Seven Day Black and White Challenge(3) 七日黑白照片挑戰 (三)

My theme is time. So here is my photo :

我的主題是時間，以下是我的照片:

This is my time controller of my socket. Since I have 3d-printer, I need to turn off once it finish the job. And I very like this kind of mechanical time controller instead of the electronic one since I can hear the gear sound when counting the time :)

這是我的插頭的時間控制器。因為我有一部3D打印機，所以當它完成工作時，我要把它關掉。我特別喜歡這種機械的時間控制器，因為我可以聽到它倒數時齒輪的聲音:)
