All the pads are tin-plated and it is of high-strength material. 4Circuit working voltage: DC5V 5Number of components: 70 6Number of solder joints: 94 7Function\/feature: Adjustable eye-protection lamp 8Sample welding time: Approximately 55 minutes. In this kit, L1 and C2 use the copper - clad traces on the printed circuit board to form inductors. You don't need to make the inductors by yourself, which is simple and has a very high success rate! The circuit only uses more than a dozen components. As long as the installation is correct, it generally works properly. After installation, connect the power supply. Adjust the potentiometer until it just stops making a sound (when not near any metal objects). Then, bring the printed - circuit - board antenna close to a metal object. At this time, it should make a sound and stop when moved away from the metal. If it doesn't stop making a sound when moved away, turn the potentiometer counter - clockwise a little bit and try again until it meets the requirements. 1PCB board size: 6661 mm 2PCB board thickness: 1.6 mm 3Board material: It is made of international standard sheet materials. All the pads are tin-plated and it is of high-strength material. 4Circuit working voltage: DC 3V 5Number of components: 13 6Number of solder joints: 28 7Function\/feature: high frequency oscillation + buzzer 8Sample welding time: Approximately 15 minutes. Under the control of the single - chip microcomputer program, for the 32 colorful LEDs, when a pin of the single - chip microcomputer outputs a low - level signal, the corresponding LED lights up. Each LED can be programmed to light up at each moment, and then the continuously lit LEDs combine to present a colorful and dazzling animation. Using a 51 single - chip microcomputer to control LEDs is also a basic entry - level learning content for single - chip microcomputer learning. It is suitable for beginners and enthusiasts of single - chip microcomputers, helping to enhance their interest in single - chip microcomputers and improve their soldering skills. 1PCB board size: 7485 mm 2PCB board thickness: 1.6 mm 3Board material: It is made of international standard sheet materials. All the pads are tin-plated and it is of high-strength material. 4Circuit working voltage: DC 4 - 6V 5Number of components: 72 6Number of solder joints: 226 7Function\/feature: SMD adjustable flash LED 8Sample welding time: Approximately 35 minutes. This kit is mainly composed of a clock generation circuit and a decimal counter circuit. There is a self - excited multivibrator centered around the NE555. The power supply charges the capacitor C1 through R2, R3, and R4. When C1 starts to charge, pin 2 of the NE555 is still at a low level, so the output pin 3 is at a high level. When the power supply charges C1 through R2, R3, and R4 to 2\/3 of the power - supply voltage, the level of the output pin 3 changes from high to low. The internal discharge tube of the NE555 conducts, and the capacitor C1 discharges through R4, R3, and pin 7 of the NE555 until the voltage across C1 is lower than 1\/3 of the power - supply voltage. Then the level of pin 3 of the NE555 changes from low to high again. C1 is charged again, and this cycle forms an oscillation. The charging time is: 0.695(R2 + R3 + R4)C1, and the discharging time is: 0.695(R4 + R3)C1. Adjusting R4 can control the output frequency of the oscillator. The clock oscillation signal of the NE555 is continuously applied to pin 14 of the CD4017. Ten LEDs are connected to the ten output terminals of the CD4017. When the ten output terminals of the CD4017 alternately generate high levels under the action of the clock signal, D1 - D10 are sequentially lit up, thus creating a chasing - light effect. Adjusting R4 can adjust the flowing speed of the LED lights. 1PCB board size: 5421 mm 2PCB board thickness: 1.6 mm 3Board material: It is made of international standard sheet materials.

The Tesla coil is a kind of transformer (resonant transformer) that operates based on the principle of resonance. It was invented by Nikola Tesla, a Serbian-American scientist, in 1891. It is mainly used to generate alternating current electricity with extremely high voltage but low current and high frequency. The Tesla coil consists of two sets (sometimes three sets) of coupled resonant circuits. The Tesla coil is difficult to define precisely as Nikola Tesla experimented with a large number of different configurations of coils. Tesla carried out innovative experiments with these coils, such as in electrical lighting, fluorescence spectroscopy, X-rays, high-frequency alternating current phenomena, electrotherapy and wireless power transmission, as well as the transmission and reception of radio signals. 1PCB board size: 3016 mm 2PCB board thickness: 1.6 mm 3Board material: It is made of international standard sheet materials.
