i'm so glad you're into synthesizers! when i first started hosting Hardware Hacking Tuesdays I was trying to put together some kit designs for a sudosynth, using parts we had tons of just laying around. here's a video of a prototype that plays tunes with input from an old ROM: https://www.youtube.com/watch?v=6k8FTkc_NgY this might be a version of it that hasn't been finished: https://github.com/sudoroom/oscillator-design i'll be out of town for a couple of weeks but you should come to HHT every week and maybe we can make a synth board that people can build. -jake On Thu, 2 Mar 2017, Corey Johns wrote: > hi y'all, you may have seen me around the space this past week. > > It's a cool place!

robot dead

by Jake

this afternoon apparently someone used the robot in sudoroom and while they were using it, one of the motor driver circuits burned out. tonight the other Jake and I worked on it to try to figure out where the smoke was coming out, and we couldn't figure it out but we are going to order a replacement part for another motor driver circuit that has a known bad part, and hopefully that will fix that one and we can swap it in. in the meantime the robot cannot be moved from its present position, sorry. if anyone knows what happened I would appreciate knowing more than just "someone broke the robot and didn't want to tell anyone" thank you -jake

Re: [sudo-discuss] [CCLmembers] New Project Nano-materials

by Leticia Menchaca

Hi, I am requesting your input on this idea since I have no experience working in a collective way. I want to build a Magnetron Sputtering Vacuum Deposition System to produce thin films, ultra thin films, and nanoparticles. I am interested in working at the interface of materials science and bioengineering. My particular interest is exploring nano-materials for enhanced raman spectra signaling - including bio-engineering for enhanced fluorescence-emf detection. However, other subjects also interest me, such as the toxic effects of micro and nano-materials and how these materials interact with organisms, cells and biological processes in general. Building a thin film deposition system is a challenge but can be extremely interesting. This kind of equipment is very costly and only some very lucky people have access to learning how they are built and how they operate. This is because the magnetron sputtering chambers are used in the private industry only by trained and skilled personnel. In universities and technical colleges, only experts and selected talented students get access to these machines while working on their thesis projects. In YouTube I have watched people building their own vacuum chambers, rather crude, o.k. for hobby but not likely to work for producing nano-materials with real-life applications (sorry for being so critical). I am contemplating working on building a system using your Collective model. However, I have never worked in an open group setting and I wonder if this would be a realistic expectation and if there would be any interest at all! Although I am not alone. There are five of us in my group, we are people with similar interests living and working in Berkeley with limited free time to work on our own projects, since we have day jobs at UCB. Only one of us has actually built such equipment before. The rest in our group only have used the equipment and/or has worked on experiments using nano-materials, mainly plants. I look forward to your input. Thanks, Leticia Menchaca

spot welder

by Cere Davis

Hey Sudoers, I’m lacking experience on spot welders and would like some feedback on how much power I would need to spot weld a steel clothes hanger (for example) to itself? Do you suppose this much power would work? http://www.ebay.com/itm/2016-Pulse-Sparkle-Spot-Welder-Gold-Silver-Platinum… Looking for something that is set up to have a handpiece.

DLP Projector?
