I’ve done this a few times and you get props. It’s straightforward in principle but that doesn’t do much for the nervous sweats when you drill that first hole in a pristine wall!
The hole in the wall wasn't as bad as drilling through to the basement with the flexible auger. I made a pilot/test hole first at the baseboard to make sure I wasn't drilling into electric or cooling.
That's the smaller hole at the baseboard with a bit of weed wacker filament pushed through. The final hole was about two inches to the right.
I used to run low voltage wiring professionally, and that looks pretty great. One tip for next time: You can use clues such as that nail to help connect what you see “up top” with where you’re looking down below. The wall itself will have a “bottom plate”, a 2x4 laid flat horizontally across the floor, and it’s nailed through the floor and you’ll often see nails such as that one exactly where the wall is.
There’s no 100% hard and fast rules, but you can also look for the presence of other holes for things like electrical wire, or HVAC vents as clues too. One really important thing to remember is that 95% of the time, electrical outlets will be mounted directly to a stud. You can knock on the wall or remove the cover plate and use a small flat screwdriver to probe around and determine which side of the outlet is against the stud, and which is in an open wall space. That helps you plan where to drill down below to give you the best shot at hitting your intended location. If you remember that studs are generally 16” apart, it can help you visualize that section of the wall.
Avoid running wires close to windows, doors, or corners. Studs can do some really funky things in those spaces, and you’ll have a much harder time.
I appreciate that you have all the screw heads lined up.
This is my next weekend's project after I accidentally ordered copper clad aluminum cable the first time. Also my first house; But it's 120 years old and been molested by plenty of people before me. So I don't mind drilling holes.
I'm probably on some spectrum because literally every outlet in my house has the screws aligned. It helps that we painted before we moved in so all the covers had to come down in preparation.
I'm slowly realizing that this isn't a rental and it's okay to do permanent things like drilling holes and replacing bathroom vents.
I was going to comment that what my first house taught me that all my projects had to be up to code ...eventually... in order to sell the place. However anyone who's aligning their faceplate screws is probably dull enough to do it right the first time.
I have a relatively new house, which means wifi was ubiquitous enough that they decided to really skimp on ethernet jacks. I've already got the main level taken care of via the unfinished basement, now just trying to work up the motivation / figure out how to run a bundle of ethernet up to the attic and take care of the upper level rooms.
I used a vacuum laser level to get the top height right, then a small hand held level to make sure the vertical lines were plumb.
It helped using one of these low voltage drywall mounts - they have tiny holes in the corners to help cut out the exact dimensions required for mounting.
