Speaking of notebooks, make sure you get a good one. Basically, you want a solid lab notebook--not some spiral bound piece of junk for elementary school.
This one: https://www.amazon.com/gp/product/B01LXFNR4Z is (for me) a nice size/weight/cost mix. It's nicely bound, not huge, uses grid paper, has numbered pages, and several lined pages for a table of contents.
In certain fields (not just military), these are super common (i.e. standard office supplies): https://www.amazon.com/DIY-Indispensables-Military-Notebook-7530-00-222-3521/dp/B01D225M3C
I've had good luck with Vela Notebooks, particularly their smaller computation notebook. I also have one of their larger project notebooks which I'm currently using for a study. Not being able to remove pages allows me to maintain a chronological order of my notes, and helps me when I need to find something (a formula, a specific problem with some machine, etc.) quickly.
Some notes about me: I'm still a student at a military academy, so I have to have a notebook of some sort on me pretty much all day. I use the Vela offerings because they are very durable, the paper stands up to fountain pens, and the ink on the page is a nice photocopier-blue.
Maybe this isn't exactly what you were looking for, but I think the notebook route is the way to go!
