2. Safety Information

Warning:

• This product involves soldering. Welding type products require individuals to be 16 years of age or older and possess some knowledge of welding and circuits.
• Always use appropriate personal protective equipment, such as safety glasses, when soldering.
• Ensure proper ventilation in your workspace to avoid inhaling solder fumes.
• Be cautious of hot soldering irons and recently soldered components to prevent burns.
• Keep all components and tools out of reach of small children.

3. What's in the Box

Before beginning assembly, please verify that all components listed below are present in your kit. Refer to the image for a visual representation of the kit contents.

• Resistors (various values: 1KΩ, 10KΩ, 330Ω, 2.2KΩ)
• Capacitors (electrolytic)
• Transistors (S9014)
• Battery Holder (for 3 AA batteries, batteries not included)
• USB Power Cable
• Power Switch
• Nuts and Bolts for assembly
• Paper Instruction Manual (included in physical kit)

4. Setup and Assembly

This section guides you through the step-by-step assembly of your LED Flashing Christmas Tree. Patience and attention to detail are key for successful completion.

4.1. Required Tools (Not Included)

• Soldering Iron
• Solder Wire
• Multimeter (recommended for testing components and connections)
• Pliers (e.g., needle-nose pliers, diagonal cutters)
• Tweezers
• Cleaning Sponge or Brass Wool for soldering iron tip
• Screwdriver Set

4.2. Component Identification and Preparation

Familiarize yourself with the different components and their markings on the PCBs (Printed Circuit Boards). The kit includes two tree-shaped PCBs (MR-A and MR-B) and one square base PCB.

Important Note on Resistors: Some kits may include clear LEDs that require different resistor values for optimal brightness. For R2, R4, and R6, it is recommended to use 220 ohm resistors. The kit typically supplies 2.2K ohm resistors for these positions, which may result in dim lights. R1, R3, R5 should be 10K ohm, and R7 should be 1K ohm, as supplied.

4.3. Soldering Steps

Follow these steps carefully. Solder components one by one, ensuring correct polarity and good solder joints.

1. Solder Resistors: Begin by soldering all resistors onto the MR-A and MR-B tree PCBs according to their marked positions (R1-R7). Pay special attention to the recommended 220 ohm resistors for R2, R4, and R6. Resistors do not have polarity.
2. Solder Capacitors: Solder the electrolytic capacitors. These components are polarized; ensure the longer lead (positive) matches the '+' marking on the PCB, or the stripe on the capacitor matches the negative marking.
3. Solder Transistors: Solder the S9014 transistors. Ensure their flat side aligns with the flat marking on the PCB.
4. Solder LEDs: Solder the 36 LED diodes onto both tree PCBs (D1-D18 on each). LEDs are polarized. The longer lead is positive (+), and the shorter lead is negative (-). The flat edge on the LED casing also indicates the negative side. Ensure correct orientation. It is recommended to solder one lead first, then adjust the LED's position before soldering the second lead.
5. Assemble Tree Structure: Once all components are soldered onto the MR-A and MR-B PCBs, carefully interlock them. The connection points are clearly marked. Ensure they form a stable 3D tree shape.
6. Connect to Base PCB: Solder the assembled 3D tree structure onto the square base PCB. Ensure the arrows on the tree PCBs align with the arrows on the base PCB for correct orientation and power flow.
7. Solder Power Switch: Solder the power switch onto the base PCB. Be careful to orient it correctly as per the PCB markings.
8. Connect Battery Holder/USB:
   • Battery Holder: Thread the red and black wires from the battery holder through the designated holes on the base PCB. Solder them securely, ensuring red wire connects to positive (+) and black to negative (-).
   • USB Power: The kit also supports USB power. Connect the provided USB cable to the appropriate port on the base PCB.

9. Final Checks: Before powering on, visually inspect all solder joints for cold joints, bridges, or incorrect component placement. Use a multimeter to check for continuity and shorts if you have one.

5. Operating Instructions

Once assembly is complete and verified, your LED Flashing Christmas Tree is ready for operation.

5.1. Powering On

• Using Batteries: Insert 3 AA batteries (not included) into the battery holder, observing correct polarity. Flip the power switch on the base PCB to the "ON" position.
• Using USB Power: Connect the provided USB cable to the USB port on the base PCB and plug the other end into a compatible USB power source (e.g., a USB wall adapter, power bank, or computer USB port). Flip the power switch to the "ON" position.

The 36 multi-color LEDs will begin to flash in a dynamic pattern, creating a festive display.

5.2. Powering Off

To turn off the LED Christmas Tree, simply flip the power switch on the base PCB to the "OFF" position. If using batteries, you may also remove the batteries for extended storage.

6. Maintenance

The Cermant LED Flashing Christmas Tree DIY Kit requires minimal maintenance to ensure its longevity.

• Cleaning: Use a soft, dry cloth to gently wipe dust from the PCBs and LEDs. Avoid using liquid cleaners or abrasive materials.
• Storage: When not in use, store the assembled tree in a dry, cool place, away from direct sunlight and extreme temperatures. If using batteries, remove them before long-term storage to prevent leakage.
• Handling: Handle the assembled tree with care to avoid bending or damaging the soldered components or PCBs.

7. Troubleshooting

If you encounter issues during or after assembly, refer to the common problems and solutions below.
