The mechanical slider is based on DIY Perks camera slider build, video here: https://youtu.be/GE37xI14Fyw The electronics is based on Great Scott's stepper motor and camera slider electronics build, video here: https://youtu.be/XtpOl8FpkB8 About the electronics: Note the electronics has 2 power circuits a 12V motor power supply to power the Arduino nano and the stepper driver and a 5V logical power supply. BE CAREFUL it is very easy to get the two power circuits confused and short out components. I wrote off 2 Arduino and a stepper driver doing just this. In fact I recommend ordering multiple of everything just incase πŸ˜€ You will need to do some soldering for this project. I found a cheap 40w bigbox store soldering iron was good enough. Just practice with the iron before using it on actual components. Great Scott used a rotary encoder as the control. I found even with the schmitt trigger to debounceI could not get a clean signal to the Arduino. So I replaced it with three push buttons. I had to update the Arduino sketch to work with push buttons. Both the updated electronics circuit diagram and updated Arduino sketch are below. Note details on current limiting the stepper driver and settings up the LCD can be found on the arduino sketch readme: https://github.com/andii1701/camera_slider Updated Arduino sketch on github: https://github.com/andii1701/camera_slider Updated circuit diagram to work with push buttons: https://easyeda.com/andii/MotorizedCameraSlider_copy-0b79a2839ec5450099360a282db9948a Electronics parts list (Amazon Affiliate, support welcome!πŸ˜€πŸ˜€πŸ˜€ ): - NEMA17 stepper motor: http://amzn.to/2owrLl0 - A4988 Stepper Driver: http://amzn.to/2p2Fscp - 16x2 LCD with i2c interface: http://amzn.to/2p6vpoR - 12V 1.5A power supply: http://amzn.to/2owILau - Push buttons: http://amzn.to/2owHtMG - Solderless Breadboard: http://amzn.to/2p2JoKh - Breadboard wires: http://amzn.to/2pP2Iud - Arduino nano: http://amzn.to/2ozz8r5 - Limit switches…
