tl;dr can we put this giant robot arm at sudoroom?
this is a six-axis robot with controller. It is actually a MIG welding robot, but we can use it for whatever we want, like a giant 3d printer. It is intended to be secured in position to the floor, or a platform of some kind, and weld metal pieces according to a program you teach it.
if Sudoroom can offer the space for this item, i think it will be a valuable tool and learning platform for robotics, electronics and mechanics, and an opportunity to develop new uses for tools like this.
After restoring the robot to functional status (by volunteers including me) we can play with it in various ways, like use it to play chess (including flipping the table over if it's about to lose)
Later i think we should attach a plastic melter/auger so that the arm can dispense melted ground-up #2 milk jugs or #1 PET soda bottles, and become a large-volume 3d printer. we could put a camera and/or primesense on the end of its hand and make it a 3d scanner or computer vision platform…
If sufficient ventilation is provided to its area, it can actually be used as a MIG welding robot if people want.

Q: What's the catch?
A: Sudoroom must devote about 16 square feet for the control boxes and about 16 square feet for the robot itself.
Q: How much will it cost?
A: The price is $200 total, but we will have to find a pickup truck to transport it to sudoroom from berkeley. The sellers will load it onto the truck with their forklift, and we may need a forklift to get it down.
Q: But we don't have three-phase power! Isn't 8 KW a lot of power?
A: We can modify it to run on regular 2-phase power, and ideally we will significantly reduce the size of the power source at some point anyway. And 8 KW is the maximum rating, moving continuously at full speed AND welding the whole time. Powering it will not be a problem.
Q: Who is paying for this?
A: I (jake) have $20 on it and at least a couple of other people also are interested. Will you also contribute money or time to this project?
Q: What's the worst thing that could happen?
A: We end up scrapping it because nobody cares about a giant robot :(

I've been working on the door access system all night. Everything was
working fine, but now close works, but open does not, the motor just stops
half way. I'm sorry for the inconvenience, but I have to stop working on
this and come back tomorrow.
Until then I have disabled the mag swipe to prevent any damage to the
This is perhaps the greatest news I've read on Sudo Discuss EVER. It has
always been my dream that Sudo Room provide public computer terminals for
folks without access to the hardware, for classes such as basic computer
literacy, and for events that require computers such as Oakland Wiki
Ed, how can I help?
Not enough people came to the meeting tonight to hold a true meeting and
have quorum for approving our three new member requests. I heard that last
week's meeting was also sparsely attended. Given that we're in a transition
stage, should we consider postponing meetings until, say, August? (And just
to get all meta/catch-22 on you, can we even make this decision without
holding a meeting? The twilight zone...). Anyway, here are some pseudo
notes taken by Julio:
People pseudo-present at Sudo Room meeting:
+Vicky will scrub the wordpress to make sure it's clear that we are now at
the new place (someone may have already done this)
+Vicky will update the Google Place for Sudo Room
+Julio will upload photos for how to access the new Sudo.
+Julio will scrub Sudo Room Wiki and Oakland Wiki to make sure it's clear
that Sudo Room is now at a new location.
+Three prospective members (Timothy, Elizabeth, and Whitney) were waiting
for a meeting that didn't happen due to lack of quorum (10 Sudo members)
pursuant to the current process for becoming a member:
+They will try again next week though Timothy suggested that we may
consider having an acceptable process that does not require a quorum at a
physical meeting. He had other ideas about making decisions collectively
online, when necessary, using reddit or reddit-like tools (including one he
recently coded, but is in beta). Timothy will address the Sudo Room
community via email with suggestions.
+In the absence of an alternative process, it was suggested the prospective
members ping the lists/IRC/etc to see if a meeting is actually happening in
case that's their sole reason for coming to Sudo Room on any specific
DONATIONS + 501C*
+Whitney came representing a network hardware group after following a
suggestion from Daniel that Sudo should be able to solicit and accept
donations like old networking equipment from school districts when they
acquire new equipment. The group has to be able to accept donations that
are tax-deductible, and this is only possible if Sudo has federal
non-profit status [501(c)(*)], and the Sudo wiki states that process as
pending. It is not clear that a decision has been made. Whitney will
message sudo-discuss and sudo-board about his request for information.
Soliciting donations for SudoRoom will be greatly assisted with a federal
501c(3) status. Without this classification federal tax incentives are not
available to those wishing to donate or to those paying members looking to
write off dues, and soliciting of donations w/o this classification is
legally questionable. Additionally there is the potential for tax exemption
of purchases however this will require (in addition to filing and gaining
approval) an internally developed mechanism for members to benefit when
making SudoRoom related purchases.
Costs of operating a 501c(3) depend on the amount of revenue. I assume
SudoRoom is below the $2million threshold of revenues so audits will not be
required. There are miscellaneous fees associated with filing yearly
paperwork (all totaled less than $100/yr).

of the current Attorney General Status (note that SudoMesh is identical) in
addition to the published guide for charities, specifically the section
beginning on page 46 "A Summary of Important...".

We’re excited to announce that the Prelinger Library has invited us to join
them at the end of July for an editathon on gentrification in San
Francisco! The *Prelinger Library* <http://www.prelingerlibrary.org/home/>
is a private collection of rare books, maps, zines and other ephemera held
by Rick and Megan Prelinger, both “appropriation-friendly” librarians.
*Rick* <https://en.wikipedia.org/wiki/Rick_Prelinger> is well known in the
film archive world for his fascinating collections of American home movies
and for his work with the Internet Archive. *Megan*
<https://en.wikipedia.org/wiki/Megan_Prelinger> is a cultural historian,
whose research and writing has ranged from artificial intelligence and
information design to city planning and social theory. Megan will be
curating a personalized collection of books and ephemera for us to use in
Since the library study area is rather small, they have asked that we limit
participant numbers. We’ve been hearing a lot of strong interest in this
editathon, so in order to accommodate as many people as we can, we will be
splitting research times into three groups:
- Wednesday, July 23rd, 5-8:30 pm (6 spaces)
- Saturday, July 26th, noon-3pm (12 spaces)
- Saturday, July 26th, 3-6 pm (12 spaces)
Please RSVP either by emailing me privately or by adding your name to the
wiki event page: <*http://localwiki.net/sf/Gentrification_editathon
<http://localwiki.net/sf/Gentrification_editathon>*>. *Sign up for as many
times as you'd like to attend, but if the slots get filled you may be asked
to go to a less-popular time. Sorry! *:P
