Fabulous Friends Smari, Kyrah, Olle, Erik, Edmund, Henri, and James X. Jones:
 
 
I would like to follow up on the concept of the OS Fab Lab. You have expressed interest in it, and I'd like to take a moment to see how you might want to participate. After you read this, please let me know your level of interest. In particular:
 
 
# Who else should we recruit for the organizational team?
# Who and how to contact others to find more collaborators?
# How much time could you devote to this?
# Can you serve on the organizational team?
# Can you set up a website for this?
# How can we enlist communicators, PR people?
# Besides the crowds, who can we tap for funding?
# Etc, etc.
 
The basic concept is that a set of advanced tools like the MIT Fab Lab – deployed at 1/10<sup>th</sup> the cost and ten times the functionality – could be a great boon to liberating Industry 2.0. This means the simple concept of: global design collaboration towards local fabrication. Transformative economic potential is huge, as personal fabrication takes over the work of large factories and slave labor. This is around the corner in the 21<sup>st</sup> century – if we want to make it happen.
 
 
The facts are that we are likely to get 10-fold cost reduction over the standard Fab Lab price of $100k. We've already proven 10-fold cost reduction with The Liberator (CEB press), and the same could be done with the MIT Fab Lab – which would include laser cutting at 100W, an induction furnace (20kW, 300 lb metal melt per hour), metal casting and rolling, plus heavy machining (mill, drill, press with 20 hp interchangeable hydraulic motor), metal press (also shears and punches holes). To top it off, let's add a robotic arm. Also, include technologically-recursive development of OS high power supplies for welder, induction furnace, and plasma cutter. Here's a summary of the tools included in the OSFL, their description, and their Bill of Materials (not including labor). This strategy involves a hydraulic power source for high torque and power applications, and 20kW of shop power.
 
 
These tools can get you from melting scrap steel, casting and rolling for parts, cutting, machining, lasing, routing, 3D printing, metal working, and circuit fabrication. This gets to all electromechanical devices known to humans, and can get us to just about all technology up to about 1980 or so. Combined with Arduino, it gives you automated control of CNC fabrication. The goal here is all the capacity of the MIT Fab Lab - plus much more: metal melting from scrap, heavy duty fabrication, and robotics. This is just a suggested approch. If OS, I don't see trouble getting to the prices mentioned.
 
 
I am hoping we could fund it by crowdsourcing from those who gain access to the designs. We can motivate donations by offering use of the developed equipment for making copies of the machines at ridiculously low costs. I would support this myself if I were to gain access to fabrication facilities and training.

One note – the laser seems like the most difficult item here. However, given access to laser tubes from laser engravers, this is not that difficult. Many amateurs even blow glass to make their own tubes. On the robotic arm – I haven't searched yet – but there must be tons of people knowledgeable and interested in it.

RepLab will need a robust way to represent and track designs, builds, edits, forks and all the other information management challenges of an open-source distributed hardware project.
 
Ben Lipkowitz and Bryan Bishop, among others, have put significant work into a system called SKDB. SKDB is a method for sharing hardware over the internet. "Hardware" means not just designs for circuit boards, but also biological constructs, scientific instruments, machine tools, nuts and bolts, raw materials, and how to make them. SKDB simplifies the process of searching for free designs, comparing part compatibility, and building lists of materials and components and where to get them. You could even say SKDB is "apt-get but for real stuff".
 
In SKDB, hardware is organized into packages. Packages are a standard and consistent way for programs to find data. Packages may contain CAD files, CAM parameters, computer-readable descriptions of product specifications, product-specific code, and bill of materials. For each part in a package there are a number of interface definitions, which describe how the part can connect with other parts, even parts from other packages. Each package also lists dependencies which have to be bought or built in order to successfully carry out a project. For example a drill press is required to make holes with a certain level of accuracy. SKDB downloads all of the dependencies automatically and compares them to your existing inventory, and generates instructions for your CNC machinery if you have any.

SKDB is new but extremely promising. Sites like Thingiverse are a great beginning, but 90% of the designs are for a RepStrap or a laser cutter, which both have the virtue of being reasonably 'plug and play'. With multiple tools displaying dependencies and requiring non-trivial human interaction, something more robust is clearly needed.
 
RepLab needs a representation format, and SKDB needs a meaningful test case to develop its functionality. At a minimum, all data for the projects should be described in YAML wherever possible.

We are not currently working on an opensource laser cutter. Some of our members are active with open source 3D printing, namely the RepRap and the Makerbot.
 
I do know that hacklab.to rebuilt a broken epilog and then taught it to sing (http://hacklab.to/archives/another-musical-variation/). They might have a couple of folks interested in opensourcing a laser cutter design.
 
Best,
Max
