Over the past few days, Marcin and I have been working on the design of The Liberator 2 - the second prototype of our high-performance CEB press. The design is now up for review. The main changes are an enlarged, stationary hopper structure, guide rails that use cam followers, and an anti-bridging auger in the mouth of the hopper.

You can see our past presentation from the Oekonux Conference here.

Edward Miller, one of our True Fans, has organized a university lecture for us at Monmouth College in Illinois on April 22, 2009. If you’re in the surrounding area, please consider attending:

What follows is my personal experience and my evaluation of the design, if you want a quick read jump ahead to the evaluation at the end. According to Marcin and Jeremy I’m the only person to have slept in the Hexacube in below freezing conditions. (more…)

If you can proint 3D objects at home, that may be the end of Walmart. Yes - RepRap - the DIY open source 3D printer - is a major political statement.

To give you more flavor of the memorable Oekonux 4 conference of last weekend in Manchester, UK - here is a presentation given by Charles Collis that I reposted at the OSE wiki.

Six revolving tubes filled with eggs; the Hexahatch Revolution Incubator design is done and we will be building it tomorrow as part of a workshop. The design is open source on the wiki, complete with bill of materials and implementation plan. The cost looks to be about $70. Here’s a quick animation of the design and some pictures below:

Here is my talk from the 4th Oekonux Conference. You can download the slides and see a transcript here.

Start with an introduction by Franz Nahrada, leader of the Globally Integrated Village Environment:

That’s the title of Michel Bauwens’ post on the P2P Foundation blog regarding the recent conference, where I discussed our program for building the world’s first, replicable, open source, off-grid, Global Village. Read the rest of Michel’s inspiring post here. I share the feelings completely.
