First attempt with the home built linear rail smooth motion lime lapse rig... I'm going to call it a great success
The rail is constructed from PVC. Its controlled with an Arduino Uno. For UI it has a 9 segment led display ran off a shift register that displays a 1-9 depending on the angle of a potentiometer. Limit switches are performed by a reed switch and magnets that side anywhere on the rail. For this round I just attached a GoPro as my camera. Classic altoids box and random hardware make up the camera platform. Custom software written in the Arduino language. You know, the basics.
Comment on the video if your curious about whatever, from robotics to photography, I'll respond
