This is the kit that I always wanted to make and my dream come true! Finally I can do my own engineering project I want to do and to keep. The Christmas Tree kit has light that you can turn on and off and this kit you will need to solder.
Step 1: Solder the Resistor
I forgot to take pictures when I solder the resistors, diode, and LEDs. First, solder the resistor to R1-R6. After you solder the resistors cut the excess leads. Solder one at a time so it will be easier for you to solder.
Step 2: Solder the Diode.
Solder the diode on D1. Cut the excess lead after solder on the board.
Step 3: Solder the LEDs.
Solder the LEDs on L1-L12. The longer lead is the positive and the shorter lead is the negative. The longer lead is going in the square solder pad and the shorter lead goes in the round solder pad.
Step 4: Solder the Slide Switch on the Pcb.
You just need to solder a little since they're small and you don't need to cut the leads when they're already perfect.
Step 5: Solder the DC Jack in the Pcb.
You will need to tape under the dc so it will be secure when soldering.
Step 6: 9v Battery Snap
Place the 9v battery snap and solder to the pcb. The red goes to the positive (+) and the black goes to the negative (-).
Step 7: You're Done!
Put the battery place on the battery snap and turn the switch on.
