Mini DIY Hand Crank Generator Light Bulb STEM Science Experiment Kit & Education Model for Children Gift Toy Learning Project

ITEM NAME Mini DIY Hand Crank Generator Light Bulb STEM Science Experiment Kit & Education Model for Children Gift Toy Learning Project DESCRIPTON Suitable age: 8+ Product Features: By turning the large disc by hand, the generator is driven to rotate, and the output power is realized. Can light bulbs. Features: Interesting science and education works, exercise manual brain ability, show hand-cranked electricity function, light up low-power bulbs, and can also demonstrate the charging effect of mobile phones Consequence (because the current is small, it cannot be actually charged)

Step-by-Step Assembly Instructions

Step 1: Identify All Parts

Lay out all wooden plates, motor module, booster module, LED bulb, belts, screws, nuts, and wires included in the kit.

Step 2: Assemble Main Wheel Plates

Fix Plate 2 and Plate 3 onto Plate 4 using 8mm screws. Note: Place Plate 2 in the middle layer.

Step 3: Install Long T21 Pin & Large Gear Wheel

Insert the long T21 metal pin through the large gear wheel assembly.

Step 4: Lock Gear with T21 Pin

Push the T21 pin through the center gap of the wheel assembly from Step 3 to secure the 5# wheel plate.

Step 5: Attach 6# Wooden Bracket Plate

Mount the fan-shaped 6# plate onto the wheel assembly.

Step 6: Fit Large Rubber Drive Belt

Loop the large belt around the main crank wheel gear.

Step 7: Install 7# Support Plate

Attach the triangular 7# plate to the wheel assembly as a side support.

Step 8: Build Vertical Lamp Stand (Plates 10 & 11)

Stack and fix Plate 10 and Plate 11 with 7mm screws to form the vertical bulb holder frame.

Step 9: Wire Motor & Booster Module

Connect the motor and voltage booster module with the supplied red & black wires.

Step 10: Fix Motor Assembly to Base Plate 1

Secure the wired motor module onto the cross-marked 1# base plate using 4mm screws.

Step 11: Mount Bulb Stand Frame to Base Plate 1

Fasten the vertical bulb stand (from Step 8) onto base Plate 1 with 7mm screws.

Step 12: Install LED Bulb

Attach the white LED bulb to the top of the vertical stand and connect its wires to the booster module.

Step 13: Attach Crank Wheel Assembly to Base

Mount the full crank wheel unit onto base Plate 1, lock with 7mm screws.

Step 14: Fit Small Rubber Drive Belt

Loop the small belt between the crank wheel gear and the motor drive wheel.

Step 15: Final Full Assembly Check

Verify all wires are connected correctly, belts are tight, and all wooden frames are securely fastened.

Step 16: Install Bottom Rubber Feet

Stick rubber foot pads to the bottom of base Plate 1 to finish assembly.

Steam pushes turbines to rotate, converting thermal energy to mechanical energy. Turbines drive generators to turn mechanical energy into electricity.

Hydropower Plant Flowing water spins generators to transfer energy. Dams are commonly built with stone or concrete barriers for flood control and stable water flow regulation.

Nuclear Power Plant Nuclear fission inside reactors releases thermal energy. The heat generates steam following the same workflow as thermal power plants; the nuclear reactor replaces coal-fired boilers.

Wind Farm (Wind Power) Uses wind force to spin turbine generators. Wind power is a clean, renewable energy source.

Tidal Power Plant A branch of hydropower that captures energy from daily tidal water level rises and falls.

Geothermal Power Plant Extracts heat from underground hot rock layers, hot springs, and geothermal steam as its primary energy source. </ol>
