Three blue 3D-printed electronic enclosures are displayed on a black surface. The left and right designs are marked with red Xs, indicating failure, while the center design has a green checkmark, showing success.

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. So, I started with the most intuitive one, in my opinion, TinkerCAD. It looks like just dragging a few boxes around. ...

My First 3D Printer Creality Hi & 3 Failed Prints on My First Try!

Recently, I got my first 3D printer, the Creality Hi. I believe the usual first 3D print for a beginner should be the 3D Benchy. The printer itself even came preloaded with the model.

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. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31) CH340 Driver Issue and Fix.

To fix it, I had to uninstall the 3.8 version driver, and install the previous 3.4 version driver. ...
