10 things you can build with electronics

protostack-board“What can you build with electronics?”, she asked me…

“Anything!” I said.

She looked at me with a blank stare. Apparently that was not a satisfying reply.

This happened to me a few days ago.

Sometimes I get too deep into electronics that I forget “normal” people don’t necessarily understand what you can do with electronics.


Here is ten things you can build with electronics from the top of my head (drum roll please):

  1. A blinking light
  2. Two blinking lights
  3. Three blink…. Just kidding. But lights that dance to the music
  4. A little device that automatically sends out your business card over bluetooth to anyone who is in the nearby (yes I made this)
  5. A WiFi-connected plant pot that tells you when you need to water your plants
  6. A robot that can fetch you beers
  7. A quadcopter (also called a drone)
  8. An automatic cat door
  9. A coffee machine
  10. A pinball game

So that’s ten things. It usually helps to do a brainstorm like this when you are looking for a new idea.

And now I have some more things to tell the girl if she asks me again.

To start building electronics, I recommend my eBook «Getting Started With Electronics», which you can get here:

  1. I have a final project coming up for my electricity/electronics class and I’m having problems figuring out what I should make. The project has to be something that I can make from scratch but nothing that will take more than 2 weeks to build. Also it needs to be able to function directly on a pcb such as the brain game. Any ideas?
