Motorized and WiFi controlled turntables V 1.0 - WIP

07. Mar. 2024 V1.0:

• first release

Use at your own risk.

Credits:

• Code:
  •  https://RandomNerdTutorials.com/stepper-motor-esp8266-websocket
  • I used the link to learn about how to control the motor. I also have used parts of the original code.
• 3D Model:
  • 3D Scanner Table by Silent_Bob
  • Photo or Video Turntable - Motorized - 608 Bearing by Inhibit

These parts on the pictures are not part of the remix:

• Bracket for DC-DC Buck Converter LM2596S
• 9V battery clip 

Please understand that I can not give support for Arduino IDE. Please note the link provided.

Ongoing:

• Measuring the battery
• Better solution for plate mounting
• Captive portal after connect

Why a stepper motor and not simply an electric geared motor? 

Geared motors are noisy and the speed can only be changed by changing the voltage, which leads to a loss of power at lower voltages.

A stepper motor, on the other hand, is quiet and always has the same power, regardless of the speed.

Even if they don't look like, they can easily move several kilograms. Tested with a filament box with 4 full spools, at 800 speed and a motor voltage of 5 V.

• There is enough space to house all the electronics
• I used a Wemos D1 so I can use either a small USB power bank or a buck converter and a 9v battery.
• Please note that a 9-volt battery drains very quickly, so I am currently working on an extension for LiPo batteries
• I designed a simple Wemos D1 mount for this purpose.
• The plate does not need to be fixed, so it can be easily removed to change the battery.
• You can use a switch
• Use double-sided adhesive tape to attach the parts inside the housing.
• The turntable provides a WiFi access point and can be controlled via WebUI
  • SSID: Turntable
  • Password: turntable
  • URL: http://192.168.4.1
  • Change the values as you like
• The speed should be between 50 - 1000
• Just select the speed and press any direction button

BOM:

• 1x Wemos D1 mini
• 1x 28BYJ-48 with controller board
• 3x 608 bearing

Arduino IDE:

• Unzip the zip file
• Open the INO file with Arduino IDE and upload it to your Wemos D1
• Use “Tools/ESP 8266 LittleFS  Data Upload” to upload the files in “data” folder
• The “data” folder has to be where the INO file is saved

WIRING:

• Use 5V
• !!!! If you use the USB port as a power source, you only need to connect the boards, but without additional battery !!!!
