The vending machine now provides some more feedback after money is put in. Source code associated with my contribution is here. I haven't documented the other components of the vending machine. https://thomaslevine.com/scm/sudo-vending Based on the implementation details, it appears to me that the bill acceptor is in fact plugged into one board (Arduino Leonardo) that is connected by serial to another board (Raspberry Pi). Why is the former board used at all? That is, why is the bill acceptor not plugged directly into the latter board?

reinstate Rannette's good standing

by Brendan Reddy-Best

I said "your 'community' space," but honestly, I still want this to be my space, too. I hardly ever make a fuss about any of this stuff because it's all so futile, you know? but in this case, I really want to make my point clear: I think we should rescind our action against Rannette. I think she's been treated unfairly. Even if she is "aggressive" towards you or your compatriots, I don't think we need white dudes policing our space of black women's bodies. Matt, you claim to have acted in another's interest and you offer an injured third party -- let them speak for themselves, because I don't think it's your place right now. If there was a violent incident that threatened our space, let's hear it from a witness or an involved party. "Something Happened" is not good enough. Otherwise "but above all the Omni Commons must maintain a safe, welcoming environment" seems to fly directly in the face of the lived experience of too many black people.

Call for Facilitators / Participants in a sudo Men's Group

by Matthew Senate

Hey all, I wanted to reach out for some feedback. Seeking folks who would want to facilitate or participate in a men's group. I've previously participated in small groups like this and found them beneficial for various reasons. I would like to see if folks have had similar or different experiences. The way I'm thinking about this would culminate in something like a regular meeting for men in the sudo room community to discuss relevant issues including those of identity, oppression, privilege, patriarchy, gender, sexuality, stereotypes, safe space, and mutual support. This may not be the best or even a viable path to approach these topics, but I wanted to throw it out there to see if there is any interest. Thanks, Matt

Re: [sudo-discuss] [CCL] Free Scanning Electron Microscope in Pleasanton! (was Fwd: [Microscopy] viaWWW:SMI3200 FIB system looking for a good home)

by Patrik D'haeseleer

Here's some images of the Seiko SMI 3200 Scanning Electron Microscope that is in need of a new home: http://www.beamservices.com/used-equipment.html http://www.caeonline.com/listing/product/9025735/seiko-smi-3200 Note that this is NOT a small system! It's not huge as SEM's go, but definitely not desktop - more like "small room sized". And it would obviously need some dedicated person to keep it in good running condition. It is however almost brand new, and currently *running*, at <5nm resolution! Beam Services Inc is down in Pleasanton, so I guess interested parties could potentially go and have a look at the system. This kind of equipment would be a significant commitment and investment in time and effort on our part, so let's coordinate on this shall we?

Re: [sudo-discuss] sudoroom 3D printer is working!

by Adam

Nope, just finding a good adhesive for reattaching it is hard. I ended up just using an open cell foam pad to push the header on the glass mechanically. Only advice is to not be too aggressive and let the glue take its time to release. Doingbot while warm would help. On Mar 21, 2018 1:34 PM, "Marc Juul" <marc(a)juul.io> wrote: Cool!

can we implement stuff-org at sudoroom?

by Jake

Henner wrote this awesome parts organizer web service, and it's running at noisebridge (and his house): https://github.com/hzeller/stuff-org here's the noisebridge implementation (type a letter to begin instant search): https://parts.noisebridge.net/# i would love to help fill it with information about the stuff we have at sudoroom, but i am not confident in my ability to install it and get it running on our network. If someone feels good about doing this, sudo make it happen and i'll help. -jake

3d printer solder paste dispensing at sudoroom using rpt2paste

by Jake

last night at sudoroom i did some things to get solder paste flowing from the TAZ 3 3d printer. i brought in a compact air compressor and adjusted its power switch to click off around 100 PSI (since it was failing to reach its design pressure in a reasonable amount of time and we only need like 40-50PSI for solder paste) i'm not sure if it's still working because it cut out apparently due to heat the last time i was running it, but possibly just because of duty cycle. It needs a fitting installed into the outlet to plumb it to the solenoid. Fittings are in the box behind the printer and there's teflon tape in the "tape" box on the shelves in sudoroom. i installed a three-port solenoid on the 3d printer which plugs in instead of the extruder resistor / temperature sensor. It contains a 47KΩ resistor to simulate a thermistor (to avoid a fault code) and it wires the nozzle heater wires to the three-port solenoid (which is rated at 24VDC matching the printer's power supply) I piped the 3-port solenoid to a syringe and mounted a syringe holder on the print head assembly in a reasonable place. A syringe of solder paste is in the sudoroom fridge and can be used. Needles of various sizes are in the cardboard box behind the 3d printer. the air compressor's outlet needs to be plumbed to the flexible black hose going to the 3-port solenoid. The solenoid needs to be mounted to the print head (a twist-tie should work). unfortunately the 3D printer's firmware seems to be cycling power to the nozzle resistor when a temperature is selected, probably because of PID parameters, so we will have to look for a set of commands (or modified firmware) to activate the solenoid properly during the dispensing process. This printer doesn't seem to have wires for a print head fan, which is how we connected the solenoid in past implementations of this setup. There will need to be a script or modification to rpt2pnp to issue the right commands for this setup. as a reminder the software for creating g-code to dispense solder paste from the .rpt file output of a KiCAD circuitboard project is here: https://github.com/hzeller/rpt2paste note that it's superseded by https://github.com/hzeller/rpt2pnp which may be newer. the latter was confirmed to (apparently) correctly process the .rpt file from the project we'll likely dispense solder paste onto first: https://github.com/fitzdoingprojects/big_battery i'll be gone for two weeks but if anyone wants to make progress on this project please write back and i'll help as much as i can. -jake

free 76-key Korg SG1 keyboard

by Jake

there is a very heavy Korg SG1 keyboard available for free in west oakland. i'm not bringing it to sudoroom but i wanted to offer it to people on this list before putting it on craigslist. I was told it works but i haven't tested it. You should be willing to take it either way. Here's an article about it from like 1987 http://www.muzines.co.uk/articles/korg-sg1-piano/258
