Also built it
I have also built the unit and find it very good, I had to add a PNP stage to the photo diode (rather than source a darlington photo transistor), as the photo diode I was using was not sensitive enough at distances over 1 Metre.
Well Designed, compliments to Fancon.
I have now buildt the PIC slave flash trigger described at this link:

It works great! Have not got it put in a box yet.
