Hi
Mark,
As
James has already stated, the first units to become available will
be
AVS
Transmitter and AVS Receiver - S Video and Stereo Audio
(Can be used for composite + another
composite
+ stereo eg Stereo + Video and a CCTV camera with no
audio)
AVS
Video Conferencing
Composite video and mono audio in both directions.
Can be used for video conferencing, CCTV Door Entry systems or
Mono
+ Video to Kids bedroom with KiddieCam+Audio back in the other
direction.
All
units require a 300mA DC power unit either 12V regulated or 9V unregulated
(most unregulated ones are switchable between 3-12 volts) with centre pin
positive.
AV
connections to all units are via SCART and there is an internal link that
can
be configured to grab control of the TV when the unit is powered up. The
link
can either output 12V or 5V to give either 4:3 or 16:9 image on the
TV.
This
is useful if your main TV is a 16:9 and all your AV kit is set to
widescreen.
The 4:3 TV relegated to the bedroom would automatically letterbox to give
you
the correct ratio (subject to the TV being modern
enough!)
I
have the blank PCB's and have assembled a few units to get an idea of
construction time before I finalise the prices. I have also been working on
documentation for a possible kit version although it will not be suitable
for
beginners due to the fine detail on the boards.
I
should receive a batch of 20 cases this week along with a supply of spare
end
panels so that I can finish my router jig that I use to cut the holes. I
have
proved the concept of using the router to machine the holes but not quite
got
the measurements exactly right! The edges of the
finished
holes are excellent.....they are just a bit too big at the moment
:-(
The
switcher will be a little while yet. All the circuitry has been prototyped,
the next step is making a few test boards before getting professional
boards
made. The difficult part of the switcher will be the mechanical assembly.
By
design it is a modular unit and I need to devise a low cost method of
machining a suitable case and mounting the individual cards. But it will
happen. I also need to do some more work on the control methods for the
switcher. My original used a BBC B computer but I want the unit to be self
contained and controlled by a micro controller. I might call on James for a
bit of help with the software ;-)
Right....cant sit here typing all night, I'm going
to
get the soldering iron out.

I'm sure I'm not the only one who's intensely interested in
Keith's KAT5 units! :) Can we have some idea of when they will be
ready (I understand it's very soon), and which units will be ready?
Will all units, as described on Keith's website, be launched simultaneously
(including the modular switching box)?
Cheers,
M
