Hello! I would like to present the Bethlehem Star I made two years ago. The entire structure is made of sheet metal. There are 78 5mm LEDs in the drilled holes (34 red, 33 yellow, 10 green, 1 blue). The star's tail is the ne555 + cd4017 base configuration. Three series-connected LEDs are connected to each counter output. The center of the star is based on the layout in this topic https://www.elektroda.pl/rtvforum/topic1489666.html (2x ne555 + cd4017). Unfortunately, it doesn't work as it should. The resulting light effect (depending on the position of the potentiometers) is also nice, so I left it. The flashing green LEDs are connected to the output of one of the ne555. The star is finished with glued-on tissue paper balls.
Very aesthetic and solid workmanship. It looks very nice even without the lights. I like the integration of these LEDs into this rolled tissue paper. In the star, the lighting effect is very nice, dynamic but not aggressive. Well, only this unfortunate tail flies in reverse, as my colleague noted above. If it was flying from the star and it was still synchronized with the "eruptions" of the star, it would be great for me.
