Podcast Notes July Hardware & Electronics Engineering Meetup by MacroFab & Mouser Electronics event is live! Come grab some pizza, beer, and socializing if your in the Houston area. 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 StephenStill 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 10VAC up to 230VAC The 10VAC rectified can potentially give 12.6VDC. If not I can drop it to 6.3VDC. The 230VAC rectified can become 325VDC. Pick Of the Week (POW) 130-in-1 Electronic Playground from SparkFunWith the closure of Radio Shack where would you buy one of these intro kits? $50 Is cheaper then Radio Shack even! Rapid Fire Opinion (RFO) Fail of the Week: Museum Buttons - Hack A Day Industrial buttons are not really kid proof Wood Lichtenberg - Instructables 12kV 35mA - Neon Sign Transformer PSU Baking soda in water as the conductor for electricity Marinate wood in baking soda water mix 342,857.1428 ohms to pull the entire PSU load Qualcomm fingerprint sensor enables virtual home button - Electronics WeeklyQualcomm has developed an ultrasonic fingerprint sensor which can operate under the glass of a mobile device avoiding the need for a mechanical home button. It also detects heartbeat and blood flow. 800 µm of cover glass and up to 650 µm of aluminum Are you interested in seeing a blog series for the synth we're working on? Let us know! Special thanks to whixr over at Tymkrs for the intro and outro!
