Car remote control water sticker

Remote control is a kind of device used for remote control of machinery. The modern remote control is mainly composed of [2] integrated circuit boards and used to generate different messages It's made up of buttons.
The passenger car door remote control adopts the latest technology of encoding and decoding, and controls the solenoid valve of the door pump in the way of flashing to achieve the purpose of opening and closing the automatic door. It is used for bus (bus, CMB) remote control to open and close the door, so as to avoid the trouble that the driver needs to open the door every time. The main component of the emission part of the remote control is the infrared light emitting diode. It is actually a special [3] light-emitting diode. Because its internal material is different from ordinary light-emitting diodes, when a certain voltage is applied at both ends, it emits infrared light instead of visible light.
circuit design
In the remote control transmitting circuit, there are two kinds of circuits, encoder and 38kHz carrier signal generator. In the application circuit without multi-channel control, conventional integrated circuits can be used to form a few channels of infrared remote control transmitting and receiving circuit. The circuit does not need to use a more complex special encoder and decoder, so it is easy to make.
Remote control transmitter based on frequency division coding
It is difficult for ordinary electronic technicians or amateurs to use the special infrared coding communication protocol (color TV, VCD, DVD, etc.) as the encoder at the infrared transmitting end. However, for the remote transmitting circuit with few channels, the frequency division method can be used to make the coder, and for the remote control circuit with one channel, the 38kHz infrared signal can be directly transmitted without the encoder, The purpose of control can be achieved.
It is a one-way infrared remote control transmitting circuit. In this circuit, a 74hc00 integrated circuit of IC1 high-speed CMOS 4-2 input "and not" gate is used to form a low-frequency oscillator as coding signal (F1), and ic2555 circuit as carrier oscillator. The oscillation frequency is: F0 (38kHz). F1 modulates: F0, so the waveform of pin 3 of IC2 is intermittent carrier, The carrier is sent to space by infrared light emitting diode. The waveforms of key points a, B and B 'in the circuit are shown in Figure 2, where B' is the unmodulated waveform.
Water stickers, which can only be used after soaking in water. It is a new transfer technology that uses water as the carrier to separate the pattern from the backing paper and then transfer it to the substrate to realize indirect printing.
usage method
1. The model water sticker should first cut the required part from the whole paper and soak it in warm water for about 1 minute.
2. Then try to twist it with your fingers. Make sure that the glue between the surface layer of the plastic film and the backing paper has melted, and take it out of the water after the plastic film can be separated.
3. Place it near the position where the pattern needs to be pasted on the model, and gently slide the plastic film with the pattern from the backing paper to the surface of the model with your fingers. The backing paper can be thrown away.
4. After the pattern position is adjusted accurately, the residual water between the sticker and the model is sucked away with a sanitary swab, and the residual bubbles are extruded at the same time. Then put it in the air to dry, and the plastic water stickers printed with various marks can be firmly adhered to the surface of the model.
Use softener
Its function is like a mild dissolving agent, which can slightly "dissolve" the water sticker. In this way, the water sticker can be completely and tightly fused with the surface it is attached to. It can stick into the gap, cover the protruding rivet and circle the curve.
Once the softener is applied, be careful not to touch or move the water sticker, otherwise the water sticker may be destroyed. When the water sticker appears to wrinkle, it means that the sticker softener works, but it will shrink and return to flat after drying. If you see a bubble after drying, pierce it and reuse the softener. Although it doesn't work as well as the first time, it will help more or less when it can't be solved.
One thing to keep in mind is that different brands of softeners have different characteristics, and so do water stickers. Therefore, the "strong" softener may destroy the thin water stickers.
So before you don't know a certain brand of water sticker and sticker softener, you'd better try it on the unused water sticker first. When the water sticker is dry, cover it and the model with transparent paint of your choice to make it smoother. With luck, the water sticker will naturally blend with the paint and will not be affected when you start to dry sweep.
