Mobile Phone alarm

Hi,
heres my situation, im going to be having my work van kept outside my
house soon, but its full of expensive tools etc.
I am looking into the idea of making a mobile phone alarm. so that
when a door is opened it triggers the phone to dial a preset number
and alert me. the phone will be a nokia 3310. i was planning to
connect wiring to the circuit board under the buttons.
the way i have been planning it would work is:
a remote operated alarm unit to control the on/off. not sure what
output it has yet though.
the way the phone works it will need to have one button pressed for .5
second ( the cancel button) to clear the screen. then a 1 second pause
and another button, ( the hot key) pressed and held for 3 seconds.
relays should be fine to close the circuits on the buttons i think. i
just need to get my head around the timing side of it. the circuit
could also repeat every 30 seconds or so to make sure the message is
recieved.
any help would be much appreciated
thanks

also i am sorry, but i posted this in basic electrics section by
mistake, but i cant remove it, sorry, ive only just joined.

You could control the 'phone with a PIC microcontroller via an RS232
connection to send an SMS text message

Much easier to manually type in the message, then click through the
menus up to the last "send" point. Then one prod on the button from
some suitable actuator will send the message. No need to delve into
the phone at all.

A program called gnokii (gpl/bsd?) will allow you to control the nokia 3310
with four wires.
You could sacrifice some older 3210 and solder directly on the pcb to a max232?
and then add some mobile phone charger. Because startup time might be
considerable. Maybe you can use sms - acknowledge feature? to decide when a
successful alert has been sent.

Well I think he only wants his phone to ring in case of trouble. If he
can dedicate a phone to this he may not need to activate cancel.

If he's using a serial connection, I'd go for a Siemens phone. At least
the 35 series (obsolete bulk market phone as is the 3310) use a 3.3 V
CMOS level serial interface. A MAX232 is enough to talk AT commands to
it, make it dial, send data or SMS messages. No funny software needed.

If one is handy with PICs this must be a no-brainer.

Random thought.
Other mobile, "voice dial" set to the sound of the alarm.
 
Thanks for all your replies.
i was thinking of a fairly basic circuit originally, just a basic
timer to press buttons in order. At the moment the phone needs to
have cancel pressed first, as it is just a standard mobile, and
incomming sms and phone calls may happen. when there is a missed call
for example the hot key wont work until screen is clear and also the
first button press doesnt do anything apart from illuminate the
backlight, unless of course it is the cancel button, if you follow
me.

Also i have no experiance with PICs. I understand what they do but i
dont know how to program them and i dont have the facilities to do
it.

thanks again. any further help would be great!

What about a remote door bell. I bought one recently equiv. to US$10.00 and
has 100 metre range - true, I tested it. Battery operated to boot - both
ends. Unless your front yard is bigger than that you may be in trouble - but
then again if it was bigger than that you wouldn't be working.

Cheers.
 
PS. Doors aren't the only point of entry on workvans. The rubber surrounding
the window can be removed allowing the glass to just pop out - it happened
to me once - have a look, there is a joint in the rubber. Thieves then reach
in and grab what they can and run off. A loud alarm at that point is the
better.

And keep any expensive equipment out of site by layering the storage areas.

Just some friendly advice.

Cheers.
 
Thanks again for the replies.
I had thought of the wireless doorbell option, then i realised that if
i could get it to ring my phone it would be perfect, could even be set
to ring home phone aswel.
as for the security, its a transit with no rear windows and a
bulkhead. so i figured that someone would either try to drive it away
then empty it, or open it up there and then and unload it, there is
going to be approx Ł2-4K of tools in the back so if someone realises
that i will need all the security i can get. It already has a tracker
fitted, but by the time its located it will more than likely be empty.
as this has happened a couple of times to others.
i have seen on the net, a SMS controller. basically a mobile is
connected by serial port to circuit and anything can be controlled by
TXT/SMS and it sends information/alerts/feedback to users phone. The
downside is that its SMS only, and having experienced delays of up to
2-3 days to recieve a txt when ideally it needs to be 2-3 seconds.

i have some very basic ideas for a circuit using a few 555s and 4017.
to set up a sequence like Cancel pressed 0.5s, pause 2s, number
pressed 3s, pause (to allow to dial and connect) 30s. and the repeat.

so would this work? a 555 in astable with delay of 3seconds, connected
to a 4017, with first 2 outputs connected to 555s in monostable one
with output of 0.5s and one with 3seconds. connected to relays to
close the circuits on buttons. would the output from 4017 drive the
555 directly? what sort of changes are needed?

And decent anti theft devices? A wheelclamp may attract attention but
could work. So could taking parts from under the hood.

A phone like the Siemens C/M/S35 had a built-in modem and will set up a
call for you if you send it ATDT01234567 through its serial port (which
is 3.3 v 'ttl' level). You can get one for a few quid. It will also send
an SMS through that port.

This would work as well. Also possible: make an oscillator, followed by
the 4017. Use the outputs of the 4017 to adjust the oscillator
frequency, so some outputs are fast and others are slow.
