Does anyone have “double conductive” copper tape?

by Cere Davis

…Where the adhesive is conductive. I just need to have a small piece. I have some on order but have a time pressed project I want to move forward on. Thanks, Cere -- *Cere Davis* Science-Art/Kinetic Sculpture CereDavis.com @ceremona <http://Twitter.com/Ceremona>

Moar (useful) SMDs you say?

by Morgan Allen

Picking up several boxes of surprisingly well organized, not predominantly R/C smds. Anyone around to help me unload shortly?

solenoid wanted for sudoroom circuitboard CNC machine

by Jake

does anyone on this list have a solenoid? something that can pull a pound or two of force, from a distance of 1/4" or more, ideally. 12-24 volts would be great, although we could do 120V if necessary. thank you -jake On Wed, 2 Aug 2017, Alexander Papazoglou wrote: > Awesome! > > Any response about the missing solenoid?

quick circuit 5000 is almost working

by Jake

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 solenoid or use this servo to do the Z axis, and configure marlin to control it appropriately from a Z command or whatever Z instruction gets produced by stuff like PCB2GCODE -jake

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

Fwd: Join us for Microscopy 101 & 401 class at CCL Sat morning!

by Patrik D'haeseleer

*Join us for our Microscopy meetup tomorrow morning at CCL <https://www.meetup.com/Counter-Culture-Labs/events/241864024/>! *We'll have something for newbies and experts alike... We'll give a tour of the microscopes we have available at CCL, show you which one to use for which purpose, how how to use them, and which ones to prioritize for repair. Feel free to bring in your own scope if you have one, and we'll be happy to teach you how to use it (and/or diagnose what's wrong with it...) For the microscopy experts, we'll also go over the fancy super-resolution STED microscope we've just been donated by BioCuriuous! This kind of equipment would normally start in the $200K range. A dedicated team at BioCurious spent more than a year building this one from scratch <https://sites.google.com/site/biocuriousmicroscopewiki/>, starting from the microscope engine out of a donated GA IIx DNA sequencer - a piece of machinery that probably cost well over $500K itself when it was new just a few years ago. A truly unique piece of equipment. STED microscopy <https://en.wikipedia.org/wiki/STED_microscopy> is one of the techniques used to break the diffraction limit in optical microscopy, allowing visualization of subcellular structures that were previously only accessible using electron microscopy! We are looking to build an expert user group around this new instrument, so come join us and help us get it up and running to do some awesome science with it! Patrik

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 is huge. It will be cleared out soon and I hope we can deal with the bicycles too, and then we can start looking at other large items like the embroidery machine and juki sewing machine table, and get those out of here. If anyone knows whose bicycle frame and wheels these are, or whose whole bicycles these are being stored here, please ask them to take them somewhere else when they're not visiting sudoroom. what do people think of that? -jake

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 technologies. Using movement, games and physics we’ll reintegrate the analytical and intuitive mind and discover new methods to liberate our mind, body and spirit through knowledge, knowing and finding out.

Re: [sudo-discuss] pick&place machine .csv file dissection

OK i renamed the repository to pos2charmhigh to match the true name so the new link is: https://github.com/sudoroom/pos2charmhigh/ Miloh was doing some work on the machine earlier tonight, but he's into using GEDA not KiCAD, but i'm sure his contributions will lift all boats. you can push to: git@github.com:sudoroom/pos2charmhigh.git thank you -jake On Tue, 25 Jul 2017, Morgan Allen wrote: > there was a rational behind calling the repo pcb2... but... dunno > > Anyhow, pos2... is for the fact the KiCad outputs .pos (position) files. > > Feel free to collaborate where ever, hopefully no one forces you to sign up > for GitHub. > > As for future updates, I can push where ever is most useful. > > -------------------------------------------------------------------------------------------------------------------------------------- > 2017 Hackaday Prize Entry > Any Colored Button <https://hackaday.io/project/19880-any-colored-button> > > Step 1.
