    you can sometimes use these as a stud finder, depends on the wall

    If you ever do electronics repair and are good at soldering these are a lifesaver for quick diagnosis if the resolution is high enough. Look at the board, apply power, and the part that is shorting out will often quickly get stupid hot. Sometimes it will be a complex repair you can’t easily do like a bga chip but you’d be surprised how often it’s just a random capacitor that went bad in your phone or switch or whatever and swapping it out (or even just getting rid of it if it’s an extra filter) fixes the issue. The hard part is finding out the value bc there are never schematics

    A less easy to use alternative to this that I use bc thermal cams are expensive is squirt isopropyl alcohol or flux on the board and apply power. It’ll boil at the point where the part is shorting. Harder to determine but much cheaper. If you already have the camera though

      My go to is to upside-down spray canned air at the PCB. once the canned air boils off, it leaves a layer of frost and you can immediately tell what is hot because it melts the frost.

          This was an educational rabbit hole to go down.

          It seems not all brick houses have wall studs, but most do.

          It makes sense to me to have studs to help run utilities (electrical, air ducts, etc) and for hanging drywall.

          Studs, in the UK at least, create a gap between the brick wall and the plasterboard this is often filled with insulation and it’s where electrical cables and pipework can run.

            The insulation is usually applied on the outside of the building so the protected volume is more homogeneous, avoiding cold bridges where walls/ceilings join, cause that’s where mould tends to grow

            In newer houses yes. In older ones… Well let’s just say I’m getting tired of carving channels into solid red brick whenever I do electrics.
