Fwd: Biology/Microscope/Programming/Art/Education Hack-A-Thon

by Cere Davis

Hey Folks. See thread below. We have a cool proposal to do a fun cross-disciplinary activity in trying to build DIY microscopes with CCL and Sudo from a talented maker guy from San Jose. Would Sudo be willing to collaborate on this? I, as a sudo member, certainly would. -Cere ---------- Forwarded message ---------- From: Patrik D'haeseleer <patrikd(a)gmail.com> Date: Mon, Jan 22, 2018 at 5:56 PM Subject: Re: Biology/Microscope/Programming/Art/Education Hack-A-Thon To: Thomas … [View More]Zimmerman <tzim(a)us.ibm.com> Cc: info(a)counterculturelabs.org, info(a)sudoroom.org, CCL board < cultlabsboard(a)googlegroups.com> Hi Tom - sounds like a great idea! We do need to cap it at 50 and get Sudo involved as well, since that is our max occupancy for the space that we share with them. I'm not sure info@sudoroom is the best email to contact them though - any Sudo members following this conversation?

We want to attract the same kind of mix of people that go to Sudo and Counter Culture Labs; scientists, tinkerers, DIYs, programmers, biotech professionals, hackers, artists, teachers, educators, and citizen scientists. We will provide about 15 microscopes, 3 different kinds (5 of each); a $20 USB optical with zoom and a wooden adjustable stand, a $10 laser projection microscope and a $50 novel lensless stereo microscope based on the Raspberry Pi (a microscope with it's own OS that runs Python and OpenCV!!!) (https://www.youtube.com/watch?v=SzNjJ8_zT-A and https://www.youtube.com/watch?v=xm750WtlFN0), parts to build and modify these microscopes, some example Python image processing code, links to free imaging tools (e.g. Fiji ImageJ https://fiji.sc/), some hacking materials (cardboard, hot glue, wood), slimy pond water (full of all kinds of tiny fascinating creatures), and samples of plankton from https://www.carolina.com/ Participants are encouraged to bring their own slimy water and microscopic creatures (no pathogens please, my motto is "if you can't drink it, don't bring it" ;). The general goal is for participants to team up and produce something (physical device, code, art work, movie, sound/music, slide show, etc) to help make biology accessible to people using microscopes, code media (art, music, sound, video, image, internet, multimedia), or whatever participants can think of. We are especially interested in plankton; to raise awareness of the complexity, beauty, variety and vital role they play in our well being (they provide 2/3 of our oxygen, are the largest sequester of carbon from the atmosphere, and the baby food for practically every species of fish. However, these are suggestions, as hackers will probably have their own view of what they want to do, which is the point of holding a Hack-a-Thon, to encourage creativity and experimentation! FYI I'm a hacker/inventor myself and spend a lot of time going to schools to turn kids onto STEAM (https://makezine.com/2009/06/ 23/make-contributer-thomas-zimmerman-h/ ) Regards, Tom Thomas G.

I just purchased two refurbished 20 megapixel Canon PowerShot ELPH 160 and the archivist lighting assembly which includes LED bulbs, sockets, lenses, wiring and power adapter. Jonathon will send us the design files for the sockets mounting plate soon as I tell him what format we need to cut it at the SUDO room: DXF or SVG or something else? ~ http://diybookscanner.org/archivist/index6ea9.html?page_id=267 This is the page describing the plate.

Re: [sudo-discuss] vending machine homing switch mystery solved

bump! does anyone want to help get one or both vending machines working? This would be a great way to vend arduinos, ESP8266's, candy bars, and whatever else we want to sell to sudoers and others.

I read the Articles of Association

by Captain Chesapeake

Hi all, I'm a new member. I'm excited to be a part of this community. There are great people and great resources in the space. I've also noticed that is kind of disorganized, cluttered, and the organization is broke! As a medium to long term goal I think it would be great to gain financial solvency and be able to start saving for larger projects as well as clean up the space and make it an amazing workspace with lots of working tools, spare parts, and workspace. I reviewed the articles of … [View More]

Stripe Subscriptions

by Kyle Mitchell

Following on from the finances discussion during last week's meeting... On manual review of our Stripe account, I see 36 monthly recurring dues subscriptions through sudo-humans for a total of $1,290 per month. There were a handful of accounts with failing transactions. (This tends to happen when a card expires or a number changes.) However, those accounts probably add up to <$100 per month altogether. If we expect, say, $1,200 per month actually paid, and our sole bill is to Omni, for $… [View More]

Treasure or trash?

by Ed Biow

Folks, a crony gave me a 6+1 DVD duplicator and a couple of external firewire DVD-RW burners, plus a laptop cooler pad dealer (see attached picture). Maybe we could use the duplicator to burner videos of an event in the ballroom for quick distribution. I have a few spools of DVD-RWs I could throw at it. Otherwise this stuff just goes in my e-cycling pile, though I have to say it does make a pretty cool electronic samurai sculpture in my living room. https://www.amazon.com/s/ref=nb_sb_noss?url=… [View More]search-alias%3Delectronics&fiel… Edlardo -- +++++++++++++++++++++++++++++++++++++++++++ If God is watching us the least we can do is be entertaining.
