This morning I was starting to look at our cameras in preparation for the Trek. The stake asked if we’d video it. I have this picture in my head to have a time-lapse event where the sun rises on the camp and everything going on. Turns out the Rebel doesn’t have that functionality out of the box, and I’d need to purchase a separate device to tell the camera to take the pictures. Soon after I came across a great article at Instructables. It shows you how to program a Texas Instruments graphing calculator into an Intervalometer. I found Amanda’s calculator, and programmed it. Here’s the outcome..
Now I just need to make a male 2.5m cable longer than the one that came with my TI Link Cable.
Here’s the original posting from Instructables
