This article will introduce the car inverter, including whether it affects devices such as batteries.Continue reading Is the Car inverter Harmful to the Battery?
Several transistor radios described in this article do not require battery power. They use high-frequency signals that are transmitted to the air by radio stations, and are rectified to obtain DC power, which is used as a power source for the radio. However, this kind of radio can only receive broadcasts of local close-range high-power radio stations; in addition, it must also use an outdoor antenna and a good ground wire; the earphone should use a coil impedance of not less than 2 kΩ.Continue reading Radio Circuit Using Powerless Transistors
Allegro MicroSystems (hereinafter referred to as Allegro), a global leader in power and sensing solutions for motion control and energy efficient systems, announces the world’s first three-phase BLDC driver IC A89331 with integrated power loss brake (PLB) This code-free, sine wave sensorless fan driver is designed to increase energy efficiency, reduce energy consumption and data center costs. The new PLB feature also increases data center security and reduces bill of materials (BoM) costs.Continue reading Allegro Introduces Three-Phase BLDC Driver IC A89331
On September 6th, Huawei launched the latest generation flagship chip Kirin 990 series at the Consumer Electronics Show in Berlin, Germany, including the Kirin 990 and the Kirin 990 5G.Continue reading Huawei Released the Kirin 990 Series Chip, Huawei HiS Chip Development History
You can see the presence of metal detectors in many public places such as airports and theaters. They are often for safety reasons to detect if someone is carrying a metal object that does not conform to the regulations. In this project we will design a simple metal detector circuit. There are many kinds of circuits for metal detectors, but most of them are more complicated, so here we use 555 timer to design a simple metal detector circuit.read more
This article will detail the LM324 amplifier. It is an operational amplifier (Op-amp) consisting of four channels. It is a low cost device with true differential inputs. For single-supply applications, the LM 324 is superior to other op amps. The LM-324 is capable of operating at voltages as low as 3V and high voltages up to 32V.
In addition to being comfortable and comfortable to wear, a sports Bluetooth headset is also very important. People from the sports Bluetooth headset frequency response curve, impedance, sensitivity, total harmonic distortion – THD can directly reflect the quality of the headphones to analyze the parameters .Continue reading These Sports Bluetooth Headsets are Worthy of Attention
