*About Power Supply here:

This is my DIY power supply version, you can check my video above if this is first time you see it :)

I'm using Fusion 360 to design 3D the box and then print it with Ender 3 Pro 3D printer.

Total time to design and print about 4-5 hours.

Connect the controller and LED board to the 3D box. It's can be run with 3.7V-12V DC, and I'm using 9v battery here. And we're also adjust the delay time through potentiometer!
