Dam, my old antenna was powered over the coax. That’s probly what did it.

Cool, Thank you.

Thanks. Btw i found a DC auto transfer switch on amazon. https://a.co/d/a6pnd9B I assume i wire the car power to the “DC power source” so when it disappears it switches to “battery power” aka solar power. And the load terminal is wired to the DC in port on my bluetti

Good thing i asked the experts. Any i deas for a way to switch to solar power when i turn off the car? Like some form of diy relay switch

True.

Its running off a 5v usb brick. I am trying to alluminate the way to the bathroom for my mom late at night so she won’t trip or kick the household black cat. Also I ordered some PIR motion sensors to turn on the LED strip.

Its a product Safety standard. Here is a Wikipedia page. https://en.m.wikipedia.org/wiki/UL_(safety_organization)

I have dusted off this project, after shelving it for a bit. I have decided to embed a m8 nuts into the TPU solar panel mount. I want to see if i can embed a ASA printed nut into the tpu print. It should hold up to the elements ontop of my car. I would buy this, https://a.co/d/9Zx6j4k i cant spare to buy it due to being a broke college student living in his parrents house, LOL.

i want to log my car’s data over time.

Yeah the idea to 3d print solar panel mounts with printed threads is probly a bad idea.
