A lot of conversations are still happening. We're going to have even
more conversations at tomorrow's hackathon. Look forward to seeing you
there. :)

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 …
[View More]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.

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 …
[View More]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. :)

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 …
[View More]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.

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 …
[View More]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.

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 …
[View More]copying old event information into the new
event form so we can preserve the historical data.
