In this project, you can config two relays to start/stop high power devices on a specific time using PIC18f4550 and PCF8583.
Here is the Proteus Simulation and CCS Project.
All setting are configurable. It has simple 3 level menu by which you can edit start time and stop time of each relay and also you can change the current time. Since PCF8583 is used and every settings is saved on PIC18f4550 memory, even when electricity run off this device can operate normally afterward.
Here is Proteus Schematic:
Here is the actual Device:
