说明：  一个自用的计时器控制电路，实现上网1小时后，断开网络4小时。如果断开电源60秒，再上电，可以再上网5分钟。cpu是义隆的78P803，电路板用电池或者大的法拉电容，整机功耗50uA以下。
(A personal use of the timer control circuit, the realization of the Internet 1 hour, 4 hours disconnected from the network. If you disconnect the power 60 seconds, then power, you can access 5 minutes. cpu is the ELAN 78P803, circuit boards or battery Farah large capacitance, whole power consumption below 50uA.)
