It’s not often that I need a cross-over Ethernet cable any more, since more networking gear has Auto-MDX on most ports, but every now and again I do need to dig out a cross-over cable. I usually can’t find one, and need to crimp a new one together, which I promptly lose when I’m done with it. If this happens to you, or if you happen to need an ATM cross-over cable or a T1 cable, you might be interested in the Universal Network Cable. Simply roll the selector wheel to the selected cabling standard and this cable becomes what you need: straight through, rolled, cross-over, and more. Brilliant.
It’s $30 at ThinkGeek, and $23 at Fry’s online. Get ’em while they’re hot!
