Reminder -- Wikipedia/open education barn raising tomorrow!

by Pete Forsyth

Hi Sudo folk, I know there are some wiki people out there -- wanted to remind you of this (free) event tomorrow. We'll be working on Wikipedia articles about open education, and similar topics. Please join if you can -- and if you sign up tonight, we've got your lunch covered :) It should be a great way to flex your wiki writing muscles, and meet people interested in hacking education. We'll have online participants joining us from all over, as well! But join us in person at the Impact Hub, on 23rd and Broadway. http://en.wikipedia.org/wiki/WP:OERBARN Pete [[User:Peteforsyth]]

Activities in CCL space

by Patrik D'haeseleer

Hi all, Just a heads-up that between now and Friday, the landlord will be sending in some movers to take out all the desks and other crap that he left behind in the Counter Culture Labs side of the hall. (Not sure if the big pile of doors in Sudo should be moved out at the same time?) I know that some Sudo gear keeps migrating into CCL's space, but I would strongly recommend that you keep your gear well away from the stuff in our side that needs to get moved out, or at the very minimum keep it clearly labeled, so the movers don't accidentally toss it out as well. After all of John's stuff is gone, we will likely want to clear most everything else out of CCL and do some serious cleaning, painting, and floor sealing, so we can actually start turning the place into the citizen science laboratory it's supposed to be. If you have any chemical sensitivities, or suggestions for what types of products to use (or not to use), now would be a good time to speak up... Looking forward to hack some science with y'all!

safe space logistics - code of conduct & respecting omni bans

by yar

I think there are two things we should do to augment our safe space logistics 1) We should adopt a code of conduct for Sudoroom and all events that we sponsor. I think we should look at the Geek Feminism CoC: http://geekfeminism.org/about/code-of-conduct/ Please read it through if you have the time. 2) We should agree to honor all bans on people by other groups and spaces at the Omni, AND by the Omni itself. The Omni hasn't yet required this of groups, and doesn't yet have its own structures in place for banning people from the common areas, but we can still be proactive until that happens, and I think doing so would show good faith to our Omni community and help convince everyone this is a Good Thing. thanks, Remote Yar

Re: [sudo-discuss] robot arm for sudoroom

by Arnas Lucassen

I also think this might run into some serious safety and or space issues. But I am in for $20-50 if used responsively.

Hardware for the masses

by Ed Biow

My crony Gerald & I picked up about 15 'puters from Youth Radio <https://youthradio.org/> today, and brought them to the sudoroom. We also grabbed about 7 monitors and a bag full of cables. These boxen look pretty sweet, dual core, Windows 8, 4 GB of RAM. I was planning on installing some version of Trusty Tahr (*buntu 14.04) or maybe Debian testing and then using a live disc (redobackup <http://redobackup.org/>) to blow the image on the rest of the machines after testing the memory and hard drives. Brian, the IT bloke at YR is replacing the machines with NUC <http://en.wikipedia.org/wiki/Next_Unit_of_Computing>s. It looks like there are another 30 or so of these Dells available to us when they get readied. If we can spare the table space maybe we can set up a few machines for visitor browsing in a quiet corner somewhere. And we should have some nice boxes for the Oakland kids' computer center. The four boxes I have ready to go are mostly pretty funky, missing panels, or very loud, etc. I'm sure we can find them a home, though. I also have a few more expendable desktop Linux machines at home. Finding rodents, power cords, monitors & keyboards may prove a bit of a challenge, though I have a few extra keyboards and power cables. I'm planning on going camping in August, but in September I'd like to start hosting a weekly Linux install fest/trouble shooting session on Friday afternoons at 4 PM. Folks can bring their Linux problems in for troubleshooting, and I can bring pizza back from a pickup I make at 8PM from a local collective. Maybe if nothing else is going on we can cap the evening with a tech/polit-related flick to go with the pizza, perhaps even a round of frosty malted beverages. As I mentioned before, maybe we could use some always-on machine to act as a proxy for deb files, so we could update machines at 11MB a second instead of pounding our limited internet bandwidth. I'm familiar with approx and apt-cacher, though there are others. I'll bring up the idea during one of our weekly Wednesday meetings soon. Einstein & campaign staff

robot arm for sudoroom

by Jake

tl;dr can we put this giant robot arm at sudoroom? http://spaz.org/~jake/pix/giantrobot 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. here are a couple Motoman robots in action: http://www.youtube.com/watch?v=e904eHn8MDI http://www.youtube.com/watch?v=IQQlbx2S-j4 loading ikea shelves: http://www.youtube.com/watch?v=Duub_dO_TwU 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 :( here are the strings found inscribed on its surfaces: Motoman TYPE: YRFL-NNA10GB LIFTING CAPACITY: 10kg WEIGHT OF MACHINE PROPER: 300kg SERIAL NO.: RH9972-0064-13 ORDER NO.: 304438-1-1 DATE: 1990 YASKAWA ELECTRIC KITAKYUSHU JAPAN YASNAC ERC TYPE: ENCM-RP6124 POWER SUPPLY: 200/220V 50/60Hz 3 PHASE 8 KVA SERIAL NO.: RPN789-051A-4 DATE: 5-1990 P/N.: 774 YASKAWA Electric Mfg. Co. Ltd. JAPAN WARNING: DO NOT SUPPLY POWER TO THE 'YASNAC' BEFORE FIXING THE ROBOT BASE. OTHERWISE THE ROBOT MAY FALL DOWN. WARNING: DO NOT OPEN THIS DOOR EXCEPT FOR MAINTENANCE OF 'YASNAC' DO NOT CONNECT OR DISCONNECT ANY WIRING, CONNECTORS AND RELAYS WHILE POWER IS ON. WARNING: DO NOT ENTER THE ROBOT'S WORKING AREA / WHEN THE POWER IS ON. WARNING: USE TWO EQUALLY LENGTHENED WIREROPES AND HOOK THE ROBOT UP WITH TWO EYEBOLTS. REMOVE THE CLAMPS (A) AND (B) BEFORE TURNING POWER ON.

Door Access Broken

by Andrew

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 system. Thanks, Andrew -- ------- Andrew Lowe Cell: 831-332-2507 http://roshambomedia.com
