Spin Coater

I made some progress on my spin coater lately, and I want to share with you the advancement.
Basically a spin coater is the machine used for spin coating: and Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all. The substrate is then rotated at speeds up to 10,000 rpm to spread the coating material by centrifugal force.

I'll try to share more later when I get to finish the screen and all the electronics inside.
Your feedback will be much appreciated.
