I understand that these guys don't really know the technical side of things, but they utterly ruined the PCB and the whole vehicle as well. Yes I give them the benefit of the doubt that they don't know the proper terms, but hearing "The motherboard, the chipboard , all kinds of technology." cracks me up! It's like please just open them up with a screwdriver and actually go into depth. I mean they do call themselves what's inside, not let's cut it open.
Not saying it's not fun or informative(ish) to what they are doing, as it can lead to better thing in those kids lives. But just the fact it's more of a hackjob. What's your take guys?

Wow, that was a major hack job! Wouldn't it have been simpler to just remove the screws holding the circuit board to the chassis rather than beating the hell out of it and prying it off?!? I saw at least two of the screws still in the board with the broken off mounting bosses in the close ups later on. And the 'charger' looked a lot like a battery compartment to me, but what do I know? Sheesh.

I think that is just their thing, I don't think they take stuff apart in a reversible way...

Just another of those weird YT channels that get lots of traffic for some reason.

Cool RC Car, kids. Want to bring it to the White House? We should inspire more kids like you to like science. It's what makes America great.

He has a screwdriver and instead of using it to undo the screws, he uses it to pry it open. :palm:
"It is definitely rear wheel operated" :palm: :palm: :palm:

Not a teardown, but very much cringe worthy:

Seems to be the new formula for success on YT - vapid content heavily seasoned with idiocy and destruction = high # of views
-
I think it's great that they're pulling it apart and having a look. There are many ways it could be done and infinitely different levels of understanding.
I only wish schools did this in front of students.

Think of how much _more_ the kids could have learned by disassembling the car in such a way so that it could be _reassembled_ into a still-working... or even _better working_ condition. How much more fun they could have had by actually improving the car so it would be a winner instead of a loser.
What did they learn from that destructive teardown? That you can use a screwdriver as a prybar? :palm:
It's a sad commentary on the current state of education that such a purely destructive video gets so many views, when one that might actually _teach something useful_ is ignored because it's "less fun" or something.
-
**sigh.** :palm:
-
Sadly that channel is big enough to a point where they just don't care if they screw stuff up because they will still be making profit off of it, and those kids will end up spoiled as all heck.
-
But why? :palm:
Not even entertaining...

I agree. I did things such as the one in the video when I was 6 or 7 years old. After seeing a few broken toys (and my brother go ballistic) my dad started to teach me about cautious use of tools. Despite it took some time I improved a lot, as I could reassemble most of the subjects of my "experiments".
Showing its guts is different than knowing something but I guess patience, tenacity and perseverance don't pay off in a video for a more general audience.

Don't ask why.
This Lady has nearly 6 Million subscribers and all she does is unboxing toys. :scared:

23 minutes beard scratching video, wtf... I've just lost faith in humanity... Maybe I should do a vid of my trusty old Weller Magnastat, just sitting there in its stand, clicking and clacking for a full 12 hours. I'll think about it... :palm:

You hit the nail right on the head sir. Couldn't have said it better myself.

Just look at what they wear! All brand-name clothes and they aren't exactly learning anything at the end of the day. :palm:

I got into electronics quite in the same way just by taking things apart as a kid (well I mean i still am in a sense) and putting them BACK together. Now I build computers, fix phones, open electronics to try and fix them, and just toy around with almost anything I buy! Originally I wanted to be in the IT Industry, but now I am an Electrician which a lot of the things I've learned from taking things apart and the internet helps me out tremendously in the field when it comes to lighting control and other "low voltage" systems.

That beard scratching video is probably a spoof of those weird ASMR videos on YT.
These basically boil down to hot chicks wispering and making various sounds on a binaural mic.
Some examples:

Looks like the rear wheels are driven by a separate motor each.
The car probably turns by differing the speeds of each of the rear wheels, because the front wheels are fixed and cannot turn.

In the video you can see that the cars are using Bluetooth, a KnFR51822 module, which you can buy here (http://world.taobao.com/item/45510548687.htm?fromSite=main&spm=a312a.7700824.w4004-11064813601.3.oGoDld). But I can't find more technical information about it. 40 RMB ($6) is not expensive for a low energy Bluetooth module with an ARM Cortex M0 CPU. I wonder if you can run custom programs in the CPU. In the video you can see two extra chip-on-board chips on the back, which might be additional CPUs. Maybe not easy to integrate your own program with realtime requirements in the Bluetooth module.

it is true "solder spreading" artistry of the "yous godda do what yous godda do" influence
-
Nordic website provides all you need.
Thanks, https://www.nordicsemi.com (https://www.nordicsemi.com) looks good, but I can't find information about the KnRF51822 module. They don't produce it, only the chips and some nice Bluetooth dev boards and gadgets.
-
Nrf, nor knrf.
Right, the chip is the nRF51822, but you still need an antenna. And then you need to do the certification etc. With a module like the KnRF51822 it is much easier. Just solder the module in your product and you are (mostly) done. I guess that's the reason why the racing cars used this instead of the chip. Might be silly for their production volume, because they are even using additional chip-on-board chips, so why not just the nRF51822 chip and then integrating the antenna on the main board?
-
Ok, this makes sense. Would be still useful to have a datasheet of the KnRF module, but you can kind of see how the outer connectors are connected to the chip, because looks like a 2 layer board.

One person in their comments said "they are Mormons" --------Don't you just hate Spellcheck?
Mormons is correctly spelled.
Yes. But m-o-r-m-o-n-s is not the correct spelling of morons, which was vk6zgo's astute joke!
