Hello :)
I present to you another implementation of a Christmas decoration. The project was created for Christmas 2021. I used 12V LED "neons" for construction. The animation (hand waving) is controlled by a simple generator circuit based on CD4093. The main structure is a circle with a diameter of approx. 114 cm, cut from 30 mm thick Styrodur. There is an aluminum frame mounted on the back for mounting on the wall. In terms of electricity, there is nothing groundbreaking here, but making the decoration itself is very time-consuming and requires a lot of patience. This decoration is adapted to work in outdoor conditions.
This is what the decoration looks like on the front
And so at the back
In the lower left part, in this small plastic housing, there is a system responsible for waving the hand. You can see the protruding potentiometer knob for setting the swing speed. The power supply is mounted on a horizontal aluminum beam.
Below is a video showing how the system works. The film does not reflect the colors of the light well, in fact they are much better.
Regards
