I have been using a Waterrower rowing machine for quite a number of years. However I wanted to record the data from the S4 monitor automatically. I could not find an application to do this that ran on a Apple Mac. So I set myself a small challenge to learn the programming language Perl to record the data in a database.

The application will record the data output from the S4 monitor at regular intervals and store the samples in a MySQL database. If a heart rate monitor is attached to the S4 it will record that data as well. At the end of a rowing session the application calculates a summary of the data.
This application is a very crude but it does what I need it to do. Here is an article (PDF) describing how I created the project. You can download the application code from here.
