Comma.ai

I saw the schematics on discord, does anyone have a picture of the finished product?

I bought my first comma 3 back in 2021, this unit was replaced on warranty in 2022, yesterday my comma 3 died. No more repair support for comma3 from comma ai., only trade in options. Reading reddit seems to be very common case. Average life time of comma device is 4 years. They offer after warranty repair of comma 3X for the fix price of $500.

I replaced my C3 with a C3X after it died. I've heard that there is a fuse to check. There is a wiki on it. But I didn't know it until after I did the trade in.

Not sure, if it was a fuse. Blue LED on backside was still blinking, I believe it was something else. People on reddit are saying some cell phone repair shops were able to fix for $200. Price for afte warranty repair by comma.ai raised 5 times from comma 3 to comma 3X.

There's more than one fuse. And that's probably what the cell phone shop fixed.

Seems like no fuse inside:
