What is a new thing, a new something that you have recently gotten into, or that you have been a long time participant in, that you find very entertaining and fun and time consuming and distracting?
What things would we need to purchase to get into that thing?
How did you get into that thing?
I got back into hobby electronics after life getting in my way for 20ish years. And wow things are a lot more available and out of the box than before.
Lately I’ve been getting into I²C peripherals. They’re pretty cheap too. Wanna build an X that does Y? Adafruit probably has some breakout board for you that does what you need. Hook it up to your platform of choice (Raspberry pi, arduino, etc etc) via four wires (well, 2… I just run power from a raspberry pi as well) and you’re good to go.
Optional: Combine it with a 3D printer to make chassis and mounting platforms.
I now have a raspberry pi that knows its absolute orientation, altitude, and position. I’m currently working on PWM input for receiving inputs from an RC radio I happened to have. After that it’s PWM output to control servos. I might build it into a semi autonomous RC plane/drone or similar. We’ll see where this project takes me.
