I was contemplating making my own food dehydrator and I've got all the bits needed to make a (very) small cabinet, but I haven't got a heater. I thought one of those car 12v ceramic blower heaters might be suitable. Anyone got one they want to sell on cheap?
Also, what do I need to do to step down 240v mains current to 12Vdc, would one of those little plug-in transformers work (excuse my woeful ignorance of all things electrical).
