- 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

- 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?)
