The Japanese gadget wizards at Thanko have created a USB soldering iron so you can melt lead on the go.
The USB Soldering Iron can heat up to 390 Fahrenheit if powered through one USB port; with two ports, it gets to 570 F. Wire it to a 9V battery it it will burn at nearly 930 F.
Thanko seems to have a policy of trying to convert every tool known to man to USB, from dental microscopes to electric razors to e-cigarettes. They also have a yen for plain old wacky stuff, like these cat-ear headphones.
They seem to think of everything when it comes to product design. The USB Soldering Iron comes with a handy LED light near the tip to illuminate the work area.
For $28, the iron also comes with a 40-inch USB cable (with two plugs), as well as a 30-inch cable for a 9V battery.
It's clearly not as clumsy or random as a blaster. An elegant weapon for a more civilized age.
