=Overview=

The Compressed Earth Brick Press operation is automated using a microcontroller.

Code is uploaded to the microcontroller and the microcontroller saves the code; when the microcontroller is turned on, it will run the saved code to control the other CEB Press electronics; the CEB Press operation code is written to loop so that the operator does not need to reset the microcontroller for each brick.

The code commands the microcontroller to send digital signals to the solenoid driver, which powers the hydraulic solenoid valves. The hydraulic solenoid valves open hydraulic flow to the hydraulic cylinders for motion.

*'''Upload the Code to the Arduino Microcontroller'''. The steps are explained in the following link.

http://opensourceecology.org/wiki/CEB_Press/Manufacturing_Instructions/Code_Upload

*'''Power Off the CEB Press Electronics'''. Turning off the power to the microcontroller and solenoid driver ensures that the hydraulic solenoid valves are not activated when turning on hydraulic flow. You can do this by disconnecting the CEB electronics from both the battery and the computer.

*'''Perform CEB Press Area Safety Check'''. Ensure that no unintended objects are in or around the CEB Press area.

*'''Turn On Hydraulic Flow'''. Because the hydraulic solenoid valves are not activated, they will be in their neutral, '''open''' position, which allows the hydraulic fluid to '''directly''' return to the pump. '''If you experience operation problems, disconnect the CEB Press electronics from the battery or shut off hydraulic flow.

*'''Power On the CEB Press Electronics'''. Connect the battery to the CEB Press Electronics. The microcontroller's LEDs should light up to show that the code is running. The solenoid driver's LEDs should light up to show which direction the hydraulic solenoid valves are being powered, if any.

*'''Check Proper CEB Press Operation'''. Look at the motion of the CEB Press and ensure that the soil loading, soil compression, and brick ejection movements are correct. Note that the CEB Press has an '''initialization sequence''' that is not part of the operation loop.

*'''Load Soil'''. Safely dump soil into the CEB Press hopper. You may want to view the CEB Press operation from the top of the hopper to check whether the soil is loading into the soil drawer; observe safely.

*'''Check Compression Pressure'''. Observe the reading on the hydraulic pressure gauge during the compression. The value should be at least 2000 psi.

*'''Check Compressed Earth Brick'''. Check the physical characteristics of the brick. Ensure that the brick is not warped (ex. curved).

==Sensors==

'''Sensors''': Take one of the two sensor assemblies. There should be a mark on the sensor assembly noting the correct side of the sensor that you must put closest to the magnets. The Hall Effect Sensor inside the sensor tube is about 1/2" from the end of the sensor tube. When the sensor is moved over a magnet, one of the two sensor LEDs on the controller board should light up. This defines the magnet orientation for turning on the sensor. If the LED does not light up, flip the magnet onto its other face. This applies to each of the sensors. The main cylinder is connected to pin A0, and secondary cylinder is connected to pin A1. See [[CEB_Press/Manufacturing_Instructions/ElectrohydraulicIntegration]] for wiring diagram:

=Overview=
[[File:Liberator_bricks.JPG|right|400px|thumb|Bricks pressed on [[The Liberator]]]]
The Liberator is OSE's automatic, high throughput Compressed Earth 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]].

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.

*Using the tin snips, cut 6 pieces of 20cm black wire, 2 pieces of 20cm red wire, 5 pieces of 1.5m black wire, and 1 piece of 1.5m red wire.

*Using the wire strippers at 22 gauge, strip half a centimetre at one end of the 6 pieces of 20cm black wire and 1 piece of 20cm red wire.

*Using the wire strippers at 18 gauge, strip a centimetre at the other ends of the 6 pieces of 20cm black wire and the 1 piece of 20cm red wire, as well as both ends of the other 1 piece of 20cm red wire, the 5 pieces of 1.5m black wire, and the 1 piece of 1.5m red wire.

*Using the crimper, crimp the 10 to 12 gauge ring insulated connector at one of the 1 centimetre stripped ends of the 6 pieces of 20cm black wire, the 2 pieces of 20cm red wire, the 5 pieces of 1.5m black wire, and the 1 piece of 1.5m red wire.
Also crimp the 10 to 12 gauge small hole ring insulated connector at the remaining 1cm end of the 20cm red wire and crimp the 14 to 16 gauge ring connector to the remaining 1cm ends of the 5 pieces of 1.5m black wire and 1 piece of 1.5m red wire.

*Using the screwdriver with the number 2 philips bit, connect the small ring end of the 20cm red wire to the remaining power switch terminal.

*Insert the large ring end of the 6 1.5m wires through the bottom-middle hole of the lug box.

*Using the screwdriver with the number 2 philips bit, connect the large ring end of the 1.5m red wire, the remaining ring end of the switch-connected 20cm red wire, and the ring end of the other 20cm red wire to the bottom-left screw of the terminal platform.

*Connect the large ring end of the 5 1.5m black wires and the ring end of 5 20cm black wires to the top 5 screws of the terminal platform. Then connect the ring end of the remaining 20cm black wire to the bottom-right screw of the terminal platform.

*Using the flathead screwdriver, connect the half centimetre ends of the 6 pieces of 20cm black wire to the lower terminal of the 5 mosfet terminal blocks, and the left terminal of the power terminal block. Note that the mosfet connections from left to right on the terminal platform should go from bottom to top on the solenoid driver. Also connect the half centimetre end of the 1 piece of 20cm red wire to the right terminal of the power terminal block.

*Insert the 2 sensor units by their wire end into the right-bottom hole of the lug box.

*Using the flathead screwdriver, connect the bluewhite wires, orange wires, and blue wires into the top, middle, and bottom terminal blocks, respectively, on the right side of the solenoid driver.

*Using the screwdriver with the number 2 philips bit, screw-tighten the wire clamp at the right-bottom hole of the lug box.

==Overview==

{{CEB}} Design

[[CEB 4 design planning]]

==Components==
The Liberator consists of -<br>
*A '''[[CEB Press/Manufacturing Instructions/Hopper|Hopper]]''' at the top which you fill with loose dirt. This is made from welded steel. We made the hopper six feet wide, so it can hold a lot of dirt.
*'''Grate and grate shaker''' - the grate is at the bottom of the hopper. The grate shaker shakes it so that soil falls through into the compression chamber, while large stones and things like that are caught in the grate.
*A '''frame''' that bolts together for easy assembly and disassembly.
*A '''compression chamber''' where the bricks are actually pressed. This is a metal box with a nylon liner bolted on the inside. The liner gives the bricks a smoother finish. It will have to be replaced every hundred thousand bricks or so.
*'''Hydraulic cylinders''' - These are the muscles of the machine; they apply the pressure to the dirt. They are readily removable with pins. There are two hydraulic cylinders:
*The '''soil drawer''' - this moves from left to right and performs the dual function of loading soil into the compression chamber and ejecting blocks from the machine
*The '''main cylinder''', which moves up and down and compresses the blocks
*'''Tractor mount''', where an external hydraulic power source can be attached to the hydraulic cylinders.
*'''Pressure gauge''', which monitors the amount of pressure used by the hydraulic system to ensure a certain density of brick.
*'''[[CEB Press/Manufacturing Instructions/Controller Box|Controller Box]]''' controls the timing and sequence of operations.
