As stated in the guide that showed how to convert the calculator to an intervalometer, I seem to have gotten some slight variances in time between shots. Apparently the accuracy of the intervals is determined by the freshness of the batteries. Unfortunately, even slight variances are pretty noticeable in time-lapse. You'll see that the video above appears slightly "choppy." I'm also convinced that having a video editor that will do 1-frame-photos will also help me smooth out my videos a lot.
I can't remember the last time I changed the batteries on this calculator, and it gets used for Calculus homework almost every day. So before I get too upset about the inaccuracies of the calculator, I think I'll put in some brand new batteries and try again.
This was a test run; from now on I'll try to to shoot time lapses that have more points of interest than clouds moving in the sky and my little brother lounging around on the trampoline.
