Like the labels on the crates. Saves 6 trips up the ladder looking for ...
Thx. I was going to use a label maker but too hard to see for these old eyes. Milk crates are working out well. Local guy selling them for $5 each. Bought 12, had 6, going to get 8 more. They stack well too so if you have heavy stuff you don’t access regularly they hide pretty well in a corner.
 
I was tidying up my fan mountings for my hot air solar collectors and was thinking about where the heat exits the collectors
I get a little cold air coming back through the bottom inlet when the sun goes down and there not running (thermal siphoning?)
Right now I just have little pieces of polly that will suck against the outlets but could a person put like a P-trap on the outlets to stop this thermo siphoning and not have to rely on the polly

I doubt it. The p-trap is about being filled. Your poly flapper is probably the lowest restrict solution with out a t-stat controlled flapper. Unless someone else has an elegant solution.
But since you are powering a circulation fan a damper could be wired in.

I'm trying to come up with a lightweight metal or plastic but I'm stumped for now
Your right about wiring in a damper that takes it's power from the fan wiring that would work



Repeat back at you
 
I just did a smoke test to see if there was that much cold air coming out of thre intake it's minimal at best it's more the pipe is just cold I just need to pretty up the exhaust
The Polly is working well enough it just looks a bit crude
