===========================
Wuwuwu It’s my first time to draw a PCB and make a board. I’m so excited that it can be used. Wuwuwu, although it’s soldering. I was still very excited when the second chip lit up. The first chip was tinned and there was no solder oil, so I couldn't remove it. Wuwuwu, the light didn't light up when I tried to put it on
. At first, I suspected that my board wires were not connected properly.
A long time ago, I was setting up a circuit in the Analog Electronics class. I knew it was free to build a 10x10 board, so I made an Ultraman type. Then my friend (we were a group) got angry when he saw it, and finally he did it. I didn’t touch the PCB anymore.
This time I wanted to try my own drawing board and play around with it. From the beginning I didn’t know how to do it, and I started to explore the stamp holes step by step. I didn’t know how to do it, so I just looked at other people’s findings and if I couldn’t use it directly, I fumbled and changed it, and then it looked like 3D. Wow, the time is spent and it’s rewarding. It’s still very nice.
It makes me feel the fun and I will paint more in the future. Hehe. Try more of everything.
I really feel that the drawing board is art, and it makes me feel good when it looks good.
Can my family members point out some places for me to learn from? Thank you.
