I am truly very sorry if you feel you need the leave the project, the
off list msgs account to about 10 messages only. At no time was there
any intention to de-rail or divert the project.

About 4 of the messages were about arranging hardware to be sent to
out to Keith the remaining 6 messages can be reposted to the list if
required, I will do that on my return or perhaps Kieran could repost ?

Dont leave.  The LCD/KBD is not dead, but on its own it does little.
Personaly I think that if a project (Lighting) develops to a working
device and I am sure it will, then the other devices will follow. If
we had started with the LCD it is possible that we would have run out
of steam because it has a limited use untill the other devices are
built.

The lighting device also had the advantage that it already exists in
prototype form, which means that a complex device can be produced
quickly and perhaps more importantly it can work without a PC /
control system, it also has a limited command structure which is easy
to define.

If you want there is no reason why some of the group cannot start on
the LCD/KBD while the current project is being developed. I will help
with whatever I can.

If the group as a whole does not like the change to the lighting
control system I will go with the rest, no problem and no offence
taken.

Again please dont leave the group, your input/work is needed.

John.
