What a wonderful journey back to computing! The Raspberry Pi is such a perfect platform for rekindling that curiosity and hands-on exploration. There's something special about being able to physically tinker with hardware while learning programming. Your excitement really comes through in this post!
The picture of a little car kit loaded with a breadboard, a mountain of wires, and an added camera in the front was delightful. Now that's the hacker spirit! Thanks for the article, it's a joy to read.
Love to see the Pi getting some rather creative use! The most use I got out of one was as a health check endpoint for power in my garage which was holding frozen milk for my newborn, but the circuit kept tripping. Had another server email me if it couldn't reach the Pi for some reason. Just used some real simple Go code. It was not production but it worked. Not everything needs to change the world, maybe just make your day easier.
..and for his next trick, adding a servo is easy. Pigpio provides services underneath the operating system including square wave generators. Power the servo at 7.2 volts and drive the signal directly off a gpio pin at 5 volts!

I've built something like this using the ESP32-CAM if you want lower power usage. Although the real power usage is in the motors anyway.
It's awesome when it finally works and you can drive it around at a distance though!
This is car is so cute. I love it!
I have one of these:

Bad ideas are running through my brain right now.
How much does one of them go for?
You can get them for about 2000 euros in Europe. Variation in prices are mostly due to shipping from China.

using an entire computer to generate a PWM, hooray!
