I make videos explaining, and playing with technology of all sorts.
In 2016 I decided to start this CZcams channel. It was a nice way to combine my interest in technology, with my hobby of making films and videos. It started with mostly boring (and very specific) tutorials and explainer videos, in which I didn't even appear on camera. Over the years it evolved into what it is now, a channel with a wide variety of informative and entertaining videos about technology.
So here we are then, at the time of writing this about 7 years and more than 220 videos later. If you're a long time viewer, thank you very much for watching. Making videos surely is fun, but seeing that people enjoy them or find them helpful is what makes it great. If you're new here, nice to see you found my channel! I hope there's something on there you find interesting.

Why rubber shoes (or crocs) don't prevent electric shock
In this video, we take a look at the curious case of getting zapped while seeminly isolated from the ground. It turns out in some cases, electricity doesn't need a conductive path.

Excellent video and explanation! So much makes more sense now and somehow college classes failed to even cover this. I had always assumed birds avoided the really high voltage lines due to step potential but capacitive coupling makes much more sense. It also explains why folks working on transmission lines from helicopters attach bonding lines and why those attachments do generate quite powerful sparks.
Thanks uncle batany Kay leaya
very well presented.. cheers.
This is the best explanation I've seen. He also explains read direction and the speed adjustment. No one else does.
Awesome!!
So is lead acid the same chem. As gel lead acid?
Thank you.
Very nice thank you so much❤❤
Hi, I want to create my own SRM based on your videos (they are a great inspiration), but I have some questions. What is the purpose of D3, D2, and D1? Are these diodes preventing reverse current? What is the nominal power rating of the resistors before these diodes? How can I determine the current my motor will need? I want to use the DRV8300 to drive the MOSFETs. Is it a good choice, or do you recommend other MOSFET drivers? Are C1, C2, and C3 capacitors needed, or can I use one larger capacitor at the input?
@@kotrinio7868 C1, 2 and 3 are bootstrap capacitors to drive the top mosfets. They are charged through D1, 2 and 3. The drive voltage of the high side mosfets needs to be higher than the supply voltage, or thr mosfets will not turn on. Therefore, a capacitor (say C1) is charged up to the supply voltage (24v), then, when Q10 and Q6 are opened, C1 is disconnected from ground and instead connected to the source of the mosfet, pushing the voltage on the top of C1 above the supply voltage so that the mosfet can turn on. If diode D1 wasn't there, this wouldn't happen, the capacitor would immediately discharge. The need for a bootstrapping circuit like this could be eliminated by using P-mosfets for the high side instead.
Nicely presented in a very clear and concise manner. There are a couple of CZcams content creators who need to view this. There are some that have these concepts SO wrong and it is spreading false information.
Very simple yet effective, I like it! Great work my guy! I want to do something similar with a large array, but use photovoltaic switches in a "shadow" box to trigger the program, with a reset to a dedicated position at night. I really only want the panels moving every hour or so for a large array (10-12 panels)
cool
I was thinking it was headed towards an edger blade, then a mini mower of some sort.😅
Potentially it could work as a mower, if you sharpened it a bit more and run it in reverse haha
This is why we need Nuclear Fusion Power Plants. The ultimate in clean energy.
Dumb
dont forget that the energy that solar panels get from the sun is now absorbed by the earth instead of reflecting. this couses the earth to heat up even more.
up until the 80's people would literally put cooking oil on their skin to tan down at the beach, then we where told there was was an Ozone problem and to stay out of the sun, Ozone hole is now smaller and yet we still cant go out into the sun, must be the food they feed us.
You might need to brush up on entropy.
Tell me about it
There's a system that you can use to actually cool a house down better than any other system. What you do is you build a concrete bunker that is about the size of a A/C unit. Make sure that it is sealed off to the outside air, but has ducting to bring air from the house into the area and feed it back up to the house. You have water drip over the concrete slabs, which will cool the slabs down, and cool the air inside the concrete bunker. As you pull air from the house into the bunker, the bunker will cool the air, and put it in the house, as the house heats it up, it is pulled back down into the bunker to be cooled. The only thing you need would be a hose system and a fan. Problem would be solved better. Because the problem with modern day A/C units has nothing to do with the electricity and the release of CO2 into the atmosphere if you are running off a Nuclear power plant. The problem is that in order for your A/C unit to work, the condenser has to release heat from unit outside the house in order to release cool air inside your house. It's why if you want to cool your house down, opening up your fridge and freezer will actually cause your house to heat up not cool down. Sure you can get cool air at the point of where it comes into the fridge, but that compressor in the back will actually release more heat than the fridge reduces.
What do you do with the OLD solar panels and HOW many ppl use Air Conditioners over there.
Luckily, there's zero fucking evidence that carbon emissions create a rise in temperature.
He’s saying what we were all thinking
The problem is not carbon, it's greenhouse effect, which make air conditioning even worse than said, because of the amount of steam released to cool the air, whatever the energy you use to power the AC. Get your facts straight...
But where does the heat go
Usually outdoors
Honey, do you know what a paradox is? This ain't it.
