Homemade Lamp (TX-13) ⭐ · ~15 min

⚡ Principle This kit demonstrates a simple electrical circuit. When you flip the knife switch, the circuit closes, allowing electrical energy from the batteries to flow through the wires and transform into light energy through the bulb.

🔩 Parts

Decorative lampshade ×1

Light bulb ×1 + Lamp holder (socket) ×1

Battery holder with knife switch ×1

Wooden boards (base, bracket, and top)

Cap screws ×2

📋 Steps

1. Assemble the bracket and the base for the lamp by interlocking the wooden pieces.

2. Assemble the top plate and the small support feet of the lamp.

3. As shown in the figure, put the bulb through the small hole of the top plate to connect it to the lamp holder, then install the battery holder.

4. Secure the battery holder to the top plate with screws, and finally place the decorative lampshade over the structure.

⚡ Fun Fact! The first light bulbs only lasted about 40 hours. Today, some LED bulbs can last over 50,000 hours—that’s almost 6 years of continuous light!

💚 Tip The lampshade is delicate. Handle it with care while fitting it over the bulb to avoid any creases or tears.
