## Overview

The EUDAX DIY Dynamo Lantern is a compact, hand-cranked DC electric generator model designed for middle school and above. It demonstrates the conversion of mechanical kinetic energy into electrical energy, lighting up LEDs to visualize the process. Made from durable PVC and metal, it supports hands-on STEM education by allowing disassembly and reassembly, making it an ideal interactive teaching aid for physics and electricity concepts.

## Description

EUDAX DIY Dynamo Lantern Educational STEM Building model,Labs Demonstration Motor Activity Teaching Model Hand Cranked Power Electricity DC Electric Generator Physical Science Experiment Education - Hand Powered Specification: Item Name: DIY Hand crank generator model Size: 173 * 88 * 118mm \ 6.81 *3.46 * 4.64 in (L * W * H) Material: PVC plastic and metal Color: Multicolor (White \ Red \ Yellow \ Green) How to use： When using, use a belt to wrap the pulley and make the brush in good contact with the collecting half ring. Rotating the large pulley through the rocker drives the armature to rotate. At this time, one LED emits light, changing the direction of rotation, and the other LED emits light. It can be explained that a current is generated in the coil, and mechanical energyis converted into electric energy. This is an assembled hand-cranked generator model, primarily intended for teachers or middle school students (Recommended Age 14+). It is mainly used for educational demonstrations, showcasing how kinetic energy is converted into electrical energy through our model, and then transformed into light energy via an LED. This process enhances our understanding of textbook knowledge.Pay attention： 1. The wire and the collector ring and the LED soldering area should not be touched by hand to prevent the line from being disconnected. 2. After the experiment is completed, the belt sleeve should be removed on one wheel to prevent the belt from being loose and slippery. Package included: 1 Set Plastic Teaching Model（Already assembled）

Review: Hand cranked generator with rectangular coil also works as a DC motor - DC motor kit with rectangular coil assembly allows students to understand magnetism, forces and torques. The motor kit is marketed for its design as a generator. However, with just 6 volts DC on the brushes, the assembly acts as a DC motor. It is impressive to watch a cell phone video of the motor motion in slow motion! The assembly takes very little time as our shipped kit was preassembled and was ready to go. My student snipped the wire connections on the two LEDs for using the apparatus as a DC motor. You can always reconnect the LED wires to go back into the generator mode - if you wish to see red light or green light depending on the rotation direction of the crank. So, you can use this apparatus as a generator and watch the red or green diode light up - depending on the rotation direction of the rectangular coil. Or, as a DC motor - with a rectangular coil. Remember, the DC motor requires say, 6 volts ( using 4 of 1.5 volt AA batteries). After playing around with the generator, remove the durable rubber band from the hand crank with large pulley (which helps rotate the rectangular coil) . Then, connect the assembly to 4 AA batteries placed in series. Then watch the armature rotate! Do not forget to start the rectangular coil at an angle so that the two brushes individually touch the separate commutators. A small nudge of the coil is helpful to start the motor rotating - after connecting the battery in series to the brush connectors. Students will start to get the idea that the DC motor has an aspect that there is generator action going on here. This means that the generator emf goes against the current flowing in the magnetic rectangular coil. Therefore the spinning motor draws a smaller amount of current vs. the current that would flow if one blocked the rectangular coil from rotating. So students learn not to allow the motor to get stuck in one position, not rotate, and draw current that could damage the apparatus. This apparatus is alot of fun and a wonderful design to learn about motors and generators.
Review: Good Tool for Physics Labs - As a physics teacher, I used it in a lab with very little difficulty. Occasionally, the magnet(s) would fall out (middle- and high-school students can be a bit rough) and it took a little trial-and-error to get them oriented correctly. Also, sometime the rubber band around the pulley would slip. But all-in-all, it's a good tool for experimenting with a DC generator.

## Features

- Educational model - This is an assembled hand-cranked generator model that can be disassembled with tools to give student a better understanding of the model's construction.Through this package, They can exercise their own hands, thinking, exploring, creating ability,Build a project model that light up the LED by hand and the drive motor to learn the principle of conversion between energies.

## Questions & Answers

**Q: If you clamped the leads to metal handles, could it provide a shock?**
A: No, the electro motive force is too low to create a perceptible feeling.  The LEDs (red and green) probably turn on at about the same voltage (1.5 volts) as a small battery but at a much lower current (1 to 5 milli-amperes).

**Q: How many volts is this toy capable of generating?**
A: Probably less than 2 volts at normal cranking speed.
