COFFEE POT CONTROL BOARD


Coffee Pot Control Board
1999
During my second summer at Electronic Design and Manufacturing (EDM), my work centered around the design of a digital control board for a Hamilton-Beach commercial coffee pot. I designed a PIC 16C57 board that sensed water level, controlled brew time, and drastically improved factory calibration procedure. I didn't have a pot to try it out in, so I built a board to simulate valve and heater loads with light bulbs. When Robert Roberts, the Presedent of EDM, and I went to Hamilton-Beach to demonstrate the design, the ecstatic Hamilton-Beach engineers got a real pot for me to plug the board into. To my relief and amazement, everything fit together and functioned perfectly! This was also the project that taught me how to use microchips.
