Replicating FlowIO in CHINA 🇨🇳

Updated: Mar 20

I tried to reproduce FlowIO by myself in 2022. I have most electronic components prepared and 3D printing parts ready. But gives up eventually due to unable to buy a few key components. One thing I learned is: to make sure you can have everything in the BOM accessible before starting work. Here are some parts I was unable to get throughout and some parts need some effort to get in China.

( The following are tips for Chinese friends, I will use Chinese for your convenience。)

我在2022年的时候尝试过组装FlowIO。 当时几乎凑全了所有的零件也做好了3D打印件,但是由于几个关键性的零部件买不到,最终放弃了组装。以下是我始终没能买到的,和比较难买到的零件,中国的朋友们如果想组装,一定要确保自己买得到BOM里所有的零件。

我先是在淘宝里搜索但是没有商家卖,随后尝试过使用 Ali 在 Bill of Materials 页面提供的Mouser Electronic 的网站里购买,购买成功了,但是因相关进出口管制规定没能清关,被退回了,随后尝试在国外的另外一家大型的电子零售网站 Digi-Key 购买,但是依然因为相同的原因没能拿到手上(2023年3月10日查,Digi-Key里没有Adafruit Feather Sense nRF52840的现货补货时间未知)。

Don't forget to activate the "Raft and Skirt" function when you use the Raise3D Pro3 printer to make the PLA enclosure. Otherwise, the finishing may look less delicacy.😭
