System builders tasked with the on-site and in-shop maintenance, diagnostics, and repair of PCs need help. Portable tools to the rescue! I've discovered a baker's dozen of portable tools that can help turn a painful two-hour slog into a 15-minute snap. Even better, many of these gadgets are so small and lightweight, you can carry them in your pocket.
In this TechBuilder Recipe, I’ll introduce you to 13 of my favorite system-building tools. I'll also explain how and why they can make your job easier--and make you more efficient.
Ethernet Crossover Adapter
System builders who diagnose networks or transfer data from one PC to another are familiar with the standard three-foot crossover cable. But sometimes when you’re on-site, these necessary cables are not readily available.
The solution: ThinkGeek's Ethernet Crossover adapter. For less than $6, this device converts any standard Ethernet cable into a crossover cable. Plus, it's small enough to fit on a key chain. Here's a look at this handy, pocket-sized tool:
Ethernet Loopback Jack
Speaking of networking, if you ever need to check a network cable for continuity, or locate which port on a switch corresponds with a particular wall jack, this little gadget can help: the Ethernet Loopback Jack. It's a small RJ-45 modular plug like the ones found in a wall jack, except that it actually fits on a key ring.
You simply connect one end of a network cable to a port on a network hub/switch/router, and the other end to the loopback jack. If the cable is good, you'll see the link light on the hub/switch/router light up.
You can also connect the loopback jack to a wall outlet in the same manner. This allows you to easily match up a wall jack with a switch port back in the server room. The Ethernet Loopback Jack is cheap, too, less than $6. Check out the minimalist design:
A Wireless Router for Dial-Up Users
Do you have SOHO customers that are still using dial-up, but want the ability to share wireless access in other offices or in areas not readily-equipped with phone jacks? If so, a great solution is to install Always On Wireless'WiFlyer.
The WiFlyer is about the size of a PDA and extremely portable. It's an 802.11b wireless router with a built-in 56k modem. The WiFlyer is compatible with every ISP I’ve tested, from AOL to NetZero, and even some obscure local providers. Installation is simple: Plug it in. Enter your ISP’s phone number, a user name, and password. Now you’re ready.
Also, dial-up customers can use WiFlyer to share files and printers between their computers. WiFlyer’s built-in firewall provides top-notch security. And for a few dollars more, AlwaysOnWireless offers accelerator software that speeds dial-up browsing. What's more, with a couple of configuration tweaks, you can upgrade WiFlyer for broadband access. The picture below offers proof-positive that good things come in small packages:
