-====== A blackout detector for the Raspberry PI ======
-===== Intro =====
-This are my first steps into electronics. I have power problems at my current home,
-with random blackouts that are driving me crazy. These are specially annoying when
-you are out of home (vacation) and there is nobody there to put the big
-switch again on.
-Instead of complaing to the gods for my misfortune, I tried to workaround this
-problem in the nerd's way: I have constructed a blackout detector that sends
-me a message to my phone when the power goes off at home. So, if I am outside,
-at least I will know it.
-===== The idea =====
-I one of those fortunate guys who have an UPS at home. It is not a powerfull one,
-but at least is enough to save your data and prevent a disaster. Having this and
-a Raspberry PI, the only thing is a power detector to wire it to the GPIO bus and
-I will have my blackout detector.
-I did this by stabilizing a spare power source from an old phone and tame its output
-to 3.3V, the voltage needed by the input pins of the GPIO bus.
-==== Ladies and gentlemen, the power source ====
