Dear Andrew and all,
I have read lately of some ideas of connecting
a buzzer across the contacts
of the oil pressure switch to give an audiable
warning of the light coming
on. I thought this sounds like a good idea (no
pun intended).
It had also crossed my mind, before Andrews sad news, that
maybe the same
could be done to monitor the temperature in the same
way.
A small bunch of electronics taking a signal in from the oil switch
and also
one from the temperature sender. A pot in the electronics could be
adjusted
to set the temperature warning level just above the norm. Once
adjusted it
should not need changed unless the sender or thermostat is
changed.
When the car was first started the buzzer would sound due to low
OP. Once
the engine turned over enough to make the OP switch it would
silence. This
buzzer sounding would be the "circuit test" to let
you know it's working.
As one drives along the country lanes, you need
not worry too much about
scanning the dashboard as the two most critical
things are being audiably
monitored and if there is a problem you'll hear
about it.
Now my motives.
I happen to run a small electronic
assembly plant. We currently make
catalytic converter amplifiers for Rover
(used on Minis and Discovery) along
with lots of other things.
Would
anyone be interested in such an add-on?. I don't mean to make a
profit, just
cover costs and I guess with shipping it may end up at £20 or
less. The
more people who are interested, the more profesional a job I
could
do.
Any thoughts on viability or alterations to the specification (if you
can
call the above a spec) would be gratefully received.
