Thanks for the video! Have you encountered with OV2640 camera module overheating? I have 160-degree camera, which overheats in less than a minute after using it. I have not glued it to MicroSD slot as you did, just wondering if it will help, if camera is glued to MicroSD slot. Also, have you tried to run these cameras in long term? My camera overheats and FPS drops down also image gets darker with green/blue color overfilling.

@ThatProject

3 жыл бұрын

It's common for FPS drops to occur due to bottlenecks, but it is strange for FPS drops to occur due to usage time. I doubt there is a problem with your ESP32CAM board.

Thank you for a very good video. I have a question, for example I need to recognize the figures on my counter, but don't have enough space between camera and counter itself. Could you recommend something for me. I would like to have a good picture of figures for recognition and distance between counter and camera should be 2-3 inches.

@ThatProject

3 жыл бұрын

It'd be good to use a 160-degree fisheye lens, but it can be bad for number recognition because of the severe distortion. You can turn it by force on the basic lens. Please refer to this. electronics.stackexchange.com/a/458336

Congratulations on the demonstration, it was excellent. Would you recommend a complete product like the one in the video, however with a better image, perhaps a well-defined 720p or perhaps an average 1080p.

what would the wualiy be at around 10mm from the lens to the object ? - I'm designing a Vision based tactile sensor and the silcone needs to be close to the camera lens

@ThatProject

Жыл бұрын

10mm? This is too close. You can adjust the focal length by forcing the front part of the lens, but it seems difficult to get it to 10mm. I recommend you find other camera modules for your project.

So I bought a 2-package of the 160 degree with the longer cable. One works very well, the picture is so clear and the color is better than the little ones that came with the ESP32-CAM boards. BUT, sadly, the 2nd camera is trash. It just produced a square with random garbage flashing all over the place. I tested it on other boards just to confirm that it was the problem. It was. I then put it under the electronic microscope to see if by chance the cable had an issue. Nope. So then, I applied some heat with my SMD heat pen and for a quick moment, the picture came in, but was very distorted. So I figured, what the hell. I'll try to reflow it in case it was just a bad spot on the tiny pcb. Well... I applied the heat and POP!!! The camera sensor element literally popped off and when flying! ROFL The solder balls on the tiny pcb did seem to not be 100% right, but I can't find the element now to try to fix it. At least, by seeing this video, I saw that with patience, the little lens can be unscrewed. So I was able to unscrew that and put it onto the little cam that came with the boards. Now I have a wider view, which I prefer. So thanks for proving that the lens can be removed.

Hello! I am working on a project that needs a focal length of something between 5 and 10cm. What is the best lens for this?

A lens with a wide angle of more than 120 degrees may have a short focal length. You can also adjust the focal length by forcefully adjusting the base lens.

I think we cannot find any MCU which doesn't have a clock. Microcontrollers need a clock to ensure timing control. A clock signal is a particular type of signal that oscillates between a high and a low state and is used as a chronometer to coordinate actions of digital circuits. A clock signal is produced by a clock generator.
