[Dynotronix] composed in to share the news that he won the 2013 LayerOne badge hacking contest. In addition to the great news he included a description of his badge hack.
We got a great look at the hardware included on the badge a number of days ago. You may keep in mind that it’s outfitted with footprints for 48 LEDs around the perimeter which are driven by two ICs. taking a look at the picture above it’s difficult to miss the truth that [Dyno] didn’t populate any type of of that. He went best for the power of the XMEGA processor to evaluate as well as produce signals.
But what particularly can you finish with the signal this thing generates? turns out a rather easy circuit can make it into a transmitter. [Dyno] concedes that it’s a incredibly finicky setup, however just a few elements on a scrap of copper clad turned this into an FM transmitter. inspect out the video where you can hear the sweeping alarm-type seems pushed to an FM radio through his voltage managed oscillator circuit which has a variety of about fifteen feet.
