170mm wide Smaller size of Urzas_creations "Rotating Platform: Arduino meets 3D Printing | Stepper Motor 28BYJ-48 + ULN2003" https://www.thingiverse.com/thing:4094599/comments.

Added Screws to hold top on
Pot Speed Control using Robojax ecellent code "Control Speed of Stepper Motor 28BYJ-48 with potentiometer - Robojax" https://robojax.com/learn/arduino/?vid=robojax_stepper_28BYJ-48_pot_speed.

Soon as I get the schematic done I will post here.

At power on a output is turned on ( Mini 1/8 Audio Aux mount) Optional (It turns my UV light on and off) Turn Table starts and runs 15 minutes ( Changeable in the code)
after 15 minutes table stops, Output turns off to Mini 1/8 Audio Aux mount
A buzzer sounds for 60 seconds ( Changeable in the code) Then program is ended.

Optional for safety, you can wire and use a push button to activate a relay that self latches to hold power to run everything. after buzzer ends it will release the relay. this is NOT in the Code Yet.

Parts Used: This list is just a list. I get nothing from these links, Search for better deals.
