The idea was born from the knowledge that everyone of us has in the drawer at least one old GSM phone, that, for varied reasons, we do not use! The following application is realized using a PIC microcontroller connected to Ericsson T18 phones, testing the compatibility also with A1018 and T28. But it is not commercialized for reasons of difficult availability of the connectors, instead it can be a lot interesting for hobby use. Moreover at the end of the post you can view the links for having other combinations of Microcontroller and cell phones. GSM2 [ bidirectional GSM Remote Control - remote activator - receiver of SMS alarms - ] This is the picture of the ended project, the missed components are optional (Quartz Y1 and J1 connector...).The J2 connector is used in order to connect GSM2 to phone, therefore you will have to use a cable with connectors evidently adaptable to the used telephone.
