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

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!

Aw it's ok, I wasn't upset. Glad that he is returning to life in some
form, actually. :)
Hey all, I'm trying to build a winch for the 14' projection screen that
going up over the ballroom stage out of a wheelchair motor assembly. Per
Jake's suggestion, I hacked 2 server PSUs to get 24v@14a but the controller
is not working and the error code says the right wheel/motor is missing/not
engaged. Anyone know what I am missing? Do I need to jump something to get
the controller to engage while it is "incomplete"?
Thank you,
robb

Hi there,
Checking in about payment for Sudo Room's rent in April (see attached invoice). I apologize for not being totally in the loop on this, but it's my impression that the Omni agreed to give Sudo a $135.00 rebate on your April rent as reimbursement for paying the Omni's wifi. Is that correct?
If so, please see the outstanding balance on your invoice for April 2015 rent and process payment as soon as you're able. Otherwise, please let me know if any of this is incorrect so I can update your invoice accordingly.
Thanks so much!
Sarah + Finances WG
