CEB Press Automation

Pressing Rate Maxed Out at 16 Bricks Per Minute

Speed trials on our automatic, open source CEB press, The Liberator, are complete. We achieved a maximum brick pressing rate of 16 bricks per minute, or less than 3 seconds per brick. We have run sufficient tests and worked out the bugs in the control...

Initial CEB Field Testing Report – The Liberator Beta v2.0

It was raining for a week straight, and this Thursday, we finally documented initial field operations with our open source CEB press – The Liberator Beta v2.0. We used the soil pulverizer to pulverize the soil, and we used the tooth-bar bucket to...

The Liberator Beta 2.0: Machine Overview

Things are looking up on the fully automatic, open source, CEB press РThe Liberator  Beta v2.0. We finally have the machine ready to run in field tests. The basic operational description is here, from the front: and from the back: Some noteworthy...

13 Bricks Per Minute… and Counting

Today’s goal was to determine maximum pressing rates attainable with The Liberator, the open source CEB press. We obtained data to verify some of the predicted rates shown in italics in this table. To boost morale, we started by pressing thin, 2...

CEB Automation with Sensors

For the last two months, we’ve been developing and implementing Prototype 2 automatic controls for the open source Compressed Eearth Brick (CEB) press. We had initial results from Prototype 1 controls, without sensors, back in November. This time,...

CEB Press: Building on RepRap and Arduino

The CEB automation for the Liberator Beta 2.0 open source CEB press builds on other open source projects. We are using: (1), power drivers from the RepRap project for driving the solenoid valves; (2), Arduino as the controller-brain for the brick-pressing...
