説明
⭐ Never struggle with standard opaque LED matrices again! In this video, I'll show you how I designed and built a fully transparent 15x10 LED matrix on a flexible PCB using 150 WS2812B addressable RGB LEDs. From schematic design to animations, you'll see every step including how to keep the board see-through by avoiding copper pours, ordering from JLCPCB, and attaching it to a 3D-printed stand.
What You Will Learn in This Video:
1️⃣ Designing a transparent LED matrix schematic in Altium with 150 WS2812B pixels.
2️⃣ Routing a transparent flex PCB with no ground plane for maximum clarity.
3️⃣ Ordering transparent flex PCBs with SMT assembly from JLCPCB.
4️⃣ Connecting and testing the matrix with an Arduino Uno.
5️⃣ 3D printing a stand and frame to mount the flexible matrix.
