Macrofab Engineering Podcast

Reverse Biasing Opamps Parker Been learning Python and OpenCV OpenCV is an open source computer vision library PyImageSearch Setup PyCharm Using Requests to use and get information from the MacroFab API Built a 3D printed chassis for holding a 5MP USB camera Taking pictures of PCBs and removing lens distortion RPI3 CM PCB done Will be testing over the weekend 6 Pack of beer riding on this board! Board does power up correctly. COMPIOT board Opamp blew up :( Symbol on Schematic unlabeled for the power inputs of the opamp Stephen Still Making the three synth modules (two envelops and one filter) Waiting on the CA3146 transistor IC This is an obsolete part Stephen wants to use it for legacy reasons Making some power supplies for tube mics (the same one that we made for JOSH). Have to figure out how to make a 6.3V or 12.6V high current rail along with a 200V to 300V low current rail. Stephen is going to use transformers that I have at my shop. One drops 120VAC to 10VAC and the other raises the
