Update Log

2024-07-15: Added demo video

introduction.
To allow fans of Liu Yifei and her idols to experience the joy of having their goddess by their side, the project has been open-sourced. Next, I will guide you step-by-step on how to create this set of merchandise for free. No computer or embedded systems knowledge is required; just follow my steps. For
detailed demonstrations and the production process, please see Bilibili: "Make Your Own Liu Yifei Merchandise—How Programmers Follow Their Stars?"
For complete beginners (never used PCB before)
:
If you have never used LCSC before, the PCB (free shipping) and components (free shipping) were all free during a previous promotion. I don't know if they are still free now. If you encounter any coupon issues, remember to ask customer service. To
place an order
, use the Gerber in the attachment. After placing the order, you will receive the PCB as shown below in about five days. Just cut the connection with a knife. The front and back of the PCB are printed with different pictures, so it is equivalent to getting two sets of boards for free.
Phone
stand

[ ] Note: The phone stand in version v1.0 is relatively loose. The next version will be optimized. Attach magnets to the back of

the refrigerator
magnets. You can buy magnets directly on Taobao or Pinduoduo. The price is not expensive: 6mm * 2mm 20 pieces for about four yuan.
Bookmarks
can be made to look better after adding wadding. Pendant for
beginners
(can solder)
: Pay

more attention to LCSC's promotions. The promotions will occasionally give away free color silk screen printing coupons.
If there is no free coupon, 10 PCBs plus shipping costs 56 yuan.

Order

NFC Chip: To enable NFC functionality, you need to purchase an NFC chip, which costs approximately 3 yuan.
Image editing: The image layers are determined by the order in which they are placed; the image should be as clear as possible; LCSC EDA does not support image editing functions, so if possible, process the image in Photoshop before importing.

Soldering

tools: Requires solder paste and a hot air gun/heating station.
Testing: If you find that NFC cannot be recognized, it is most likely due to poor soldering. Please carefully check for cold solder joints, bridging, or incorrect chip orientation.

NFC App :

You need to download an NFC app on your phone.
Android: NFC Tools Pro, NFC Tag Assistant.
Apple: NFC Tools, NFC.cool.



Effects:
The following only shows the effects, all features brought by the NFC chip. For more usage methods, you can search "NFC chip play" on Xiaohongshu to view more usage instructions.
Music playback, making
phone calls:
I want to make a phone wall with photos of different family members printed on it, so that my illiterate grandmothers can easily call us.
One-click drama
control, smart home:
Just place it on the bedside table before bed to automatically enter sleep mode.
