Digital oscilloscope

This oscilloscope, built in a training camp using an STM32H750 core board
, encountered many difficulties.
1. Due to limited soldering experience, issues like solder bridging and missing solder joints occurred.
2. Lack of proficiency with a multimeter resulted in some continuity tests not being performed promptly.
3. Insufficient attention to detail during inspection led to the failure to spot a relay being soldered backwards, causing delays in project completion.
4. A lack of understanding of component melting points resulted in encoder malfunction after completion, preventing proper encoding.
(The encoder failed due to high temperature, so its use is not shown in the video. We hope the reviewers will understand and forgive this. Thank you.) (A new encoder has been installed, and the evaluation video has been uploaded.)
In this training camp, I also learned a lot:
1. Knowledge of analog electronics, such as NC representing normally closed circuits.
2. Drawing the circuit board requires creating the schematic diagram, which aids in subsequent inspection.
3. Remember to check by module after soldering for easier troubleshooting.
4. I also learned many soldering techniques, including handling solder bridging and the placement and soldering of multi-corner components.
I'm very grateful for the experience and opportunity this training camp gave me. I also want to thank the instructors and the helpful group members. Thank you all for your help! Thank you! Thank you!
This was a fantastic experience.
