BLDC Fans and How to tame them without blowing up your controller pt1

FANS, "Mysteries of Fans and how to tame them". A video that started out as an idea for a 15 minute video and the deeper I dug, the more i discovered and needed to be said. I just wanted to show how to easily add 3 wire fans to your controller board, hot end, chassis, alas I failed and now its a detailed 2 part. Clarification, I'm retired so have lots of time to deep dive into rabbit holes etc. and for this I did. With over 3 weeks of extensive research, well over 150 hours of scouring datasheets, googling how to's, scanning manufactures forums, actual experiments with replicate 3D printer drive circuits and quite a few fans (And sacrificing a RP2040 to the gods for the sake of answers) and Noctua tech support responding to me I have now finished filming all the content came out way longer than originally intended (It was going to be just 15mins, ended up over 2 hours raw. Nuts and bolts of it all is BLDC Fans really are not designed to be power pwm'd , Linear variable DC yes, but within constraints you can get away with power PWM at your own risk. Do not hook up a tachometer output from a 3 wire fan to your controller until you watch both parts This video and the next will explain all and will show proof of how this scenario will abuse the input to your microcontroller, if not properly protected it can easily blow it and based on posts i have seen in the past people may have done this but thought they made a wiring mistake or shorted something out https://www.analog.com/en/resources/a... https://noctua.at/pub/media/wysiwyg/N... https://kmpic.asus.com/images/nuc/int... https://www.intel.com/content/dam/sup... https://www.digchip.com/datasheets/pa... https://www.nxp.com/docs/en/white-pap... https://media.digikey.com/pdf/Data%20... http://www.micro-bridge.com/data/Feel... https://www.winson.com.tw/uploads/ima... https://www.winson.com.tw/Product/44 http://goodsei.com/product/Data%20She... https://www.diodes.com/assets/Datashe... https://www.digikey.ca/en/product-hig...
