This guide explains how to build a simple USB Analogue Joystick with optional accessibility switch sockets for use with PCs and Macs.
On a Windows PC the functions of this controller can be set to any mouse or keyboard function using JoyToKey. All kinds of functions can be assigned to the buttons including latching, auto-fire and profile switching. Using a Windows PC and Cronus Max adapter this can also be used on the Playstation 3, Xbox 360 and Xbox One as is or with additional controls.
If you're an absolute beginner, we strongly recommend that you follow "The Basic Soldering Guide" - by Alan Winstanley.
SAFETY: Always use DIY equipment under responsible supervision where appropriate, and disconnect power when not in use. These adaptations are at your own risk. Good luck!
Most of the basic components used here are commonly available from Electronics stores such as Maplin Electronics and Farnell. The Ultra-Stik 360 is available from Ultimarc along with the free configuration software.
The Ultramap utility which you can download freely from Ultimarc allows you to change the function of the joystick. Choose "Analog" for compatibility with JoyToKey and additional switch sockets. Choose "Mouse" if you'd like the joystick to act as a mouse pointer alone.
This is a good time to work out where UP and DOWN are on your joystick. Mark or Scribe the UP position onto the base of the joystick to help you later.
Drilling holes neatly needs time and patience at this stage:
Joystick (1x 15mm main hole and 4x 3mm mounting holes): Measure to the precise centre of the top of the box then make a pilot hole. Drill a 15mm hole in the dead centre of the top of the box (you may need a corded drill for a drill bit this size or an adapter). Next use four bits of blue-tack to position your joystick as centrally as you can. Mark four pilot holes through the underside and drill 4x 3mm holes.
USB cable exit hole (4mm): Make a pilot hole for the USB wire to fit through at the bottom rear of the box. Drill a 4mm hole. Use small files to ensure that there's enough room for the cable with the lid fitted.
Optional Switch Sockets: Make pilot holes for your 1-8 switch sockets then drill 7.5mm holes for each (if using Pro-Signal sockets). I find using a bit of blue-tack helps me line the sockets up as I want them.
Secure the joystick using 4x M3 nuts and bolts with washers. Tighten using pliers and a screw-driver ensuring that the joystick is as central as possible, with no restiction when you move it in all directions. Consider hot-glueing the nuts into position when finished.
Connect the USB cable to the Ultra-Stik PCB and then secure the cable to the case using a "P-clip" as pictured.
Up to eight on/off switches or switch sockets can be directly wired to the PCB. The five pins nearest the outer edge of the PCB from left-to-right are GND, 2, 4, 6, 7. The pins below them are 1, 3, 5, 8.
If using the Ultimarc connector, the colours are likely:
1 - BROWN
2 - RED
3 - ORANGE
4 - YELLOW
5 - GREEN
6 - BLUE
7 - PURPLE
8 - GREY
GND - BLACK
You can quickly test these using the Joystick controller utility in Windows (see Testing below).
Optionally hot-glue your wiring in place to give extra strength to the connection.
Fit some velcro on the base of the joystick and/or feet to increase the stability. I recommend Maxcess or Trabasack mount systems.
Hold the Windows key + "S", type "USB", click on "Setup USB game controllers, then double-click on 'Ultimarc Ultra-Stik Player 1'). Test your joystick and buttons are functioning correctly. Inspect your soldering if there are problems. Try reprogramming the joystick as something else, then back to "Analogue" via the Ultimarc utility if there are any USB connection faults.
