Has anyone in Britain set up heaters in their hives with any sucess. I'm thinking of using heat mats of 7 or 14 watts (as sold petshops). Can anyone give me any info?
Another is "an inverter is a device or circuit which changes the polarity of a signal, for example from Logic-0 into Logic-1, or vice-versa."
Invert means 'to turn upside-down or inside-out'; 'to reverse the effect of'; or 'to rotate' - the latter meaning explains how it has come to be used in the context of DC to AC conversion.
