Before hearing about the Fubarino Contest [Joseph] never considered adding an Easter Egg to one of his own projects. But after seeing so many contest entries we think this is just the kind of fun extra that needs to make its way into every design!
The subject of his entry is an oscilloscope clock which displays our URL instead of the numbers usually found on a clock face. He’s using a SparkFun board to generate the clock — a piece of hardware we saw about 18 months ago hidden inside of a vintage scope. The feature is unlocked only when displaying roman numerals in combination with a special serial command.
Replacing the numerals with the URL isn’t entirely straight-forward. Since an oscilloscope is a vector display [Joseph] actually had to build his own array of start and end coordinates for each character. Luckily he did a fantastic job of documenting this which will allow you to make it say anything you wish.
