Power Cube Workshop

July 4-6, 2014

Maysville, Missouri, USA

Build Yourself. Build Your World.

This 3 day workshop – led by Marcin Jakubowski, founder of Open Source Ecology (OSE) – and Thomas Griffing, OSE’s Lead Power Cube Developer, shows how Extreme Manufacturing techniques are used to build a complete Power Cube and Micro Power Cube (µPC) – in One Day.

This is the first OSE workshop where participants can purchase and build µPC kits (limit 12 kit builds / workshop).

Workshop immersion involves concept and practice, and includes crash courses on key elements of hydraulic power unit design, fabrication, CAD, open source hardware documentation, and open enterprise models. As a participant, you will be helping us to improve the machine and produce documentation – to realize viral replicability of our libre hardware.

The three day workshop includes a one day build of the Micro Power Cube – a 2 horsepower, electric-powered hydraulic power unit of one cubic foot in size, and under $300 in materials cost. We will also build a full-sized, 27 hp, gas-powered hydraulic power unit. Most of the build will involve welding, followed by assembly – and involves producing parts for the assembly. This workshop is intended for people interested in immersion, hands-on training for practical results.

We are inviting entrepreneurs interested in creating Distributive Enterprise based on open hardware: radically open, libre, collaborative, ethical enterprise ecosystems that accelerate innovation. We are also inviting dedicated documentors to participate in documenting the build.

The overall workshop is designed for people interested in transitioning from Zero to Maker. Can’t weld? We’ll give you a crash course. This course assumes no prior skills outside of general body awareness. Some people will be given documentation tasks if appropriate.

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 (July 4-6): Design, Build, and Get Skills.
  • Documentation Track (July 4-6): Document for viral replication.
