Etch-a-Sketch computer is a surprisingly simple hack We’re not sure whether to call this an Etch-a-Sketch upgrade or a computer interface downgrade but either way it’s unique. [Martin Raynsford] added a familiar red frame to his computer monitor with classic white knobs that control horizontal and vertical cursor movement. There’s even the click option by pressing the [...]

SNES arcade controller [Daniel] is making a mini arcade cabinet with an SNES housed inside. He wanted to build an arcade controller for it and chose to construct something from scratch instead of destroying an original piece of hardware. We can almost feel you guys sighing with relief at that one. He sent us some [...]

Network packet sniffing with Linux Here’s a chance to learn a little bit about network security. This article walks us through some of the core concepts of network manipulation and packet sniffing using Linux tools. [Joey Bernard] discusses the uses for packages like tcpdump, p0f, and dsniff. They are capable of recording all network traffic coming through your computer’s [...]

Wireless electricity enables next generation of annoying packaging Yep, these cereal boxes light up. They’re using a new branded-technology called eCoupling that provides electricity via induction, which means the shelves have a coil with AC power running through it. The “printed coils” on the boxes allow inventory control and data exchange presumably thanks to a [...]

555 based balancing bot This post on Reddit by [superangryguy] caught our attention today. He’s put together a video explaining the basics of how to build balancing robots, focusing on a 555 timer based one. He’s got two main versions, the 555 based one and another that is based off of two transistors. He says [...]

Disguise your Acura NSX as a Ferrari F50 We know what you’re thinking. “I have this Acura NSX, but my friends just won’t think I’m cool unless I have a Ferrari F50.” You know what? You’re right. To save yourself from that kind of ridicule, you can simply carry out a ridiculous body mod to [...]

Wireless Sniffing and Jamming of Chronos and iclicker The ubiquitous presence of wireless devices combined with easy access to powerful RF development platforms makes the everyday world around us a wireless hacker’s playground. Yesterday [Travis Goodspeed] posted an article showing how goodfet.cc can be used to sniff wireless traffic and also to jam a given [...]

Keyless entry via SMS [Billy's] work got new keys which he didn’t want to carry around with him. Instead he built this system to unlock the door via text message. It is based around a Spinneret Web Server which drives a servo motor. He’s rigged up a pipe hanger to add some leverage to the [...]

Your very own cloud chamber [Kenneth] and [Jeff] spent a weekend building a cloud chamber. This is a detection device for radiation particles that are constantly bombarding the earth. It works by creating an environment of supersaturated alcohol vapor which condenses when struck by a particle travelling through the container, leaving a wispy trail behind. This was [...]

Turning music into a light show [nickinoki] Made a light show using some amplifiers and an arduino. First he created a microphone circuit based around a LM386 Audio Amplifier. After amplifying the output of the microphone a second time, he uses three bandpass filters to block all but a few desired frequencies from reaching the arduino.  By only [...]
