This looks a nice little holiday project, a sub-$30, pocket espresso maker.
Unfortunately it requires mad welding skillz, which I do not have.
It includes a little alcohol stove thing for heat.
If that looks too easy, you could go all out and make one like this…
Or you could go all out and make a lever machine, a grinder, and a roaster, pretty much from scratch…
These all seem somewhat beyond my capabilities. But it’s nice to dream…
