Simple vibration analyzer

A MEMS acceleration sensor is used to convert the vibration signal into a voltage signal. The MCU collects the voltage signal into the MCU through the ADC module. Then the time domain signal is converted into a frequency domain signal through FFT changes, and the conversion result is displayed through the OLED module. This basically completes the function of the vibration analyzer.

Open source SMU precision power supply equipment

The SMU is a precision power supply device that can measure not only high-resolution voltage sources but also high-resolution current sources. It also integrates bipolar voltage and four-quadrant output functions to facilitate testing of various characteristics. By providing a linear sweep voltage and sweep current, the IV characteristic curve of the instrument can be obtained.
