This is a really stupid project for a very, very rainy day.
Many of the old mobile phones, like this ancient Nokia, will dial the first number stored in their directory with just 3 presses of one button so program in your best mobile phone number as name AAAA.
Making a holder for the old phone and mounting an RC servo and a bit of electronics (pic processor) it is then connected to a spare Mach output.
When the currently running GCode program finishes, it switches off the output and the old phone dials your best mobile phone to alert you that the machine has finished. The pic processor is also programmed to wait a pre-determined time then hang-up.
With this little gizmo you can be just about anywhere in the world and know exactly when your CNC machine has finished it’s job.
Seriously though, this was the prototype for a number of units, I built some years back, to alert of site problems in a remote location without phone lines. I came across it last week, whilst tidying up, and took a picture for posterity.
Tweakie.
