Rotation test

I made this little video to test the performance of the stepper drivers and rotary stage. The results are encouraging, except that I probably need attach the sample to the stage (it looked like it was vibrating around), and my flash ran out of batteries at the end (that’s why it gets darker). On the positive side, it was pretty easy to do- I just set the stepper to rotate at a constant speed on one direction, then put the camera into time lapse mode. I’ll try again tomorrow after recharging the flash batteries. The bit of glitchiness at the end is because the flash couldn’t recycle fast enough to fire on a few frames, so I showed the previous image twice to keep the motion constant.
