by W.A. Steer  PhD

I'm Andrew, formally educated in physics, but very interested in electronic circuit design, computer programming - particularly 3D graphics and signal/image-processing - and many technical subjects. I also enjoy photography, cycling and hill walking. At university I regularly acted as projectionist for the Film Society's weekly 35mm screening. For 7 years following my PhD I was employed in the Research division of a major consumer-electronics company where I worked on display-related technologies, including polymer LED flat panel displays [forseen applications include televisions, mobile phones, PDAs, laptop computers, etc.]. Partly as a result of that work, I'd been inspired to learn more about colour perception and related aspects of digital imaging. For the past three and a half years I've worked for a science and technology consultancy in Cambridge, on an extremely diverse range of projects spanning medical devices and diagnostic equipment to aircraft parts and washing machines. The variety keeps me on my toes, and I enjoy applying tricks from physics and signal-processing to solve practical problems of commercial value.

The techmind.org website is a collection of articles I've written about various projects of mine, some formal and complete, others remain work-in-progress.

Back in 1994-95, while an undergraduate, I did a lot of development work on single-image autostereograms - the clever 3D pictures, and my early images and musings forged my original web presence, at University College London. From then on the site slowly but steadily grew, with the addition of pages on electronics, computer-interfacing, and other topics. After completing my PhD - and leaving UCL - in 2001, I needed a new host for my site, and so 'techmind.org' was born. Though refreshed and slightly reordered, techmind.org retains most of the content and spirit of the earlier site.

Slightly newer additions include pages on LCD monitor technology, (applied) Colour Science and a section on my technical investigation of new digital photographic printing services.

I hope you find the information I have provided useful, and that you might be inspired by my enthusiasm.

  • to monitor the number of accesses to different pages on my site
  • to monitor bandwidth-usage across the site
  • to gauge the distribution of how people find my site
  • to draw my attention to images being unfairly deep-linked by other sites
  • occasionally, when forums bring bursts of high traffic, to trace the thread (out of curiosity)
  • occasionally, to look at search-keywords from search-engine referrals to see how relevant (or not) my page was, or whether people are seeking something I don't offer, but could.
  • rarely, for any other purpose I see fit. The process is fairly low-tech (largely WordPad), and nothing to be scared of.

Your email address will be used purely for private correspondence, and will never be intentionally used or sold for any mass-mailing purposes (I hate spam at least as much as you do!). While I would not normally deliberately make public a private correspondence, any new ideas or information you send which become assimilated into my wider thoughts could in time leak out in some un-attributed form. Although reasonable precautions are taken, I cannot guarantee the absolute security of my email archive.
