Wear This RISC V, RPN Calculator Watch For Maximum Nerd Cred
The RISC V calculator watch, known as the Antcalc, represents a nostalgic yet innovative blend of technology and design. Developed using the CH32V002A4M6 microcontroller, it features a small OLED display and operates with Reverse Polish Notation through a twelve-button keypad. Its compact size of 30 mm x 55 mm houses impressive functionality, including the ability to hold ten registers with a mantissa of 21 digits and exponents up to +/-99. The watch allows users to perform a wide range of scientific calculations and can record and replay up to ten macros, ensuring it remains a powerful tool despite its diminutive size. The watch's design cleverly incorporates a solid core wire on the back to secure the watch band, showcasing thoughtful engineering. As a part of the CH32Lib SDK, which is still under development, the Antcalc watch offers a unique opportunity for tech enthusiasts to explore RISC V architecture. While it serves its primary function as a calculator, the potential for repurposing the microcontroller for other uses, such as playing MOD files, further enhances its appeal. This combination of practicality and fun illustrates the enduring charm of calculator watches for a new generation of tech-savvy users.
