I shot these in a macro box (both clickable to bigger versions).

It's a Senseo cardboard box with 3 large holes cut on the top, left and right side. Covered those holes with sheer white paper (don't know the exact name, but anything will work).
The inside is lined with a large piece of heavy white paper.
Actually looking for different background paper, which is smoother, because this gives some texture in the shadows (an effect that I like on the second image, but looks kinda weird on the first...
I used 3 flashes, but you can easily get great results with 1 flash on the top on a wide settings and using 2 mirrors on the side. You can tweak left/right flash power by moving one of the mirrors further away.
The white background was exposed and only very slight post processing on this. This entire thing takes about 5 minutes to build, and once you have it set up, it takes about 3 seconds to photograph any new object...
