@jutleys Thank you, those are super nice.
Watching the videos now.
Some helpful tips,
Get a handle on what there is to be done, and the steps to do it first. Lay that out in the intro.
Double-side glue the device down when using it, to avoid shakey video.
Don't put hands in front of the device.
Could do with better audio and video. Talking into the mic by turning it around might be possible. Supercuts to things and getting rid of autofocus-lag by skipping over it would be nice.
There is some colour saturation error when closing up.
Also there is a glue residue thing on your bench, it annoys the type of audience you are after
