Hi all, I have a 12V device I'd like to test over a long period and run on a couple of programmed sample rates as below. I've found a few timers on ebay and the like that are close, but hoping to find something that can do everything. First 24hrs: Turn on and run constantly 24hrs > 3 months: Turn on and run for ~5mins once every hour. 3+ months: Turn on and run for 10mins once every 12hrs. The supply voltage is from a 10.8V Lithium battery pack. The device that will be connected can run on anywhere from 8 >20V but can have power draws of up to 5W, so the timer will need to be able to handle that. The device will also have to run without any intervention, so happy to pay a premium for good quality stuff. One left field requirement is that the PCB must be able to fit in a 1.25" I.D. Tube - Length has no restriction. If there is nothing off the shelf and someone here can build something, or recommend a place to build something, I'm happy to pay for it.
