I have always loved the idea behind Circuit Hacking Mondays, which happens
at Noisebridge every Monday for the past n years.
Sudoroom will be having Hardware Hacking Tuesdays from now until t, and we
need to come up with some stock kits for n00bs to put together to learn
how to electronics!
seeing as we just got a huge donation of stuff (listed below) I say we
come up with something that uses these excellent, FREE recycled components
that would otherwise end up in a landfill or our lungs. It helps greatly
that the components just happen to be perfect for...
DIY micro-music synthesizers!!!
picture this: a kit you can put together at sudoroom which, when you're
done, makes awesome musical sounds and maybe sequences with a bunch of
dials to turn and buttons to push.
your mission: design a cool kit using the parts we have plenty of! the
winning designs will be made into actual circuitboards sent out for
fabrication and zillions of people will build those kits!
we have unlimited potentiometers (board-mounted with a long enough shaft
to turn with fingers)
unlimited board-mounted buttons (four-pin, either SPST or DPST)
unlimited piano-style DIP switches (two and eight positions)
unlimited op-amps (250MHz bandwidth OPA354 i believe)
unlimited 74HC14 schmitt triggers (six oscillators of any frequency)
RCA jacks, headphone jacks, LM1877 audio amplifier chips
and all the resistors and capacitors you could possibly need
your design should not include a microcontroller, just passive parts that
go together and make noise. Input will be 5 volts DC, output will be
line-level audio for going into amplified speakers.
we have lots of logic chips like 74HC163 four-bit counters and 74AC351
8-input multiplexers - so it should be easy to add a sequencer to your
design!
if you have plug-in breadboards, bring them in, it will make it easier to
prototype this stuff.
see you on tuesdays!

yesterday I brought a pickup truck load of electronics to sudoroom:
20000 20000 ohm pots
20000 board-mount buttons
thousands of op-amp chips
boxes of RCA jax and headphone jax
hundreds of 87c52 microcontrollers...!
spools of surfacemount capacitors and resistors (mostly 0805 size)
1,000 74HC14N (for hex oscillators!!) and lots of other interesting chips
thousands of 25V lectrolytix 220 470 1000uF

rails and rails of DIP switches (piano style, 2 pos and 8 pos)
many assembled circuitboards with cool stuff on them, including FPGAs!
boxes and boxes of 4x6" backlit monochrome LCD displays...
what should we build with all this stuff?
now i gotta design a board that uses those things to make music for a
hardhack tuesdays kits...
Re: Replace Sudo elec outlets with GFI
I may be able to lower the Drama Levels by suggesting that folks Hardware
Hacking on mains voltage use a WAY LOWER amp breaker for their Hackery;
http://www.allelectronics.com/make-a-store/item/cb-1605/5-amp-push-to-reset…
Either shell out a few bucks to buy one& slap it into a power strip... or
scavenge a similar/lower rated one from some scrapworthy device. Idea is-
the 5er or lower will pop WAY before risking anyone else getting shut
down. I had a "test box" with Variac. volt& meters and switch
selectable breakers from 1/2 to 15 amps for test/hacking and it saved a lot
of headaches let alone preventing damages:>

Hey, all the boxes on the main table of sudo, a MESA donation by Jake, is
beig sorted nd put away, and as it goes heres a preliminary inventory of
whats going on with it.
Hi there!
See below for a link to Sudo Room's invoice for January's shared expenses
at the Omni. Take a look and let me know if you have any questions.
For your reference, here is the breakdown of the Omni's
total expenses (utilities, taxes, & insurance) from this month:
- PG&E: $691.74
- EBMUD: $390.09
- Waste Management: $60.21
- Building Insurance: $660.00
- General Liability Insurance: $188.16
- Director's & Officer's Insurance: $302.00
- Taxes: $595.62
The utilities are split evenly between member collectives and tenants. All
of our taxes and insurance are shared between member collectives only.
Let me know if you have any questions, and please pay Sudo's portion of
the shared expenses as soon as you're able.
Thanks and <3,
Sarah + Omni Finances WG
Below please find a link to Invoice #132.
Amount due: $433.72 USD
Due by: 2015-02-01

No Jake, that TV has a big green stripe going through the middle. From
what I've read on the web it might be something we can fix by mucking
with/cleaning connections, but it is probably new panel time, which is
unlikely to be worth the effort with a box of that vintage. I'll schlep
in the TV I have & the mount.

Hey all,
Someone was experimenting with electrical stuff and tripped breakers...
I think Sudo's standard outlets should be rewired with GFI outlets if this
will cut down on this happening -
I will volunteer to replace these with one other who knows electrical
(Whitney? Jake?) if it can be budgeted. Is this agreeable to folks?
Hi Ed,
the flatscreen TV mounted near the 3d printers says it works but i have
never tried it. I will try it and determine whether it's ewaste or not.
there's another huge display that RAYC was playing with, we should do the
same thing. I think it would be nice to have several working mounted
screens around.
As for the one you are offering, I think you should bring it in, and it's
great that it has a mount because we should put it up right away.
I am excited to have more of this type of infrastructure in sudoroom
because i think there are a lot of limitations to projectors that can be
overcome by having screens like this around.

Hey sudoers
I'm teaching a web programming class of about 20 high school seniors
(17-18 years old) who live in Oakland. They are primarily people of
color and underprivileged in some way, having reached hardships enough
to find themselves at a continuation high school due to bad grades.
I'd like to bring them on a fieldtrip to sudo room/omni for an hour or
two so they can see the tech, get a tutorial on 3d printers & see one
in action. Maybe if people wanted to show off their projects they're
working on, that'd be cool too!
Anyone interested in this sort of thing?

'The kids call me Special K. Hopefully they just think I'm special'
hey sudoers,
I met a guy named Chris Shaw about a week ago. He is the second person
I've met at the omni who came through because of the East Bay Express
article!!! (:
Chris wants to know if anyone wants to talk with him about the code he's
developed for auto-animating emotions and speech in CGI characters. It's
basically the next level in creating virtual CGI people with very flexible,
self-generating behavior: applications include NPCs in video games (of
course), next-gen conversation bots like AIM's SmarterChild back in the
day, and even therapeutic tools to help autistic children practice emoting.
http://vimeo.com/113120097http://vimeo.com/113571986
the same tech can be used to animate animatronic robots.
He's looking for collaborators to develop applications for this tech. If
anyone's interested in playing with the technology or has questions for Mr.
Shaw, you can contact him at: xophershaw(a)gmail.com !
Howl,
