Samy Kamkar demonstrates a nasty little homebrew spying device called KeySweeper that can snoop on wireless keyboard traffic and send what it finds over GSM cell networks. The device is built into a USB charger so it can be hidden anywhere, and is made from an Arduino, small 2.4ghz transceiver, and Adafruit FONA. Samy’s post goes into great detail about how the device is built, and how it cracks the wireless keyboard encryption. Great job!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
