generator This gear template generator generates shapes for involute spur gears. The gear tooth generation is not perfect. Any questions?

OpenCola (drink) OpenCola is a brand of open-source cola, where the instructions for making it are freely available and modifiable. Anybody can make the drink, and anyone can modify and improve on the recipe as long as they, too, license their recipe under the GNU General Public License. Since recipes are, by themselves, not copyrightable, the legal basis for this is untested.[1] The flavouring formula for OpenCola is:[2][3] Ingredients of OpenCola 2.36 kg plain granulated white table sugar2.28 L water30.0 mL caramel color17.5 mL (3.50 tsp.) 75% phosphoric acid or citric acid10.0 mL (2.00 tsp.) flavouring formula2.50 mL (0.50 tsp.) caffeine (optional)[2][3] After mixing up the concentrate to the prescribed recipe (including all recommended safety precautions – see links), the syrup is diluted 5:1 with ("preferably sodium-free") soda water to make the finished drink; at this dilution, the above combination of ingredients will yield approximately 24 litres of OpenCola.
