Photo gallery shows evolution of cheap camera copy stand creation to take overhead closeup photos of objects Each version was made mostly from items on hand, except for a few nuts and bolts and the last two versions used rods, linear bearings and stepper motor donated by the XinCheJian City project (thanks guys).
Each version “worked”, but until latest one had plenty of issues. Latest version also makes it really easy to adjust the height by pushing and up or down button connected to an Arduino Nano a XinCheJian designed H bridge motor controller and a stepper motor driving a ball screw. Plus still required a heavy counterweight, as seen in the last photo.
The biggest challenges were doing it cheap and getting rock steady mounting of the heavy camera and vibrations from nearby traffic (was highly noticeable!).
The final version is shown in the next post. Also not shown is version based on City project using belt to drive the slide – it also required counter weight. Did not refine it further as the rod mounts were too close together and not aligned accurately. Also not shown are the different attempts at lighting and rotating/tilt table to place objects.
Camera copy stand 1 – unsteady
Camera copy stand 2 – unsteady
Camera copy stand 3 – steady, but hard to adjust height
Camera copy stand 4 – small work area
