he should take this review as the raw, non sugar-coated, unadulterated truth, and fix the issues.
Actually in an apprenticeship you get that from your instructor, unfortunately you might get it unjustified or in the worst case without a constructive conclusion

. But anyway, in the normal case you are supposed to get the reason as well and learn it

I am not a fan of superlatives, but well that is Dave´s thing, making videos and explaining stuff to an invisible audience; waking them up from the last boring

So i think the critic toward the schematics is quite what should have been teached: other people are supposed to understand it (it´s the only purpose of such a document, otherwise you could lay it out in mind or copy it from the breadboard, and it also names an author), so it should be drawn with that in mind, avoiding crossings, oriented in a proper way and have readability. I don´t know if all the additional label´s visibility status was saved within the document or got lost, but i think KiCAD does so.
After that, he should send the updated hardware for another mailbag. If the hardware works well this time, I'm sure everybody will just forget about all the previous mishaps and maybe recommend it to others as a quite capable poor mans scope.
Good, constructive advice, i´d say.
The Wiha screwdriver is partially a matter of taste, their isolated driver bit system is the only one with the rating i know of, so they flesh it out in more products. Makes it a double use case item, if one assumes that mechanics wouldn´t mind buying an electric screwdriver cause they can not bang a hammer on the cap (Wiha makes those as well). But be reminded that the usual 1/4" hex bits do not fit in there (tested with a Model 283109), kind of kills it for me.
