Hope i've got the right thread.
I've seen a lot of forums where people make modifications to their camera flash (i.e. 550ex, 540ex) where they add a 3.5mm socket (for pocket wizards etc.)
They further make modifications to the battery compartment and instead of using AA batteries, they use a 6V SLA battery (as this saves on replacing AA batteries).
Does anybody know any one who can do this for me?
Cheers,
