G’day Bob,

Do you reckon it would be easy to build a circuit accommodating these new humidity sensors (digital and analogue options) for an engine dehumidifier that automatically switches between an aquarium pump and an incandescent heat bulb dry out the silica desicant?

Pardon me for sidestepping your question but it might be simpler to make a dehydrator with an ammo can, the aquarium pump you mention, and use a light timer for a few hours a day. The silica will work for months and can be dried in the oven fairly quickly and reused. Pics below. I have had to replace a low-time cam and lifters due to rust. When I come back from flying, I blow the moisture out of the engine with a small air-mattress pump and hook up the dehydrator. I wrapped the pump in screen wire and put it in a bag to breath; cover it with the silica gel. 500g silica packs are pretty cheap on ebay.-Kent
