Australia day---weird gadget





今年的澳洲国庆日,我和hh又去赶了会集。看到了几个新鲜的玩意,跟大家汇报汇报!


这个东东叫街头音乐会(Street Concert),全自动的!没人演奏,风琴,小号,鼓,锣,各种打击乐器,自动发声。很是神奇,看看这么多小朋友在这里看呆了,我也是非常的好奇。


让我们,转到后台去看看,其中的奥妙吧。

原来,后台有这么多的机械配合在一起,控制那些乐器发出各种美妙的声音。

看看那个黑色边框的大轮子就是主要的驱动轮,在它左边佛龛一样凹进去的地方就是放置乐谱的地方。乐谱则是像奏折一样的厚厚的一本,每一页,每一行都有不同的圆孔,每个圆孔控制不用的乐器发出声音。在这个装置的两侧,就是两个书架一样存放乐谱的架子。

呵呵,其实我觉得就是比较复杂一点的八音盒罢了。不过,洋人有这么大的决心做这个东东,我还是非常佩服的。

How to remove Hyundai I30 radio

My car is Hyundai I30 (2011) I lost my radio security code then my radio didn't work since then. following instruction are how to remove central control panel, take off the radio and get radio S/N then calculate the radio security code: 1. open up the top glove box and remove the matt at the bottom.  You can see 4 screws, remove these 4 screws 2. pull the glove box toward yourself, to take off the box from central control panel. 3. then you can see another screw just below the yellow mark, unscrew it     You don't need to unscrew the 2 screw in the front.  4. pull the whole central panel toward yourself evenly, then you can get off the cental panel.   5. read the last 4 digis from the S/N: 0087 (see above photo)     plus 1212 equals 1299     then you get your radio security code: 1299 -- Photos shared with Fish Bowl Photo. http://www.pixiereef.com
