Turn a Raspberry Pi Into a Super Cheap, Packet-Sniffing Power Strip
Interesting project to convert a surge protector into a packet-sniffer via Lifehacker. For more critical coverage that includes worries about the electrical safety of the design, check Hack A Day here.
When you’re finished and plug everything in, you’ll end up with a surge protector that looks completely inconspicuous, but can capture any traffic to and from the system it’s connected to. You’ll have to come back to pick up the SD card periodically, but you could fix that by adding a Wi-Fi or 3G radio to the sniffer, drive up outside, log in, download your data, and drive away (of course, broadcasting wirelessly will increase your odds of detection and make the build bigger, so there are drawbacks.)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
