Book: 機巧裝置 機構設計應用圖典 從零開始也能實踐簡易自動化

Purchased date: February 23, 2020



Finally received the book yesterday in EF Locker!  Actually this book was recommended to me in Taobao few months ago and I really wanted to read this!  It's not in the library and ebook not available, so I ordered from Taiwan (I was too chicken to order it from Taobao China due to the outbreak now).  The book and shipping costed HK$200.  I think it's worth it.  I consider buying this book for quite some time, because I don't like to stock up books at home, no space.  But, What I truly feared was that I couldn't understand any of it.

We afraid because we are ignorant.

It's mechanics.  I read some and it wasn't so bad of me.  It is actually a really good book for looking up the common mechanics.  So, I am quite happy I got this book.

Gear investigation: Klutz Lego Blender

Completion Date: May 31, 2020 After I finished with Banbao gears collection, I search on web for other building instructions.  I came across the Klutz Lego and saw the picture that I just built from looking at it.  It was quite easy and fast, however, I would like to convert it to vertical winding, but I don’t know how yet.  So here is the original one. Gear ratio is 40:8=40:24 = (40/8)*(40/24)=8.3 times faster then the hand-winding motion.
