Welcome to Wireless Power to the People, the course that brings wireless power to the masses. In this course you're going to learn the basics of the different types of wireless power being researched and developed today. Spoiler alert: Some of them work a lot better than others!
You're going to start out by learning the basics of magnetic induction. Then I will show you the power of resonance. Soon you're going to learn how to build a simple wireless powered LED. Things are really going to get interesting when you learn how to increase the power and range of the system, and wirelessly power LEDs, motors, fans and more up to 30cm away! And for the final project we're going to upgrade USB powered devices to be charged with wireless power.
If you have ever wondered how wireless charging works, this course is for you.
In the media we've seen countless stories of wireless charging using radio waves, vibration and more. Yet we still haven't seen these devices appearing in our homes. Millions of dollars in venture capital have been burned because investors did not fundamentally understand the various technologies used in wireless power.
In this course I'm going to cut through all the hype and explain the different types of wireless power being researched today... the pros and cons of each, which ones are viable, which ones are not, and why. Best of all, you will not need a PhD in physics to understand what is going on. Math in this course will be kept to a minimum, and the focus will be on developing an intuitive, visual understanding of the concepts involved.
During the course I am going to be showing you some wireless charging experiments that will require a power supply, an oscilloscope, and a few electronic components. If you don't have these things and you don't feel comfortable building circuits, don't worry. You'll still have a ton of fun just watching the demonstrations and you'll be able to understand the magic behind wireless power. By the end of the course you will know how to wirelessly power any electronic device up to 4 watts! The basic principles taught in this course will scale to higher power levels if you choose to continue work in this field.
If you've ever wondered how a Samsung phone charges, this course is for you. If you have ever wondered how iPhone X and Apple Watch charging works, this course is for you. If you are a student or junior engineer who is looking to get up to speed on practical solutions to wireless power problems this course is for you. And if you're someone who is thinking of investing money in a crowdfunded wireless power project, do not spend a dime until you have watched this course!
Thank you for watching, and I hope to be teaching you soon!

After getting my BSc in Electrical & Computer Engineering I started my own electronics design and manufacturing company. We focused on power electronics, sensors and robotics.
I have designed and sold multiple products that have sold by the thousands. I have also done private contract designs used by high profile C-level executives, and have been awarded a patent. To date, I have 13 years of professional electronics design and manufacturing experience.
My love of photography lead me into video production and I have produced 67 tutorial videos totaling over 45 million views. They are used by institutions including the University of Purdue, the University of British Columbia, the United States Military (defensive electronic warfare) and even a nuclear power plant! My work has been featured on Hackaday, Slashdot, Engadget and other high profile blogs.
I was lucky enough to have a father who subsidized my education and as a result I have a great life. I want to help others have the same.
