MicroTractor Workshop

Maysville, Missouri, USA

Build Yourself. Build Your World.

The MicroTractor workshop is a 3 day event – led by Marcin Jakubowski, founder of Open Source Ecology (OSE) – and Thomas Griffing, OSE Power Cube Lead Developer. The event takes participants hands-on through a complete build of the MicroTractor.

The micro-tractor – the OSE MicroTrac – is a tracked, small-size tractor with a 28 horsepower hydraulic power unit, the Power Cube. The MicroTrac has a quick connect plate and can accept a wide range of implements, from a bucket, backhoe, to a trencher – or it can be used to power other machines – such as a sawmill, brick press, welder, heavy duty lathe, well drilling rig, log splitter, or many others.

Workshop immersion involves concept and practice, and includes crash courses on key elements of fabrication, OSE’s modular design methods, CAD, and documentation. Participants become part of OSE’s design and build process, where we produce open source blueprints for the infrastructures of civilization. This workshop focuses on one of the 50 machines of the Global Village Construction Set – an important utility, agriculture, and construction machine – the MicroTrac.

In 2009, we have built our first prototype of a micro-tractor:

Since then, we learned about the importance of traction, especially in rough conditions. Now, we are building upon our structural Power Cube to build a tracked, stand-behind, multipuropose tractor.

The three day workshop revolves around the structural Power Cube – a 28 horsepower, hydraulic power unit – built in the Power Cube Workshop right before the MicroTrac Workshop. The first day includes crash courses in welding, torching, and other tool use. The workshop features use of OSE’s open source machines – including the open source 20-ton hole puncher, ironworker machine, and CNC Torch Table. This workshop is intended for people interested in immersion, hands-on skills training and practical results. This immersion course may be especially useful to people who would like to master their own machines and tools, such that the machines can last a lifetime.

We will use structural steel tubing construction just like in the Power Cube. Workshop participants will be exposed to modular design – where motors, parts, power units, and other modules can be interchanged between machines. As an example of modularity, we will build a charcoal gasifier after the MicroTractor workshop (not part of this workshop) – so that the MicroTractor – can be run on a locally-produced, carbon-negative biomass resource.

We are inviting those individuals who are interested in building their own MicroTractor – or entrepreneurs interested in starting a business. OSE’s goal is to create open, collaborative, ethical enterprise ecosystems that accelerate innovation towards a better world. We are also inviting dedicated documenters and videographers to participate in documenting the build.

The overall workshop is designed for people interested in transitioning from Zero to Maker, though those with experience will also learn a number of skills. 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.

  • Weekend Workshop (July 13-15): Design, Build, and Get Skills.
  • Documentation Track (July 13-15): Document for replicability.

As a bonus, we are also screening a pre-release of a documentary film on one of OSE’s collaborations – Reversing the Mississippi.

Instructors

hello





  • Marcin Jakubowski was trained as a fusion physicist. He left academia right after finishing his Ph.D. to start a farm – in Missouri. For the last 7 years, he has been working on the Global Village Construction Set – a set of enabling tools and machines for building regenerative infrastructures. Marcin is passionate about creating the Open Source Economy – a new operating system for Earth. See Marcin’s bio.
  • Thomas Griffing has a background in Electrical Engineering, Computer Science, Technical Writing and Hydraulics. He runs a small computer consulting business, instructs Tai Chi classes and also teaches “online” computer classes for a community college in Dallas. He has a farm in East Texas with a shop where he practices permaculture farming, works on projects of interest and sells Power Cube kits, parts and other items. He has also led OSE workshops on fabricating the Power Cube and Micro Power Cube. Tom Griffing is OSE’s Power Cube Lead and has been in Power Cube development since 2011.
