Welcome to my collection of computing and electrotechnology
links...Use the following index, or browse down however you like:

- The Australian Public Access Network Association
Inc., provides community-based, not-for-profit, Internet and related
services (website hosting, etc.) to networking and IT experimenters,
like-minded individuals, and non-profit organisations.APANA regions are operating in almost all state capital cities and some other regional areas to offer services which are locally-focused and low in cost. Each region is operated by a dedicated group of volunteers (this keeps costs down).
Being community-based, APANA is different to commercial Internet providers because the regions offers extra features to members alongside straight up (low cost) Internet connectivity, such as social events, low-cost training workshops, etc.
My local network is part of the APANA Sydney region, and I am a member of the APANA Sydney Regional Committee. If you have any questions specifically about APANA Sydney, please feel free to contact me.
You can visit the dial-up access server and the website hosting server for yourself to get more of an idea of what is on offer.
- The
annual Central
Coast Amateur Radio Field Day is held in February every year at Wyong
Race Course, on the NSW Central Coast. The day is hosted by the Central Coast Amateur Radio Club, and
it's the biggest field day in the southern hemisphere.If you interested in amateur radio, electronics, or computers (in any combination), the annual Central Coast Field Day is one event you shouldn't miss for super deals on all manner of new and used radio, communications, computing and electronics items!
- RCS Design (formerly RCS
Radio) est. 1933, based here in Sydney, NSW, is the oldest (and
possibly the smallest) Printed Wiring Board factory in the world
today, having made PWB's (aka PCB's) since late 1942 by it's founder
Ron Bell, after the inventor Paul Eisler (the father of it
all) produced the first P.W.B. in the beginning of 1941/42.
RCS Design has produced all the published PCB's for projects published in
Australian electronics magazines since 1961, and they're also a
commercial/industrial manufacturer of single-sided, doubled-sided and
plated-thru hole PCB's.
- Oatley Electronics are a leading
Sydney-based Australian supplier of new and used surplus electronic
components and assemblies. Specialising in unusual items (much like the
sadly departed Sheridan Electronics and Radio Despatch outlets
of long past), Oatley Electronics stock a wide range of items which would
otherwise be nigh on impossible to find in most other retail outlets.
- In a similar
vein to Oatley Electronics, Recycled
Networks specialises in new and used surplus equipment, but in this case
the focus is on networking and related IT gear.
- If you are
in the market for surplus and/or pre-loved Sun Microsystems equipment, you might like
to check out the web pages for Sun Ripened
Kernels, a small operation run by me! 8-)Please note that because of APANA's prohibition of commercial use, these web pages are hosted outside APANA.

electronics magazine, and it is primarily directed to electronics
enthusiasts (including hobbyists), trades people and professionals in
the electronics, electrical, computing, IT and related fields.

leading electronics magazine in Europe, and it provides an excellent
insight into the electronics industry and hobby there. The construction
projects are excellent are of a much higher standard than nearly all
of the projects published in Australian electronics magazines.
- Jaycar Electronics, Dick Smith Electronics and Altronics are the major retailers of
electronics to the hobbyist and professional electronics communities here in
Australia.Jaycar and DSE are both based in Sydney, NSW, while Altronics is based in Perth, WA.

visit a place where inspiration is around every corner? Well then, you will
just have to visit Meg's Place and
see for yourself! 8-)Seriously, Meg's Place is actually the home page of Megan Miller, who runs her own web design company called Webformation. Her site is so incredibly refreshing that I could not resist adding a link for it to this page!

Some Strange and Unusual Places 
- John
Walker's web and ftp site contains
a vast array of scientific resources, reference projects and other
interesting things that will appeal to anyone with an open-minded
approach to science and it's practical applications,
particularly in the fields of computing and electrotechnology.
John's approach to research and development is welcomingly unconventional,
and as a result much of his work is quite unusual, but this just makes it
all the more interesting and worthy of more than just a casual visit.
- An
interesting combination of science and computing, Terranova is a local adaption of one of John's older
project that generates an image of a different terra-formed planet
each day using a variety of public domain image manipulation tools.
- Dr Gavin
Miller's Snake Robot site
presents information, etc. about his private research project into snake
locomotion which he started in 1987. His ongoing work has resulted in the
design and contstruction of a number of robotic snakes, MPEG's of
which are available from the site.The snake robots were inspired by his work on physically-based computer animation at Alias Research, Inc. and Apple Computer, Inc..
- Welcome to the
Do NOT Try This at Home Department!
- If you
thought regular $5 peltier-effect devices were bad karma for keeping things
cool when the going gets rough, then you have to check out what happened
when massively overclocking the CPU in Melvin Tong's computer went horridly out of control after
the high-intensity water-cooling system failed!
