Game Boy Advance Hiding In a Medical Device
It turns out that medical manufacturers also do hacking once in a while. [JanHenrikH] recently tweeted a photo of an ECG-Trigger-Unit that he’d opened up. Inside he found that the LCD screen was that of a Game Boy Advance (GBA) and the reason he could tell was that the screen’s original case was still there, complete with GAME BOY ADVANCE SP written on it.
In the manufacturer’s defense, this device was likely made around the year 2000 when gaming products were some of the best sources for high speed, high quality, small LCDs displays. This design document for a …read more
Cheap, Full-Duplex Software Defined Radio With The LimeSDR
A few years ago, we saw the rise of software-defined radios with the HackRF One and the extraordinarily popular RTL-SDR USB TV tuner dongle. It’s been a few years, and technology is on a never-ending upwards crawl to smaller, cheaper, and more powerful widgets. Now, some of that innovation is making it to the world of software-defined radio. The LimeSDR Mini is out, and it’s the cheapest and most capable software defined radio yet. It’s available through a Crowd Supply campaign, with units shipping around the beginning of next year.
The specs for the LimeSDR mini are quite good, even …read more
Inventing The Induction Motor
When you think of who invented the induction motor, Nikola Tesla and Galileo Ferraris should come to mind. Though that could be a case of the squeaky wheel being the one that gets the grease. Those two were the ones who fought it out just when the infrastructure for these motors was being developed. Then again, Tesla played a huge part in inventing much of the technology behind that infrastructure.
Although they claimed to have invented it independently, nothing’s ever invented in a vacuum, and there was an interesting progression of both little guys and giants that came before them; …read more
Spy Tech: Nonlinear Junction Detectors
If you ever watch a spy movie, you’ve doubtlessly seen some nameless tech character sweep a room for bugs using some kind of detector and either declare it clean or find the hidden microphone in the lamp. Of course, as a hacker, you have to start thinking about how that would work. If you had a bug that transmits all the time, that’s easy. The lamp probably shouldn’t be emitting RF energy all the time, so that’s easy to detect and a dead give away. But what if the bug were more sophisticated? Maybe it wakes up every hour and …read more
Huge Names Confirm Their Supercon Appearances
We’re excited to announce the next batch of speakers for the 2017 Hackaday Superconference.
We are especially pleased to welcome Michael Ossmann as a speaker. He presented an RF design workshop at the 2014 Superconference which was sold out, standing room only, and still turned away dozens of people before becoming a hit on the Internet. This year he takes the stage with colleague Dominic Spill as they focus on infrared communications and the uses and abuses of such.
Dr. Christal Gordon threw down an incredible talk on biologically inspired sensors last year and we suspect she will outdo herself …read more
