Rapid Prototyping for Industrial Swadeshi
There is a significant set of open source technologies available for rapid prototyping in small workshops. By combining 3D printing with low-cost metal casting, and following with machining using a computer controlled Multimachine, the capacity arises...
Ecotechnology Buying Club
It’s time to take our open source product development to the next level. The next on the Compressed Earth Block (CEB) press prototype development is a computer controlled XYZ table for automating acetylene torch cutting of the metal. You may see...
CEB Press Prototype 1 Completed
It is interesting to see the progress on the Compressed Earth Block (CEB) press from prior art: to our own conceptual and design drawings: to raw metal as shown at http://blog.opensourceecology.org/?p=36 and to reality: Now we take a mound...
CEB Day 20 – Winter Migration
On the Compressed Earth Block press, I am looking to press the first brick today. The mounted pressing cylinder looks like this: It got into the 20s on the Fahrenheit scale, so I moved development operations into the greenhouse. We have a good stove in...
Solar Turbine Update
Yesterday I talked to Dan Granett of Granett Engineering. He made a boundary layer turbine successfully, and has performance data (please let me know if you know others). This turbine is an external combustion engine, and is a cheaper, simpler, and more...
CEB Day 11 and Update
Quick update. On CEB, I am hoping to spit out the first brick by this week. The flexible fabrication front is hot. Deep in the fiery Iceland underground, Smari and his Fab Lab team are working on an open source, computer controlled XYZ table for acetylene...
