This is a cheap gsm autodialer.
It uses an old Nokia 3310 mobile phone, about a tenner on Ebay.
An 08M2 picaxe, and a few odds and ends.
PCB & Phone
Fitted to alarm box
Circuit
Program
NO modification to the mobile hardware required.
I used the cable from an old mobile headset. Use the wires that goto pin 2 and 4 of the jackplug, pin 1 is the tip. Until you get that working do not proceed to the pcb. by shorting 2 and 4 together the phone goes into voice command dialling,( get that working first). Nokia 3109c uses pins 3 and 4.
The phone requires setting for, Speed dialling On; select phone number to dial and assign to speed dial 2; select voice tags, add voice tag,press Start on phone, then 'P' of PCB to save tones to mobile.make sure the jackplug is inserted into the phone.
The top LED shows the unit is in standby.
When triggered externally, or the 'T' button pressed, the standby Led goes off, The relay Led comes on for a few seconds, then the unit starts dialing out. First the previously recorded voice command, then a short pause, then sends an alarm tone.
The receiving mobile rings, displaying the alarm mobile number, either answer and hear the alarm tones, or drop the call. The alarm mobile then shuts off.
