<td align="justify">Welcome to my clock pages. The reader may detect a bias here towards electric or electronic clocks, and that is unlikely to change - after all, I've been involved in electronics since I was a in my 'teens, and it's an area where I can contribute the most.
|
|
|
|
<p>I don't have a vast amount to offer as yet, but new material does pop up at reasonable intervals. While I could take a whole lot of photos of the clocks I've collected so far, I fear that this would be less than enchanting - there are already countless sites on the Net where one can see clocks far more exciting than mine.
|
|
|
|
<p>As noted, the articles here are (and will probably continue to be) primarily covering aspects of electrical and electronic based mechanical clocks that are not covered elsewhere. While I have many purely mechanical clocks, there are many people who know far more about them than I do, so I'll mainly stick to the areas where my electronics background comes in handy.
|
|
|
|
<p>For those who think they might be interested in this rather fascinating hobby, the National Association of Watch and Clock Collectors (<a href="http://www.nawcc.org/" target="_blank">NAWCC</a>) is definitely the organisation to join. The Australian site is called <a href="http://www.aussieclocks.com.au/" target="_blank">Aussie Clocks</a> (NAWCC First Australian Chapter No. 72 Inc), and meets every two months.
