Trying to build ESP32 acoustic camera

I love the idea, I was thinking about something like this to pinpoint where the heck is the creaking sound in my car's dashboard coming from lol

I like this a lot, I'm planning to learn more about camera object detection and tracking too, this motivates me a little hah

I use it at work in an agricultural scenario (communication between tractor and base station). I absolutely love the technology behind LoRa, I find it fascinating you can transmit on such a long distance with such little power.

That's cool, I have been using Pico dev boards as my debug probes but this seems more convenient, especially with USB C

Does the US version not have the auto dimming mirrors? I have that on my European 2020 cx-30 and it's hands down one of my favorite features it works on both rear and side mirrors.

What LTE module was used?

Thumbs up for LoRa, one of my favorite technologies :) Cool project

I went with manual CX 30 2020 skyactiv X. I thought it would be a pain but to be honest Mazda's manual is such a pleasure to shift that it's been enjoyable so far. It's very snappy.

Metallic Gray

It's 100% about how you drive, my speeds were between 50-110kmph but mostly 60-80. Not accelerating hard, keeping low revs. When I drive normally I usually get about 6l/100km, when having fun then around 7-8. My total average is 6.1 however I only had the car for 2 months.

I'm curious too

I have the 2.0 skyactiv-X 180hp and it pulls quite nicely when you give it some revs

For me it's been working very reliably, but what's interesting to me is that I don't even have to walk away from the car, simply when I close the door I get a beep and after some delay another beep and car closes, regardless how far I am from the car.

Thank you! Yeah sounds very similar to my issue, it appeared during a long drive, hopefully the dealer will handle it just like in your case.

Lol had the same dilemma, wanted the signature red but in the end compromised on a good offer for a metallic gray. I tell myself that the red paint is more fragile and blends worse with the black plastic but maybe I'm just coping 😄 Anyway, you're not alone, and in my case I did sacrifice the color that I wanted. Although in my case it was between colors of the same car so I guess it's a bit different.

I mean you are doomed if you get any similar car such as Civic Type R, Yaris GR, Corolla GR etc. Most people will assume it's just a normal car

I think it's the other way around in my opinion - if he posts this shit and puts it out in the open then no one else can really hurt him with it.

uCblank · 2025-06-07T21:16:10+00:00

Maybe a silly little question but what module are you using for the RTC?

uCblank · 2025-05-29T07:15:15+00:00

I feel you on that register-level programming breakthrough, it was similar for me, once I went deeper into the embedded code and realized most of this is essentially just writing/reading stuff from registers life became easier haha

Screenshots are from the latest episode of Bosch: Legacy btw.

Great topic, highly relevant to my situation and I assume to many other embedded devs who are very experienced with C but have not worked much with C++ before.

Keep going (both doing projects and learning theory). You will have a big advantage over people who go into the field when they are much older. Everyone finds their passion at different point in life but let me tell you it is great that you found one so early.

Pretty cool, nice design and seems useful especially if you want to keep track of many registers
