We are seeking submissions for talks, posters, and demos from individuals and groups working with open hardware and related areas. Submissions are due by May 31, 2012 BY 11:59pm (EST). Notification of accepted proposals will happen by July 8th, 2012.

Rolamentos em Plástico, para o que precisarem:

Hardware Store Plastic Roller Bearings

Moldes para injecção, impressos em 3D:

Molds directly from a 3d printer to an injection molder

In this Instructable I will document the process of an experiment i have been working on to test fairly low pressure injection molding using 3d printed molds.

You should be able to find everything you need for this project laying around your house:

-An initial concept and the ability to execute it in a digital format capable of exporting to a 3d printer

-a high res 3d printer

-an injection molder

-a handful of pelletized thermoplastic

Eis o Fogão-Foguete, um Fogão, que aproveita a Lenha que se farta, e ainda por cima, deita pouco ou nenhum fumo!

Fabricating a Heavy-Duty Rocket Stove

Rocket stoves are small efficient stoves that can produce a hot flame with only a few small pieces of wood. The reason it is called a rocket stove is because when wood is added to the fire the flames create an internal draft. As the draft is created, the fire begins to produce a jet of fire coming through the stove pipe. The stove flame eventually becomes so hot that it produces very little smoke. The stove should be able to produce a hot continuous flame that will lick the bottom surface of a pot or pan placed on top of the stove.
