When designing PCBs, you may encounter various issues, such as the most common problem of cold solder joints. Many times, the signs of cold soldering are quite obvious, but unfortunately, the average person’s eyesight cannot detect them immediately. Therefore, this video teaches you how to DIY a low-cost digital microscope that can output video signals via HDMI and capture video clips at 1920×1080 @ 30fps. It can be modified to install different lenses, allowing you to adjust it as needed.
This digital microscope is a low-cost digital microscope powered by Raspberry Pi Zero W. It uses the Raspberry Pi camera module and smartphone macro lens to provide excellent image quality, and it can adapt to your different needs.
Although aluminum has been used for the base plate and knobs in the video, most other parts can also be obtained through 3D printing.
The required components include:
-
1×Raspberry Pi zero w
-
1×Camera Module V1.3 (sensor directly mounted on flexible fpc)
-
1×12mm rod (approximately 140mm long)
-
1×5mm rod (approximately 42mm long)
-
1×20x macro lens
The following video clearly shows the samples that can be magnified, which is fantastic. You will definitely love this project.
