The "D"  pad (aka directional pad NSEW ) is now operational.

Here it is being tested in the Blender Game engine, practising my turbo jumping.

It consists of 4 tactile switches fitted into a wedge shaped holder , which slots into a holding carrier shell which then slots onto the main Joystick.

The  "Stick" part is also a cylindrical wedge shape which pivots at the bottom of the holder.

Wiring is all routed internally.

The back of the carrier shell is capped of with a 3D printed Lego compatible 2x2 addition... I am fighting my long attachment to the "Merlin" figure, as he might remain with the joystick when it exchanges hands, though my Elves will be glad to see him go..... :-(
