Colin Seymour's Webpages: Home Page and Introduction

These webpages include the main topics of software, electronics, photography and light rail.

Developing from an early interest in general science, I've been interested in electronics and software both from a hobby perspective and in my professional career. This site contains a range of resources such as software applications, and informative or constructional articles on electronics mostly relating to those long-standing interests.

This site was completely rebuilt in 2016 using responsive web design, and new material has been added including new software apps, and additions to many of the previously published articles. From November 2019, new pages will be adopting HTML5.

In December 2019 I updated and included tram and light rail pages from my archives going back to 1995, which includes historical information, photos from my travels, and additional material contributed by previous readers.
