The control panel.
Used the controller MJoy16. Installed 11 buttons with the ability to highlight, 1 mini-stick, 4 encoders, 1 potentiometer and two toggle switches with protective covers. Inside, there is still room for the installation of a second controller which, according to the customer's plan, will control the backlighting of the buttons. The case material is 1.5 mm steel cut on the laser and bent by a bending machine. Width 31 cm, depth 10 cm, height with legs 6.7 cm.
