How To Use An Old Calculator As An Intervalometer (Super Easy Hack)

You can use an old Texas Instruments TI-83 or TI-84 calculator as an intervalometer using this very simple hack that was posted on Instructables. The hack is fun and easy but it has to be said that you’ll probably get a real intervalometer for less money.

What you need:

  • Texas Instruments TI-83 (eBay) or TI-84 (eBay) Graphing Calculator
  • 2.5 mm audio cable (eBay)
  • DSLR with a shutter release port – a Canon obviously :-) but it will work with other brands too

What you have to do:

  1. Turn on the calculator and press the PRGM button.
  2. Press the Right arrow 2 times to highlight the tab at the top titled “New”
  3. Press Enter and type in a name for the intervalometer program you are making
  4. Now, enter the following code:
    • : Prompt A
    • : While 1
    • : For (H,1,A,1)
    • : End
    • : Send(A)
    • : End

Next, do this:

  1. Attach one end of the cable into the port of the calculator and the other end into the cable release port of your DSLR
  2. On the calculator, open the program you made and type in the number value of the time you want between each shot
  3. Start your time-lapse shooting session

Have fun! More information and details about the hack at Instructables.
