I have a 3d printer in my car powered by a bluetti eb3a. The bluetti is charged by the 12v outlet in my car while driving. I have a 24v solar panel i want to mount to the roof of the car. My bluetti has only one dc 7909 input. So got a a Y splitter to combine power from the car and panel. But when plug it into the car outlet that turns off when i turn off the car, the solar panel turns on the stereo. Thats not the case with the outlets that are always on. I am worried that i will danage the car electrical system from a 24v solar panel flowing electricity back into the car?

I am working on a WLED project, using a esp32 in a 3d printed enclosere. But my dad says that i can't install it because it is not UL listed. He is worried if the house burns down, the insurance company won't insure it due to diy electronics possibly starting a fire. What am i to do, i am not developing a project to sell?

Does anyone know a way to connect a car odb2 port directly to home assisant without the torque pro app?

My ender 3 v2 extruder is crushing the filament and snaps thus the printer fails to print. I have adjusted the extruder tension, nothing has changed. I also upgraded to a 0.6 hardend steel nozzle and I checked if it was the nozzles temperature, that made no difference.

i was setting up postmaster on Linux Mint, and i saw that a lot of UDP requests were blocked from one local IP address. I found out the IP belonged to my parents Samsung smart TV. i loaded up wireshark and found out it is sending UDP requests with different port numbers per request. any ideas what is going on, and how i can stop it.
