I vibe coded a driver to monitor and control the temperatures and fans in my Aoostar WTR PRO. (lemmy.world)

I run OmniOS on an Aoostar WTR PRO as my NAS and for most of my self hosting needs. After installing a new fan, I wanted to see if I could read and control the fan speed from the OS instead of just the BIOS. Using Claude chat, I got a working kernel driver that gives me fan speed, PWM control, temperature readings, and even (incorrect) voltage readings.

I wanted to share as an example of what's currently possible. I've even seen people vibe code ethernet drivers for freeBSD.

What do you all think of using LLMs to cobble together drivers like this?

First I asked it how to create a dump file. I hooked up ADB debugging to my phone, then used the scooter's app as normal, with the logging turned on in Android developer tools. It created a very long and complex dump file of hex that I could not understand.

However, then I had Claude get to work. I describe that in that I had opened the scooter's app, and turned it on, paused a few seconds, then turned it off and closed the app. It started attempting to mimic the commands through the computer's local bluetooth device, to get a successful response. Eventually, after something like 20 attempts it found a hidden clue that was basically a pattern that it had detected, and it was able to finally get an ACK from the scooter. Something I would have never been able to do. From there we have a plan on how to map out all of the other commands, but it was a huge win for the day.
