Chris and Dave discussed the "beta" function for MOSFETs on Falstad circuit simulatorWe found some references online to "beta" (like this archive from McGill University) but it doesn't seem to be a normal characteristic? Maybe an approximation term?Dave and other EE YouTubers were mentioned in Derek's 2nd video about the light bulb experiment and energy flowing in fields (Veritasium).Dave mentioned Alpha Phoenix as doing the simulations on this, but Chris later looked up it was the Ben Watson video that Chris was referencing during the recording.Rick HartleyLumped element model, where would we be without you?Bit rotChris has been digging into Segger Ozone and SystemView, the latter first brought up on the show with Brian AmosDave bought a bunch of gear from an optometry business at auction.Bubblegum tapshoesDave heard about this STM32F3 part with a super fast timer internal...yep, still can't get it.Open Source HW/SW MicroinverterChris asks Dave if he would put something like that on his house.Paul Zawada episodeEnphase MicroinvterterZappi chargerLeigh Brady EpisodeChris will be doing a webinar this week about the things you don't know about IoT systems.
