As Wang Wenwei is the inventor of electronic building blocks, he is good at developing new functions of electronic building blocks. The power supply mode of the product ranges from single dry battery power supply before 20 10 to solar power supply before 20 13, and then to manual power supply. Vibration, temperature control and other unique control methods are added. Formed the second generation of electronic building blocks developed later. As these products newly developed by Mr. Wang have applied for patents, they are protected by national patents. Therefore, electronic building blocks from other manufacturers dare not be copied. 1, products recommended by the special fund for Chinese teaching assistants. 2. The newly introduced electronic building blocks adopt LED lights, and a protective cover is added around the lights to prolong the life of the lights and protect them from heat. The battery cover is fastened with screws to avoid the consequences of children eating by mistake when the battery comes out of the battery compartment; 3. This product consists of non-toxic plastic blocks, which are used to install electronic components such as resistors, capacitors, diodes, triodes and integrated circuits. Using PPTC (self-recovery insurance) technology, even if the wrong assembly causes short circuit, there will be no danger of module overheating or even battery explosion; 4, the detailed color map assembly manual, you can understand it at a glance, you can spell it, and it is easy to learn; 5, can be quickly assembled: electric lights, electric fans, flying saucers, musical doorbells, alarm clocks, FM radios, tape recorders, karaoke accompaniment, loudspeakers, etc. , quickly enter the wonderful electronic world in relaxed entertainment.
