My new suggestion for future video is going further into building or using test rigs like this "probe" for testing resistors in #215.
I've imagined a situation where someone builds some analog device and wants it tested for example over some large range of frequencies, with a lot different settings or in some other conditions that would require hours of manual work. A lot of lab equipment has some ways of automating them, like those GPIB ports in almost every older bench device, I've did some research on them and they have a lot of functionality. But this is just an example, I don't know if those are worth using today.
