More Boot Fair Stuff

Today was interesting - I got six more of the little USB temperature sensor / recorders, a Nikon SB-25 electronic flash (works but most of the switch labels etc. are all but worn away), an "impossible" gizmo for taking a photo of a smartphone screen onto their polaroid-ish film (seems to work but no film), and a copy of Randall Munroe's "Thing Explainer". Total spent £16 including admission to two sites and a cup of coffee, so I'm well pleased!
