This spincoater is made for making custom circuit boards. The idea is that all boards made with this process have a 3mm mounting hole in the center.

UV curable resin is applied to both sides of a copper clad board, spun off at 3000rpm after which the speed is lowered to 300rpm and the UV light on both sides will then cure the thin layer on the board.

This is only a prototype.

The spinning mechanism is a 775 motor with a rotary encoder that is controlled by one of the PWM pins of an Arduino Nano.

Not just pop ups but dangerous pop ups.
