An elderly person needs some periodic warning when the oven/burners of the electric range is on/left on, to prevent mishappenings.
In the simplest form; what would you do to emit a short (0.5 second) 'beep' or 'buzz' or 'ding' once a minute to warn the stove is on ?
Yes, 555s... Try something else, with minimalist clever components/design, perhaps activated by the AC power from the dash indicator neon warning bulbs, without the power supply transforming - rectification - regulation - timing stages.
Thought of a not very simple solution with a 1 rpm geared motor like microwave turntables use, hitting a bell every turn. A non so-mechanical option could be better.
Or... is there already an applicable gadget in the market doing that ?
