On my person,
* Mobile Phone, HTC Diamond with Gmail synced mail, calendar etc. Files with serial number lists, passwords and all the info that I cannot quite remember.
* 4 USB Memory Sticks, 1gb Hirens USB, 2gb Applications (browsers, AV installs/updates, Scripts, all the common stuff I use), 4gb Files and documents synced with laptop.
* Small Gerber Multitool, scissors, small penknife, screwdrivers etc.
* Keys for particular site.
My Bag
* Laptop, Considered a netbook for space saving but the laptop will run all school software without question.
* Network Cable
* Multimeter
* Network Cable tester
* Packet of AA and AAA batteries
* Mouse
* 3.5 & 2.5 HDD to USB connector
* Toolkit - Usual assortment including RJ45 crimp tool and connectors
* 3m Cable access kit
* Variable heat Soldering kit - If I know its required
All images etc are kept on the server at each site. Any replacement kit like HDD's, power adapters etc are also kept at each site. I did try and get a shared budget of a couple of hundred pound for things like cable drums, air dusters etc but they don't like sharing so I end up ordering stuff when required.
