Fresh hacks every day
Would you believe you can track, and even jam law enforcement radio communications using a pretty pink pager? It turns out the digital radios using the APCO-25 protocol can be jammed using the IM-ME hardware. We've seen this 'toy' so many times... yet it keeps on surprising us. Or rather, [Travis Goodspeed's] ability to do amazing stuff with the hardware is what makes us perk up. Details about … [Read more...]
Along with hobby electronics, flying RC planes is one of [Diederich’s] favorite hobbies. When out in the field, he prefers to use an Aurora 9 radio controller, and while the remote is great, he was a bit disappointed in Hitec’s telemetry sensor lineup. He says that the sensors are pretty decent, though limited, and he was positive he could build a better telemetry solution. His sensor board … [Read more...]
[Ben Grosser] built an interactive painting robot that's pretty far removed from the LED and Arduino builds we usually see. The robot is adapted from one of the many CNC routers we've featured over the years. The control system is written in Python and uses genetic algorithms and a microphone to decide what to paint next. Robot artists have been around for decades now. When [Harold Cohen] … [Read more...]
A pair of security researchers have recently unveiled an interesting new keylogging method (PDF Research Paper) that makes use of a very unlikely smartphone component, your gyroscope. Most smart phones now come equipped with gyroscopes, which can be accessed by any application at any time. [Hao Chen and Lian Cai] were able to use an Android phone’s orientation data to pin down what buttons … [Read more...]
Instructables user [Admiral Aaron Ravensdale] just finished a high voltage plasma bulb build that makes creative use of off-the-shelf parts. As a self-described steampunk, [Adm. Ravensdale] also earned some cred by included working gears in his build. The heart of the build is a "flicker flame" candle light bulb. These light bulbs have two flame-shaped plates inside the bulb to act as … [Read more...]
Hexapod robots seem to be a dime a dozen lately, but we think you will be hard pressed to not be wowed by [Zenta’s] latest creation. He’s built a bunch of hex and octopods before, but hasn’t tried building anything quite like this. His MorpHex bot might look like your standard hexapod, but once it gets moving, you can see that it’s quite unique. Utilizing over 25 servos driven by a … [Read more...]
