Macrofab Engineering Podcast

Podcast Notes MacroFab is moving soon. Fun times! See Figure 1 to see all the stuff we need to move. Parker has finished the first version of the Selective Solder Fixture. It uses magnets to support the PCB to prevent sagging. Files here. To calibrate the machines MacroFab is designing, Parker is working on the O.A.T.B. or Optical Alignment Test Board. It is a 16"x16" PCB panel that has markings and footprints of all sizes to calibrate computer vision systems. As a side project, Parker is gathering parts for the Fantastic Air Realtime Tester. He is going to use a Adafruit Light Tower, the Macro Duino, and possibly the IAQ-CORE air quality sensor. The IAQ-CORE runs $35 however and Parker wants to try the CCS811 which is probably cheaper if he can get his hands on one. Stephen has been continuing work on the Synth Engine he was working on the past couple weeks. The AD9833 is up and running along with a 16bit A/D and D/A. He is able to produce a saw wave that ranges from 13.75Hz to 14080Hz. It is 0.5V/octav
