OpenRPNCalc: Custom scientific RPN calculator based on STM32
https://www.electronics-lab.com/openrpncalc-custom-scientific-rpn-calculator-based-on-stm32/
Reverse Polish Notation (RPN) is a popular method for representing mathematical expressions. In this notation, the operator symbol comes after the operands in contrast to the Polish notation, where the operators are placed preceding the operands. For example, the Polish notation for the addition of 2 and 5 is 2+5, while in reverse Polish notation, […]

Paulo has developed an Excel-based calculator that eases the design of RC snubbers in power switching applications: In power switching applications, a designer often has to contend with spurious oscillations. These are the result of parasitic capacitances and inductance on the board and behave like the step response of an RLC circuit. These transients can […]
