DIY Dynamo Generator Model Wood Invention Science Experiment Kits Children Creative Educational Assemble Toys Features: 1. Scientific experiment toys exercise children's practical ability. 2. DIY small toys cultivate innovative ability. 3. Put education in fun, cultivate scientific knowledge; Specifications: Material: environmentally friendly wood, plastic and metal components Product size: 9.5x6x11cm/3.74x4.33x2.36inch Age of application: over 3 years old Type of toy: intellectual development Principle: The closed coil rotates in the magnetic field, and the inductive current is generated by electromagnetic induction, so the principle of its generation is battery induction. Methods of assembly: Step 1: stick four small squares to the four corners of the board with white glue. Step 2: glue the frame with white glue. The glue is not dry at this time. so we need to take it lightly and put it lightly. Step 3: connect the whole frame with glue. Wait for 15-20 minutes until glue to solidify. Step 4: after glue solidification, assemble the drive shaft with yellow sleeve clamp, small white rotating axis toward the inside. Step 5: install swing arm and drive wheel, and use yellow sleeve clamp. Step 6: tie the motor bracket under the skew beam with the strapping band, or put it flat on the board. Install the motor. Step 7: install a belt, a short belt for the top wheel, a long belt to connect the motor wheel and the top; Step 8: use double-sided adhesive to fix USB plate, red wire to positive pole, black wire to negative electrode, complete assembly. Because the circuit needs a steady current to start off, speed up a few laps (or pick up a belt bomb several times) until the lights turn on to slow down the speed. Notes: 1. This product does not contain paints and pen brushes. Batteries need to purchase by yourself. 2. Please allow 1-3cm measuring deviation due to manual measurement. Included: 1 X DIY Generator Model
