Here’s a set of holiday themed contest entries:

With a home automation system already in place, and considering the time of year, [Thom] chose to use his Christmas tree lights as the contest easter egg. When he uses his smart phone to set the fifth channel of the lighting controller to a 50% responsibility cycle it causes the string of lights to mete out the Hackaday web address as a series of dots and dashes. You can find the code here (DOC).

[Jacques] provides up a flickering LED as the host of his hidden easter egg. When you short the two leads of the LED for a little bit it forces the picture 10F200 into a different mode that then flashes our URL in Morse Code. have a look at the assembly file. His implementation was based on the reverse engineering we saw recently.

This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!
