Tuesday [5:30p]: CNC Build Project, Public, Free. Freeside veterans, Preston and Eldon, will be leading this project to assemble and tune a smaller CNC for high-precision work, then design and build a full-size 4' x 4' CNC mill for the space as well. http://www.meetup.com/Freeside-Atlanta/events/109131302/ Tuesday [7:30p]: Open House, Public, Free. We host this meeting every Tuesday so people can check out the space, chat with members of the organization, and get together to plan projects, events, and classes. http://www.meetup.com/Freeside-Atlanta/events/109154682/ Tuesday [8:30p]: Introduction to Basic Electronics, Public, Free.

Have you been itching to donate things to Freeside, but you’re not sure what we need?  Have you been looking for volunteer opportunities to use your awesome skills?  This monthly post shall be your guide, henceforth! Items we need, in no particular order: Paint (brighter colors especially, not black/grey/white): we are painting an internet meme explosion mural in the front bathroom, and Carrie needs more paint. Paint (dark, black, matte): for shrouding the stage in the darkness. Printer ink for the HP L7680 4+ port NIC card for rack system, or full system: we are trying to build a router to create subnets, see Alan or any IT staff person for details. Mounts for rack systems: stacking the pizza boxen on top of each other just won’t do. Lumber and other build-out materials: ask about specifics, but the two main projects that could use some lumber are for the electronics lab benches and for improvements to member storage. Small to Medium plastic bins: We can start subdividing or r

I've been busy working on this project since I last wrote about it. I have a new PCB designed and built up and another that has since been designed but not yet built. Designing electronics is a process. The first design I had built had an analog mux on it that I was using to push all the current sense signaling to a few ADCs on the board. Later designs needed those pins on the MCU for other purposes so I added an 8 channel ADC to the design and removed the mux all together. I then found that the ADC was too fast to measure the current in a useful way because the PWM I use to adjust the current would give the ADC values that were either 0% or 100% instead of a working average. I knew this going in, but assumed I'd be able to get a reliable average in a reasonable amount of time. For whatever reason though, it took about 300 samples per channel to get an reliable average value. Multiply that by 8 channels and then assume a single byte to store the value and you can see that it co
