I live in a loft and have very little storage. Plus I take my gear out a lot to do brew demos anf group brews. So I needed a way to store all those odd bits that I need in the course of a brew day, PLUS be able to work out of it, and get to everything when I'm brewing in some pretty rudimentry conditions, plus protect stuff from the elements.
I started with an under the bed storage bit, that seals up. I measured my auto siphon and made sure that it is long enough to fit. (Yes it says Revvy's brewing box on it.)
Then I got a bunch of different containers and played with the setup. When I got what I liked I used velcro to connect them to the bin. I can re configure it in any way I want, as long as I make sure the new internal bin has velcro in the center. The little dots work perfectly.
The blue one in the bottom, holding the mash paddle, refractometer, auto siphon, aeration wand and other longish stuff is simply a wall paper tray that had seen better days, so I cut it in half and slid the pieces together until I got the size I wanted and then taped them together.
The box on the left holds my scale, airlocks, a timer, and can hold a bottle of starsan. (There is also a "tasting cup" on a lanyard for group brew days like AHC's teach a friend to brew, where I know there's going to be a TON of beer to sample, and I want to limit my intake, at least while I'm brewing. So I keep my portions small)
The center section is actually two boxes that stack and lock together. In the bottom is a basic "tool" kit...a multi tool, small pliers, flashlight, pair of scissors for openning hop and yeast packets. You know all the little things that you find you wish you had in the field. Even a small first aid kit.
The box above is actually pre-measured test tubes of starsan (I usually don't take a bottle with me in the field, I just pre measure a bunch of tubes, so whether I'm making a gallon or 5 I have enough. There's also the stir bar, and some little metal clips I use to hang one of my glass lab thermometers inside the boil kettle when heating strike water.
The last box is where I stick "ingredients" and stuff in, hops, a baggie of 5-2 buffer, corn sugar, lactose, whatever else I might need.
Also looking back in the main picture, in the space above the blue tray and the box my red oxygen bottle, and hydrometer test jar fits nicely in.
And what you don't see is that on top of everything I keep a pair of silicone gloves to use to lift my boil kettle;
And a couple HBT signs for representing at various events. You can see those in the first two pictures.
When travelling I keep the box closed with a couple of bungy cords.
It's nice because it fits under my bed and in the back seat of my car.
