It’s never too early to starting thinking about Halloween accessories. This Minecraft potion bottle by Arnov Sharma on Instructables would be great for Halloween, or really anytime of year!
Here’s something fun: the Potion Bottle from minecraft. This full-scaled model is equipped with an WS2812B circuit, which are all running blue-sky-blue color animations in a loop which imitates the liquid inside the potion bottle from the game.
In this case, the system is powered by an internal 3.7V, 2600mAh Li-on Cell coupled with a Power Management IC. It also features an XIAO microcontroller connected to eight WS2812B LEDs, all housed in a custom 3D-printed shell or body.
