Who Runs Random Nerd Tutorials?

Behind Random Nerd Tutorials is Rui Santos and Sara Santos. We both live in Porto, Portugal, and we have known each other since 2009. Keep reading to learn more about us.

Hi! I’m Rui Santos, the founder of the Random Nerd Tutorials blog. I have a master’s degree in Electrical and Computer Engineering from FEUP. I’m the author of “BeagleBone For Dummies”, and Technical reviewer of the book “Raspberry Pi For Kids For Dummies”.  I recently wrote a book with Sara Santos for the NoStarchPress publisher about projects with the Raspberry Pi: “20 Easy Raspberry Pi Projects: Toys, Tools, Gadgets, and More!“ If you want to know how I started the Random Nerd Tutorials blog, read the “How RNT Started?” section below.

Hi! I’m Sara Santos! I started working at Random Nerd Tutorials back in 2015 as a hobby: I helped Rui with some simple tasks when he had a lot of work to do. Back then, I knew nothing about electronics, programming, Arduino, etc… Over time I started learning everything I could about those subjects and I just loved it! At first, I helped Rui once a week on Saturdays, but then, I started working on the RNT blog alongside him, almost every day!

In 2016 I finished my Master’s degree in Bioengineering from FEUP, and at the end of 2016, I started working in a Water Treatment Company. At the same time, Rui and I accepted an invitation from NoStarchPress to write a book about Raspberry Pi (so, I had a lot of work to do). In August 2017, I decided to quit my job to dedicate myself 100% to the Random Nerd Tutorials blog. Currently, I work full-time at Random Nerd Tutorials as a Content Editor and I love what I do!

How RNT Started?

Rui Santos started the Random Nerd Tutorials blog in 2013 to share his Arduino electronics projects. Back then, he was studying Electrical and Computer Engineering, and a friend told him about the Arduino board. He was amazed with what his friend said about the board, and immediately ordered an Arduino starter kit to experiment.

Then, he thought it would be a good idea to create a blog to share his Arduino projects with others and give them instructions on how to replicate the projects themselves. At that time, there wasn’t much information about the Arduino, and his blog posts started receiving a considerable amount of views and good feedback. This encouraged him to keep posting new projects and tutorials.

Over time, he added content not only about Arduino, but also about other subjects like Raspberry Pi, ESP8266, Node-RED, ESP32,and Home Automation.

Today, Random Nerd Tutorials has more than 600 free blog posts, videos, and courses that anyone can follow to start making their own electronics projects. Random Nerd Tutorials has been featured in…

Maker Advisor

We launched Maker Advisor website in October 2017. Why did we create Maker Advisor? We noticed that our followers often had trouble finding where to buy the parts, and where to find the best price. So, we created a page called Maker Advisor Tools to help electronics hobbyists and makers find the best tools at the best price. We also post buying guides, as well as reviews on tools, gadgets and development boards that we think you may like.

At the moment, all Random Nerd Tutorials projects contain links to the Maker Advisor price comparison pages, so that you know exactly where to get your parts from. By getting your parts using our affiliate links you are supporting our work.

We don’t write custom code for you. We can’t write entire programs for you. We receive many emails per day requesting complete tutorials. There’s not enough time in the day to do that. We make an effort to make our code as general and documented as possible so that you can easily modify the code yourself. However, if you have any questions feel free to ask by leaving a comment on the project page. We may give you quick tips on how to modify your code or redirect you to a specific project tutorial.
