A coda to my @crowdsupply #Teardown talk on low power. If you were there last month, you probably remember the exercise we did where we improved the standby run time of a gadget (an electronic candle) from 15 hours to 30 days or more. Just now, while cleaning out my backpack for vacation, I found the gadget, with the same CR1220 coin cell still powering it in standby. Lit it just to make sure, and yep: 17 days later, it's still running.
