We're working on an assembly board for training operators on how to assemble harnesses. They wanted me to build a cheap timer that would output the time that a roll of tape spent away from its dock. In other words, time how long it took for the operator to use the tape. So i took some time and built this dock with an integrated sensor and indicator LED. I hooked er up to a make controller and set up the serial port to send out the time.
Right now I've got a serial cable running out from the controller that goes to the computer (which shows the time). Next week I'll be getting a little LCD screen that will show the time.
Here is the serial signal coming out of hyperterminal:
So, next i'll add this little gem here, when i get it, and we'll be rolling:
