after you guys left i got both X and Y axes working properly, in the correct direction, and the endstops too! now i was even able to home it! here's the repo: https://github.com/sudoroom/Marlin/tree/quickcircuit marlin can be uploaded with regular arduino, it's an arduino mega 2560 we still need to enter the correct values for stuff like DEFAULT_AXIS_STEPS_PER_UNIT DEFAULT_MAX_FEEDRATE DEFAULT_MAX_ACCELERATION although really only the first one is necessary. then we need to either find a … [View More]

Sourcing <= 50 micrometer ETFE film

by Marc Juul

I'm starting to play around with electrowetting (specifically the OpenDrop) and I'm having trouble finding a source for extruded ETFE film of a thickness of at most 50 micrometer. Any ideas? Anyone have experience with ultra hydrophobic coatings or spin coating? -- marc/juul

bicycles and parts gathering in sudoroom

by Jake

there is a bicycle frame without wheels, a fender, and five wheels and three tires floating around sudoroom, as well as two bicycles that do not belong to anyone who is here right now. I don't think people should be using sudoroom as a place to store their vehicles, and large projects like bicycles should not be stored here except for very limited situations like a project that takes more than one day. People have been working very hard on cleaning up the space and the electronics waste pile … [View More]

Event this Saturday: 4Love, Science and Liberation

by Julio Rios

Hey Commoners, I'll be helping out with this event Saturday morning 10am-1pm. stop by the ballroom if it sounds interesting to you. How can science be used as a tool for liberation? Scientists and community organizer, Kendra Krueger, guides us through a process of reclaiming science as a tool for personal and social liberation. We’ll take a look at decolonizing the language of our current scientific paradigm and exploring the intersections of science, social justice, art and intuitive … [View More]

Re: [sudo-discuss] #5MoF?

by Jenny Ryan

Great idea, Charley! Sudo Mesh has been doing quarterly workshops and it's been really effective. Gives us time to plan a schedule and promote widely, and lotsa members show up and help with various facets of the event because we divvy up the work and people commit to specific roles (eg; A/V, chairs setup, welcome table, presentations, intro, food, promo/flyering, stickers/swag). I think 5moF facilitation has been hard because it seems like all the organizing work is pretty much on one … [View More]

surface mount electronics donation

by Jake

personally i think we should accept those parts, but we've been getting rid of a lot of unnecessary stuff from sudoroom recently (well mostly not me doing it) so anything that we get from them that doesn't belong in sudoroom will get recycled if nobody else wants it. I will say that the last stuff we got from them seems to be pretty decently useful, most of it, so that's a good sign. I don't think we want the carousels though, they seem like the kind of thing you use in a factory where you … [View More]have plenty of space and need random access fast, whereas we are only going to survive in sudoroom if we can store stuff densely and compensate by keeping good records of where stuff is parked. -jake On Wed, 26 Jul 2017, Patrik D'haeseleer wrote: > By the way - I may be able to get a bunch more surface mount components, > from the same lab from which I brought over several boxes full of spools > before.
