Intro to Beekeeping at OMNI Collective - Counter Culture Lab

by Alice Rosenthal

INTRODUCTION TO BEEKEEPING CLASS Once you’ve had a fantastic romantic Valentines day - You’ll be ready to get moving forward on your new years resolution to “Keep Bees”! Don’t worry if you don’t have a place to keep them - you’ll get lots of creative idea from this lecture. Yes, this is the place to start. Come ready for some fascinating facts about our most important agricultural helper, and learn what you need to know to get going. Wear comfortable clothes - they make you feel better, but don’t wear wool or perfume as they make honeybees aggressive. Save the Date: February 15th, 2015 1pm - 4pm (perhaps later) Save the Location: The Omni Collective: Counter Culture Labs 4799 Shattuck Avenue,Oakland, CA Make a donation to cover the cost of life: $35 suggested. RSVP’s appreciated: BeeHappySolutions(a)gmail.com <mailto:BeeHappySolutions@gmail.com> Come by bicycle, bus or car - street parking is tough. Bring Snacks made from anything made by the help of a bee. I’m going to bring some accidentally fermented honey wash water.

Help design a circuit for sudoroom's hardware hacking tuesdays!

by Jake

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! -jake On Sat, 31 Jan 2015, Patrik D'haeseleer wrote: > Sounds like we should come up with a little electronics kit that uses as > many of these as possible, and then sell or give them away as soldering > 101 kits. > > Patrik > > On Jan 31, 2015 1:39 PM, "Jake" <jake(a)spaz.org> wrote: > 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 > a thousand NDT3055L general purpose NPN transistors > a thousand LM1877 audio amplifier chips > hundreds of LM1881 video sync seperators (for overlaying text on video!) > 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... > _______________________________________________ > sudo-discuss mailing list > sudo-discuss(a)lists.sudoroom.org > https://lists.sudoroom.org/listinfo/sudo-discuss > > >

electronics donation!!!!!

by Jake

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 a thousand NDT3055L general purpose NPN transistors a thousand LM1877 audio amplifier chips hundreds of LM1881 video sync seperators (for overlaying text on video!) 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: [sudo-discuss] sudo-discuss Digest, Vol 27, Issue 27

by Oren Beck

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&amp 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:> HtH Oren Beck

Re: [sudo-discuss] TV IV

by Ed Biow

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. e - > Message: 26 > Date: Thu, 29 Jan 2015 12:54:43 -0800 (PST) > From: Jake <jake(a)spaz.org> > To: sudo-discuss(a)lists.sudoroom.org > Subject: Re: [sudo-discuss] TV IV > Message-ID: <alpine.BSF.2.00.1501291250020.62936(a)pe2950.spaz.org> > Content-Type: TEXT/PLAIN; format=flowed; charset=US-ASCII > > Hi Ed, > > the flatscreen TV mounted near the 3d printers says it works but i have > never tried it.

Replace Sudo elec outlets with GFI

by David Keenan

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?

Re: [sudo-discuss] TV IV

by Jake

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. -jake On Wed Ed wrote: > I know we have a couple of broken TVs in the sudoroom.

Show high school seniors what a hackerspace is

by Karissa McKelvey

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? -- Karissa karissamck.com 'The kids call me Special K. Hopefully they just think I'm special'
