Definitely replicating that motor with PWM on the high side.

Your explanation is way too technical. I give your video a thumbs down .

well done !

Excellent, thanks.... I'll get connecting my 12v lead acid batteries in parallel.....

Thanks dude, that was an excellent explanation of how memory dumps work.

and ill tell you why.. that yagi has rf blockage because your boom is too wide

Is it ok to look at these towers

best simple explanation so far 👍

Are there parts in the newer power supply that weren't available back in the days, or were they too expensive?

Maybe it's possible to rapidly charge a supercapacitor with a large generator and then use the stored energy to charge the battery.

Had to watch this 6 times b4 I finished it, I kept falling asleep

You can reduce the time to look at a certain angle. In my view it's high so it may be wasting all energy in looking for sun.

I am not a native english speaker but I know you are a excelent comunicator

Imagine the info structure cost $50k for car and $50 to $150 k for each charger

hi, you should have try to moove the reciever coil so it bearly pick the signal, you would have a much better sensitivity

Well done Interesting and informative Thanks

It should also find its ultimate tilt angle 😀Plus, what would be the difference of Wh yield when it’s being oriented to the south with a tilt angle of 37°?

So far it looks it uses more than produces 😂

The seedy dude. How does cd work.

Norty putting magnets on the rotor! Must do the inductive version, minimised hardware and physical size, maximised control... Then you can sell the PCB! Home made pancakes motors are awesome for tiny and low power PTZ control of covert CCTV cameras, for example, so low-speed uses are interesting, especially if you create a design using an axial absolute position encoder, high precision servos etc... Turbine generator projects also interesting. I hope you keep this up long enough to do all the things!!!

I just need to say thank you for the amazing video. Well explained!

The question is: Is it harmful for the solar panels to be exposed to higher heat if turned off for prolonged time.

Very good video. Straight to the point in a very clear and concise way.

Consider savings for public charging sites: pad in the ground is more robust and is faster/cheaper to install and maintain than a wired connector. Then there are autonomous vehicles. You don't even need level-5 autonomy -- just auto-park in a private fleet lot, for example.

this is a surprisingly good video! +1 interaction, if i see you again in my feed i just might sub!

this is such an amazing and brilliant video. I have a few questions about this too. with these motors would they run more efficiently if they were dirven with a sinusoidal voltage rather than a constant pwm? with permanent magnet motors they benefit form sinusoidal voltage input but since this has no permanent magnets would it? it still seems so since the primary reason for sine wave is motor geometry and angular velocity but would you know? and i think its really awesome how you release all your code and diagrams, i could never design something like this myself but having some designs to copy, learn from, and tinker with is great. and would it be better to do fast switching on the high side mosfet for the same reason that the diodes are necessary? if you switch the mosfet that feeds the phase quickly then it doesnt experience the high voltage from inductance. im also a novist everything I sad here could be wrong. its a very good video though.

Very cool. It's such a fascinatingly simple motor design. I'd be interested in seeing if it can be run at low RPM in conjunction with more accurate feedback. A multi-axis hall sensor perhaps, or a quadrature encoder. Or maybe holding arbitrary fixed positions, micro-step stepper-driver style. Regarding balancing, you might check out the setups to balance rc props for balancing the rotor. It's basically a levelled stand with two pair of low-resistance steel wheels for the shaft to run between. A similar arrangement of four cheap skate bearings with the shields removed might work as well? Although the shaft would probably be needed to be straitened out first. Or if you have a scope, there is a video on dynamically balancing a motor with a small speaker as a contact vibration sensor, that seems it could be applicable? Rather than referring it to a BLDC, since that seems ambiguous, perhaps call them PMSM, permanent magnet synchronous motor. That seems to be an accepted terminology. Also, if I understand correctly, the SRM stator and physical arrangement of poles are similar to a PMSM, and the relative magnetization forces between rotor and stator would seem to be functionally identical between them. Therefore the difference between SRM and PMSM is in how the process of inductively magnetizing the rotor for smooth rotation requires very different driver voltage waveform in the stators? Just to clarify.

Great video. Explains why wireless car charging *is* feasible. Now the question becomes "is it worth it." Well, I think it is if you car is a self-driving robo-taxi.

I'm simply lazy enough to do it without a good reason.

What a great video, thank you! I was curious about this actually. I personally like automating minor annoyances such as finding your keys to unlock your front door every time you leave the house and come back. I would pay for these electronics personally, would be even cooler to do a diy installation of this concept beneath your garage floor so everything is hidden and sleek. Now I’m hearing that electric cars are worse for the environment just because of the lithium mining. I’m not sure how all those numbers compare to ICE’s, but I think the bigger problem is getting that sodium battery technology going. A big draw to electric vehicles (just my opinion) is that your main gas station is at home, unless you go on long trips very often. So I don’t think getting more charging stations is too much of a major issue (again just my opinion). If anyone has any other thoughts and reasoning, let me know.

It's another long one haha. Hope you enjoy watching it :) Some more info: - The Witricity system is based on SAE J2954. This standard contains more design detail for these coils and possible circuitry. The document is however, (of course), behind a paywall that exceeds my usual budget for videos, so I haven't considered these specs. Feel free (if you want to spend a couple 100 dollars) to compare my example coil to the actual designs in the standard, but if anything my assumptions were probably in favour of the WPT system, so it wouldn't really change the conclusion much.

But doesnt a wine glass have multiple natural frequencies depending how you hit the glass?

Sorry I have a question, I need to kee my truck battery charged, but in that truck I also have a tennis ball machine that has a battery if different size but both have the sane chemistry. Would this method work to keep not betteries charged with one solar panel Thank you

Look up company called Edison motors in BC Canada. They are doing commercial logging trucks trucks that are diesel electric and they’re also going to be getting into work trucks 1 ton and bigger.

sounds like trash

Great bike analogy!

Good stuff, man! Well done. Thanks!

Your so cute

best thing on mppt

Perfect, great analogy with the gears too. Thank you

What a horrible explanation. 1. You demonstrated a de-tuning effect of a coil near a metal object. Not how modern two coil detectors work. 2. You should have a second pobe on the TX coil to trigger the oscilloscope trace for the timing of the rx coil. 3. This would allow you to null the rx coil so that the signal strength is near zero. 4. Place metal near the coils and you could witness the signal strength and the phase change on the rx coil. 5. This would demonstrate the ability to detect size and depth on a metal as well as its conductivity for a generalized identification of metal and size/depth. keep learning.

Guess I’m not the only one who random had a crisis about how tf a disc works 😂

Since the transformer casing is connected to the nuts, when the whole thing is under tension and sitting on a damp concrete floor, it might kill you. If you put it on a conductive table you're leaning against, it will easily kill you. This is really playing with death and just a horrible design. Thumbs down and reported.

Great video!! Love the voice 💯🤜🤛

The risk of blowing the phone outweighs the benefits

Let's say you are finding this token device, and it takes some good amount of time , AND THEN we press the button for it to give us an 8 digit code. how will that be sync since the click was later on then the servers'

So well explained ❤ I have a 1080 by 1920 smartphone display

After 2 hours of looking through laser printer videos I finally found one that is actually useful
