On the topic of lost wax casting...
If someone knows a jeweler who has the equipment to 3D print in wax and
then cast in metal, let me know! This is the process Shapeways uses for
their precious metal 3D prints, but they charge an arm and a leg for them.
I would love to be able to produce 3D printed jewelry at the same rates as
these guys have figured out:
Also - you can totally do lost "wax" casting using 3D printed PLA instead
Lost PLA Casting from 3D Prints <http://3dtopo.com/lostPLA/>
Or you can even use low-melt alloys to cast directly into 3D printed ABS
Metal Casting with Your 3D Printer
PS: The "Field's metal" mentioned in the last link is a non-toxic alloy
that melts at 144°F, and is named after its inventor, local South Bay mad
scientist Simon Quellen Field.

I visited the old location a few times about a year ago and have been
out of the picture ever since for a plethora of reasons. Having just
moved to the East bay (Richmond), I'm interested in picking up
involvement with the Sudo community again but on a more committed
basis (becoming a member, helping with projects when I can, being in
the space in general, etc).
That said, I know you all are still in a transition phase and Omni
isn't officially open, yet. Reading notes from last week's Sudo
meeting, it seems like a lot of processes are still being smoothed out
and membership is being re-thought.
If this is a bad time to try and get my feet back in the door, I have
no problem waiting but I'm also available to help, too! I know new
folks have always been encouraged to stop by - just wondering if that
still holds in this transition period.
Hope to reconnect soon!

Last night someone came to the omni and rang the doorbell.
Someone inside Omni answered the door for this person, let them in, and
then asked them questions like "which group are you with" and "who do you
know here" and I guess the interaction didn't go ideally well.
At this point I became aware of the interaction and went over, introduced
myself to both people, and was reminded by the new person that we had met
before at old sudoroom. I said that the problem was solved and asked each
person if they needed anything else before going about their business, and
they didn't. The person who opened the door apologized to the person who
had been let in, and they went their seperate ways.
The person who was let in may have felt that they were being questioned
partially because of their race and that of the person who opened the
door. They may have been right. Only a scientific study could tell us
whether people are more likely to question someone of a different race in
situations of power and responsibility like letting someone "in".
Rather than continue such experiments, formally or informally, i suggest
we accelerate toward a flat system for situations where a person rings the
doorbell and the person who answers doesn't know them already. We can be
very specific about the instructions and attach them to a laminated card
tied near the door, so that the person being questioned knows that their
treatment is 100% standard regardless of their race or appearance.
The card should say something like this:
If you answer the door and you don't know the person, ask them their name
or nickname and which group's list they are on. You can check by typing
their name / nickname into the computer near the front door, and it will
tell you if they are on a list or not. (it may provide a picture or
description depending on that persons' preference)
If they are not on a groups' list, ask them if they are looking for
someone who is present at the Omni right now. If they say yes, offer to
help them find that person. (If you don't have time for this, don't
answer the door)
If they are not on a groups' list, and you can't find (with their help)
the person whom they are looking for, you need to decide whether to host
them as your guest or not.
If a group you represent values community involvement, treat this as an
opportunity to introduce a new person to your group by hosting them in the
space while you're there.
Offer them a tour of your groups' space, and tell them about the weekly
meetings and how to get more involved, and how to become a member with
door access (and getting their name on the list). Don't turn people away
If it seems appropriate, ask if they have a specific task they are trying
to accomplish, such as retreiving or dropping off an item. If they want
to take something, you will have to use your judgement as to whether it's
OK to do so without consulting someone specific about it. Perhaps they
can help you contact someone you trust over the telephone, or perhaps you
believe them because their story sounds good. Just do what you think is
best, and keep the person's feelings in mind when proposing an
alternative, such as trying again another time.
Keep in mind that when opening the door to someone without a key of their
own, you are in a position of power over them. With this power comes
great responsibility, and you are representing your group and the Omni
collective in general to whoever is at the door. Your actions have the
power to do great damage to years of community outreach, or to welcome
wonderful new people who will bring more great people along with them.
And remember that whatever responsibility you feel about protecting our
spaces from theft of some replaceable piece of equipment is not nearly as
important as your responsibility to treat each person with great respect
and care as you represent your community at the Omni.
Recently there was a controversy at Gittip which resulted in a project to
fork or rebuilding it with better governance structures and more focus on
the needs and safety of marginalized users.
They are figuring out how to run a web application in a cooperative
democratic way that focuses on the needs of the users, as opposed to a
TaskRabbit like model where a central corporation controls or extracts
value from their users and makes unilateral decisions.
They're working on bylaws and legal structures for this, and would
appreciate advice or connections to people with advice. Talk to them in
IRC at #atunit, particularly @adrienneleigh, or send me resources to pass
This is an exciting frontier for the cooperative movement. What if
TaskRabbit was owned by the rabbits? Websites have very concentrated power
structures compared to the number of users; what are effective ways to get
input from so many people who might not all be very invested in the
project? What other models can we draw from -- credit unions? What
lessons can be learned from Wikipedia? Etc.
This especially matters for this particular use case, recurring donations,
because some people will be making their living off of proceeds from the
site and it's important that their voice is heard.
Sudoroom may be one of the largest users of this site when it launches,
like we are now with Gittip.

