Hi guys. I'm a complete nuffie and looking for some help to build something similar - a countdown timer which can be manually pre-set with a specific time (H:MM:SS best case, otherwise need a minimum display of :SS) to countdown to 0. No alarm attachment is required, simply flash 0 a few times, then auto power off.

I am looking to set up MULTIPLE (probably 3) SEPARATE displays simultaneously counting down the timer with a separate control board (set, reset, power or up/down etc) to be control from one central location (different area to where timer displays will be set up.

These displays will be embedded into a table surface.

Can someone help me put this together?
