face="Times New Roman">Having spent the last few months running a beta Metis
over my home wireless Lan, I can state the experience is truly liberating.
With my laptop I can now use my HPSDR anywhere around the house and garden,
but there are some restrictions. For example how do I rotate my antenna, how
do I tune the ATU etc., hence this project proposal.</FONT> <BR><BR><FONT
size=3 face="Times New Roman">Proposal</FONT> <BR><FONT size=3
face="Times New Roman">A standalone PCB, probably Euro card size, 100 x 160mm,
attached to an Ethernet switch in the shack. Controlled by a dsPIC33 running
Microchip’s free TCP/IP software stack providing a web server. The web content
will be stored on an SD Card, with new / modified content loaded via a web
interface, dynamic web pages can then be accessed, allowing relays to be
switched, inputs and outputs including analog variables to be monitored. While
not being able to anticipate each end users requirements, this hardware would
form the link between the internet and additional user provided
hardware.</FONT> <BR><BR><FONT size=3 face="Times New Roman">We are not
restricted to using dynamic web pages for control and monitoring, for example
a C# (QT4 etc.) skeleton application could be provided, enabling budding GUI
programmers (or hackers like myself) a starter for ten to develop shack
specific interfaces of particular importance to the individual. A volunteer
needed here .</FONT> <BR><BR><FONT size=3 face="Times New Roman">A few of
other points for consideration, I would propose the use of a free tool chain,
namely:</FONT> <BR><BR><FONT size=3 face="Times New Roman">Microchips
MPLAB IDE.</FONT> <BR><FONT size=3 face="Times New Roman">Microchips
TCP/IP stack</FONT> <BR><FONT size=3 face="Times New Roman">Microchips
C30 lite compiler</FONT> <BR><FONT size=3 face="Times New Roman">ds30
bootloader, thereby eliminating the requirement for a programmer, bootloader
preloaded on production units.</FONT> <BR><BR><FONT size=3
face="Times New Roman">There is nothing new about this proposal, hardware is
currently available from a few sources on the net, but none have the amount of
I/O I need. I’m not sure how this hardware would ‘fit’ within the HPSDR
project scope / vision, however it does open up opportunities for community
learning, provides an excuse for the HTML and PIC coders amongst us to
experiment and expand the KISS GUI programming community skills. The hardware
is not restricted to our home networks, it could easily be accessed via the
web opening up additional opportunities.</FONT> <BR><BR><FONT size=3

keeping HPSDR convention, but mainly in memory of an old dog, sadly no longer
with us, Arty.</FONT> <BR><BR><FONT size=3
