Do you want to learn how to make a circuitboard design with FOSS (Free and Open Source Software) at sudoroom with me? If you are interested in working on this, please let me know when you think is a good time to do it. Otherwise I will pick a time and make an announcement, and maybe nobody will see how it's done. i started making the circuitboard for the Hack-o-mat a few weeks ago. This circuitboard will allow a microcontroller such as a beaglebone black to control the FORTY different product vending motors in our Snackshop 2: https://github.com/sudoroom/hackomat i finished entering the schematic (with a bit of exciting vim hacking) and now it's time to render it into an actual physical circuitboard layout. We will need to lay out the card-edge connectors which plug into the vending machines' original wiring harness, and place all the components (mostly triacs) on the circuitboard, keeping the dimensions below 10cm for maximum price value. The finished design will be useful for any hackerspace wanting a computerized vending machine, or for controlling ANY 42 AC electrical loads from only 7 bits of GPIO (charlieplex style). Once the board is designed, we will send off to #hackvana in China to get them made, unless Oshpark is cheaper or more desirable. When they arrive we can start using our TWO vending machines to sell hacker candy to the omni! https://sudoroom.org/wiki/Hack-o-mat -jake
