RE: KAT5 Progress Update

Excellent news Keith. I am sure you'll make many people happy. They were waiting that switcher for years.

I see that your amp has a 4 source selection (I suppose 4 stereo, or just 4 channels?) and 2 stereo zones as an output.

Probably, people would like to have more output zones, but this proves the concept and I suppose that number of zones is not a problem.

Please make switcher modular, so we can add more zones later :-).

Cheers,

Nik

Subject: [ukha_d] KAT5 Progress Update

Hi All,

Made a significant step forwards this evening.

I have an amplifier that I started to build about 3 years ago but never
quite finished.

It consists of 2 Stereo Zones with digital volume control and a 4 source
selection.

The reason it was never quite finished was that it was controlled by
HomeVision but the Amplifier and HomeVision live in different parts of the
house. The basic design of the amplifier is one of the building blocks for
the Whole House Audio part of the KAT5 switcher.

Another intended building block for the KAT5 switcher is the "SitePlayer"
embedded web server. This is a tiny self contained webserver with some
Input/Output ports that can directly drive relays, LED's etc. It also has an
RS232 port for communication with a more powerful processor.

So what is this significant step forward.......
....sitting on the workbench is the afore mentioned amplifier happily
playing music. The source selection and volume control can be made from ANY
PC, iPaq, Fuji in the house (or the world if the firewall was opened up !

Currently feeling pretty chuffed that Siteplayer is doing what I wanted and
that I can now have properly controlled music in the Bathroom and Kitchen.
Need to order some more SitePlayer modules now because my development one
has just found a permanent home :-)

I have also been able to control SitePlayer by sending information from a
different webserver and getting SitePlayer to return its full status. This
means that people can also control it from their own web based systems such
as Graham and Andy's Home Automator software.

I can go to bed happy now :-)

This could also be the time to treat myself to Wireless for the iPaq :-)
