ESP32-Cam Adjustable Camera Macro Mount

thingiverse

I brought home a low-cost ESP32-CAM board and started to play around, then it became apparent that adding an additional lens in front of the camera would make it an excellent macro unit. All well and good, but not so easy to hold stable, so I set out to create a stand. It consists of five 3D printed parts: top/bottom mount, camera mount, turn knob, and clip to hold the PCB. Additional components include plywood (80mm x 250mm), base chip board (80mm x 160mm), two rods (5mm Dia x 250mm), one threaded spindle and nut, one ESP32-CAM, Neo Pixel Ring (16LED), an old USB cable, and a 5V power bank. The assembly is pretty much self-explanatory from the photos. I modified the code from the demo camera code and added in the LED function. When running, the only wires connected are 5V, GND, and IO13 for the Neopixels. I also added a couple of extra prints: a lens shield to help centralize the lens and fix it rigidly, a cover to hold the PCB in place and provision for a switch, and a base with a slimmer design featuring a 16mm lens recess.
