Can you find anything that can actually be programmed for random intervals (like any amount of time between 30 and 90 minutes) as well as programmable to at least the second (so something could blink on and off for one second)? This is a level of programming that I haven't found in consumer devices.
I want to switch either a standard AC socket or a USB outlet on and off on a programmed cycle. But although there are many consumer-ready timers available to do this at set times of day, programmable to the minute, I want to be able to randomize the cycles and have it programmable to the second...
