Currently, we are still working on getting our first order of The Liberator high performance, open source, Compressed Earth Brick (CEB) press out the door. We are now upgrading the automatic controls.
We have published a technical paper on the automation problem statement. We are managing the project at the Open+Pario project management site, where you can download a copy of this paper under the Documents tab. The paper outlines the technical issues surrounding effective automation, based on our previous results. It provides the necessary background if you want to collaborate on the project or build upon it – in the name of open source development. Here is the abstract:
Abstract: There are several considerations for the successful implementation of automatic controls on The Liberator*, the world’s first, high performance, open source, Compressed Earth Brick (CEB) press. Considerations include: (1), brick production work flow design; (2), simplicity of control logic; (3), brick thickness adjustability and uniformity; (4), modular, lifetime design; (5), performance optimization; (6), cost, (7), interchangeability of hydraulic power units1; (8) open source standards; and (9), simple user interface. This technical paper documents these issues for the development team and the greater community as part of the open source process. The greater context for this work is promoting the creation of post-scarcity, resilient communities. This paper promotes the greater context by contributing to the solution of one of the most basic needs of humanity – housing – under the assumption that earth construction is the most robust and most widely-used method of housing worldwide2. Revisions of this work are found at Open+Pario3.
1The Liberator is designed to be powered by any external, hydraulic power source, such as Power Cube* or another tractor or skid loader*. This is part of the modular design strategy of OSE and the Global Village Construction Set* (GVCS).
2See Earth Construction*. Regarding the extent of use of earth construction, the industrialized world is presently lagging behind the developing world.
