Age: 13 Inspiration: http://www.youtube.com/watch?v=d6EmGKlB7ao Purpose: An excellent prank Significance: Learning to build a project given several preexisting constraints in this case the size of the calculator case.
It's the ultimate prank. Your friend goes to pick up your calculator to do a math problem and instead of getting the answer he is met with your prerecorded words, in my case "Do it yourself loser!" The calculator not only features a button and microphone to record and rerecord any phrase you want stored in the battery compartment, but also has a handy switch to toggle between a calculator that gives the answer and a calculator that doesn't. The calculator was modified with a recording module tied to the equals button. An excellent prank that only got me in trouble a couple of times.
