Raspberry Pi tutorials and project for makers

Let's make something together

Hi, I’m Peter.

I am an online educator and Maker, author of Maker Education Revolution, KiCad Like a Pro, and founder at Tech Explorations.

I create all the content on the Tech Explorations website. 

Why? Because, as I already mentioned, I'm an educator and a Maker, and I have a Mission.

My mission is to help people learn electronics, programming, printed circuit board design, and lots more. Most importantly, I want to help as many people as possible to enjoy their technology education adventures.

After a 15 year career as a University Lecturer, I decided to become a Maker, again. Like most of us, as a child, I was curious, and I learned how things worked by experimenting with them (usually, this meant taking them apart and hoping to not loose any screws as I was putting things back together). 

Growing up, I became an Engineer, only to loose my childish curiosity in the name of pursuing a career. 

I became a child again once I got my first Arduino. With it, I started creating thing, tinkering with components, testing ideas. Even though I was a "career educator", it was only now that I realised how wrong my last 15 years of education had been. I was partly responsible for destroying the creativity of thousands of students, just like mine had been destroyed in the name of being a "proper adult".

At Tech Explorations, my job is to learn and to create. I learn what I am curious about, and I create educational content. This content is the record of my learning.

I don't create this content to teach "students". I create it to help learners learn things that they want to learn. 

At the end of the day, we are all learners, and we learn from each other.

I sincerely hope that through the content I create at Tech Explorations, as many people as possible will be inspired to re-kindle their childhood curiosity, learn, and create amazing things.

Learning is social

The Internet has brought a revolution in publishing and learning. It is the biggest repository of knowledge that has ever existed, and it is getting exponentially bigger. For anything you want to learn, there's a good chance that someone has written a blog post or created a video about it.

Perfect! Well, not exactly. While there is a lot of great content out there, much of what is available on the Internet lacks quality, and most important, lacks the human connection.  

The best learning is social. When you communicate with others that have been where you are now, you learn faster and better. You have someone to fall back when you need help, or discuss an idea when you are stuck. 

At Tech Explorations, we support our students through our community tools because we know that this is the best way to learn and teach.

Helping is part of learning

Learning new skills and technologies is a journey into uncharted territory. It is much better if you have a map, and even better if you can "radio in" for help. 

At Tech Explorations, we have made a big investment in our communication tools to make sure that no student is left behind. We have three levels of Support: Community Discussion Forums for each course, lecture-level Questions and Answers tool, and a Help Desk. 

Our content is live and monitored by our team so that we can respond to student questions quickly. Speed is important because learning obstacles can have a devastating effect in our learning process, so we try our best to help our students smash through them.

Stay Calm And Keep Learning

The world and the Internet are extremely noisy places. Many "free" earning resources operate more like noisy open-air bazaars, with annoying distractions that aim to stop you from doing what you want to do (to learn something new) so that you can click on the next video (often about a cat doing a funny trick). 

The loss of concentration alone accumulates to many hundreds of hours of lost learning productivity per learner per year. 

Would you be able to learn how to program the Arduino in the food court of a shopping center? In a way, that's what many of us are doing.

At Tech Exploration, we have created a calm environment that is appropriate for immersive learning. Concentrate, turn off your mobile phone, start the lecture video, and follow on with the experiment. 

That's all. Nothing else should compete for your attention.

The Path Forward

In this page we have given you lots of free and quality learning content, opportunities for hands on experimentation, and even larger projects that you can use to consolidate your learning. All that in a calm, learner-friendly environment.

A question I get a lot is "What should I do next?"

People that have just learned a new skill, like how to make an LED blink or spin a motor, are often overwhelmed. They have just grasp something new, but are having a hard time figuring out what is next.

It is totally understandable, and I have been there myself. In fact, I feel like that every time I learn a new thing, isolated from its possibilities.

Think about this: you just learned how to spin a motor. How can you build a robot out of that? What is the process of going from a single working component, to a system that brings together many components, into a working gadget?

The best answer I can give to this question is this simple process, plus a lot of perseverance (you need it when you decide to pursue something important):

1. You need a project that excites you. This project gives you a goal, and even a path (although the path is not clear in the beginning). Think about what the project is about, and especially what it is supposed to do. This ("what is it supposed to do") is what gives you your project goal. You will need this for step 5 of this process.
2. You need to analyse your project and break it down to its components. A robot is made of motors, motor controllers and microcontrollers, sensors, software, and a frame to hold everything together. Figure out what are main components in your project.
3. Based on you analysis, figure out your level of knowledge in relation to the project components. You may have a good grasp of motors but lacking in sensor. 
4. Plan your prototyping process. This part of the process is critical, because you have to make several decision, that involve the hardware, software, and assembly of the gadget, but also the learning that you have to engage in in order to make this possible. You don't need to know everything before you begin, but you need to choose a place to begin. If you were to build a wheeled robot, for example, you could start with the wheel and motor assembly so that your robot can move, and leave the sensors for later. Why? Because you know how to use motors now. You can learn how to use sensors later. Like so many things in life, beginning is half of everything you do. The first iteration will give you the momentum and confidence you need to go for the second, third, until the last iteration.
5. Repeat until the project is complete. The iterative process of prototyping is your guide. Each iteration solves problems and creates new ones. The new problems usually demand that you learn something new. Go on, learn it, and come back to continue with the current iteration. The project is complete when you have achieved the goal that you set in step 1. But here's the catch: In prototyping, like in life, everything is fluid. Your original goal was based on early assumptions of what you wanted to achieve, before you had actually done any work towards that goal. In the process of working towards your goal, the goal changes! Be mindful of that, and know that it is Ok. Enjoy the process, and the achievement of the result.

This is the process that I follow with my projects, including my books and my courses. Over time, you will become better at picking projects and especially analysing them so that what you eventually create is very close to your original goal.

The only way to build up your project management and gadget building skills is to do it.

And we are here to help you 🙂
