I was wondering if it is possible to make a system (like the countertop brutus 20) that is switchable from 110v to 240v depending where you are brewing? I'd like to build one last system that I can use for the next few years where I am (240v) until I retire and move (110v). Also, portability to brew like @ the LHBS. Obviously I'd need to have removable power cords but I was wondering if it'd be possible to have switch(s) to convert from one to the other, and are PIDs and SSRs switchable or strictly 110v or 240V? Would my only choice be to build two separate control boxes or a mirrored box with one side 110v, the other 240V? Any ideas would be appreciated!
