What you may be taught

  • Study the numerous wi-fi energy strategies in analysis and growth at this time (together with a number of which are scams!)
  • Study the execs and cons of all the completely different wi-fi energy strategies and the ONE expertise mature sufficient for mainstream shopper use
  • Perceive electromagnetic induction
  • Intuitively perceive resonance and LC resonant circuits
  • Perceive inductive coupling and resonant energy switch
  • Construct a circuit that may wirelessly energy a small fan
  • Construct a wi-fi energy circuit that may energy an LED 15cm away
  • Construct a wi-fi energy circuit that may energy LEDs, electrical motors and extra 30cm away
  • Perceive “the pores and skin impact” and the way to mitigate it
  • Perceive the foremost parts of recent industrial wi-fi charging techniques (with emphasis on Qi)
  • Perceive how knowledge communication works in Qi wi-fi energy techniques
  • Use off the shelf {hardware} to wirelessly cost telephones, Ps controllers and different USB gadgets
  • Use off the shelf {hardware} to wirelessly energy any digital machine up to 4 watts


  • Fundamental information of electrical energy, resistors, capacitors, inductors, transistors, breadboards
  • Fundamental information of schematic studying, perform mills and oscilloscopes if you would like to recreate a few of the experiments your self

Welcome to Wireless Power to the People, the course that brings wi-fi energy to the plenty. On this course you are going to be taught the fundamentals of the various kinds of wi-fi energy being researched and developed at this time. Spoiler alert: A few of them work so much higher than others!

You are going to begin out by studying the fundamentals of magnetic induction. Then I’ll present you the energy of resonance. Quickly you are going to learn the way to construct a easy wi-fi powered LED. Issues are actually going to get attention-grabbing if you learn the way to improve the energy and vary of the system, and wirelessly energy LEDs, motors, followers and extra up to 30cm away! And for the closing mission we’re going to improve USB powered gadgets to be charged with wi-fi energy.

In case you have ever puzzled how wi-fi charging works, this course is for you.

In the media we have seen numerous tales of wi-fi charging utilizing radio waves, vibration and extra. But we nonetheless have not seen these gadgets showing in our houses. Hundreds of thousands of {dollars} in enterprise capital have been burned as a result of buyers didn’t essentially perceive the numerous applied sciences utilized in wi-fi energy. 

On this course I am going to reduce by means of all the hype and clarify the various kinds of wi-fi energy being researched at this time… the execs and cons of every, which of them are viable, which of them usually are notand why. Better of all, you’ll not want a PhD in physics to perceive what’s going on. Math on this course shall be saved to a minimal, and the focus shall be on growing an intuitive, visible understanding of the ideas concerned.

Throughout the course I’m going to be exhibiting you some wi-fi charging experiments that may require an influence provide, an oscilloscope, and some digital parts. If you do not have these items and you do not really feel snug constructing circuits, don’t be concerned. You will nonetheless have a ton of enjoyable simply watching the demonstrations and you will be in a position to perceive the magic behind wi-fi energy. By the finish of the course you’ll know the way to wirelessly energy any digital machine up to 4 watts! The fundamental rules taught on this course will scale to larger energy ranges should you select to proceed work on this area.

When you’ve ever puzzled how a Samsung telephone costs, this course is for you. In case you have ever puzzled how iPhone X and Apple Watch charging works, this course is for you. If you’re a pupil or junior engineer who’s trying to rise up to velocity on sensible options to wi-fi energy issues this course is for you. And should you’re somebody who’s pondering of investing cash in a crowdfunded wi-fi energy mission, don’t spend a dime till you could have watched this course!

Thanks for watching, and I hope to be educating you quickly!
