CEB Press Workshop

[metaslider id=7911]

April 25-27 or 25-28 (1, 3 & 4 day options*)

Factor e Farm – Maysville MO, USA

Build Yourself. Build Your World.

This 3 or 4-day workshop – led by Marcin Jakubowski, founder of Open Source Ecology – shows how Extreme Manufacturing techniques are used to build a complete Compressed Earth Brick (CEB) Press in One Day. Workshop immersion involves concept and practice, and includes crash courses on key elements of design, fabrication, CAD, microcontrollers, hydraulics, open documentation, and open enterprise models. We are inviting entrepreneurs interested in creating Distributive Enterprise : radically open, libre, collaborative, ethical enterprise ecosystems that accelerate innovation. We are also inviting dedicated documentors to participate in a Book Sprint – where we are guided from zero to a complete, published manual and book – in 4 days. The overall workshop is designed for people interested in transitioning from Zero to Maker.

* An extra day option exists for those interested in creating enterprises around the CEB Press. Possible enterprises include both manufacturing of CEB Presses and building of housing. You are also welcome to attend a single day of the workshop but should be aware that if you miss April 25 you may not be able to perform build tasks that require special skills. We are also offering a dedicated documentation track – where you do not participate in the build, but participate in producing a publishable, easily updateable, well-formatted manual on the CEB Press using Book Sprint techniques. If you can’t attend the workshop because you need financial assistance, email us and we will put you on the waiting list. We will select you if a Sponsor provides funding.

  • Weekend Workshop (April 25-27): Design, Build, and Get Skills..
  • Enterprise Track (April 25-28): Design, Build, Get Skills, and explore Distributive Enterprise.
  • Book Sprint Track (April 25-28): Document for viral replication.
