Some additional info on each design. The design intent as it were.
CatsCats OWN the internet.
There is a >>CAT<< rating marking on most multimeters I've seen, it's an obvious choice to
make something related to both CATs and cats.
Clean your tipThis one is about wire sponge for iron tip cleaning. Sort off. Maybe.
FuseGood old subject of "reliable" Apple fuses. (For those of you who are familiar with Louis Rossmann's channel)
Get down/No waySelf explanatory. IMO
Pull UPBased upon "Bro, do you even lift?" meme. (For those of you who are in to pumping iron)
The schematic is a made up thing (though should be functional). Pull up resistor value is 10MOhms, so it just "doesn't pull up".
La_RésistanceBased on the French WW2 resistance name and the PTH resistor value bands.
Short to groundIt has more than one meaning.
ShortcutsShortcuts are bad. They can ruin your day.
SolderYet another one design based on "Bro, do you even lift?" meme. This time covering subject of soldering skills
or lack of thereof. Inspired by how people hold soldering irons in stock images (usually by the tip - not by the handle).
