Automatic Charging for Kids Toys on Shelves

Idea:

In every home their will be kids an age of 1-10 years. They use to play with toys in day time and keeps in selves at night, during these free time if they charged with wireless charging then they can reused in the next day. This wireless charging will be interesting to the kids any they also plan and can give ideas too. All the toys are battery operated so they require rechargeable batteries; these batteries are charged with wireless charging when they are not in use. Generally children play with two or more toys so if one is used other is kept at charging point.

Method of Making:

• The wireless transmitter modules is take as a charging pad and is shown in figure 1 below.

• Fit the receiver into the toy by removing its cover and selecting proper place for placing the Wireless power receiver module. For the selected toy the receiver placed in a proper position is shown in figure 2. A DC-DC booster is used to charge the battery and operate the motors in toy. A rechargeable battery 3.7 V is also fitted inside the toy to keep away the Kids from batteries keeping in mouth.
