Hey everyone,
I just got back from HOPE last week and i have some renewed energy to
bring back a hackmeet type event. There will be a name change, now known
as RiotCon. The emphasis will be on art, society, hacking, and rupture.
I'd love to host it at sudoroom, but i don't know if that viable yet.
Looking at doing it early next year most likely.
If you're interested in helping plan it, let me know.
Hurray!
Gregg Horton
Hey guys,
We are not open that means you cannot sell your used bike to someone off CL
here in a way that can hold us liable.
A family just drove down from Concord trying to buy someone's bike of
craigslist in which the seller did not leave their name, actual email, or
phone number, just the address. The seller was nowhere to be found. Is this
bike stolen? That would get us in deep doo-doo.
We are *not open* and there is absolutely no way individuals can legally
use the omni to sell personal things especially like that and list our
address on craig's list as if we are selling it. The omni does not have a
sellers permit, are not insured for that, nor anything of the sort and we
can be held liable if it is stolen.
Whomever set this up, please contact me. I am not upset - but it is truly
imperative we all understand this. (Yea TIL sells things, but they are a
business with a clear reason to do so and don't advertise stuff anonymously
on craigs list.)
Anyhow if anyone reading this knows who this is or anyone selling anything
like that out of here please inform the list asap.
If anyone has any questions please call or come talk to me *and take down
that ad please.*
I attach the email from the buyer I asked them to forward, a screenshot of
the CL ad, and the url:

Best,
David

Hi Hol,
that's a really neat welder! If you want to tune it up and make it work
better, you might want to replace the tube that the wire gets pushed
through. When it develops friction, the drive wheel can't push the wire
through reliably.
Fortunately the tube can be replaced with bicycle brake cable! Just get
some of the good stuff (teflon lined) from a bike shop, and razor off the
rubber coating so it fits in place of the original hose. The welder will
work better than new!
As for the flux-core wire, it is very dangerous to use that indoors,
because the flux is for preventing oxidation - and our lungs need to
oxidize! So it should never be used indoors (and using it outdoors will
require a shield so passersby don't see the arc)
At some point we should talk about making a ventilated corner of sudoroom,
where welding and other fume-producing tasks can take place. Hell, maybe
the Robot will be welding by then.

i brought in a small wirefeed welder. it uses fluxcore wire so doesn't
require a shield gas, just turn it on, clamp the ground to your work,
point and click. the wheel that drives the wire from the box through the
cable to the gun doesn't have very good traction, so check there if the
wire doesn't feed. the welder uses 17 amps so only use directly plugged
into an outlet (!!!)
bring steel! the antique saw actually works really well for cutting
stock down to size
Thanks for documenting whats happening w the Robot, Jake. Its like a little movie script in my mind. :)

omg i think i figured out what's wrong
it's not throwing errors for servos 1 and 2 of the robot, it's referring
to the two motors that are not connected, they were part of the assembly
line. We actually have the controllers for both, they were in that huge
metal box I put on the curb (after taking them out) but we only have one
of the motors and anyway...
on page 28 of http://servo-repair.com/documents/yaskawa/CACR-SR.pdf
(labeled page 23 in the document) it shows the pins of the connector for
the errors we're getting.
I think if i short the right pins on the connectors, the errors will go
away and it will think the two missing servo controllers are happy, even
though we don't actually want to hook them up to anything.
unfortunately, reconfiguring the ERC controller to know that it doesn't
have two extra motors would require changing the EPROM, and even if we had
a ROM burner handy I wouldn't know what to change.
Does anyone want to play with the robot arm?

whoa... the encoders are serial? I guess there's a lot of stuff in there.
the pinout is on page 26 but look on page 31:
http://servo-repair.com/documents/yaskawa/CACR-SR.pdf
apparently the encoders power on, and report their absolute position with
a serial data packet, and then they switch over to quadrature to report
movement pulses. Maybe this is why the pinout includes "battery" and
there is supposed to be a battery to allow the encoders to "remember"
where they were before?
i guess if we fix the battery, and fix whatever loose wires are causing
servos 1 and 2 to not pass tests, then it will probably work.

There are more Yaskawa documents here:
http://servo-repair.com/documents.php
The robot was made by Yaskawa which is now know as Motoman (subsidiary
of Yaskawa). However, it seems like Yaskawa does not put any
documentation about this on their website. I don't know who made the
encoder but I think it might be Stegmann.

Hi Chalkeristas/istos--
HELP! I am an artist doing complicated social projects and I need a web
presence that makes sense. For instance, I am starting an alternative
credit rating bureau, starting with one experimental loan to one person. It
feels important to have a good way to communicate about this. I am not sure
where to start, what to ask or search for, or how to value it.
I have a small amount of money from a grant to work with, and I'm happy to
do a money thing or a trade thing, and I'd even just be happy to get some
advice.
Thanks a million!

I don't normally post a lot of stuff on international tech politics to
hackerspace lists, but I think it's worth generating a conversation around
this. My friends from Russia have been describing Putin's insane
environment of fearmongering and national media control and censorship.
This article talks effectively a national walled garden.

How do you fight this?
A totally badass and very knowledgeable and kind friend of mine is
co-hosting this event. I'll be there...come with me! :] Here's some info:
[[August 17th, 2pm @ LOL 1234 23rd Avenue]]
"come kickit with some great folks at a hands-on radical digital mapping
workshop!
we'll be mapping data sets about (1) charter schools replacing public
schools in oakland, (2) payouts & settlements from OPD police brutality,
and (3) foreclosures in the bay. good practice to learn how to make an
engaging digital map to illustrate whatever struggles you might be in."
