Joystick Circuits
Fake Joystick circuit - The following very simple circuit can be used to make the computer to think that there is a real joystick connected to joystick port. This adapter might be useful in some special computer testing applications when you don't have real joystick available.
Joy Stick Controlled Modernized Toy Throttle - (electronic circuit)
Joystick Interfaces - analogue interfaces for joysticks for motor controllers
PC Thermometer using PC Game Joystick Port - (electronic circuit)
Soundcard Joystick Port problem solver - Typical PC soundcards (for example Sound Blaster family) has added MIDI interface to the joystick connector by using pin 12 for MIDI output and pin 15 for MIDI input. This causes sometimes problems with some joysticks and adapters which work perfectly on standard joystick port. The following conversion circuit enables standard joystick Y-cables.
The Wire Between Multiio Card & Joystick Connector - Some PC multi-IO cards have a 16 pin header in the circuit board which is wired to the joystick connector (fitter to other slot place) using flat cable. The wiring is straight one-to-one connection but, due to the different numbering scheme of the game port connector vs the 16-way header, the pin numbers don't necessarily match.
Use PC Joystick Port to measure temperature & light levels - PC joystick port can be used very easily for simple measurement of light and temperature values. All you need for light measurements is to connect a LDR resistor between +5V and potentiometer input. For temperature measurements substitute the LDR.
Using the Joystick Port as General Purpose Input - The joystick button inputs can be used as general purpose button or switch inputs, and can also be driven by logic level signals or by open collector or open drain logic outputs. If used with a signal direct from a mechanical contact (e.g. a switch, micro switch, contact, or pushbutton), remember that the joystick port does not perform hardware debouncing, so this must be provided by external hardware or provided by software.
Wire between Multiio Card & Joystick Connector - Some PC multi-IO cards have a 16 pin header in the circuit board which is wired to the joystick connector (fitter to other slot place) using flat cable. The wiring is straight one-to-one connection but, due to the different numbering scheme of the game port connector vs the 16-way header, the pin numbers don't necessarily match (pin 16 in header is ocource lef not connected because joystick connector has only 15 pins).
Adding second Joystick to PC Joystick interface - PC joystick interface was designed to support two joysticks, but unfortunately it has only one connector. The second joystick can be added when you get a special Y-cable, which has connectors for two joysticks. Those cables can be bought ready-made….(circuit)
Build your own Joysticks & Controllers - Building your own normal PC joystick is not economically wise, but if you can't find a joystick you would like to have, then you have to consider doing it yourself. The connections inside PC joystick are quite simple to do, the harder part is the mechanics. Buttons are quite easy to mount to the case you use when you select suitable buttons, but the problematic....(design)
Convert Atari-style Joystick to PC Joystick Port - Some games are easier to play with digital joystick instead of analogue type. Unfortunately PC has only analogue joystick connector, which makes it impossible to connect normal digital joystick to it. But with a little adapter circuit, it is possible to use Atari style digital joystick with IBM PC joystick interface. The circuit adapts the joystick connectors....(circuit)
