The 2025 One Hertz Challenge: Transformation of an Educational Tool into Ten Precision Timers
In an unexpected twist, a tech-savvy individual named [Ray] has managed to transform the Smart Response PE device, a device commonly used in classrooms for answering questions, into a versatile multi-timer stopwatch.
The Smart Response PE device, reminiscent in shape and size to an old-school candybar cellphone, offers a user interface via a numeric keypad and a few extra control buttons on the front panel. The Texas Instruments CC2533 microcontroller drives a simple black-and-white LCD screen, which displays the time for each activated timer.
[Ray]'s modifications have enabled the device to function as ten separate stopwatches. Pressing a number from 0 to 9 activates a corresponding timer on the Smart Response PE device. The enter key pauses screen updates, providing a temporary lap time reading, while the Home button resets the screen and all timers.
The Smart Response PE device provides a straightforward Arduino-like programming experience, according to [Ray]. He has also provided instructions for modifying the programming pins for easy access and for adding a real power switch to the device.
However, it's important to note that hacking a Smart Response PE device to create a multi-timer stopwatch is a complex task. General steps for modifying or extending embedded devices like this would involve accessing the device's firmware, reverse engineering it to understand existing timer functions and hardware controls, developing custom code, and flashing the modified firmware back to the device hardware.
Given the lack of detailed technical specs or hacking guides, a recommended approach would be to consult any manufacturer documentation or developer resources for supported extensions, consider external software solutions or hardware stopwatch/timer devices designed for multi-timing, and if modification is allowed and safe, use standard embedded device development tools compatible with the Smart Response PE hardware.
It's essential to remember that the Smart Response PE device is proprietary hardware and software designed with specific functions and likely firmware security. Therefore, any attempts at hacking should be done with caution and respect for the intellectual property rights of the device's creators.
Despite the challenges, [Ray]'s innovative hack has opened up new possibilities for the Smart Response PE device, transforming it from a classroom tool into a versatile multi-timer stopwatch. With further exploration and development, it's exciting to imagine the potential uses this device could have beyond the classroom.
