DIY DJ Turntable from old Computer Parts

Step 3 Add buttons

As an optional step we can add some buttons to the mouse.

Use the wheel and the screw housing from previous step to make a knob to control the second roller. Find the best position and glue the plastic parts together. The wheel will remain free and in contact with the roller. This is ideal for volume control.

Use 3 keys from the old keyboard to make the mouse buttons easier to pres. I used some scotch tape but the double sided adhesive strip would have done the job much better because it can be applied directly between the mouse button and the new key. The middle button was the easiest to put because the legs fitted into the plastic piece of the mouse’s button.

Important: make sure that the plastic legs of the keys press exactly on the red part of the mouse buttons.
