#Call for Submissions# Colorful Wind Chimes

This project uses the Air001 chip and WS2812B to create a colorful wind chime-style string light. The current version has 3x3 lights, but theoretically it should have 6xN lights. You can extend and add more lights as desired. See the attached video at the bottom for a demonstration.
 
 
Project Introduction:
1. A charging circuit is provided (the chip used is IP5306, the reference chip for the MH-CD24 small board).
2. The main controller uses the Air001 chip, but actually uses the PY32F002AF15P6TU, which costs only 5 cents a piece with free shipping.
3. There are no strict requirements for the LDO; I used an H7333-3, but you can modify the circuit diagram and replace it with your own LDO
. 4. The four holes in the middle are for threading a rope to hang it, because there will be no Type-C port when using batteries.
5. The board comes with 6*3 diamond-shaped lights per batch. Cut them yourself; 5 pieces will give you 6*3*5=90 lights, which is 6*15mm long enough.
 
The image on the right is a humorous arrangement; this board is not actually in use.
 
Schematic Introduction:
As mentioned earlier, the PY32 is identical here; the Air001 is only used for schematic drawing.
The Air001 (PY32) is very useful; it only requires two circuits to run (some say one is enough, but this hasn't been tested), a true gem. For
 
the charging part, you can purchase the MH-CD42 or the IP5306 to build your own. (The seller sent the wrong item, which will be added later.)
The LED string part is a bit special because the LEDs need to be cut off, so it was made using a direct PCB design method; there's only one schematic.
For the LDO part, I just used a component I had on hand; a 5V to 3.3V converter should have many options.
 
Board Introduction:
It's worth mentioning that the three LEDs on each side were cut off with wire cutters; if possible, you can sand the edges.
I've also added a color-printed
 
3D introduction:
I sketched the 3D shell directly on the Fusion360 (mainly the six rounded corners) and then imported it into LCEDA for DFX drawing.
Panel Introduction:
As you can see in the image above, the board frame edges were left.
 
Software Components
: 1. The current default style is a rainbow breathing light
. 2. You can modify it to other styles.
3. Upload the completed code as an attachment.
