As all the products in this series are handmade, they cannot be compared with those produced by mechanical industrialization in terms of dimensional accuracy. For buyers with high requirements for dimensional accuracy, please purchase with caution!

This series of scientific small creations is not merely about making a few structural small toys. The greater hope is to provide children with a platform-like foundation, allowing them to carry out more innovative designs based on these small creations!

External remote control is a wireless and non-contact control technology, which has significant advantages such as strong anti-interference ability, reliable information transmission, low power consumption, low cost and easy implementation. It is widely adopted by many electronic devices, especially household appliances, and is increasingly applied to computer systems. Since infrared rays are invisible light, they have little impact on the environment. Moreover, the wavelength of infrared light waves is much shorter than that of radio waves. Therefore, infrared remote control will not affect other household appliances or nearby radio equipment.

   The emission circuit of infrared remote control uses infrared light-emitting diodes to emit modulated infrared light waves. The infrared receiving circuit is composed of infrared receiving diodes, transistors or silicon photovoltaic cells, which convert the infrared light emitted by the infrared transmitter into corresponding electrical signals and then send them to the post-amplifier.

This set of materials can clearly and simply demonstrate the basic principles and functions of infrared remote control, transforming profound scientific principles into simple life phenomena.
