After getting some question about the clicker , Alan of alspix has written a short post on how to build it (check out alspix blog for the most updated instructions):

I've read a few posts on flickr where people have tried using one of these plastic clickers to count sprocket holes but it has failed. Once you know how to make one, they work really well, so I thought it would be worthwhile documenting it properly here. The key is to ensure the clicker plastic only goes through the sprocket hole by a small amount, and it seems to work best with the clicker very close to where the film comes out of the canister.

It was time to reload my matchbox pinhole for the summer, so I took the opertunity to take some snaps of the process.....
