Solidworks 自定义快捷键

还是写一下备份一下免得重新装了之后忘记, 而形成长期使用习惯可以提高不少效率


1, 先把滚轮方向反过来

2, 关掉状态栏, 不查看边线, SW越来越吃资源了, 也或许是电脑不够好

———————以下是快捷键, 左手操作——————

Google Glass 3D optical layout reconstruction, based on teardown information

中文读者请看  Google Glass 使用了哪种显示技术?具体是怎么实现的?

Chinese reader please hit this:


Since my major is Optical Engineering, I am very exciting about Google Glass, and also keep eyes on it from the beginning. Several months after introduced glass, the explore edition hit the developer. Some of them make a teardown test, even it was not a completely teardown, we can get lots of information from it.

This post is an original “research” article, based on teardown information that I can find in the Internet. Shows how we can get an almost complete optical layout from the information.


First, according to several hackers and developers[1][2][3][4][5], the hardware configuration is:


RAM: 682 MB

Display resolution: 640 x 360 pixel (very important information)

Internal storage: 16 GByte


Invensense MPU9150=Invensense MPU6050 (3 axis gyroscope + 3 axis accelerometer)+Asahi Kasei AKM8975 (3 axis geomagnetic sensor(compass))

LiteON LTR-506ALS rear-facing sensor(RFS) or “proximity” sensor

One more thing, glass support “wink” command, up to 20 winks!

So here is main information source from teardown test from Bill Detwiler [1] [5] <- hit it, very good articles. He opened the front shell ……

Figure 1 cracking open Glass from Bill Detwiler and TechRepublic. I think (a) the flexible PCB with white characters is the interconnection between these module; (b) the small connector near the prism is connected to RGB LED light source.

花了半天建了个Miller Transfer 的超长拖车

昨天看到youtube上面一个视频,超长拖车,看的感觉太爽了那个结构。一层一层的,激动之下就用查了下拖车的牌子,找到了几个图, 犀牛做了一个模型。如图。虽然细节还有些不够好, 但大体感觉对了. 拖车头的模型来自于

Last day occasionally saw a video in youtube, a heavy and long haul, very exciting. With the excitement i googled the brand of the truck, Miller Transfer, a U.S. company.

Then i modeled this long haul with Rhino and Vray, although the details not really fit in the actual truck, but generally i think that’s good enough. Trailer comes from
