Base Convert – The Prototype

Inspired in part by the Hex Game from The Ben Heck Show but with the simplicity of the Microsoft Calculator in programmer mode, this project aims to create a handheld/desktop calculator for converting between HEX, DEC, and BIN base numbers up to 16 bit. I find myself during times of programing always checking my number conversions with the MS calculator. I would prefer to have a physical calculator on my desk since I prefer the tactile feel over an on screen calculator.

Train Horn Synthesis with the MSP430FR2000

I needed to generate a jarring sound for a silly reason. This project started like many other projects with a trash find, a PA speaker that was just begging to be rescued and reused. Slowly this project evolved from a simple weekend or two Arduino based solution to the four week solution that I present to you below. Like many of my projects I used this particular one as a learning experience for programing and embedding a microcontroller from the MSP430 family of microcontrollers. In between the start and end of this project I also learned about sound generation using PWM and train horn chords.
