In Pictures: MacGyver IT - 21 tools for IT heroes

On the road, under duress, or out in the boonies -- save the day with these essential IT troubleshooting and repair tools

OpenGear ACM5004-E-i industrial console server With RS-242/422/485 environmental/intrusion/smoke/vibration sensors all wrapped up in a superb and super-flexible system, the OpenGear ACM5004-G-I serial server gives me a chance to work on my gear remotely and is small enough that I can pack it in my kit. It can be a router, firewall, VPN, virtual serial port server, and a 3G router with fail-over from Ethernet, and most importantly, it’s Linux with all the flexibility Linux brings. Last year I had the RS-232-only version, but this year, because I’m doing a bunch of RS-485 (aka my solar system), I wanted the new version with serial bus capability for SCADA-type applications.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
