Friends,
There have been some issues over the last few days with people disrupting
the space, that it has become necessary to restate the access policy of the
Omni.
During the hours that La Commune is open (Tue-Sun 12-6pm) the bookstore is
open to the public. Outside of those hours, the Omni is NOT open to the
public and the door is to always be shut closed, not latched open. During
those closed hours, the Omni is open to members of collectives, or to their
guests who must be accompanied by members at all times. During events,
such as BAPS classes, the point person for the event is responsible for all
the participants who are not members.
Other volunteers are working on door access tomorrow at noon if anyone
wants to help make the building more conducive to having a safe
environment.
Love,
Julio
if sudoroom wants the omni to continue to exist, we will need to all get
on-board to keep this boat afloat.

Subject: [omni-consensus] !! Financial announcement !!
Hi friends,I'm stuck at work and probably won't make it to the delegate's meeting tonight, but I wanted to make an announcement about the Omni's
finances.
As many of you know, the Omni has been running a monthly deficit of about $8,000 - $9,000 every month. We've been able to make up for that by dipping
into the funds raised in December through the Indiegogo campaign, but those funds are running out quickly.
We currently only have enough $$ in the bank to cover two months of rent and expenses. Member collectives can do your part by paying invoices on time
(and even early if you're able!) for the next few months. If your collective has outstanding invoices for rent and shared expenses, this would be a great
time to appeal to your members for extra support so you can pay any $$ still owed to the Omni.
The finances working group has been updating our Quickbooks and will soon be able to present more detailed and thrilling financial reports so everyone
will have a clearer picture of where the Omni's money is coming from and how it's being spent.
Better data = more lucid decisions.
Let me know if you have any questions about this. The next finances working group will be held on Wednesday, July 22 at 7 pm at the Omni. Come hang out
with us if you want to learn more about Omni $$$.
xxxxooo,
SP
One of the video documentary people who were visiting us during the cheese
making workshop at CCL this Monday lost a black backpack with 2 Canon
lenses, his ID and credit cards.
If anyone saw it, please let us know!
Thanks...

Hi again,
In addition to the outstanding rent invoice for April, please see the attached invoice for shared expenses at the Omni in April. It would be great if you're able to pay at least part of this invoice as soon as possible.
The Omni is in a precarious financial situation currently so I'm asking all member collectives to pay outstanding invoices if they're able.
Let me know if you have any questions.
Thanks again,
Sarah
------------------------ Invoice Summary --------------------------
Invoice # : 1013
Invoice Date: 03/25/2015
Due Date: 04/01/2015
Terms: Net 30
Amount Due: $513.55
The complete version has been provided as an attachment to this email.

if you put a 1 ohm resistance, you will just blow up the resistor.
24 volts divided by 1 ohm = 24 amps
24 volts times 24 amps = 576 watts
you need to find the highest number of ohms that will still cause the
motor controller to not give you an error. Lets say you find that a 100
ohm resistor (in place of the missing motor) causes the controller to be
OK. When you move the joystick, and it tries to turn the fake motor, it
will give it up to 24volts. But it's a 100 ohm resistor.
24v / 100 ohm = 0.24 amps
24v * 0.25 amps = 5.76 watts
if it works with a 100 ohm, you should use that. 5.76 watts is
reasonable. 576 watts is most of a horsepower and is not reasonable.

in case you're not confused i'll tell you this: the power a motor
consumes (from a fixed voltage source for example) depends on the amount
of force it's putting out.
So if you have a motor just spinning a wheel in the air it doesn't take as
much power as if you're making it grind grain, or push a fat person up a
steep incline. The ohms you measure when you use a multimeter on the
stopped motor correspond to its MAXIMUM power, basically.
so if you stopped the motor and applied 24v, 576 watts would flow through
it and heat it up pretty fast. But if you let it spin freely in the air,
its effective impedance would be much higher than 1 ohm!
as for how to isolate the motors for different jobs.. we can read the
manual on the control box and adjust the settings, or just hook up the
computer control and let it do all the work. I don't know though.

Wait, are you talking about ... MC Hawking? Is MC Hawking being
reassembled into a movie screen??

Subject: [omni-discuss] Important Omni meetings in July
To: "discuss(a)lists.omnicommons.org" <discuss(a)lists.omnicommons.org>
Friends,
*There are 3 important meetings coming up in July that we need people who
support the Omni to attend**.*
On Thursday 7/16, at the regular delegates meeting, several proposals
will be discussed along with
information about David Keenan's sabbatical from the Omni.
On Thursday 7/23 at 7pm we will meet to update the community about
progress being made towards buying the building. Options for how to
structure the purchase and ownership will be presented and discussed.
Thursday 7/30 we will be holding our official Annual Board meeting as
required by our bylaws. New officers (President, Treasurer/CFO,
Secretary) will be selected. Currently Lara Durback is willing to be
President, Sarah Pritchard has agreed to be Treasurer, and Jenny Ryan
is willing to continue as Secretary. If you have an interest in
serving in any of these roles, let us know. Also, per our bylaws,
*each member collective must officially designate a delegate** at the
annual meeting. **Each collective should choose a delegate according
to its own internal process before th**e meeting.
Please forward this email to your collectives so we can have as much
participation as possible.
*Thanks,
<3
Laura

Hi all,
There's a cool event based in Uganda, but designed for remote
participation, this weekend.
"Outernet" is a project to repurpose satellites to "broadcast" free
information, that can be picked up by inexpensive receivers, for free, and
then reshared for free over local networks/WiFi. A way to get information
to remote and underserved parts of the world. It's one-way communication,
so certainly not a replacement for the Internet or a total solution to the
Digital Divide -- but a very cool project nonetheless. They are also
developing democratic processes for deciding what content to share.
They are having an edit-a-thon this weekend. I thought Sudo folks might be
interested. Keep in mind, this is 10am to 10pm Uganda time -- which
midnight to noon Saturday Pacific (I think it's the same hours Sunday, need
to confirm).

And see their blog post:

If anybody would like to pass this along to Noisebridge or other lists that
might be interested, please do!
