I have seen in Facebook that there is a new Open Source project ot design a cutting edge calculator. In their own words, here are the main features of the calculator:
New Hardware, Classic Feel: The calculator will feature state-of-the-art hardware, ensuring longevity and performance, while maintaining the tactile and visual appeal of the classic models.
Completely Open Source: All aspects of the calculator, from the circuit board schematics to the firmware and case designs, will be open source. This allows anyone to download, modify, and share their improvements, fostering a collaborative development environment.
DIY Friendly: Designed with the DIY enthusiast in mind, the calculator can be assembled at home. Detailed assembly guides and component lists will be provided, making it accessible for both beginners and experienced makers.
High-Quality 3D Printed Case: The calculator’s case will be designed for 3D printing using SLA technology and a special ABS-like resin, ensuring a professional finish and durability. The design files will be available for free, allowing anyone to print their own case or customize it to their liking.
The keys, of course, will be slanted with twin markings per key!
