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
