lulzbot TAZ 3d printer is dead

by Jake

so i spent all evening (and some of last night) to finally spool up the gigantic pile of black filament for the TAZ 3D printer. i finally got it hung from the wall with a dust cover over it and ready to feed smoothly into the printer, and then i discovered that the heating element in its extruder head is dead. oh well. so, we need a new resistor to go in there. I don't know what the original spec is, but since the whole thing runs on 24VDC and assuming 24 watts of heat, that would be a 24 ohm resistor or so. Is someone other than me interested in contacting Lulzbot and asking whether they want to send us a new resistor, or if they can tell us what part number of resistor we should get as a replacement? -jake P.S. yes i tested the resistor and it's dead, infinite ohms, it's burned out. When we get a replacement we can glue it in there better than they apparently did. If the glue goes bad it dies.

Re: [sudo-discuss] Important Sudo meeting tonight

by Yar

On Wed, Apr 30, 2014 at 3:15 PM, Marina Kukso <marina.kukso(a)gmail.com> wrote: > would someone be willing to catch the list up on what the current situation > is with the omni and what needs to be discussed and/or decided tonight? Sorry for the late reply! There has been a growing consensus that Omni things should move faster than originally planned. At this meeting, we ratified and affirmed the consensus that has been called for repeatedly over the past few weeks: * We affirmed our commitment to the Omni project * In particular, we committed to paying our first/last/deposit to the Omni project * Finally, we decided that should happen sooner than May 15 (the date suggested last week) We did this all with a keen mindfulness towards the process. It was a difficult discussion, but we took into account the text of our articles, all previous conversations in the community, and our human understanding of the situation. We concluded that not only was last night's meeting empowered to make this decision, but it was pressing. The votes were unanimous, with quorums of 12-15 voting members (some people left partway through). Please note this doesn't commit us to particular details or arrangements, only our confidence that those will be worked out. There is still a lot more to decide, particularly with Counter Culture Labs at our unconference/hackathon/thingamabob this weekend, which everyone interested should attend. :)

Hammond Theater Organ?

by Steve Berl

Now that sudoroom is moving to a bigger space, would there be any interest in https://groups.freecycle.org/group/oaklandfreecycle/posts/39254461/Hammond%… If not, perhaps one of the other new residents of the Omni? Thought about it for myself, but don't think I can fit it down the stairs of my house to the music room. It's at Alameda High School, and they'd like to get it out of there soon, but there doesn't appear to be any real deadline. It's a Hammond Concorde, but not sure of the specific model number. Probably needs a bit of restoration (replace some capacitors and fix some broken keys) to make it deluxe, but it could be a really cool addition. If you are interested, please contact serenadietrich(a)comcast.net and jrandell(a)alameda.k12.ca.us. The email address in the freecycle ad is wrong. -- -steve

