My son(11) wants to have “jungle” is his room and he asked for Lion, which makes sounds and light. After some researching, I found some ideas and little but adjusted them and you can see result on attached pictures.
From engraving point of view very simple project, 2 pieces of 6 mm plywood, where I engraved Lion’s picture. Back part of lion is white, front is black. On back is applied flexible led strip.
In box on top is small controller based on Wemos D1 Mini ( 2 MB File system hosts Lions sounds), I2S amplifier, Speaker and PIR for sound activation. Automatic sound can be disabled for night, and Light can be started independently.
