As you know the refrigerators are notorious for its energy consumption. At the peak load hours that is from 6pm to 10 pm, there will be a drop in voltage and high current drawing equipments will draw more current at that time.
Here I present a crude 8051 based circuit for overcoming that. Its very low cost and durable (I tested it my self).
- Automatic cutoff from 6pm to 10pm
- No RTC, time is kept by running on rechargeable cells.
- Dirt cheap (I mean it )
- Doubles as a kitchen clock.
