vibes as in walking near it etc???
the dob buggy has pneumatic tyres whic would dampened any vibes i would think and yes some sort of computer controlled variable resistor can vary.
not sure in this one, birds system is on or off from memory. once the temp has stabilised, and mirror needs to quickly reach ambient and switch off the exhaust fan.
tonight is very overcast and threatening thunder. it seems to have reached a steady temp, so it will be intersting to see how long it takes mirror to catch up. no fan tonight. plan is to cut holes tomorrow and then redo experiment with exhaust fan.
