We are making good progress on LifeTrac – Prototype II of the open source tractor. We have managed to fund its completion via crowd funding. We’ve got just about all the parts in, including hydraulic components. We will use Power Cube Protype I as the initial power source. After completing the frame, the next tasks are wheel mounting, as well as installation of the hydraulics and of the Power Cube. Here is the progress on various wheel mounting and loader arm mounting components. This is another beautiful production by Sean:
Here are some additional details from Sean’s video documentation work regarding the frame of the open source tractor – LifeTrac – Prototype II. William discusses some of the details on the frame, which was introduced in a previous post. From Sean’s videos so far, I like this one the most so far for its aesthetic qualities. You can read more about LifeTrac Prototype I here.
William has been here for 2 months already, and here’s his second Dedicated Project Visit report. Don’t miss this video if you want to see 3D models and a time-lapse video of LifeTrac II – the second prototype of the open source tractor – coming together. You can read about our first prototype here.
We are working on the second prototype of the open source tractor, as discussed in the last post. We have come up with a sketch for the new LifeTrac II frame, which was drawn in Blender. The disks mark the location of the wheels, and the middle verticals will serve as the attachment for the 2 loaders – front and rear. The idea is to come up with the simplest, replicable, design-for-disassembly, lifetime design consistent with our specifications.
We intend to develop this sketch further until we have a fully working 3D model to reference when we come to physically building LifeTrac II in the workshop. The usefulness of Blender is to determine exact bolt locations and sizes of structural members. This is especially useful when designing the loaders and quick attach plates – where we can model the heights and angles required prior to building. You can see our initial designs from over a year ago for reference – on the evolution of the project. (more…)
Marcin takes us into Factor-e-Farm One-Room-Schoolhouse again and this time to explain the concept behind designing and then building the open-source-tractor, LifeTrac II. This 5 minute video lays down the foundation from where we will begin.
Coming next on the “LifeTrac II” project we will have some basic frame designs drawn up in Blender open source 3D modeling software – to see how the proposed design will function. See past work on LifeTrac.
A universal mechanical power source is one of the key components of the Global Village Construcgtion Set – the set of building blocks for creating resilient communities. The basic concept is that instead of using a dedicated engine on a particular powered device – which means hundreds of engines required for a complete resilient community, you need one (or a few) power unit. If this single power unit can be coupled readily to the powered device of interest, then we have the possibility of this single power unit being interchangeable between an unlimited number of devices. Our implementation of this is the hydrauilic PowerCube – whose power can be tapped simply by attaching 2 hydraulic hoses to a device of interest. A 3/4″ hydraulic hose such as this
can transfer up to 100 horsepower in the form of usable hydraulic fluid flow.
You may have seen our prior report on PowerCube as the power source for MicroTrac. The question is – how flexible can the PowerCube be? We ask this question from the standpoint of the PowerCube’s suitability as an essential component for building resilient communities – or, how radically small can your infrastructure tool-set be, if your goal is creating a modern, high quality of life?
To shed some light on this question, we mounted the PowerCube on LifeTrac, our open source tractor – to demonstrate the radical interchangeability of parts. This radical modularity is the key to what we promote as the life-size Lego set for real technology. We mounted the PowerCube on the rear receiver of LifeTrac, and ran LifeTrac with it. Here are the results:
One conclusion is clear. The PowerCube concept of power unit interchangeability is sound. (more…)
William and I have been hashing out the details of construction for the coming year. Our plan is at this wiki page and further details on techniques to be used are here. We are currently planning on a CEB-straw bale hybrid – a double CEB brick wall with straw bale inside. We expect the R-value to be at least 40 – making it a super-insulated house. Add the solar space in front, and we would not need a pile of firewood for winter, as shown in the following video. The video shows the location for this construction – close to the water well so we can have year-round water without doing too much trenching for water pipe.
Noteworthy features are CEB floor, masonry stove, living roof, rainwater catchment, greenhouse in front, open source air-powered water pump, our own lumber, CEB water cistern, and keyhole growing space right in front. This means that in May, we will build LifeTrac II, PowerCube II, and the dimensional sawmill. In June and July, we’ll test the toolchain – cut lumber, test stabilized and lime bricks, do the well pump and prepare water lines, do site preparation, build trusses from our lumber, prepare brick rollers, test slurry mixes, and other details. If we’re on top of it, we’ll begin the wall-raising on August 1st, and hold a CEB hybrid construction workshop.
In the meantime, we invite open architecture collaboration – coming up with technical drawings and models, as well as working out the details on all the other house subsystems.
William Cleaver will be joining us at Factor e Farm on May 1 for a Dedicated Project Visit. He’s coming from across the big pond – from the United Kingdom – and we are planning for a 3 month stay.
William is not a novice to creative dexterity – he’s involved in repair and demolition of industrial chimney stacks and natural draught cooling towers – at heights. See for yourself:
He has experience with various tools, welding brickwork, ropework, woodwork, and general shop. He’s traveled the world, studied Romance languages, taught English in Chile, and is certified to teach high ropes courses. He is now showing great interest in the deeper message of post-scarcity, resilient community creation.
We discussed the following tentative plan, with both of us working in the shop and as needed:
May – Work on finishing or building Sawmill/LifeTrac II/MicroTrac II/ anciliary implements for construction – all in preparation for building.
June – begin building autonomous, zero energy housing with solar space. Experiment with CEB floors, CEB masonry stove and chimney, stabilized bricks, stabilized reject lime bricks, stabilized brick walkway and driveway, stabilized retaining walls, and others. We plan on winter food garden and sprouting in the solar space. If progress on the steam engine goes well, we’ll aim to install combined heat and power on the masonry stove.
July – continue building until comfortable accommodations for the winter are ready for several people.
We’re looking at building zero energy homes that look tentatively like this:
Other than this, William is learning Kdenlive on Linux for movie editing, as well as and QCad for CAD work. These are staple tools now at Factor e Farm. William will begin preparing some of the technical drawings for the sawmill, so we can collaborate on making that happen over distance until his arrival.
We do want to consider bringing in additional help from the CEB general contractor, Floyd (see last blog post). We will consider hosting a CEB workshop if progress is good. If the CEB fabrication is going well – there could be resources generated to really get things moving forward, and continue to build more structures. I think now is the beginning of really settling into the land – and getting the place to look half-way presentable. We’re open to all kinds of ideas, such as the proposed CEB vault construction and others – but we’d need other people to get involved to push those projects forward. Otherwise, we’re sticking to basics and all types of experiments in the process.
From post-scarcity communities, open business models, open source tractors, land stewardship, to starting some serious building this year – here’s the latest:

We are farmer scientists - working to develop a world class research center for decentralization technologies using open source permaculture and technology to work together for providing basic needs and self replicating the entire operation at the cost of scrap metal. We seek societal transformation through interconnected self-sufficient villages and homes. This is a stepping stone to transcending survival and evolving to freedom. Factor e Farm is the land-based facility where we put this theory, Open Source Ecology, into practice. More
