=Introduction=

The Liberator is OSE's automatic, high throughput (up to 16 bricks per minute) Compressed Eearth Brick Press. It is named The Liberator because it is intended to free people from the single highest cost of living - housing. See [[Cost of Living]] and [[GVCS Naming Convention]].
==Status==
Prototype IV built in a [[Collaborative Production Run]].
Build and use the '''CEB Press''' to make [[Compressed Earth Blocks]] to make all sorts of structures!

'''Code Functions'''

*Sensor signal strength monitor
*Sensor latching monitor
*Cylinder full motion-sensed cycling
*Continuous brick pressing

'''Code Features'''

*Boolean menu and important variable values at beginning of code!
*Motion-time-calculated compression and release durations
*Serial write feedback during testing and operation!
*Multi-sample-averaged sensor signal processing!
*Proper motion ordering for minimum-trouble operation!

----

*Avoid code uploading frustration! [http://opensourceecology.org/wiki/CEB_Press/Manufacturing_Instructions/Code_Upload How to upload code to the Arduino microcontroller]

*Avoid excessive hydraulic pressure! Make sure you have a correctly installed pressure relief valve on your hydraulic circuit. Start testing the CEB Press with a low pressure setting on the pressure relief valve.

*Avoid hydraulic fluid leaks and non-motion! Check that all hydraulic connections are tightened/connected and theoretically leak-free.

*Avoid premature sensor latching! Check that the sensors are mounted parallel to the magnets. Sensor should be not too close but not too far from magnets

*Make sure that the middle primary magnet is passed by the end of the primary cylinder's compression motion

=Overview=
[[File:Liberator_bricks.JPG|right|400px|thumb|Bricks pressed on [[The Liberator]]]]
The '''"Liberator" Compressed Earth Block Press''' is a machine that makes compressed earth blocks ('''CEB'''s).

The [[CEB Press]] takes earth/dirt/soil and compresses it tightly to make solid blocks useful for building. Compressed earth blocks have many advantages as a building material: by making the building materials from the readily available dirt on the building site, they eliminate the need to transport bricks from elsewhere, reducing financial cost and environmental impact. Compressed earth blocks are very strong and insulate well against both heat and sound, making for very energy-efficient building (especially combined with the energy savings from not needing to transport them from offsite). Best of all, the material they use is already on-site and does not need to be purchased -- quite literally, dirt-cheap! See the wiki page on [[Compressed Earth Blocks]] and the [[:Category:CEB|CEB category]] for more details on building using CEBs.

The Liberator has been fully designed and tested by the [[Open Source Ecology]] team. Because the Liberator is an open source technology, you can freely download instructions to build your own from materials you can obtain yourself, or contact ''opensourceecology[at]gmail[dot]com'' to buy a kit or a finished machine.

Building a machine yourself might seem intimidating, but every step of the process is fully documented and the OSE community is available on our [http://forum.opensourceecology.org/ discussion forums] if you need help, advice, or a little hand-holding.

Using the CEB Press, two people can build a 6 foot high (1.83m) round wall, 20 feet (6.1m) in diameter, 1 foot (30cm) thick, in one 8 hour day, though construction time will vary somewhat depending on preparation time, what equipment is available (tractor to prepare the ground and move the blocks where they need to go), the quality of the soil, and other factors. The bigger the block size, the faster a wall can be erected, but at the cost of heavier blocks that are more of a strain to work with. Blocks from ''The Liberator'' average 25 pounds (11.3kg).

See [[CEB Design]] for more information.

[[Image:creationreplication.jpg|thumb|James Slades' first independent replication of the CEB Press in process as of Sep. 2, 2011. Welding the soil loading drawer.]]
*Currently the CEB is at product release status and is being actively manufactured at Factor e Farm and in Texas. The presses will be used heavily as a part of the [[Factor e Farm Infrastructure Buildout 2011]].
*The CEB documentation is being actively upgraded to meet [[Fabrication_Procedure_Standards]] with the goal of serving as a reference implementation for [[GVCS]] documentation.
*Eventually the [[CNC Torch Table|torch table]] will be used to automate the fabrication of the CEB machine, reducing fabrication time by an estimated 20 hours and, thus, the cost to build the machine.
*The first independent replication is in process as of Sep. 2, 2011, by [[James Slade]] and Jason Smith in Texas.

Collaborative Production

Sigmund Petersen: /* See Also */

=Factor e Farm Case=

Collaborative Production is the means by which Factor e Farm intends to deploy prototypes rapidly - and to produce boot-strapping financial sustainability. It is a model whereby community members work together in production runs - after cross training its members to basic production skills.

By December 2012, we aim to demonstrate that we can produce $20k/month net bootstrap funding. We aim to produce a single CEB Machine in 1 day with 8 people working in our flexible fabrication workshop, yielding $5k per day. We intend to do 4 such production runs per month to allow ourselves to carry on research and development while enjoying the fruits of our optimized productivity.
