^^ Actually I would rather let this thread live. The other one was too specific; I'd like to see something general.
Two things that I recently picked up that now has my g/f thinking she should get for her dad; one is a weather station- it turns out she checks the temperature more than I do now. The other is an
Energy Meter. I use it all the time to see how much power things use. For example, my LED Xmas lights only use 4 watts of power for the whole lot, but the wreath with regular mini bulbs takes 20 watts.
