I used a Mother Earth News article to design and build a solar air heater at my house. It took me over a year, due to having too many projects at once. Plus, I over-engineered it to death. I stuck it in the window (~45 degrees outside) and in about 30 minutes it was putting out very low flow, but 105 degree air. Decided it needed a solar powered fan. Didn't buy the fan. Didn't cover the glass when summer came. Did look at melted solar air heater in mid-summer.

You might consider having a way to cover it in the hotter months, I know I wish I'd considered that.
