Case #99: Bob Had a Problem with the Thermal ManagementCase #99: Bob Had a Problem with the Thermal Management
March 19, 2007
NASA engineer Bob Wilson devised a technological solution for a bureaucratic problem: convince building maintenance that his office was frigid in the morning. By the time anyone responded to a call, the heat was on. So he programmed a TI MSP430-F2013 microcontroller to record the temperature continuously over several days. The size of a quarter and powered by a 3V lithium cell, it records converted, filtered, RL-encoded data from its built-in temperature transducer into Flash memory, to be read back later via a USB interface. The maintenance department was convinced.
