Badminton training monitor

My initial idea for the "Badminton Training Device" project was to sense the form and intensity of the racket swing, whether it hit the badminton and where it was hit, etc., record the quality of all swings after a game, and combine it with the host computer to make a badminton shot. Play the practice analysis system. The MLC and FSM modules in LSM6DSOX can analyze and identify actions, which greatly reduces the data processing requirements of the MCU and can save resources to complete prompt or record functions.

HEGduino: Measure real-time cerebral blood oxygen levels (all open source)

Uses infrared light sensing to determine changes in blood oxygen levels in the brain in real time. Use the device in less than ten minutes to learn how to directly change blood flow to your brain. Neurons do not store energy, so regional brain activity is closely related to changes in blood oxygenation, where healthy blood flow patterns are essential for high function and growth of the brain.

200 W Game Console AC-DC Adapter GreenPoint® Reference Design

Robot arm gesture tracking and voice control system design

This project uses LSM6DSOX high-performance sensor and LIS25BA high-precision bone conduction sensor to control the four-axis robotic arm. By combining FMS and MLC with LSM6DSOX, the robotic arm can grab and put down items. Through LIS25BA, the vibration can be recognized and the steering gear can be controlled to complete the corresponding actions.

DIY handheld gamma ray spectrometer based on Raspberry Pi Pico

Although Geiger counters can be used to detect amounts of radiation, and with some tricks can also differentiate between the three types of radiation (alpha, beta, and gamma), their use is limited in identifying radioactive materials. For this purpose, gamma-ray spectrometers come in handy.
