Let's watch a demo first! ??

Background

Recently I got obssesed with 3D printing, and then stumbled upon this collapsing light saber design which I found really cool and could be a great practice for 3D printing beginners, so I 3D printed this with my Ender 3 V2 and with yellow and silver filament. The result came out fantastic! 

However, as an software engineer, how can we just stop here? 

So I measure the length and width of the saber hilt and found that the AMB02 (RTL8710AF) IoT dev board from Realtek can fit in just nice and work very well with WS2812 Neopixel LED strip, so here it is, a programmable and potentially IoT-capable Light Saber with RGB LED inside!

No matter how hard I tried to hide it, it eventually fallen into the hand of my son who really love changing its color by pressing the button while walking on the street XD   

How to get started?

You may download the

• Arduino Sketch Code
• Circuit Connection
• 3D model for the saber

from the links below. Then you just need to use your creative hands to piece them together and upload the code to microcontroller using Arduino IDE, that's it~

Hope you have as much fun as I did before! Happy making~
