Hi,
I have a project in mind that requires the switching on & off of a domestic refrigerator. The purpose is to control the internal fridge temperature at a level suitable for brewing lager beer. The highest setting available on fridges is of course too low & would stop fermentation.
My idea is to provide an adjustable (timer controlled?) circuit that would operate a relay & allow switching "on" for say 30mins & then "off " for say
60 mins. This should allow the desired temperature of 18 to 20 Deg C to be achieved with a little trial & error.Can anyone oblige by helping me with a simple circuit preferably made from easily purchased low cost components.
Thanks Pete
