Old Drone Camera Hacking

I found this camera module that used to be part of a cheap drone I bought close to 7 years ago. upon further looking, I noticed 4 empty pads and assumed they were debug pins, since it says "UART" somewhere on the middle of the module. I identified the power pins and soldered a USB cable to it. after plugging it to my computer, the module powered up but wouldn't appear on lsusb nor a serial terminal like coolterm. after a little bit of digging on the internet, I found a post mentioning a similar module to mine, but theirs appears to not have those 4 pins on the side. https://electronics.stackexchange.com/questions/490422/controlling-3-pin-pinhole-camera-from-drone-using-arduino one thing I could confirm was taking pictures and videos when hooking the yellow wire to power. ...

Arduino Mega 2560 Pro (Embed)

Being new to the Arduino world, I must say its been a roller coaster of a ride. I'm a flight simmer - specifically in X-Plane. I use a product called MobiFlight which is an application that communicates between X-Plane and my Arduino Mega 2560 Pro. What I'm finding that the Arduino IDE (with the Agent running) does not see the device. Its been challenging that the Mega 2560 Pro does not seem to be a popular device -- even for the Arduino app?
I have to admit, like I said, being new to the Arduino world, I'm still in the process of setting up and building my project which will contain 3 rotary encoders to start and will build from there with SPST switches.
Is there something I'm doing wrong with Arduino app that its not seeing the Arduino? withinn MobiFlight, I do a process call "Upload current firmware" to the board. This all works (directly to the board). Until I start to add devices (switches and encoders) to my board and startup MobiFlight from my sim computer, I cannot do anything further with the board until then. ...

Controlling A Video Overlay Device

Is it possible to have a Teensy 4.1 print to a Video Overlay Device? Here's an example of something I could use https://www.videologixinc.com/sdi-hdmi-video-overlay-devices/proteus-hd-video-overlay-device/

ESP32 with dual ethernet

Hi, I was wondering if it is possible to connect two ethernet ports to a esp32 or if I might run into problems there. I always only find connecting one W5550 to the ESP but I havent found anything about connecting two. I was also maybe thinking of getting a WT32-ETH01 and connecting an additional W5550 module to it .. would that be possible? Thx...

โš ๏ธ The ESP32 Cam isnt working

It worked at the shop when the shop owner checked it with compiling the code to it and after 5mins when i got home and i tried it by connecting to my laptop with a Micro USB cable the ESP wifi dosent showedup. And after i compile the example code by my self and check the Serial Monitor it shows

Motor & diode.

Okay, with this I'm struggling yo understand the current flow of this Back-Emf and this diode. As far as I get it; When the motor is off, (obviously there's back emf i know that) basically it says it let's current flow from the motors negative to the positive. How im not sure. Because ro me hsi diode seems the wrong wsy around for that....

Solar powered temperature-controlled fan help

Hope Iโ€™m not crossposting with this Iโ€™ve talked a bit in the main channel about this and I think itโ€™s to the point where Iโ€™m probably better off just making a thread on it cause I clog up too much space. An image is attached of my design but itโ€™s a w1209 temp relay controlling a pc fan. Both are powered from the same 12V battery (both rated for 12v btw). The fan runs when the w1209 detects a temperature above 70*F ...