Additions to the articles of association

by Marc Juul

The following additions to the sudo room articles of association are proposed. They are hereby announced an the mailing list and we will make a decision on whether to adopt these additions at the sudo room meeting on wednesday may 7th. == Section 2.1b Process for becoming a member == * To become a member, a person must submit a brief written or spoken Declaration of Intent to Join where they answer the following questions: ** Why do you want to be a member of sudo room? ** What are you excited about hacking at sudo room? ** What are you excited about sharing with sudo room? * It is only possible to become a member at the weekly sudo room meeting. Prospective new members should attend if possible but can submit a written declaration if they are not able to attend. * At the sudo room weekly meeting, all prospective members must leave the room while the existing members have a chance to bring up any concerns or reasons why the prospective member should not be allowed membership (This shall be referred to as the Initial Pondering). ** The intent is for it to be very easy for new members to join, so only very serious concerns should be brought up. ** If any existing member objects to a prospective new member becoming a member, and this cannot be resolved through discussion, then the prospective member will not be allowed membership. ** Unreasonable or frequent blocking of new members by an existing member is grounds for immediate termination of membership based on a 2/3 vote. * After the Initial Pondering, if there are no objections, the member becomes a partial member, which means that they have all rights that membership confers, except the following: ** The right to participate in decisionmaking at the sudo room weekly meeting. ** The right to throw non-members or sleepers out of sudo room. * Partial members must be introduced to sudo room's values and be given a tour of the space after or during the sudo room weekly meeting where they became partial members, of if they are not present, at their earliest convenience. * New partial members must be communicated to the sudo rooom mailing list within 24 hours, including their Decleration of Intent to Join. * After becoming a partial member, there will be one week for sudo room members to raise objections as to why the partial member should not be allowed to join (This shall be referred to as the Extended Pondering). If objections occur and cannot be resolved through discussion, then the partial member will loose their partial membership and they will be refunded any paid memberships fees or dues. * If after the Extended Pondering there are no unresolved objections, the partial member automatically becomes a full member. No announcement of this change of status is necessary. = Article 5. Empowerment of members = == Section 5.1 Non-member access == * To empower members to deal with problematic non-members: ** Any member may deny non-members access to sudo room assets (and require the non-member in question to vacate the physical space) at any time, with no reason given, unless some other member currently present in the space is willing to vouch for the non-member in question as a guest. ** Before denying a non-member access (and requiring the non-member in question to vacate the physical space), the member must ask both the non-member and the members present in the space if any member is vouching for the non-member as a guest. ** For a non-member, being denied access (and required to vacate the physical space) is not a ban, and the non-member in question may return after 12 hours. == Section 5.2 Domestic Use == The bay area is in the throes of a housing crisis. Despite the abundance of resources (space, buildings, etc), the distribution of those resources is unfair. For many it can be costly and difficult to fulfill the basic human need of shelter. However, sudo room, as a creative community and hacker space, must maintain a division between habitation and usage of the space. As such the following are resolved: * Sudo room is not intended to be used for habitation or domestic purposes. * No-one is allowed to sleep in sudo room at any time. * Any member can require that anyone sleeping in sudo room must leave immediately. * Repeated sleeping at sudo room is grounds for being temporarily or permanently denied access to sudo room's assets, including its physical space.

Website Upgrades

by Matthew Senate

Hey all, I'm working on a series of upgrades for the website. Testing out a new wordpress theme and event management / calendaring plugin on our development site. Please take a look: http://dev.sudoroom.org/ I plan to have www.sudoroom.org direct users to a landing page on this site, with clear donation and calendar information, rather than directing them to the wiki (as it does now). I'll also need a few people to help migrate content, is anyone interested? No coding skills required, just copying old event information into the new event form so we can preserve the historical data. // Matt

Fwd: Price calculations

by Patrik D'haeseleer

I had sent this out to the Omni Logistics group earlier. If anyone would like me to go over any of this at the meeting this evening, let me know... Patrik ---------- Forwarded message ---------- From: Patrik D'haeseleer <patrikd(a)gmail.com> Date: Wed, Apr 30, 2014 at 5:44 AM Subject: Price calculations To: omnilogistics(a)lists.riseup.net Hi all, I've fleshed out my rate calculations for $/sqft of dedicated space, and for use of the shared space. Details are in my spreadsheet and on the wiki: http://wiki.omni-oakland.org/w/Building#Price.2FSq_Ft https://docs.google.com/spreadsheets/d/17DINigEczGwjfTdmdxl-MpYe1KJzJJDeCHR… There's a lot of details, but in the end it boils down to (1) you pay a fixed rate for any dedicated space you'd like to claim (including storage space etc.), and (2) you pay some "share" towards use of the resources of the shared space. I know, this is a big departure from the "offer what you can afford, and ask for whatever space you'd like" approach we've been taking so far. But I do feel we need something like this, to make our pricing scheme fair and transparent. Two big discrepancies, when comparing with how much rent different groups have pledged: - The Cafe covers a large amount of high-quality space - and should be a potential money-maker for the space. However, right now it's only penciled in as contributing $1500 to the rent. - Oakland Nights Live wants to host a large event in the Ballroom once a month, but have only committed to $100 in rent so far. I definitely don't want to pick on these two groups, and I would love to see these be part of the Omni. But it does point out that we need to work with them to make sure that what they propose makes financial sense as well. E.g. If we put a bit more effort into fundraising during the Oakland Nights Live events (even just asking for donations, and/or selling T-shirts), there's no reason we couldn't make these self-sufficient.