I could ban you right now, but if I do, I want it to be VERY clear
that it's not targeting a person or even a person's politics, but an
ongoing pattern of racist behavior. I would much rather you REALIZE ON
YOUR OWN that this is not the community for you.

This is a white supremist perspective that, among other things, erases
the many people of color who write about gentrification.

so, sudoroom has a robot arm now. It took a lot of people and creativity
to get it in!
I have started sorting out the control box and I am removing the "spare"
box that housed motor controllers for the assembly line, which are
seperate from the robot itself. The robot's last job was building parts
The robot and its control box (and the 48 foot long cables that connect
them!) are dirty! If you want a good start with this thing, consider
grabbing a towel and some soapy water and cleaning it off. Nobody likes a
dirty dog that marks you when you play with it.
At present, the robot arm itself is in the CENTER of sudoroom. I know
this is not necessarily a good place for it once it's working, but since
the pile of doors is still where it is (because we still don't have a
shop-vac to clean out the place where the doors are going?) and I didn't
want to put it by the wall (because then the cords wouldn't reach) and I
have to return the pallet jack today (the only way to move it) it will
have to stay there until we decide on wednesday where to put it. And then
we will need to borrow a pallet jack from somewhere...
I propose that we keep it in the middle of the room until we get it to
work at all, because until then (and i don't know how long it will be) it
is totally immobile and thus not dangerous. But we will have to talk
about it at the meeting, of course.
But my personal opinion is that we should keep it in the middle where it
is, after tuning its control systems to make it impossible for it to move
rapidly enough to hurt anyone. But I realize some people will object to
that suggestion and I respect that.
If you are interested in doing things with the robot arm, such as learning
how it works and how to operate it, let's talk about it. Also, we can
start thinking about what to use it for!
I think we should find a material (such as wax) that we can allow it to
extrude like a 3d printer (but with a large bead) so that we can practice
making big things. Also the people who sold us the robot can turn wax

Agreed. Thank you Praveen for saying something.
I think it's disgusting to hear a white person use other peoples'
experience of racism as a rhetorical pawn in her petty off-topic
arguments about housing policy. I do not want that to be the tone we
set for Sudoroom.
Tech Boom Spurs Changes in West Oakland

