Motorized camera slider

cults3d

This is a motorized camera slider powered by USB, and with a travel distance of 300mm; its small size makes it perfect for traveling, and it fits perfectly inside a backpack. For this project you will need: 2x 440mm*18mm copper pipes (they can also be of different materials); GT2 belt; M4 flat head bolts and nuts; M3 flat head bolts and nuts; 1/4 camera screw and nut; 1x Arduino Nano; 1x DRV8825 stepper motor driver (any Nema 17 driver is ok); 1x Nema 17 20mm-23mm; 1x XL6009 DCDC step-up converter; 1x USB terminal; 2x Endstop switches; 1x Potentiometer (any resistance); 1x 8mm*8mm computer button; 1x 14mm*9mm switch; 1x 11mm*6mm switch; 1x 5mm led; For the build process, follow the images; you need to drill some holes through the pipes in order to mount them to the case and use a file and sandpaper to smooth the rods; you can also add some lubricant. The belt is fixed to the camera mount using some cable ties, and the bores are fixed to the mounts using M3 bolts, nuts, and washers (they should rotate freely). The electronic circuit consists of an Arduino connected to the stepper motor driver and to all the control switches, buttons, end-stops, and led (the connection pins are listed in the Arduino program). The USB terminal powers the Arduino with 5V and the step-up converter, which converts the 5V to 12V to power the driver (you should put a 100uF 16V-25V capacitor in parallel to the driver power input). Then, you can upload the example code or write your own and the motorized camera slider is ready!
