LEPMIS PS2-SAP

 

This is a switch input compatible interface or "Switch Access Port" to allow someone to access the functions of a SONY PS2 Playstation handset with any combination of virtually any kind of switch. The heart of the unit consists of the circuit board from a genuine SONY PS2 Dualshock handset and so there are no compatibility issues with genuine SONY games.

 

All 17 switches on the DualShock handset are available as 3.5mm jack sockets. In addition, there are two 9 way “D” type connectors where you can plug in customised proportional analogue joysticks built to suit any persons physical needs, disability or requirements.

 

All of the switch inputs ports are electrically isolated from the PS2 electronics in order to increase safety, and buffered to increase reliability.

 

In addition, there is a buzzer and two light emitting diodes to give a visual and auditory indication for when the rumble motors are or would have been activated.

 

The general physical external appearance is as below, but is subject to slight design changes and improvements.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The unit will be CE marked in accordance with the requirements of the Medical Devices Directive.

 

Feedback from trials of the prototype have been very positive.

 

SWITCH controller: Works very well, with no shorting out when you press left/right or up/down simultaneously. Very nice!

 

SWITCH COMPATIBILITY: Absolutely superb. I ran your box with 9 switches, with the main switch running through two extension cords (I was trying to get the unit to ghost), and had absolute perfect response from your unit. Brilliant!

 

ADAPTERS:

Dreamcast -      Didn't work with the analogue sticks for some reason. However, can still play some games that don't need the analogue thumb stick.

Xbox -               Worked a treat! Had great fun playing "Burnout 3".

GameCube -     Again worked very nicely indeed. Great stuff.

PC-                  Good news. It works well using a Speed-Link USB interface. I've been playing one switch games using JoyToKey: http://www.oneswitch.org.uk/2/I/JoyToKey/JoyToKey.htm as well as using switches to control the mouse pointer. It's nice and easy to test your unit on a PC, thanks to the Game Controllers control panel utility that's standard with XP.

 

Overall, I'm really impressed with your work on this.

 

Many thanks to Barrie Ellis at www.OneSwitch.org.uk  for his help and critique in identifying problems and shortcomings.

 

 

In addition to the interface, you will need the switches to plug into it. You can either source these yourself if you know what it is you want, or I can offer an assessment service to determine what special switching may be most appropriate. This will depend very much on where you are of course.

 

The customised analogue joysticks need to be individually manufactured and again I can provide that service for you. Please note that you can also connect switches to the analogue ports – even driving games can be played to a limited extent with just two switches and a non spring return throttle stick.

 

Please contact me for pricing as this will depend on your individual needs.
