Riotcon? Who's interested

by Gregg Horton

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

NOT OK TO SELL YOUR USED BIKES OR PERSONAL ANYTHING OUT OF OMNI

by David Keenan

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: https://sfbay.craigslist.org/eby/bik/4601012296.html Best, David ---------- Forwarded message ---------- El Aug 3, 2014, a las 4:05 PM, "craigslist 4601012296" < xn5xw-4601012296(a)sale.craigslist.org> escribió: 4799 telegraph ave oakland 94609 On Sunday, August 3, 2014, @reply.craigslist.org <86cc4e37f2973e19bfa50720b2d8d4e0(a)reply.craigslist.org>> wrote: > Ok me puedes mandar la dirección para ir por ella gracias > > Enviado desde mi iPad > > El ago 3, 2014, a las 3:49 PM, "craigslist 4601012296" < > xn5xw-4601012296(a)sale.craigslist.org> escribió: > > Tengo > > On Sunday, August 3, 2014, @reply.craigslist.org> wrote: > >> >> hi I'm interested in the bike still has it? >> >> http://sfbay.craigslist.org/eby/bik/4601012296.html >> >> >> Enviado desde mi iPad >> >> >> ------------------------------------------------------------------------ >> Original craigslist post: >> http://sfbay.craigslist.org/eby/bik/4601012296.html >> About craigslist mail: >> http://craigslist.org/about/help/email-relay >> Please flag unwanted messages (spam, scam, other): >> http://craigslist.org/mf/31cae89e329e4ffdb4f5485f9ad55f382a5e4554.1 >> ------------------------------------------------------------------------ >> > > ------------------------------ > Original craigslist post: > http://sfbay.craigslist.org/eby/bik/4601012296.html > About craigslist mail: > http://craigslist.org/about/help/email-relay > Please flag unwanted messages (spam, scam, other): > http://craigslist.org/mf/2aa1160e237c2864d20f445caec61d39079b378f.1 > ------------------------------ > > > ------------------------------ > Original craigslist post: > http://sfbay.craigslist.org/eby/bik/4601012296.html > About craigslist mail: > http://craigslist.org/about/help/email-relay > Please flag unwanted messages (spam, scam, other): > http://craigslist.org/mf/2b2381e132cef1f151594e398fde8988ba67f2d7.1 > ------------------------------ > > ------------------------------ Original craigslist post: http://sfbay.craigslist.org/eby/bik/4601012296.html About craigslist mail: http://craigslist.org/about/help/email-relay Please flag unwanted messages (spam, scam, other): http://craigslist.org/mf/28b28db4b10e78e275c6498788a67c92ce95aa36.2 ------------------------------

Re: [sudo-discuss] welder in sudo room

by Jake

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. http://www.youtube.com/watch?v=osErRS4m4S8#t=55 -jake Hol wrote: 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.

robot repair

by Jake

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? -jake

robot encoder data format

by Jake

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. ------ forwarded message ------- 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.

Fwd: [sfchalkboard] DEEP WEBSITE HELP

by Vicky Knox

Any takers? Here's the original post with contact info: https://lists.riseup.net/www/arc/sfchalkboard/2014-08/msg00002.html ---------- Forwarded message ---------- Date: 2014-08-01 12:56 GMT-07:00 Subject: [sfchalkboard] DEEP WEBSITE HELP To: sfchalkboard <sfchalkboard(a)lists.riseup.net> 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! -- *+whatever it takes+* STRIKE DEBT BAY AREA http://strike-debt-bay-area.tumblr.com FEMINIST REPRODUCTION W/ 3-D PRINTER http://wemakemeteorsnotmoney.tumblr.com POETS' SECURITY FORCE www.poetsecurity.net
