Been
thinking about this more since posting, and yes...
You
only need the "flush on lid close", because *any* use of the loo needs the
lid
opened, add to that the fact that as much as 10-15ppm of fecal material is
thrown into the air when you flush with the lid up, (enough that it can be
detected at 2-3metres away) I'd guess you would want the have the lid down
when
flushing...
Thing
is, would you subvert the exisitng flush, or rig up an
alternative...
Ian.
Wouldn't it be easier
to
put a switch on the lid and always replace that afterwards?

Phil,
How about this for a
solution:
We have two usage methods for the loo, and generally, men
use it either standing, or sitting whilst women use it sitting, so if
you
used an IR bounceback sensor, like the ones used in the automatic
handwashers, fitted on the cistern, so that if you sit down, your back
completed the loop, you can tell if it's being sat upon..
Then,
you need to cover us guys in upright pose, and that could be done with a
microswitch on the seat. Because, of course, we *always* put the seat up
when in use, and put it down again when we are done!
Seriously
though, that combination of sensors, with some suitable smarts should do
the trick :D

OK ... I was chatting with Brougham and Ken
last night on IRC and had a thought.
We have two loos here ...
One
downstairs and one upstairs. Neither Jo nor I use the downstairs one but
Edward does however he invariably forgets to flush (or maybe the
mechanism is too stiff for him or something) so although Jo and I do
make
an effort to check each time we pass there is often stuff left in there.
(We have solved this by using that loo as a storecupboard so he now
can't
use it.)
Anyway, what I was thinking was would it be possible to
build a better flush that could perhaps be automated at the same time?
(For example maybe automatically flush when the light is turned
off?)
Now, joking about dump valves and strain guages aside I reckon
this should be possible. Using a small header tank up in the loft (you
can still get your measured flush that way) and with a goodly sized
valve
it should be possible to get the flow that you need.
Laser.com
have some 40mm valves that I'm informed are free flowing and open
rapidly
(close speed isn't important) and a 40mm diameter pipe should easily
flow
enough water to flush a loo. The only "downside" is that these valves
are
sourced in Canada so short of ordering pipework and fittings from over
there I'm not sure what is available over here that is likely to be able
to mate up.
Anyone got any ideas?
Phil
