A tech enthusiast, known as MrYeester, has crafted a unique PC modification that adds an intriguing twist to the traditional boot process. This modder's creation involves a coin-operated PC, where the system only boots up after a specific coin is inserted. The concept is simple yet ingenious: no coin, no boot, and the coin must be a quarter. The project replaces the conventional front-panel button with a coin acceptor and a relay, ensuring that the PC remains dormant until the correct coin is detected. This innovative approach not only adds an element of fun but also challenges the conventional methods of powering on a computer. The core of this build is an industrial coin acceptor, programmed to recognize a specific coin denomination. MrYeester demonstrates the acceptor's ability to learn and identify the correct coin through repeated insertions, effectively rejecting other objects that mimic the coin's size but fail the sensor checks. The wiring is relatively straightforward for those familiar with basic PC modding techniques, utilizing a PSU breakout or adapter to provide 12V power to the coin acceptor and relay. The relay then triggers a short 'button press' signal for the motherboard's Power SW header, completing the process. MrYeester uses a temporary cardboard housing for the coin acceptor during testing, focusing on the electronics and boot behavior. The estimated cost of this 'insert coin to play' project is around $130, which might be a significant investment for those who frequently put their systems into hibernation or disable USB devices, as the modder suggests. This innovative PC modification showcases the creativity and ingenuity of the tech community, offering a unique way to interact with computer systems.
