1. Messy but works is kind of what you want with fire extinguishing. It's not like you can just induce a vacuum on Earth where ever you want. I'd rather be certain the fire is out and deal with clean up, instead of being confident that there won't be a mess but not having anything to clean up because the fire got out of control anyway.
2. The USB panel would fit in NA junction boxes which are square/rectangular. I could see it being a nice addition at or above waist height near an outlet so you have a wall outlet that can charge your phones and tablets.
3. Ha. That nail gun is _not_ meant for wood. That's definitely for the limited application of nailing something to stone, or nailing metal to something. A proper nail gun is commonly pneumatic, but they also have solenoid powered ones now. Those will all drive nails into wood, and come with a magazine of nails to plunk them into wood. Honestly fasteners for wood joining is kind of crap. I like the Japanese method of cutting your joins so the wood merges seamlessly. But we take what we can get in NA.
4. The AI gizmo is novel, but kind of expensive. Happily it seems you can hook it up to a remote service, so the on board edge AI (probably a Qwen 2B model from years ago) is replaceable with modern models and remote calls. That's good, if you host locally.
5. The smoke machine is a bit of a let down. If it could smoke for longer periods of time I think it would be interesting for a multitude of uses, from ambiance to gags.
6. I've seen these toys before. I saw one which I thought was AI controlled, homing in on a hand it detects nearby. It lets you play a kind of auto-catch where the ball can't miss very easily. The battery on this one is kind of annoying though. 5 minutes for a 30 minute recharge I'd swap that out real quick.

In more developed countries, there are regulations governing product safety and supplier liability. I would never ever buy safety-related or potentially hazardous products directly from China, nor would I buy products that rely on a Chinese cloud service.
I admit that this can sometimes be difficult, whether because of the prices or because the product isn’t available anywhere else. But unfortunately, eben some importers seem to have no real quality control or don't really understand how a device should work. In that respect, some are becoming more and more like the (often already counterfeiting, often small manufacturers.
On top of that, small Chinese manufacturers sometimes throw things together like chop sueyonly, in the end, it doesn’t taste good, makes no sense but nonsense.
Sorry.

Nails often time are a lot stronger and hold a lot better than a screw does. It may seem counterintuitive, but screws are usually made of a harder material which means it's more brittle and so the sheer strength and the cut strength is a lot lower than a nail. We're a nails sheer strength is absolutely insane Plus you can bend a nail and put it in and re-vent it straight. This is why America doesn't use screws for a lot of construction and we depend on actual nails because they are a lot faster, stronger and nails like framing nails that are hot dipped actually have a glue that is part of it and that's the outside of it so when you drive it through the heat of the nail driving through actually melts the glue and holds that nail in an epoxy and that's the reason why nails don't pack out either

The mini smoke machine is in design similar to a vape. Just slap a fan within the path and use a liquid without aroma and nicotine. The basic fluid is the same. I'm surprised that they sell it that expensive. When I look at vapes, they sell for way less. A fan and a remote shouldn't be that expensive. My own vape did cost around 50 10 years ago and it uses switchable 18650 batteries, holds 4ml liquid and the coil is replaceable.
With the ball toy, I bought one from Lidl a few years ago and its a piece of crap. It broke quickly. Also the version I had, had no remote and turning it off, when it starts to spin, when moved, made it hard to turn off, as the power switch also spun. Also its not safe for hair, as it caught in my hair and pulled some out.

For future reference: always consider if using the don't forget phrase makes sense, or if remember is better. How and why would I not forget about something I didn't plan nor want to remember in the first place XD You have to encourage a viewer to visit a sponsor's site, not make it sound like an unwanted chore! :D You should rather say remember to visit the. (sponsor's website) or better yet I invite you to visit the. If it's new to me then I can't not forget it. If it's new I have to be invited to get to know it. Logic! And fundamental people's skills.
I know that in German language there isn't a direct remember, hence the tendency to directly translate the nicht vergessen phrase, but I think that wouldn't be a problem for a smart man. :)

Explosive Nails (or in this case, very very offbrand 'Ramset') is very useful for sure, it's just situational. if you're trying to affix Metal or Concrete, Et Cetera together, sometimes even Wood - it's not always practical to Drill a hole to use a Bolt.
in those times that it isn't practical, you can fire a Nail through instead and you'll get a fairly good hold instantaneously.
fairly situational but in those situations it's about the best possible thing for the job.
with the less offbrand stuff, the adjustment is generally via different classes of explosive charges, so that there's no need to adjust anything on the Tool at all. you pick the Color of Nail that matches the driving power that you need for the task.

I used something similar but much better than that one. There are two types. One is hammer actuated, the other is like a ggunn with a trigger. But it uses a small piece that looks like the ggunnpowder section without anything else. You buy the ones with the correct amount of power. Most common usage here is a 2x4 or 2x6 nailed into a concrete slab for a house. The other common use is wood onto metal. You just buy the correct nails with a washer. Then the correct powered cartridge. I used these for years. The hammer blow on top holds it all down when it fires. Those types are quite inexpensive but slow to use. The one you used looks super expensive. Be 100% certain to use hearing protection!

