Nightlight "Funny kitten"

Nightlight "Funny kitten" for our favorite kids.
It is simple to make and safe for children.
In this, it was chosen powered by batteries and completely closed case.
LEDs arranged in a circle form a beautiful pattern.
And in the daytime, it's just a happy kitten on the wall.
I use the DC-DC Converter 0.9V to 5V for full use of a single battery
The case is printed on the 3D printer.
