Do you have any update on this article and (i) the best fan to use and (ii) how to power it?
On point two I have very little knowledge so the more idiot friendly the information, the better. Options for either battery or mains powered would be much appreciated. I note you say "Almost any 12 volt power supply can be used - I use a charger from an old discarded laptop".
I have built a small, two chambered smoker and I am trying to improve the consistency of the smoke draw. I have also looked into using bathroom fans.
Cheers and great article.
