In a world where speed thrills but safety matters, Mike Chambers, a tech enthusiast, embarked on a mission to create a DIY speed detector using the power of iRobota and Flash. Buckle up and get ready for an exhilarating ride as we delve into the making of this ingenious device.
iRobota and Flash: An Unlikely Alliance
At the heart of this project lies the iRobota Duemilanove, a microcontroller board equipped with an ATMega328 chip. This tiny powerhouse serves as the brains of the operation, orchestrating the detection and calculation of vehicle speeds. Two photo-resistors, acting as vigilant sentinels, are connected to the iRobota, each paired with a 10k pull-down resistor for added stability.
Laser Beams: The Sentinels of Speed
Two laser pointers, like dueling swordsmen, shine their beams directly onto the photo-resistors, enclosed within a dark box, creating an invisible curtain of light. As a vehicle breaks this delicate barrier, the photo-resistors sense the change in light intensity, triggering a chain of events.
iRobota: The Mastermind Behind the Scenes
The iRobota, ever vigilant, monitors the values returned from the light sensors, its keen eyes detecting any changes that indicate the laser beam has been broken. When both laser beams are severed, the iRobota springs into action, calculating the time elapsed between the tripping of each sensor. This precious piece of information is then relayed to the Adobe AIR-based client, a software program that acts as the user interface.
Adobe AIR Client: The User-Friendly Interface
The Adobe AIR client, a sleek and user-friendly application, establishes a connection with the iRobota via a USB/Serial port, utilizing TinkerProxy as a serial port proxy. This dynamic duo ensures seamless communication between the hardware and software components, allowing the client to display the calculated speed in real-time.
Open-Source Goodness: Schematics and Codes Aplenty
In the spirit of open-source collaboration, Mike Chambers has generously shared the schematics and codes for this project on his GitHub repository. Aspiring tech enthusiasts and DIY aficionados can embark on their own speed detector adventures, armed with the knowledge and resources to bring their creations to life.
Bonus: A Dash of Inspiration
As you embark on your speed detector journey, remember the words of the great Enzo Ferrari: “Speed is nothing without control.” While pushing the limits of velocity can be exhilarating, always prioritize safety and obey traffic regulations. Let this project be a testament to your ingenuity and a reminder to drive responsibly.
As you race towards the finish line of this project, remember that the true joy lies in the journey itself. Embrace the learning, the challenges, and the satisfaction of creating something remarkable with your own hands. Happy tinkering!
