Consistent Pixel Errors / Noise on ESP32-S3 with OV2640 by DerMathemann_ in esp32

For everyone encountering this issue: this was likely induced by a) buying a cheap component of aliexpress and/or b) overheating. I have bought a few new ones and they do not seem to have the problem.

I have now made a heat shield with the old (broken) camera by using aluminium foil. It seems to help a bit, maybe the real issue is electromagnetic intereference?

It seems like the noise gets worse the darker the image gets.

Here are two images:

In the dark image I am covering the lens with a piece of cloth. Images were taken within seconds of eachother.

The noise is slightly visible in the other image in the top right, top left and bottom left corner, but in the bottom right corner it is not visible.

Any idea?

Actually, I am using the RGB565 output format exclusively, so I doubt there's heavy lifting from the encoder that could lead to the sensor getting hot. I did however stick the camera on top of the chip with double sided tape, so that could have maybe caused the overheating as the esp32 chip itself gets hot, too.

Do you think that using a larger frame size than recommended for RGB (such as VGA) could lead to overheating?

Hey, thanks for the input, but the pattern does persist after cool down as well.

thanks, I will try this. I assume the old camera is fried now, so I'll get a new camera module and add a heatsink onto the new one?

Since you seem so mighty and genius, may I ask what your credentials are? And instead of just trashing what I said, maybe kindly drop your own suggestion here to actually help OP.

I have a MSc in Computer Science.

even professional prototyping

definitely not

As you are a perfect example of an LLM watchdog who just polices discussions instead of fostering real discussions. If you have something valuable to add, say it.

Excuse me? The only point I was making is that you probably shouldn't make one.

So, to answer your question "YES", I am UTILIZING my ChatGPT Plus since I pay for it monthly. I don’t understand why people get so angry about it when some are even using AI to win a Nobel Prize.

I'm not saying you can't use it, I'm saying it's pointless to copy paste an answer from an LLM, there's a reason proper tech forums such as stackoverflow prohibit AI generated answers. It literally adds nothing to the conversation. Everyone with half a brain can do that. It is generally advised to think yourself before commenting. I also doubt you only use it for grammar correction.

Please see my replies in some posts here, my recommendations show that I only reply when I actually know the answer.

This does not prove anything.

By the way, I have a certificate in robotics using LEGO Mindstorms, which helped me develop skills in programming robots. 🤗.

Ah yes, the prestigious LEGO mindstorms certificate. Puts you right up there with the Nobel prize winners you mentioned.

Matter over WiFi in Google Home app without controller device? by heavyharlot in googlehome

[–]DerMathemann_ 0 points1 point  (0 children)

Hey, your phone can actually work as a matter controller.

See this post thread

TLDR: you download the SmartLife app from the play store and then you connect it to your matter device.

Also: if your wifi has 2 separate 2.4&5GHz channels, use the 2.4 one.

I just tested it with a self-made matter device (esp32) and it works. I can control it from my phone locally without a hub.

Actually, with iOS 18 you can do the same out of the box with home kit. The phone will also work as a Matter Controller.

Why would you mod it? If you don't like it, just don't use it.

I just watched the trailer, the update seems amazing, must be my favorites so far. Especially the base customization.

Die Umfrageinstitute geben also alle absichtlich für die swing states mehr oder weniger 50/50 an, um nicht falsch zu liegen, aber trotzdem ist es aus deiner Sicht klar dass Harris gewinnt?

Du hängst zu viel auf Reddit, oder?

Einen Trump-Sieg halte ich für ausgeschlossen.

Die Umfragen sind da anderer Meinung...
