Magnetic Stitch Badge

Magnetic Dtitch badge.

measures about 6.4cm (w) x 8cm (h) x 14cm (d) excluding the badge mount.

badge mount is 3mm deep

Wiring is basically the same as what i used for my set of Disney ears - apart from using separated neo pixels from the strip and soldering them together.

WLED Installer

https://install.wled.me/

This installer is web based and really easy to use.

Simply plug the ESP32-c3 to you pc via USB and then hit “install” on the web page.

It will show you a list of available connected hardware and allow you to flash the program to the Microcontroller.

Once flashed, you have the option to connect to your home network wifi - but I chose not to as I wouldn't use this badge at home.

(you can do this again later in the config)

WLED broadcasts it's own wifi AP which you can connect to via your mobile and then both program and control.

*Under LED Preferences, you need to update the no of LED's you have used and then hit save.

There are plenty of WLED setup guides available on Youtube if you need, else let me know and i can try make a video on the process.
