[DIY Optoelectronic Design] Winter Olympics Snowflake Lanterns

This is the situation. The Winter Olympics entrance ceremony is so beautiful. The national snowflake lanterns directly hit my aesthetic point and made me like it very much. No, since I have used Lichuang EDA, and I will pay at a super low price of 1 yuan. Proofing, so why not make one yourself?

I'm young and don't know how good my sisters are. I think snowflakes are treasures. My sisters are also very beautiful!

The first step is to find a photo of the snowflake lantern from a suitable angle.

It seems that the snowflake lanterns at that time had about 2,000 small lamp beads. It is indeed difficult for me to reproduce the painting within 10 centimeters, so I can put as many lamps as I can.

I found a suitable photo in the grand event at Station B. The link to "Grand Event" is at 30 minutes and 35 seconds in the first episode.

Import the screenshot photos into SW as a reference

Then simply outline the shape, then mirror it up and down, then make a circular array, then cut off the excess lines and stretch them to look like the following

After checking it, it looked okay, then I made a engineering drawing, dragged the upper view to the engineering drawing, and then saved it and exported it to DWG format.

Open this DWG file in CAD and save as DXF format

Come back to Lichuang EDA to import the DXF file as the border layer

Then the border is ready! Import all the lights into the PCB and then layout them. If the drawing is stuck, you can turn off the real-time DRC detection and unnecessary layers.

If you find it troublesome to draw pictures, you can find a junior fellow student (suddenly you feel that I am good or bad)

After receiving the goods, because manual welding was too troublesome, I went to Taobao to buy a steel mesh for more than 20 yuan. Of course, after considering the improvement, I used Jialichuang's SMT patch, which is more convenient!
