I’m over in Iraq and was sent some decent coffee. Problem is no grinder and finding an electrical power supply that is stable and doesn’t burn things out is problematic in my current location.
Therefore I am looking for a relatively small hand operated coffee grinder, preferably not too expensive.
Lee Valley carries the hardware to make a coffee grinder. Although it is designed to be mounted on a decorative wooden box with drawer, I see no reason that you couldn't just put it on top of a can and grind away.
