Why reach for a bland, commercially available calculator when you be using a model that employs RPN (Reverse Polish Notation) in its calculations and be a custom build all at the same time?

The firmware meanwhile uses the orange C key from the original calculator as a function key, alternating between standard and scientific operations. If you’re curious about RPN, we’ve taken a ...

This project contains the source code for an RPN calculator implementing a virtual machine with bytecode and supporting “Just In Time” compilation at runtime. The internal JIT compiler currently only ...

This calculator is nowhere near as stable as the TI calculator app. If you manage to input incorrect operation the RPN calculator will crash and all data stored in the RPN calculator will be lost. For ...

We propose to make a little calculator realising the four basic arithmetical operations using one Arduino and a Nextion touch display. This calculator uses the Reverse Polish Notation, which may ...
