One of the course requirements in my Algebra 2 class was to buy an overpriced, gigantic graphing calculator. It cost around $80 and like Algebra, I never used it again after that class. Until now.

Graphing-Calculator

The people over at JACP Media made the following video to show you how to turn that dusty, old, worthless calculator into an intervalometer so you can make timelapse videos.

What you need:

  • Graphic Calculator (go ahead, dust it off and relive the horrible memories of math class all over agin)
  • an Audio Cable
  • a DSLR with a shutter release port

Press a few buttons to program it and voila! You finally can use that calculator for something useful and fun. Neither of which was the original intended purpose.

Can’t find your old calculator? Check out these intervalometers for around $100 at B&H.
