I was thinking it would be cool to have our composting toilet vent fan have two speeds - normal and high. Would be great if you could hit a button (or trigger it from lifting the cover) to run high for 20 mins then return to normal speed. I have not seen anything like this even though these PWM controllers get pretty fancy for computer cooling systems.
Also looking to vent through the floor but recall there are some concerns with back pressure if you don't do this correctly. Again struggling to re-find what others have done to circumvent (ahem) this problem.
One more thing; I want to make this bench toilet removable so hoping the vent system can be disconnected and thus trying to keep the vent diameter to a minimum. I wonder given the fan would be operating on two speeds and I don't mind some noise when on high I could use 1" OD PVC pipe.
