DIY modified bus card sequence: Have you ever found that when you go to work in Shenzhen, especially during the morning rush hour, you squeeze the bus and can't help but squeeze it. Before you can squeeze in, , you see another bus coming and finally enters through the middle door, and then you start to ask other friends to help pass the bus card to the front to swipe the card, "Oh! How come your bus card is exactly the same as my bus card, which one is mine?" In order to solve this problem from the root, as an electronic engineer, I feel that I have an unshirkable responsibility. So I DIY the following global limited edition DIY PCB bus card. Text: I won't say anything more, just go to the pictures! (The picture of the original bus card is from Shijiazhuang, I forgot to take a picture of the original Shenzhentong card, but the principle is the same) This content was originally created by EEWORLD forum user Peng Binghao.

Are you sure you are using lead-free tin? Otherwise, it is environmentally friendly to use it every day!

Beautiful! Sink the chip in the middle and cover it with UV glue!

This is indeed a very necessary function. It should be promoted by bus companies across the country.

It should be made into a gold-plated board, which is high-end and classy.

Haha, immersion gold is too expensive. If I have more money in my bank card later, I will consider getting an immersion gold one.

Are you serious?

Why can't I see the picture even after I changed two browsers?

I really didn’t see the picture... If anyone has seen the picture, please post it again, otherwise brothers passing by won’t know what you are talking about.

Boss, are there any requirements for the line width and number of turns of the PCB?
