Just received components for heat controllers today:
Microchip PIC 18F2331
Potentiometers (how to make them waterproof?)
Logic level mosfets
Still one open item is: how the user interface should look/work? Lots of ideas but now when it is time to actually put something together... Yeah.
How about this:
How it works? Well...
Normally two rotary knobs in front controls the heat of two "channels" (gloves+jacket, boots+pants).
Two rotary knobs on top control the balance of heat on two areas: gloves/jacket and boot/pants.
Simple, eh? Ok, let me explain more: front knobs control the heat on upper and lower body.
Top knobs are just temporary. With them the heat balance can be adjusted (gloves vs jacket and boots vs pants). Once top part is removed (magnetically attached), front knobs raise/lower heat on respective body parts.
This design may change though...
