- GPIB
- Robby Newell shared a sweet testing setup
- Lock in amplifiers
- Raw research stuff
- Jitter analyzer
- $200 scope? Chris has a friend who claimed the DS1054Z is lower priced now.
- Rigol rolled their own ASIC, the Phoenix chipset, doesn’t have boxcar average
- This is a rolling average after the ADC, higher ENOB
- Why digital scopes look noisy
- Jeri Ellsworth in her first Amp Hour interview said she wanted to skip the country after messing up a mask ROM
- The US Navy will replace touchscreen controls
- Dave interviewed John Kenney from Keysight (linked video is part 1 of 4)
- Chris realized the parts he talked about in #453 were actually NCNR parts (non-cancellable non-returnable)
- Returning parts
- Ordering parts for long lead times
- Shootout of 10 cent micros
- It was actually the SDCC compiler for the 3 cent micro
- GigaDevice parts (link to LCSC) are STM32 replacement components.
- These are not exactly a new phenomenon, Dangerous Proto posted (a link to a site) about it nearly 2 years ago
- Zeptobars also did a die shot of one of the parts
