1. Use your brain to know that the fan can't mine... Graphics card has powerful parallel computing power, which is much more efficient than CPU when it is used to mine. In the past, many people used to mine with graphics card, resulting in the high price of a card. But now, bitcoin is collapsing. No one is digging. In the later stage, people didn't have to dig with graphics cards. They used specially designed circuits and quick miners. They couldn't even earn their electricity bills.

6. Gywbp6 rotary speed relay calibrator for speed measuring and resial voltage measuring is a special PWM waveform generator with 16 bit frequency accuracy, 24khz carrier frequency and independent amplitude control; The microcomputer is used to control and display the frequency and speed. It can check the speed relay of gear disc speed measuring type and resial voltage speed measuring type at the same time. It is an ideal device for calibrating the speed measuring relay of the toothed disk. The device has the advantages of low power consumption, high intelligence, convenient adjustment, small volume, light weight and easy to carry
the calibration device of rotating speed relay based on gear disc speed measurement and resial voltage speed measurement integrates frequency meter, voltmeter and rotating speed testing instrument, which is a multi-purpose rotating speed monitoring instrument
high performance microprocessor CPU is used as the core measurement device for speed measurement, which has the characteristics of high measurement accuracy and strong real-time performance
the measurement and control accuracy of the device only depends on the error and stability of the crystal oscillator, so the outlet value of the rotating speed contact can be kept unchanged for a long time;
