Automating a DSLR (Pentax K100D) to shoot time lapses using an Arduino Nano and an N-channel mosfet

This video is the process I used to automate time lapse photography on my old Pentax K100D digital SLR. I did it using a method well documented around youtube that uses a micro controller like the Arduino nano I'm using with a mosfet to act like a electrically controllable switch.
I tested this design off camera and the wires that trigger the camera have 0 volts on them throughout operation, even while the camera is being triggered.
The time lapse at the end came out good but the nature of the milling, how the subject in the frame moves around, and the close view of the subject makes the time lapse itself a little hard to watch.
