RE: Proposal for iPaq Touchscreen systems (in place of CBUS Switches)

["Paul Gale" <groups@xxxxxxxxxxxxxxxx>]

I did think about doing this a while back as well - I guess one of the
main=
problems from an aesthetic point of view is how you mount it. I guess remo=
ving the case and screwing it to a new custom designed front panel would
be=
the way to go.

Would also need to hack the o/s to always display the app you will use.
Als=
o need a way to reset the device in case it locks up - maybe a pin hole in
=
the front panel (I guess it depends how often it's likely to lock up)

Paul.
