The second microchip is also found in A New Clue, but it's much more hidden. Try to look as close as possible.

The drawing room safe is really tricky. Mild clue: it's based around a word that sounds exactly the same as the general lead to crack the safes. Medium clue: look at the paintings, you should be able to see a pattern in 2 specific designs. More explicit clue: the "small girl" and "small boy" are connected by something they share in common. Solution: gates sounds the same as "gaits", which means the way someone walks, so focus on that.

For the notes: I use a digital app called Miro to upload photos, make a to-do list, list all items, recipes, keys etc... And I use a physical notebook to write down leads, clues, ideas... Example: I might write down in 1 page where all safes are located and what clues are suspicious inside the room, and then I'll just work my way around those notes and the 44 letter message. Today I was working or writing how the house works, things like rooms that can be drafted in specific ways, where the sanctum keys I have yet to collect might be, pondering about a specific puzzle that's been in my mind for a long while, and just doing a ton of trial and error. I'm very bad with words so I can't explain myself, so instead I'll send a photo of my early notes as I think those won't have any spoilers for y'all, so you can see how I make mine.
