Huh, I haven't hung out in /r9k/ on 4chan in a while- or in fact,
ever- so I'm glad to see that you somehow made your way here anyway.

Yep, you're in the right place. This is what we're mainly working on
here. The project idea has been mentioned in the past (decades ago)
hundreds of times over, but nobody has sat down and done it. I found
fenn (one of the other committers) by searching around for people
interested in David Gingery, and we've been working on this project
ever since we met. Smari and Sam Rose and a few others also started
emailing around last year about implementing this tech tree.
You're welcome to view our progress.
In particular, you can see a taxonomy of manufacturing processes here:
You can see some of the details filled out here:
You can see an example "package" in skdb, a package for a generic screw:
Ultimately this is hard to explain to individuals who are unfamiliar
with the concept of a "tech tree", or "tech graph", or unfamiliar with
"apt-get" or other free and open source software package managers.
These days I just tend to tell the diybio folks and the
openmanufacturing folks that it's "apt-get but for hardware". If you
haven't seen the xkcd sandwich reference,--
And of course, someone put some work into that very project already:
So, skdb is "apt-get but for hardware"- the idea is to be able to say
"skdb-get install milling-machine", or "skdb-make robot-maid", and
then get all of the requisite tools either by getting instructions
(computational representations of instructables), or by "opting out"
of the tree and just buying some OEM or proprietary components at a
certain point-- which I only mention because it's common that people
just want a kit, or don't want to have to forge every metal component
that they require to carry out their herculean feats.

So, one front-end idea that I have recently been bouncing around is
called "djangit". It's a python + django + git + wiki frontend system.
The idea is that many people don't want to hear about the guts of
skdb, but at the same time there's no reason to ignore proper revision
control systems; simultaneously, implementing in django means that the
python modules for skdb can be hooked in easily for rendering of the
package data (like the screw package), etc., while still allowing
human input over the web if someone so desires. At the moment djangit
isn't quite functional because I've been neglecting it for the past

In your spare time, you might want to read more about what we've

One of the problems that I continue to come across is that many of the
"open source hardware" sites on the web are just keeping photographs
of their information, which isn't useful because there's actual
engineering information involved that should be uploaded (like a CAD
file, etc.). But ultimately, yes, just like the alioth server on
debian, it would be useful to have a way to link to individual
projects and their presence on the web, yes.

Yep, we seem to be in agreement.

That's one part that the debian community (among others) has solved.
It is well known that engineering is not necessarily the most easy
task in the world because you can't just "engineer de novo"- it would
be pointless to engineer everything under the sun from scratch each
time you build it, right? So for this reason, there are already
"package maintainers" in the skdb community that accept projects from
others and help them "package them up" into the packaging format. This
way, everyone can just sit at their computer and say "sudo make me a
sandwich" and the computer handles all of the details like ordering
inventory, or printing out new lego-manual-style instructions for how
to assemble parts into a system that you wanted, etc. For those who
run shops or who have large machinery laying around, it would be ideal
to allow those machines to assemble the components for you, but
that'll lead this discussion off topic fairly quickly. ;-)

Yeah, that's called a version or revision control system.

We have some of this in the skdb/inventory/ folder but it's not
complete. Smari was working on a web interface to this, but he hasn't
showed up in the IRC channel (#hplusroadmap on freenode) in a few
weeks so I'm not sure what his status is.

I have absolutely no idea what Nathan is doing with yet another
project. We have a lot of momentum here that he's neglecting, and I've
invited him to learn more on numerous opportunities, but maybe I'm
just getting grumpy and old and grumpy.

I suggest starting off by joining the IRC channel (#hplusroadmap) and
saying hi, hanging around and seeing what's up. No doubt that you'll
slowly start to get the picture of what some of us are doing (or not

Hah. Well. We have a rule in the channel: no philosophy. We commonly
violate it without knowing it, until one of us reminds us of this
fact, and we realize we've all been barking up the wrong tree, and get
back to more practical work.
Anyway, nice to meet you.
