Wow, the #serial checking of #microsoft #windows 95 was super simple: https://youtube.com/watch?v=cwyH59nACzQ Even without the assumption of the internet, back then you could have easily implemented some custom key based on a #serial #number baked into the #disk ... They were just super lazy, maybe a rushed product launch or something.
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.
