Dumb idea: DIY camera accessory box
An idle mind is an incubator for dumb ideas. My latest hack proves just that. If you happen to wield a seriously heavy piece of machinery like a Nikon D800, it's tempting to leave the photo bag with everything in it behind and head out with just a camera on a strap and a few essentials like a spare battery, an extra storage card, and other bits.
You can tuck loose items into pockets, or pack them in a pouch. That's what I did anyway, until one day I thought that it would actually be pretty nifty to have a box with all the essentials in it that I can somehow attach to the camera itself. It sounded like a dumb enough DIY project for a lazy weekend, so I went to work.
