I haven't either but not sure if there is a fan in it having looked at some of the videos (might be wrong) Humm just thought of someone I know who is very good at this sort of thing he is a tool maker to trade and has ALL the gear. I will have a word with him to see if he can make something for me as he keeps bees too........ I'll keep you posted....
One quick question the drinks heater how hot does it get, as it's not producing that other stuff ? that you can produce from oxalic acid ??? is it formic acid ? (sorry newbie)
