My First 3D Design using TinkerCAD.

Since I got my first 3D printer, I want to learn 3D design to make my own model to solve my own problem. I don’t know how to start. I think I should start with something simple. Simple means easy, right? I have a DIY human presence sensor using an ESP32 and LD2410C. It’s in a very raw state. I want to make a simple case for it.

How to Fix CH340 USB to Serial Driver 3.8 version issue.

Recently, I started working with the ESP-01S module and CH340 ESP programmer. However, when I tried to upload a new Arduino sketch, I encountered an error: A fatal esptool.py error occurred: Cannot configure port, something went wrong.
