Hi all,
I am wondering if anyone has any experience with SMS sending units...this would come under phone modding I believe. I have seen for sale units of which run on a 12 volt input, you tell the person selling the unit which phone no you would like the text message sent to, when you put 12 volts across the load side of the unit it then sends a text message every 6 seconds unless you remove the voltage from the load side...if you want to change the phone no (some units can send to 4 different numbers) the owner can update the new number/s remotely some how.
I am wondering if anyone knows about these, how they are made or if anyone could tell me a forum that might be able to point me in the right direction.
Thanks
