Meteor Dinosaur

Overview

I. Design Summary:
Primarily utilizes the HE4054B + TM1834 charging chips, allowing for battery-free operation at very low cost.
II. Hardware Circuit

: The charging circuit composition depends on the battery size, with the charging current designed accordingly. A standard 0.5C charging rate is achieved. The brightness of the

meteor effect driver IC can be adjusted by changing the resistance value of R7. III. Physical Demonstration: Red and white light effects are shown. The blue background causes the image to appear slightly bluish. IV. Installation Notes: The LED can be directly soldered on or magnetically attached using a sheet metal and magnet. (White LED is shown in the attachment .) V. Demonstration Video: White light effect video. Other colors are also possible, and color mixing is supported.
