	Description:		Welcome back, Mike Harrison! This is Mike’s 5th appearance on The Amp Hour! 135 224 294 412 Mike’s work is working on large light installions, so there has been a bit of a lockdown slowdown. He’s spending his time developing a product that will be a dimmer for AC based LEDs Leading edge vs trailing edge dimming SI8751 Mike mostly cares about turnoff time DMX controlled dimmer The supply chain is still catching up post COVID. Chris is having trouble finding (higher) pressure sensors and crystals. Mike suggests MEMS oscillators, like the Microchip programmable oscillators SGS Thompson AKM fire WS2812 LED accelerated life testing Any instruction that involves “very carefully” means…no Satellite that fell over Daniel from Keysight alluded to a forklift giong through a 100K device “It’s Perfectly Legal for Your Chinese Manufacturer to Copy Your Products” (maybe a bit click-baity) Mike’s clients mostly don’t care about IP PIC32 Hall effect sensing chip Thresholding ADC Mike likes the ease of MPLABX Chris has beend dealing with Simplicity Studio Old PIC parts required an external UART to talk to an RS485 transceiver (no internal UART) The number of PIC variants XRays are not prevalent in Australia because of required liceneses. Both Mike and Dave have EVs Mike has a 2018 Hyundai Kona Christmas vacation commercial 35 kWh vs 64 kWh pack on a Tesla Charging standards CCS Chademo V2G (vehicle to grid) CCS is a hardware standard spec’d by a software person Qualcomm’s “GreenPhy” Kona and Kia had issues with chargers that support solar (didn’t do detection for 3 phase) Dave could start the EEVEV brand in Australia (a Sinclair C1 with 20 kWh battery?) Xiaopeng china Mike thinks self driving will happen a lot sooner than Dave does Tesla fooled by someone’s face Cameras vs lidar Mike says 5 years You wouldn’t download a car SD card location on Hyundai Gridserve Charge at home is $0.015 per mile Working from home Cave Day Mike’s Micro-rant about Lattice charging $500 for software on old CPLDs Next week we’ll talk to Brian Faith from QuickLogic Many thanks to our Patrons, for this and all the other episodes throughout 2020! We would be nothing without them. Check out Patreon.com/TheAmpHour if you’d like to join the crowd. A special thanks to our corporate sponsor Binho, who now distribute the Sensepeek PCBite. Thanks to Juan Pablo Colasso for the picture of the LEDs
