Part 1: Baby Mobiles with Arduino and LED’s

This is my first try of making some baby toys. Currently i am working on a diy LED baby mobiles. I decided that care bears would be a suitable subject, because they are in my mind since the 80s.

First i had to figure out how i can use the LED’s in this mobiles project. Due each care bear has a symbol on it’s chest, i decided to use the LED’s to make this symbol glowing.


Next i used google to find some nice care bear drawings which i vectorized afterwards by using viscut (my favourite laser cutting software). The hardest part was the post-editing of the vector drawings. For that task i worked with inkscape.


The figures consist of three layers. Two layers outside with engraved contours and a cut out of the chest symbol. The third layer is the middle layer, which will be placed between the  two outer layers. This middle layer contains a small acrylic circle, the LED, a resistor and some cables.


The LED is placed close to the acrylic parts outer edge. This leads to a very nice glowing of the chest symbol.

The first prototype worked! Now it’s time to order the needed parts and  make  the other figures for the mobiles. I am planing to control the LED’s over some kind of remote. More in the next part of the build log.

    1. Hallo Markus,

      sorry fürs sehr späte Feedback, aber mein Blog ist zur Zeit nicht sehr aktiv. Ich glaube ich habe die Bilder damals mittels Google gesucht und von Hand vektorisiert. Ich kann mal nachsehen ob ich die Dateien noch habe.
