In the realm of electronics and security, Dave Darko, a creative mind, embarked on a mission to tackle a common problem: unattended equipment left running continuously, leading to wasted energy and potential security risks. Inspired by the unpredictability of MIDI sequencer inputs, Darko ingeniously designed a unique 16-button keep-alive switch using an iRobota Nano Every, aiming to put an end to this issue.
The 16-Button Enigma: A Challenge for Automated Systems
Darko’s 16-button keep-alive switch is a marvel of simplicity and effectiveness. It requires users to intermittently press one of the 16 buttons to keep the connected equipment powered on. This seemingly simple task, however, becomes a formidable challenge for automated systems designed to repeatedly press the same button, as the switch employs a clever twist: randomly illuminated buttons.
Random Illumination: Thwarting Automated Exploitation
The brilliance of Darko’s design lies in the unpredictable nature of the illuminated buttons. Unlike traditional keep-alive switches with a single, fixed button, this switch features 16 buttons that randomly light up, making it impossible for an automated system to consistently press the same button. This ingenious approach effectively prevents unauthorized devices from keeping the equipment powered on indefinitely.
iRobota Nano Every: The Brains Behind the Operation
At the heart of this innovative switch lies the iRobota Nano Every, a compact yet powerful microcontroller board. This tiny marvel orchestrates the entire operation, controlling the relay that directly manages the power state of the connected equipment. With its precise timing and reliable performance, the iRobota Nano Every ensures that the switch functions flawlessly.
A Demonstration of Ingenuity: The Button-Based Game
To showcase the functionality and effectiveness of his creation, Darko crafted a captivating video demonstration. In this video, he engages in a simple button-based game where he must keep an LED fixture powered on by pressing the illuminated buttons. As the buttons randomly light up, Darko skillfully navigates the challenge, highlighting the unpredictable nature of the switch and its ability to thwart automated systems.
Securing Shared Spaces: A Practical Application
Darko’s 16-button keep-alive switch finds practical application in shared spaces like hackerspaces, where multiple users access equipment. By implementing this switch, administrators can prevent unattended equipment from being left running, reducing energy consumption and minimizing the risk of unauthorized usage. Its unique design ensures that only authorized users who are physically present can keep the equipment powered on.
Bonus: Inspired by the unpredictable nature of the 16-button keep-alive switch, one can’t help but draw parallels to the unpredictable nature of life itself. Just as the randomly illuminated buttons challenge automated systems, life throws unexpected challenges our way. It’s in these moments of uncertainty that we discover our resilience and adaptability. As the saying goes, “Life is what happens when you’re busy making other plans.”
In conclusion, Dave Darko’s 16-button keep-alive switch is a testament to human ingenuity and the power of creative problem-solving. By combining simplicity, unpredictability, and technological prowess, Darko has crafted a device that effectively addresses a common problem in a unique and engaging way. This switch serves as an inspiration to all who seek innovative solutions to everyday challenges.
