You can buy an electric moka which only requires some current and fresh water:



The coffee from mokas is stronger than coffee people usually drink in USA (or other countries outside EU/Latin America), since it passes through the ground coffee at higher pressure (about 1.5 atmospheres I believe). You can read more information on the wikipedia page.

They come with different sizes, the smallest one would be about 15 cm tall with a base of about 10x12 cm (at least, from the electric mokas I've seen/used). Depending on the space you have available it might be too big or small enough to pack.

The price depends a lot on the dimensions, the brand etc. but I have seen some at about €30 to €40 on Amazon/eBay and other websites.

12 hours should be arranged in a pleasing ("rotated") style around / within a rectangle. I don't ask for the hands - depending on numerical input - but only for a Graphics to begin with.
