Want to buy Rui a coffee?

Random Nerd Tutorials is a free online resource with electronics projects, tutorials and reviews. Please consider donating to Random Nerd Tutorials, so Rui can keep creating new projects! You can also explore our most popular projects here.

You can download some eBooks for free, but some of them are paid. If you enjoy my work you can also donate a few dollars to buy me some coffee for my next projects.

I actually drink a lot of coffee to be awake until very late to write posts and edit videos. I also need to buy new parts, measuring tools, hosting expenses, recording equipment, etc..
