I found these amazing wireless LEDs in Akihabara(aka Akiba) in Tokyo that light up wirelessly - with no wires or batteries! And I got them working on a standard phone wireless charger!

7:30 The second coil should work just like the LED - they are both powered through the EM field of the first coil. I think the reason for the second coil, is that it is able to provide a mutual inductance, which is strong enough to provide extra power to the LED. Also, I think the reason for the capacitors is to create an LC circuit so that the circuit resonates at a particular frequency, and u get max power transfer. I presume it's also there as a rectifier.

@tormodhag6824 3 жыл бұрын

The leds work by having the coil in series with the led, and since the LED is a diode the ac gets rectified. One of the capacitors are for smoothing and the other possibly forms an lc tank, which makes for a much more efficient resonant inductive coupling

@tormodhag6824 3 жыл бұрын

@Akash Gupta mutual inductance is when two coils interact, and a primary coil induces a emf in a secondary coil. This forms a transformer. For whatever reason the other coil is there for, it is not to «provide mutual inductance». The emf induced is also strongest in two parallel conductors, while the coils here is 90 degrees offset, which in turn means the magnetic fields does not induce much emf at all

@bigclivedotcom 5 жыл бұрын

The output of the coil would be AC I wonder if there were two LED chips in reverse parallel inside the original LED devices. It's also possible that if there was a capacitor on beard then it might have been in series to limit the current through the LED on each polarity change and prevent one LED from trying to sink too much current and affect the intensity of the others. You may find the field in front of a standard RFID card/fob reader also powers the LED in your coil.

I'm pretty sure the capacitor is used to make the circuit resonate to the frequency of the magnetic field. Thus, you can use a smaller coil, an still have high enough voltage to light up the LED

@MrRtkwe 5 жыл бұрын

Yeah the trick with wireless charging and power delivery is to match the inductance of the source and receive coils plus managing the resonance of the receive circuit. Doing that allows you to use a much smaller receiver coil and use less power or increase the distance you can transmit power over. In the crudest implementation the whole system is basically a tiny generator with the base station creating the changing magnetic field that induces a current in the receiver.

@aljaz55 5 жыл бұрын

I came to comments section just to see if someone spotted the obvious. Resonance is the key to keep the size down and efficiency up :-) Thus is why capacitors are needed, to form resonant circuit together with a coil. Bigger is not always better. Sometimes you have to work smart instead of hard.

OK, so in case I'm missing something here. The capacitors are to limit the voltage and eliminate high frequency noise from entering the chip. They act as a sort of buffer. As for the seemingly passive coil on the X-Base, I believe it works like a passive resonator or something of a feedback loop to activate the charging chip. The charger your friend was using needed the same thing. It just makes it turn on.

In the early 2000s, almost 20 years ago, I bought a wireless LED cellphone antenna. Antennas were often external and removable. My phone was a Motorola v60ti.

I had one of those too. They sold them in the mall kiosks.

Interesting video, keep up the good work man! 👍 You should have investigated and compared the maximum working range of the original stand with the Qi charger and tried to increase it.

At least a year and a half ago i told my partner i was going to try and make a completely contactless charger and she laughed at me so i moved onto something else. After seeing this i really wish i hadn't listened. Although this is not a charger i know i could have made something after watching you dude. Thank you dude for restoring the faith..respect, peace

@teuton8363 5 жыл бұрын

to maximise the output you want to tune the LC circuit to the qi charger frequency

I'm guessing that's what the capacitors are for.

Capacitors are there to increase the working range (resonant circuit), kinda like a small radio receiver. As an electronics hobbyist, I was stunned by your fascination about those LED's. But - can't say anything bad about it. Your shear desire to tinker with the stuff without knowing the theory, reminds me of myself when I was mucking around with electronics parts :) You are such a positive dude, Scotty, I love your attitude.

Hi from a Japan lifer !!! Love your videos. At the end of Akihabara, there is a massive model shop (I forget the name). You should have tried there.

Dude! Love this sort of fundamental electronics build project. Would be interesting for us if you shared some slides of the maths (in the video) to help us understand how you chose the coil size, capacitor value, etc. Noisebridge misses you! Come visit!

A couple of years later and Adafruit is now selling a base version of this for tinkering and developing. Came back to see if this is similar and it is very close. Just the coils are smaller.

@BlameItOnGreg 5 жыл бұрын

Would be great if you could do a video on resonant frequency matching the coils. I would love to learn more of how that works.

There is something about making your own coil to wirelessly light shit up that makes me feel good inside! Very cool channel sir! Thank you for showing me this, SUB.

@panzerdoc 5 жыл бұрын

the magic of electromagnetic induction. the electricity passing through the coil produces a magnetic field and that magnetic field induces an electrical current in the coil in the LED lighting it up. Pure magic.
