01 / Overview

Semiconductors and logic gates are two very important concepts in electronic technology. Semiconductors are materials with conductivity between conductors and insulators at room temperature, characterized by dopability, thermal sensitivity, photosensitivity, negative resistivity, temperature, and rectification. Logic gates are the basic building blocks of digital circuits, widely used in fields such as computers, communications, control, and digital instruments. Common logic gates include AND gates, OR gates, NOT gates, XOR gates, etc.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

Semiconductor: a material with an electrical conductivity between that of a conductor and an insulator. The conductivity of semiconductors can be adjusted by controlling the concentration of impurities in their materials. This control method is called doping. Doped semiconductors can be used to manufacture various electronic devices, such as photodetectors. Semiconductors have characteristics such as dopability, thermal sensitivity, photosensitivity, negative resistivity temperature, and rectification. 1. The conductivity is not as good as metals and conductors, but stronger than insulators; 2. Charged carriers are mainly electrons and holes; 3. The insulation performance can be changed by doping; 4. Strong photoelectric effect, which can be converted into optical signal output. 5. Semiconductor devices have autonomy and are easy to control. Logic gate: One of the basic components of electronic circuits, used to perform logical operations. A logic gate is composed of multiple transistors, which can be controlled to turn on or off a circuit. The output of a logic gate depends on the state of its input signal and the function of the gate. Common logic gates include.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
