I have an "Air Leggy" air pump leg massager that runs continually when on, that is, it pumps up some air tubes wrapped around my leg and compresses them for 27 to 99 seconds, then deflate for 3 to 11 seconds, depending on how many times I push the up or down button after I turn it on. I'm hoping to modify the existing PCB so it can compress for a certain amount of time and then deflate for 5 - 10 minutes instead of 3 to seconds. The attached is a photo of both sides of the PCB and the motor and valve with the back side of PCB photo being flipped to match the front side with the components drawn in. Does anyone have a guess as to what the DIP8 chip is?
