But then building it still requires whatever scripting tool you use. Including the bash-ified version would not for practice, as it wouldn’t be very human readable and would have to be kept in sync with the source script. It’s much cleaner and simpler to just require python for your build environment.

I don’t see why bash would be used at all here. If you want something that doesn’t need another interpreter, then just compile a binary.

Pinecil works OK for small things, but struggles on larger joints because of it’s low power and small thermal mass. Personally, I’d prefer one of the many Hakko/Weller clones for a cheap solution.

Have you tried 3D printing enclosures? There’s a bit of up front cost if you don’t have a printer already, but after that the material costs are pretty cheap. It’s really cool to be able to make a custom enclosure with all the cutouts, integrated standoffs, panel markings, etc all in a single print.

If you like mechanical pencils and want some color, look up clutch pencils. I apologize in advance for fueling your addiction.
