The second iteration of the (un)useless machine v1.0 focues more on the portability of
the gadgets; the density of the alloy was not taken into account in the design of the frist version. Therefore, only a few mechanisms from the previous versions are placed in the travel edition, making the design light yet compact. Selected mechanisms are:

1. 3V Incandescent Light Bulb w/ hand crank generator
2. Tea Storage w/ Burlap Cover
3. Mirror
4. A Piece of Black Walnut

The first version of the series takes the angle of a human's five common senses, the senses being smell, sight, touch, sound and time (in replace of 'taste'). The machine has two general layers. Inspired by the traditional wooden puzzle, “ 魯班鎖 ”, an old Chinese Joinery technique, the first layer is a self-holding metal lock which if assembled in a certain sequence, it requires no screws or nails to stay compactly together. Then, the second layer is composed of mechanisms that are, in general, mechanically interactive and can response to the five senses.

Lastly, the first layer, as the vessel, is interlocked with the second layer, creating a compact machine at the size of an adult's hand.
