What I want to do (rough idea)
Ultrasound seems really interesting. I would love to do something like the following.
Where to start?
I’ll start with assembling the board with ultrasonic array, and this video seems useful.
But I studied computer science and do not have electric engineering background. I have done some Arduino/Raspberry Pi projects but I did not understand how actually they worked to be honest. So, I decided to look over an introduction of electric engineering kind of stuff.
After looking through amazon, this book seems suitable for me. I’m gonna finish this book in a few weeks, while researching other resources, reading academic papers, etc. Sounds fun!
