Description
GameCube Power Switch for PC Front Panel
GC2PC
This PCB is designed to allow the original GameCube power switch to function with the momentary switch required by the front panel headers on most PC motherboards. It is designed to fit exactly in place of the GameCube's original power switch PCB, minimizing the need for any physical modifications to the console's casing.
Users will need to provide their own GameCube power switch and handle the microcontroller programming, for which detailed documentation is supplied.
Features include:
- Direct compatibility with the GameCube's power switch housing.
- Attiny85 microcontroller for signal translation.
- SPI Programming interface.
- LED indicator for the 5V line.
Code
ATTiny85 Arduino Code
Arduino
const int switchPin = 3; // Pin connected to the switch (ATtiny85 pin 2, Arduino pin 3) const int ledPin = 4; // Pin connected to the LED (ATtiny85 pin 3, Arduino pin 4) int lastSwitchState; // Last stable state of the switch unsigned long lastDebounceTime = 0; // Last time the switch state was toggled unsigned long debounceDelay = 50; // Debounce delay to prevent noisy signals void setup() { pinMode(switchPin, INPUT_PULLUP); // Configure the switch pin with internal pull-up pinMode(ledPin, OUTPUT); // Configure the LED pin as an output lastSwitchState = digitalRead(switchPin); // Initialize the last known switch state } void loop() { int currentSwitchState = digitalRead(switchPin); // Read the current state of the switch // Check if the switch state has changed from the last read if (currentSwitchState != lastSwitchState && (millis() - lastDebounceTime) > debounceDelay) { lastDebounceTime = millis(); // Reset the debounce timer // Toggle the LED for 1 second if the state changes digitalWrite(ledPin, HIGH); // Turn on the LED delay(1000); // Keep it on for 1 second digitalWrite(ledPin, LOW); // Turn off the LED lastSwitchState = currentSwitchState; // Update the last switch state } }
