This article shares the whole process of a wireless LED light DIY. This wireless LED light is simple to make and can be used to demonstrate and study the principles of electromagnetic induction. Making materials is also very easy to get. Is it very interesting, what are you waiting for?
This version uses a powerful high-frequency switching transistor (BD139), and powerful transistors can enhance the effect. The so-called "the stronger the responsibility, the greater the responsibility."
Therefore, the use of this device requires great care and cannot be used near any sensitive electronic device (especially hard drives) because it is capable of generating high frequency environments, which can easily damage your gadget! Take appropriate safety measures with the work of the transformer and use insulated bushings as there is a danger of electric shock. (instead of using a power adapter or battery).
This wireless LED light is simple to make and can be used to demonstrate and study the principles of electromagnetic induction. Making materials is also very easy to get.
material:
1.2x2 åŒ coil
2.33k resistor
3. A 100nF capacitor (code: 104)
4.100μH (microhenry) inductor
5. One LED (red/orange/red patch works best)
6.BD139 transistor (or the same function)
7. Bridge rectifier (purchase my 1N4148 diode)
8. A perforated plate (3x3cm)
9. Wire, Tin, Power (6-12V)
The first step: collecting materials
With the development of the times, the consumption level of people is gradually increasing. At the same time, people's entertainment methods are beginning to diversify, especially for modern young people. As a result, different kinds of electronic products are starting to be in people's lives, and the booming Electronic Cigarette industry reflects this.
Described including the upper shell, the upper shell at the top of the smoke outlet, as described in the bottom of the upper shell with airway, described with the smoke outlet in the airway and also to match the upper shell, the lower part of the shell described the airway in the direction of the lower shell extension, as described in the lower shell near one end of the upper shell is equipped with oil mouth, described the lower shell with batteries, described at the bottom of the bottom shell has come in The air port is provided with an oil storage bin in the lower shell, and the air passage passes through the oil storage bin and is provided with a heating atomization bin at one end away from the smoke outlet. The utility model has beneficial effects: it can meet the smoking habit of different users, avoid the premature end of the use experience caused by excessive consumption of smoke oil, and indirectly prolong the service time and life of the product.
