uhh i dont see card screenshots. This is just a photo of your BoM. i think you should make sure that you are not requsting the upper limit if thats not the achual cost

Design re-review submission

I updated my project for design re-review. This included:

  • Updating my BOM with links to my components on AliExpress
  • Making a 3D case model for my components in Fusion360
  • Updating my ReadMe with all changes

Hi! Cool project. Could you please design a CAD case if possible to make this qualify for Tier 4? Right now, you're mostly just putting a bunch of premade parts together. Additionally, is it possible to source your parts from websites like AliExpress (should be a LOT cheaper)? Finally, please ensure that you do NOT use AI in your README (we can tell). Thanks!

Designed my project, created code & Bill of Materials

I fully planned out my project and have documented all of it in my Github repo https://github.com/gethin101/Led_christmas_lights

-I researched compatible components and prices, and made a Bill of Materials with links to parts
-I drafted the GPIO wiring and breadboard layout for the Raspberry pi pico & other modules
-I planned out power distribution and voltage, ensuring a shared GND for all components
-I created template scripts in CircuitPython for the Pico, LEDS & DFPlayer Mini
-I decided on the initial commands for the LD3320's for voice recognition

Challenges / Notes:

  • Ensuring all components recieve the correct voltage
  • Correctly wiring the GPIO connections
  • Sharing power evenly - by limiting LED brightness

Below is my first design for the layout of the system

Set up project, github & decided on idea

I decided on my project idea - a christmas light setup with voice recognition, LED strip lights & christmas music playback.

I created my github repo and drafted my README to showcase the design & build process
And I planned out what I will need to do for the project.
