Ermmm… If you use several pins to get the current rating, what happens if one of the pins fails or gets corroded? Won’t you risk generating heat? Think I’d prefer nice big connectors for the power and to keep the data lines safely segregated. Depends on your needs and design I suppose.

It’s like everything, practice slowly, get good form wired in, then when you write fast for exams your writing will be worse than normal, but still legible.

Practice writing slowly and with good form. Write regularly, give yourself practice pieces. At uni you will be writing FAST, so it’ll get worse if you don’t keep disciplined.

Alternatively, learn to touch type, and type any work you need to hand in. - if your handwriting is so bad, you may want to make your notes legible to yourself for revision.

Brilliant, many thanks. With all the old phones in my cupboards I’d hoped this was the answer, but it’s good to get a second opinion.

Butt your enclosure right up against the lock body, then you reduce shearing forces trying to pull it off the door. Extend the pull bar through your enclosure so you still have a manual override.

While I’m not adverse to home automation, is this something you need in your life, or just want? I like my perimeter security too be simple and tight, extra complications make the security audit much harder.

Will your insurance stand up to home made remote control unlocking?

To answer your question, place the servo in a suitably large enclosure and practically any adhesive should work, e.g. 3mM command strips or even velcro or double sided sticky. When confident that this is what you want, use a screw.

I’ve avoided the conversation entirely. Ever since the pandemic I’ve done my own hair with clippers. Made a good enough job of it, even if I’ve sometimes needed to do a small adjustment the next day.

For a simple style it’s not that difficult if you take your time.
