Welcome to this very simple adapter modification for the Service dog activating unit.

Go Back to the start of this project here only  if you have not modified your phone or peg yet if you have then go down the page.

If you would like to build the white adapter then the information is below.

OR

 Just buy a small COUPLER 3.5mm to 3.5mm jack socket female- female. UK Click here:    USA Click here. or look on Ebay in your own Country.

In the photo above you can see the little white box this will be our GSM service dog adapter unit this will allow us to add more to the unit.

(Items you will need are listed below)

(One small plastic case)        (Two 3.5mm Sockets)        (1 meter of stereo cable with Two 3.5mm jack plugs on both ends)          (Clip from a tape measure.)

Now in the photo below you only need Two 3.5mm sockets. Solder one wire to the top of the socket and do the same with the next one.

Then solder the bottom wire to the bottom two sockets see photo below.

Now drill two holes for the sockets to be placed in the box see photo below.

In the photo below is the finished adapter unit this can be used to add more items and a lot more to the GSM service dog unit.
