Default DIY project - External Power Pack

G'day all

Over the years I've become tired of the small AA batteries fading away while I'm shooting a 2-hour studio shoot, so I've made up an external power pack

It's a "rainy-day" type of DIY project .... Materials needed -
1x lo-voltage / curly cable x 1/2-metre [2ft] long
1x 13mm [1/2inch] stick of balsa wood
2x small alligator clips
2x small screws
various small tools, glue etc

1- Here's the completed setup

2- the curly cord with its alligator clips

3- the balsa wood bits cut & glued to replace the AA batteries

4- small mod to flashgun battery lid to accept cable

I use these flash guns as slave guns in the home-studio, and they often have a few minutes wait time between shots as I rearrange the subject
Now I can shoot for 6-8 hours over several sessions before the recycle time starts to increase [BTW- having a larger battery does not speed up the recycle time - that is inherent within the flashgun design]

Other things-
The curly cord comes from an old flash PC cord found in the bottom of a junk box, all cable joints are soldered.
The battery has a strap taped to it and via this strap, I hang the battery onto the studio light stand, or slide it into my trouser pocket when I'm mobile with the flash on the camera

Hope others find this helpful
