Is there a more powerful Force in the galaxy than coffee? I don't think so. This neat little bit of engineering turns an industrial coffee maker into R2-D2, complete with sounds.
There's a lot to like about this hack; not only does it fit the shape, but the R2-D2 sounds come direct from, of all things, a greeting card. So you can rest assured that while you're happy with your brew, R2-D2 is happy to serve it to you.
