Testing the temperature of steel billets before rolling is an important measure to ensure the quality of steel. Traditional manual testing is difficult to ensure product qu...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
Abstract: Aiming at the needs of coal-rock acoustic emission signal monitoring system, a data acquisition circuit with 24-bit resolution and 16-channel synchronous data acquisition function is desi...[Details]
Temperature compensated quartz crystal oscillator (TCXO) is widely used as a high-precision frequency source in communication systems, radar navigation systems, precision measurement and control sy...[Details]
In recent years, with the increasing maturity of LED technology, LED light sources have been increasingly widely used due to their advantages of using low-voltage power supply, low energy consumpti...[Details]
Multimedia processors are often the most power-hungry devices in portable electronic devices. Common ways to reduce CPU power requirements are to reduce clock frequency or operating voltage, but th...[Details]
