Mystery box

My roommate found this device in his basement.  It was apparently something a former roommate had built.  He doesn't know what it does.  When I flip the switch, the green LED comes on, but turning the dials don't seem to do anything in particular, at least that I can see.




One of the IC's is labeled MC14013BCP, which Google says is a "Dual D-Type Flip-Flop". Another is labeled LM324N, "Quad Operational Amplifier". The third is a 7555CN, a "CMOS Timer, Gen-Purpose".

Anyone know what this thing does?  I have enough skill in electronics to know what the parts are, but not enough to figure out what they do together.
