DYI macro set-up

Is anyone interested in Macro photography? Here is a DYI project for you. Digging through my junk drawer to day I found two small flash units, don’t know why I originally bought them, but Amazon sells them for $12.50 each (Vivitar SF-3000). I also found two sets of Cowboy Studio radio triggers (MPT-04), each set has one transmitter and two receiver’s and Cowboy Studio sells then for $21.00 each set. I bought them when I first got into off camera flash. Anyway, I put the small flash units and the radio triggers together with a broken yard stick, some nuts and bolts, and a couple of left over extension plates to make a macro flash setup. The camera is a Canon 7D and a Canon 100mm macro lens.