Are you dumb honey? He's providing a solution to the paradox thanks to the introduction of solar
There are multiple kinds of paradox. Check jan misali's video on the subject.
the paradox: AC is meant to cool, yet it heats
I don't see a paradox.. I see a simple positive feedback loop. The cooling creates conditions which need more cooling. A paradox is an intractable logical contradiction.. 'This statement is a lie'. .. etc
@@AKIOTV that's not a paradox tha'ts laws of physics.
You still create more heat than "cold" with the AC... So by turning the AC on you heat up the planet
My brain hurts from reading this.
That's right, that's why a room doesn't get any cooler if you leave the door of the refrigerator open.
If the energy used by the AC is solar power, the waste heat it produces is solar energy that would otherwise have heated up the earth's surface directly. The net result is the same.
@@AKIOTV But the AC components get warm during operation, so they heat more than they cool. In a refrigerator, the ratio is 85:15 heating:cooling. It will be similar for an AC.
@@ghostdog5198 yes, but ultimately all the additionl heat that the AC produces on top of the heat it removes from the building is energy that comes from the power source. (the solar panels)
I don't care about stabilizing thee power net. But I care about health and costs. The best way to do what was described is to produce and use the power yourself. Use as much as you can, and sell the rest. Use as few power as you can while your solar panels don't produce power. Because doing different is throwing money at companies that don't care about you or the world.
A large portion of this issue isn't the energy being used by the AC systems but the chemicals that are used for AC and refrigeration such r-12 and r-134a.
Correct. Carbon emissions from the energy used is less dangerous to the environment than the refrigerants that eventually escape into the atmosphere. Thomas Midgley (the man who created cfc's for use in refrigerators) may have killed the most people in history and destroyed the ozone. Bans on cfc's have caused the ozone to start repairing itself but will take another 30 years to return to pre refrigeration levels. He also created an additive to help reduce the sulfur smell in gasoline sold to the public as safe. The additive was named ethyl and was actually lead. Estimates suggest lead from gasoline still causes over 1/4 million deaths from heart disease each year.
most of the world doesent ahve conditions that are clear enough for optimal solar use
There's a simple solution they just make the energy so damn expensive that you can't afford to run the air conditioner anymore that's what's going on in America how about over in Europe
Depending on your electricity contract, even negative prices are possible. There are people who get paid to use power during days with lots of sun or wind. But yes of course on average energy prices have generally increased, mainly because of natural gas and oil prices going up.
When I read "prop" everything but the propeller came to my mind 😅
Justin Bieber?
Even pop stars need a hobby, this channel's mine
great video and hard work .if u add dc to dc converter as boost one to 320v dc so u can regulate pwm to control the power by measuring the output power that deliveried to grid .the dc to dc input can vary as solar or wind input change so pwm can comensatet that to what the adjusted max power. u can buy one for example input rate 12v, to 35v after that thake the important components like ferrite trans and mosfet but before check its frequency then reprogram arduino to deliver the sam freq to guarantee the core not saturate.by adding some probe current and volte of output u can produce your pwm duty cycle .
On of best explanations about this discussion in CZcams (i ever seen!)
Shall we build solar energy plants correctly, it would be super beneficial
Isn't "Stabilize the power grid" a bit of an over-simplification due to most solar Electric meters being "dumb" even where the grid is "smart"? I understand the fact that using PV to power Air conditioning reduces demand from the grid but it's not all that easy, especially with how some MPPT work.
Well of course the power grid is kept perfectly stable nonetheless (or it would fail), but introducing extra load during the day makes this easier to do for grid operators. Oh and yes it is an oversimplification, normally I like to make 20+ min videos going into the details and nuances, but unfortunately these shorts are limited to one minute haha.
@@AKIOTV Absolutely, not trying to being negative or criticize you. Your full videos are great. Love the series on SRM and you explain it
How does the oscillating frequency from the transmitting coil affect the function of the device? Would a frequency above human audio range be better, with the receive signal being fed through a frequency divider to enable the operator to hear?
It depends on the range required/the size of the objects etc what's best. Normally the lowest frequency they operate at is about 10kHz, which you could technically hear, but it's a very sharp, annoying high pitched whine, so usually, even at lower (audible) frequencies, the tone the operator hears is not the carrier signal itself but indeed something derived from it.
OMG! this is the best explanation on the web. Thank so much I've been surfing the web for hours for an explanation and came across your video and finally I understand!
awelsome
YOU HAVE SUMMONED ME
Good Idea
does the mppt reduce the life cycles of batteries?
no
@@AKIOTV thanks for very quick reply sir.
thanks,Mindblowing
😅poʻrn
Porn
best ever explanation 👌
Important detail: there's something I did not explain right. When a metal object approaches the transmitter, it does produce an opposing field, *however* the transmitter coil will experience an increase in current that compensates for this, so that the net field remains the same. Just like in a transformer: drawing more current on the output also causes more current draw on the input. For this reason, if your receicer coil was identical to your transmitter coil, and placed exactly on top of it, it would see no change in the field. The key then, is that the receiver coil is shaped differently, has a different size, or is placed in a different location. Although the metal object doesn't change the net field through the primary, it does change the field locally. (in other words, the shape of the magnetic field). Therefore the pickup coil needs a shift in position, a different size or a different shape. I did not go into the importance of the coil geometry/placement well enough in this video, and plan to do this in a revisit later on. Thank you for watching!
Thanks man !
Thanks man !
Could we have some maths with it, an equivalent circuit for example?
