So i have "so far"
First aid kit with 2 million plasters, bandages and various pills and stuff.
10 light sticks
A lantern (usb rechargable)
A pouch containing a small ratchet and bits plus some tiny spanners, minus the 10mm socket of course.
Ducktape
An orange thing which contains a fold out knife, wire, a small led torch with spare batteries and precision screwdrivers.
One of those attack spray things, your not allowed pepper spray in this country so you can get these other things that are a mild irritant to folk and make them a funny colour - of course the old granny down the post office doesnt know its not a pepper spray so you can still use it on pension day.
A fan
Various we boxes containing other pills (skitter ones, hay-fever ect)
Metal box with contact lenses (3sets) and a mini shave set
A usb micro led light
Several bottles of cleaning agents, disinfectant ect...
Some stuff tabled jungle formula to attract a shag in the forest... or something like that.
About a dozen or so foil blanket / emergency blanket film stuff you know the crap you get wrapped in to keep heat in.
Lots of wipes, gloves, pair of thick socks for the cold.
Drinking bottle
Food cubes, those thick emergency rations - enough for one dinner snack.
And lots more.
There is still stuff waiting to come, water purification tabs, a small burner, bla bla bla
I also want to fit a raspberry pi to it, put in say a dozen 18650s and a charging module and a gsm module for internet access right in the case - i have a wee screen for the pi.
I have to put a pi in everything...
