This short video contains the complete assembly of my electronic snowflake kit. The only tools are a soldering iron, tweezers and an optional scraper (for cleaning the board).
A few important notes:
1. The chip will have a little indention on one corner. Align this indented corner toward the center of the board. This will insure it is oriented the right way.
2. The LEDs have a green dot on one end. The LED outlines on the board also have a black dot on one end. Alight the green dots on the led with the black dots on the board. This will insure the LEDs are oriented properly.
3. Install the battery holder so that the opening faces the top of the ornament where the hanger hole is.
