The vending machine now provides some more feedback after money is put in.
Source code associated with my contribution is here. I haven't documented
the other components of the vending machine.
Based on the implementation details, it appears to me that
the bill acceptor is in fact plugged into one board (Arduino Leonardo)
that is connected by serial to another board (Raspberry Pi). Why is
the former board used at all? That is, why is the bill acceptor not
plugged directly into the latter board?
I said "your 'community' space," but honestly, I still want this to be my
space, too. I hardly ever make a fuss about any of this stuff because it's
all so futile, you know? but in this case, I really want to make my point
clear: I think we should rescind our action against Rannette. I think
she's been treated unfairly. Even if she is "aggressive" towards you or
your compatriots, I don't think we need white dudes policing our space of
black women's bodies. Matt, you claim to have acted in another's interest
and you offer an injured third party -- let them speak for themselves,
because I don't think it's your place right now. If there was a violent
incident that threatened our space, let's hear it from a witness or an
involved party. "Something Happened" is not good enough. Otherwise "but
above all the Omni
Commons must maintain a safe, welcoming environment" seems to fly directly
in the face of the lived experience of too many black people.
I wanted to reach out for some feedback. Seeking folks who would want to
facilitate or participate in a men's group.
I've previously participated in small groups like this and found them
beneficial for various reasons. I would like to see if folks have had
similar or different experiences.
The way I'm thinking about this would culminate in something like a regular
meeting for men in the sudo room community to discuss relevant issues
including those of identity, oppression, privilege, patriarchy, gender,
sexuality, stereotypes, safe space, and mutual support.
This may not be the best or even a viable path to approach these topics,
but I wanted to throw it out there to see if there is any interest.
Here's some images of the Seiko SMI 3200 Scanning Electron Microscope that
is in need of a new home:
Note that this is NOT a small system! It's not huge as SEM's go, but
definitely not desktop - more like "small room sized". And it would
obviously need some dedicated person to keep it in good running condition.
It is however almost brand new, and currently *running*, at <5nm resolution!
Beam Services Inc is down in Pleasanton, so I guess interested parties
could potentially go and have a look at the system. This kind of equipment
would be a significant commitment and investment in time and effort on our
part, so let's coordinate on this shall we?

Nope, just finding a good adhesive for reattaching it is hard. I ended up
just using an open cell foam pad to push the header on the glass
Only advice is to not be too aggressive and let the glue take its time to
release. Doingbot while warm would help.

Cool! Hey is there any reason why I can't do that end then just flip the

Any tips on getting the heating pad off?

Henner wrote this awesome parts organizer web service, and it's running at
noisebridge (and his house):
here's the noisebridge implementation (type a letter to begin instant search):
i would love to help fill it with information about the stuff we have at
sudoroom, but i am not confident in my ability to install it and get it running
on our network. If someone feels good about doing this, sudo make it happen
and i'll help.
Lack of email reminders to members has been an issue for awhile now.
It occurred to me that perhaps this was just a Stripe setting - seems it
So now members will be notified by email when their payment fails, and
notified 1 month in advance of an expiring card.
Is this problematic to anyone?
CC'ing some CCL folks who've mentioned this before.

Checked across several devices, the Omni Commons ssid is not available. No
one present knows how to fix it. Any help appreciated.

There was a (neighborhood wide?) power outage this morning.
Unfortunately, after power came back online, WiFi did not. There is no Omni
Commons ssid available (I checked in several locations through the Omni).
Also unfortunately, nobody present knows how to resolve things.
FYI, in case relevant, I believe that (internet access via) the modem came
back online after the outage (because the relevant lights on the modem seem
to be flashing correctly, as far as I can tell.) I've been told (but have
not verified) that (at least some) wired connections here do have internet
This Saturday, come join us for a whole day workshop (8am to 8pm!) on
building a 3D printer at Counter Culture Labs, with some of the folks from
Open Source Ecology.
Build the open source 3D Printer with the lowest part count in the world.
Learn about 3D Printing with step-by-step guidance in a supportive
To support Counter Culture Labs, this workshop hosted by Open Source
Ecology is $10 recommended, but no one turned away due to lack of funds and
free to participate (please register using the link below). Walk-ins are
very welcome, especially if you're curious and want to swing by for a few
hours or less -- Open Source Ecology wants to share something new and
impressive with you. Register for FREE here:
We’ll show you step-by-step how to build this modular design in an
accessible and straightforward way. You’ll appreciate how an open source 3d
printer is designed and experience how teams can work together to build
something amazing, even if they’re novices. Each team takes a 3D printer
home to their community that they can use to build community-scale
infrastructure or make 3D printed objects.
To take a printer home, the price is $799. Compared with other open source
3D printers, ours can be built with off-the-shelf parts and our part count
is half the others, making it easier to understand, build, and maintain.
Because it is part of the Global Village Construction Set (for more info,
please watch our founder's TED talk here:
https://www.ted.com/talks/marcin_jakubowski), the OSE 3D printer is
designed to scale and handle industrial production, which means if you want
to some day build a 3 foot printer, this is the printer for you.
Additionally, every CAD design of the 3D printer is available in its
entirety, so if you want to change out printer heads to print something
other than PLA or ABS plastic, our design makes this process significantly
easier, especially because we have a 300 page manual to support builders
and a process to continually improve documentation.
Claim your 3D printer TODAY for 1 of 2 possible builds by registering here:
The event runs 8am-8pm. Specific timing depends significantly on how we
progress as a group but generally we follow a timeline like this:
8am: Introduction. Applications of the 3D Printer Construction Set.
9am: Morning Build Session
1pm: Afternoon Build Session
6pm: Printer Calibration & First Prints
7pm: Review and Learning Discussion
8pm: Event ends
Registration secures your placement in this workshop to build and take home
a 3D Printer. Participants are welcome to bring along one or more persons
to share in the educational experience and assist the build for no extra
cost. The workshop is a fast-paced collaborative experience and goes well
with many helping hands!
