These #cheap #multimeters are missing a #trick by not having a #serial #output or #sdcard #slot https://hackaday.com/2021/12/07/multimet.. Imagine being able to #record this #data over time! It wouldn't even need to be as good as a #scope - you could just #record multiple different #values and #save them somewhere to be read onto a #computer at a later date. It would be exceptionally useful for people on the go.
