speaking of lockboxes

pursuing the idea of time-ratings for safes, I'd imagined a safe whose dial sets a time after which the safe will open. something like a microwave I suppose.

nice night-light experiences leading me to work on advancing darkroom timers' routing conceptions now. looking for prior art in the 70's chemistry lab, 80's(?) X10 home automation, 90's(?) lighting show control, and where else ? particular moments in the spread of embedded microprocessors yielding degree of modularity.
