MG's Mr Self Destruct project takes the USB Killer to new levels, combining a $1.50 system-on-a-chip with a variety of payloads: smoke bombs, "sound grenades," and little explosives, cleverly choreographed with keystroke emulation, allowing the poisoned drive to first cause the connected computer to foreground a browser and load a web-page that plays an appropriate animation (a jack-in-the-box that plays "Pop Goes the Weasel" with the drive's explosive detonating for the climax).

This PowerJive USB Multimeter measures amps, volts and mAh on all my portable devices.
I wanted to know if my 3 year old 10,000 mAh USB powerbank was still holding anything close to 10,000 mAh. This USB multimeter does exactly what I am looking for. The meter sits in-line between your charging source and whatever device you seek to charge. Simply plugging the dongle in turns it on. The device immediately displays volts and charging amps.
To test capacity of a battery first you need to drain it completely. Reset the meter by plugging in the powered side, and then holding in the units only button for a few seconds. The mAh meter will zero out, and you can plug in whatever you want to charge up. When the device reaches 100% charge, the mAh meter will tell you approximately what your capacity is, at that charging rate.
My 3 year old 10,000 mAh powerbank, that has seen several hundred cycles, still has about 82% of its charge.

Nomblr created a fully-functional USB keyboard out of a 1950s Morse Key he inherited from his dad.
I can just about remember growing up around beautifully designed analogue devices like rotary dial phones, typewriters, and record players. I’ve always like the idea of converting these largely defunct objects into digital devices, and my Dad’s old Morse key seemed like a simple project to get started on.
It was a surprisingly involved process, requiring not just learning to program a Teensy but also some good old-fashioned woodwork. Read the rest
I'm pleased with this cheap Suaoki K12's ability to jump start smaller cars and motorcycles.
I gave my last USB battery kit away, a young lady was needing her car jumpstarted an awful lot and seemed it seemed the nice thing to do, (and I didn't need all the laptop dongles that were included.) I decided to try this low-cost 8000mah replacement, and it works.

For €49.95, you can own a "USB Killer" that "instantly and permanently disables unprotected hardware" with a 200V DC shock. The €13.95 USB KILLER TESTER
is a shield that blocks the killer from actually delivering its voltage to your machine (buy the tester, get the killer for half price). (via Schneier) Read the rest
The lack of a universal charging cable is one of my biggest gripes as an iPhone user.
I never have there right combination of chargers and connectors with me on any given trip, so this $9 dual charging cable is a real boon.
Charging is easy. iTune recognizes my iPhone when I plug it in, GoPros mount instantly. The zipper for managing the loose cable ends is a pretty good idea and saves me from headphone-like tangles. All in all, I am getting everything I want out of the cable.
Charging 2 devices at once via my MacBook Air is not the fastest thing on earth, but that may be more a function of the port and then cable. I'll try it with a high speed charging port soon!

When I was young, I had a clunky, inefficient dynamo attached to my bike that powered the headlight when I pedaled. The Siva Atom works the same way but it converts your pedaling into power to charge USB devices and the removable 1650mAh battery pack. Read the rest

Jack Zylkin created the USB Typewriter. I interviewed him about his creation, the response he's received, and why people are so interested in "the muggle magic of gears and pulleys and solenoids." Read the rest
