I’ve written an introduction for my ECE senior design project, a fully-analog vacuum tube driven Theremin.  We designed and built it over the course of a semester, trying to incorporate the spirit of the device’s history into our design while adding some personal modern touches.  What is a Theremin, you ask?  Read on!  If you like what you see, stay tuned as I’ll be writing a lot more details about the project.  Next time I’ll talk about the circuit design in general and the methodology used for testing and development.  Later I’ll add detailed information about the circuit operation, the physical design, and guidance for anyone who wishes to construct a similar design.
