Racecar LCD display |
|
|
Hi,
I have a LCD display, that is designed to display water temp, oil temp
/ pressure etc. The unit which takes input from a sensor and display
the output on the LCD screen is missing. Can anyone give me a clue on
what would be required to create a unit to do this and how easy /
difficult it would be.
Thanks in advance
Clare

What skills do you have?
Can you solder?
Name 3 of the 555s pins from memory.
Design a 2 transistor properly biased amplifier?
Design a suitable driver chip using only magic marker?
Is the LCD just a bare LCD, or does it include some driver electronics. |

Is it a commercial unit ? if so, who is the manufacturer ?

I did say design, not implement :)

Oh, I *guess* you could read it that way. ;-) ...but still, don't you
need something to write on too? :-)

Yes it's a Stack, it's quite an old one and they don't stock the unit
to drive the display anymore. Come to think of it, I guess there will
be electronics to drive the lcd screen in the dash it's self, but I
would have to open it up and take a look.
My skills are zero in terms of electrical engineering, although im
pretty sure I could use a soldering iron.

Hard to say what it needs, then - the current models seem to vary
between some with the car-specific electronics in the display and some
with a dumb display that would need a complete set of measurement
electronics. Since you think it had a separate driver box, I'd guess
at the latter : the display is probably just a generic LCD (probably
with RS232 inputs - there is a current model like that) and you may as
well start from scratch. You'd have to open it up and describe the
components in some detail to get any further.
Or keep an eye on ebay - there are a couple of Stack bits there at
the moment.

Ok.
Best case - all the driving electronics is in the dash unit, and you
just have to supply it with the right 0-5V (or whatever) voltages.
If you cannot find manuals, it's probably going to take at least
weeks to learn (several hours a day) how to make an interface unit that
will take the voltages/currents/resistances/... from your cars sensors,
and convert them to the form the unit expects.
If it's either digital, as it may well be, or wants the LCDs driven
at a more basic level, then probably months of work.
I (if I had it, and wanted to do it) as a reasonably skilled person
that's designed a couple of small microcontroller units, temperature
controllers and stuff, would expect to have an idea of what it needed after
an hour of opening it.
I would be very, very surprised if it took me less than a couple of days
to get anything working, and a week to get it fully up and running, and
installed. (couple of hours a day)
I would not be surprised if it took a month, though would possibly have
given up by then.
Lack of documentation is a truly horrible thing - you may be faced with
essentially wires going into blobs of unmarked silicon, that you can
get no documentation on.
If you start with a working system, then it's possible to reverse engineer
fairly easily.
Otherwise, it just gets horribly complex, and as a novice (or even for
someone experienced) not having documentation can lead to irreversable
mistakes.
Such as making an educated guess about something being a power line, when
in fact it's a critical data line that will blow if you try to feed power
in to it.
Without seeing the device, I won't say that it's impossible that you could
do it, but at best, you're likely to need to learn a hell of a lot more
than you do about electronics before attempting it.
Firstly, try to find documentation, if possible.