Once, you may have gone to West Oakland to hear James Brown or Aretha Franklin play the clubs on Seventh Street. The street was the center of a neighborhood rich in African-American history. NBA legend Bill Russell lived in West Oakland, and the Black Panthers had an office on Peralta Street.
But the clubs closed decades ago and Bill Russell is long gone. In their wake, a new wave of residents are sweeping into the neighborhood — many of them white, and many of them coming from San Francisco because of the tech boom.
According to the 2010 census, Oakland has more white inhabitants than black residents for the first time since the 1970s. Neighborhoods have been changing for decades, but the expanding tech industry is speeding up the process.
Meanwhile, sky-high rents are pushing people out of San Francisco, with many ending up in West Oakland, the first BART stop on the east side of the bay.
Over the last few decades, West Oakland has seen an increase of abandoned factories and shuttered businesses. Danita Robinson, a member of the Center Street Baptist Church on Tenth Street, says for a long time nobody would invest in West Oakland. But she says there is now more development in the neighborhood.

For instance, developers recently built a high-end condo complex in West Oakland called Zephyr Gate. It’s a couple of blocks long and within walking distance from the West Oakland BART stop.
“That was so abandoned for such a long time,” Robinson says. “Now it is all nice over there and Mr. Google and Mr. Doctor are living there.”
Referring to to an old nickname for one section of the neighborhood, she asks, “What could we have put back there outside of these condos that would have been beneficial to the West Oakland area, especially what we call the lower bottoms down here?”
Kenna Stormwell-Gougis lives in a Victorian across from the Center Street Baptist Church. She bought the house a decade ago.
“I was the only white person on this block 10 years ago,” she says, “and now, I would say the block is 40 percent white.” She says lots of new people are riding by on bikes and popping in and out of old Victorian houses.
Danita Robinson doesn’t think of the newcomers as West Oaklanders.
“I call them San Franciscans,” she says. “Why else would you be moving to this area and not another area of Oakland? Because it’s three blocks from the BART station.”
Dawn Phillips is the program co-director at Causa Justa::Just Cause. His organization published a report that shows some market-rate rents in West Oakland to be higher than in Rockridge and the Oakland Hills — two of the most affluent areas in the city.
“When we looked at that data it blew us away,” Phillips says. “We did not know that.”
Rent is rising throughout Oakland. The real estate company Trulia says rents increased 10.8 percent in May from the year before. That is the third highest rent hike in the country behind San Diego and San Francisco. The median price for a two-bedroom is now $2,450 a month.
“This is a regional pressure that is being created,” Phillips says. “It is rippling out from San Francisco.” Soon he says, it will hit neighborhoods farther out in the Bay Area.
In gathering data for their report, Causa Justa::Just Cause found an increase in the eviction and displacement of Africans-Americans from Oakland. Phillips says the current demographic change is just the final stage after decades of disinvestment in the area: “We understand gentrification to be pretty long-term, long-evolving historic process that is actually very systematic in nature.”

Ron Lindsey can tell you first-hand how the long-term process played out in West Oakland, where he grew up. His father and uncle worked at the Navy shipyard. He saw that get shut down and the factory jobs shipped overseas. Then the businesses on Seventh Street started closing. He can still point out where they all were — a clothing store, a shoe shine parlor, barber shops, candy shops and night clubs. “All of these were black businesses,” Lindsey says.
After companies outsourced the neighborhood’s factory jobs, the tax base eroded and social services were cut. Unemployment and violence spiked. Lindsey watched as highways and train lines carved up the neighborhood. The elevated BART rails got built right over Seventh Street. Now where there was once music, there is the screech of trains, drowning out everything below. People left. Eventually, so did Lindsey.
Phillips says gentrification is this whole progression, from job loss to neighborhood decay to redevelopment.
Danita Robinson says even though things are changing, there is no way for her to move up.
“I don’t want to be low-rent,” Robinson says. “I don’t want to be low-income. I would like to move up. I can’t afford that condo. It looks nice. I want to be in that condo. But you killed all my jobs, so how am I gonna get in that condo?”
Robinson cleans houses for a living, and her husband works two jobs. The couple is expecting a baby, so she hopes they can find better employment soon.
