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.
For the record:
- Like the vast majority of websites, I do store web serverlogs, including referrer strings. These are archived indefinitely, and are used:
- 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.
techmind.org will cause ads to be fetched from Google. Google will normally then see at least your IP
- Email sent to me is likely to be archived indefinitely. 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.
Since 2004, the techmind.org site has carried Google AdSense advertisements. The revenue covers
the costs of hosting and maintaining the website. I hope you don't find these adverts obtrusive
or distracting. Occasionally I run sponsored links at my discretion; these will always be clearly
labelled, and I do not allow any advertiser to bias my editorial stance!
I put my email address at the foot of each of my web pages, and I aim to reply to most correspondence.
Unfortunately spam email is a major problem; in August 2007 spam was hitting my inbox at a rate
approaching 200 junk emails per day (that's one every 7½ minutes on average, 24/7).
The only way I can possibly cope with this is to have some very aggressive filters set up.
Regrettably, on rare occasions, legitimate mail does not get through.
If you don't get a reply, try re-sending your mail as "plain text" (NOT html), with no attached or embedded images.
