Jakubowski built the first LifeTrac, as he calls his DIY tractor, in three months for $6,000—about $30,000 less than a comparable mass-produced model. Seeing room for improvement, he built a second prototype in just six days. He posted his progress on the tractor and other machines to an online wiki, which attracted followers, who suggested their own design tweaks. Some even visited in person to help with builds—and Open Source Ecology took off.
Led by Jakubowski, the group now designs open-source agro-industrial machines on his “Factor e Farm.” The fourth iteration of LifeTrac isn’t like the industrial equipment on most farms; it works with a variety of custom attachments, including two removable, office-copier-size hydraulic engines called Power Cubes. The cubes also power other pieces of the Global Village Construction Set: 50 machines—ranging from 3-D printers and CNC mills to bakery ovens and brick presses—that the group deems essential to modern society (see “Multipurpose Power,” next page).
Once all of the blueprints hit the Web, the group will shift from prototyping to multiplying. The idea: With a few raw materials and a starter construction set, users could copy all the machines.
Some examples of the machines that can use a common power source:
