Schematic and description of some electronic circuits I made:
- ESP32 self updating from web server
- PV string simulator to test grid solar inverters
- DIY Pick and place machine with OpenPnP
- Flash .hex files on Atmega without Arduino IDE
- Electromagnetic gun
- Flashing lamp circuit
- LT Spice repetitive signal
The description of many more electronic circuits is available in Italian in the list below.
At least you can see the schematic. If you have curiosity for a particular project, let me know, and I will translate it.
