Is the evolution of the binary clock and allows planning time ON and time OFF for a relay. To keep consumption low a bistable relay was used, ’cause it needs power only when the status changes. Through the two buttons you can set time ON, time OFF and the current time. To drive the single coil bistable relay I used an RS485 driver, because it can provide 60mA output.
