1. Why do I want to build this? I broke a transistor on its original PCB while tinkering, and now I want to make a smart RGB light to reuse the 5m led strip. I will control the LED strip with WebAP and use it as a staircase light at night. 2. Why do I want it to exist? My mom will get angry if I don't fix it before Christmas :( 3. Hardware that I need and cost: ESP32 C3 Supermini - Php 180 = £2.5 A2SHB SOT-23 - Php 51 = £0.7 Protoboard - Php40 = £0.5 1206 SMD resistors - Php 300 = £4.2 1206 SMD capacitors - Php 423 = 5.8 78L05 SOT-89 - Php 77 = £1.1 Soldering Iron - Php 240 = £3.3 3d printed case from a vendor = £3 Total = £25.6 4. Yes, I've touched hardware Here's my PCB V1 using KiCad and a sample Web UI https://drive.google.com/drive/folders/1KY--YpJZuwXoIxLG2a2wwAMXrDKIJiwd?usp=sharing
