Unplugged power cord alarm
I am looking for an alarm that goes off if a power cord comes unplugged and keeps going off until you plug the cord back in.
I have searched for quite a while on the internet trying to find something like this that is premade and am very surprised I could not find anything.
I have found a circuit schematic that shows exactly how to build a device that snaps onto a power cord and measures the electrical field that is emitted. you do not have to plug this device in it runs on 2 N cell batteries and it does not make any direct contact with the inside of the power cord. and it starts to beep after the power cord is unplugged for 8min. This is EXACTLY what I am looking for but the only problem is I can't read circuit schematics. just looks like hydroglyphics to me.

If somebody can help me find out where i can buy something like this my clones in the EZ Cloner will be very appreciative. allready lost a few batches cause of forgetting to plug it back in.
