A LOT FOR THIS VIDEO!! I find so hard to understand things unless they are explained visually and from the very beginning and the underlying topics as well. I just get so excited because I wish everything was explained this way!! You make it so easy to understand and your voice is not boring at all! Thaaanks!

This is by far the best video on this topic I've seen so far. You did a great job of explaining this, AND you actually listed the parts! Great job!

I know this is an older video, but thanks for laying it out in a clear way, and you ordered the information just right that I could actually figure out the implications instead of it being spoon fed. I already figured out the full bridge rectifier into a capacitor store and regulator combo before it was even mentioned because of the clear and well ordered delivery. Thanks.

Honestly speaking, I used to not care about your videos earlier, but as time prolonged the quality of your videos raised exponentially with awesome illustrative graphics and lay man term explanations. Loved the videos really...keep up the awesome work and provide with more useful content...I recomment to make a video on PCB design and layout for RF PCB's(atleast try implementing this in your videos) . Thanks in advance.

great video. you make it way easier to understand how things work while at the same time allowing up to not be restricted on what we can make.

Would have been neat to see the difference in power loss between your home made charger VS the commercial one.

I love the very helpful instructions of winding the tank coil on the transmitter circuit appearing at 06:29 which "6 Turns ( 3 + 3) Center tap is in the Middle"

wow tysm! I wasn't expecting to get it yet after watching just one video and reading a few things online, but I understand it so much better now. I've never heard someone give such a good explanation of a semi-complex topic before :) --or at least, it didn't seem simple to me before haha. It was simple enough for anyone to follow, but you still went into the details to really understand what is going on, why, and how the variants interact.

You're an excellent teacher!! Thanks for sharing this