2: 35 if it's a lithium ion battery, there is really not anything that can be done to extinguish the fire once it has started. The lithium fire is self oxygenating so a device like this won't likely improve the situation in any meaningful ways if there is a lithium fire. Again, I don't know of a technology that can put out a lithium battery fire. I inspect residential and utility scale energy storage and PV systems for a living. Most utility scale bess systems will have some token fire suppression system, the main benefit in my eyes is an opportunity to stop something like an electrical fire from spreading to the batteries.

Interesting nail gun. That's technically a specific class. Most of the time those are used for nailing wood to concrete. You would frame the wall, lean it up and then nail it straight into the concrete without having to drill anything. Does it save that much time Slightly but you're also majorly putting your hearing on the line and guaranteed to have hearing damage with the ricocheting gun blasts. Plus you can also blow out the concrete. The pneumatic and now more so electric nail guns take varying sizes so they're more used for anywhere where you would swing a hammer to attach things together usually wood to wood.

WARNING: I buy plenty of stuff from Ali but will NEVER buy any 240V to USB devices, in Australia we had 28 year old mother of two die from electrocution when an un-certified illegally imported Chinese USB charger (which she bought from a shop) shorted out and sent 240V down the headphone lead, killing her, they found her with badly burn chest and ears, the shop owner was charged for supplying an un-certified illegaly imported device, she was fined and I think went to jail.
If it runs on 12V I'm ok with it, if it runs on 240V STAY AWAY, only stick with certified brand name devices, the risk is not worth it.

2: 20 Even If might work for Fire in Electric Panels. This Will Not put out Fires with LiIon & related Batteries in Thermal Runaway. 4: 00 If you want Higher Energy Bills, all USB power units like shown & more suck Power 24/7/365 even without other things plugged into them. 6: 25 Some Counties you need a Firearm License or other License/Certs to Have &/or Operate Gun type like above or other Ramset types, Gas types like many Paslode units, Compress Air type or all types of Nail Guns. Even without Government issues, Companies or Insurance Co's can cause problems too during use or after a bad event.

The problem with Aliexpress is there are too many fraudulent seller. Ship wrong items or defect product. In the return/refund process, Aliexpress makes it so difficult and impossible, and always sided with seller. If you are buying anything over $3, and you want return/refund, good luck to you. Fraudulent sellers are everywhere, but Aliexpress shouldn't protect them. That make Aliexpress trustless. Honestly, I like to find inexpensive products in Aliexpress, but never never buy something over $3. Because I got screwed too many times. It was not like that before.

5: 32. You can't use FNB-58 like that!
I got one and made the same mistake myself. When you plug in any of the ports into it and go to the pd/qc trigger that voltage is shared on all of type a/b/c male/female sides. You were back feeding that voltage into the power bank.
The only port where voltage isn't back feed is the top micro b port that is used for data and standalone power so you can measure voltages under 3v (and current more precisely.
You don't need separate power source for it when you are testing pd capabilities of type c charger.

greatscottlab can you make speed regulator becauwe i cant figure out why i have like power loss on moseft and i think i know why but im using wemos d1mini clone and mosefts and oled display and potentiometer and why mosefts dont give full power because gate voltage is 20 or 10 i dont remmember but here is moseft module FTP16N06A but wemos does only3. 3 logic voltage is that why and voltage drop on max was 2volts dropped from 12volt to 10volts

be very very careful with the aerosol product to stop fire!
it's absolutely not effective, too bad that you not talk about the fact that the source of the fire will be always there. even if a fire is stopped, if the problem is too much current and nothing stop the power source, the fire will come again!
this must be implemented with over current protection (that have been defective if fire is here)

I bought one of those drone balls, for my (then) 10 year old. Around that age, sensible enough not stick fingers in. It does take practice. It's more fun with two people. You can throw to each other in long sweeping arcs. In low light is better to see the lights. Like all toys, will get bored of it eventually and then rarely use anymore. But for what it is, and as long as our interest lasted, we like it

In Australia we have many powder activated tools, I have a HILTI nail gun, it uses. 27 caliber cartridges, these are built extremely strong, there is NO WAY I would trust that 12 nailgun you showed, it's likely to blow apart ending up with someone getting seriously hurt, I know it might be a novelty for someone in Germany, but I would be putting it in the bin that's just an accident waiting to happen.

I bought a pair of those ball toys about 6 years ago and while they looked great they didn't fly well enough even indoors for me to use them more than once, I did manage to freak out the ferrets when one of the balls bounced into their play tubes and they all shot out in a hurry with their tails fluffed up. Nobody was hurt and they tried to hide the toy behind the sofa once the battery ran out.

The only item I will purchase from AliExpress is an esp32 board. Electronic components are mostly spaced incorrectly and are marginal. Resistors with steel wire etc. and most other items they sell are usually in misleading ads you really have to be careful and most items are too expensive for what they are. It’s not the source of reasonable deals it was a few years ago. Just My Opinion

That nailer thing that you're using is basically a Chinese version of a ramset. Where it uses basically the casing of a 22 that is basically just a casing squeeze together with gunpowder and a primer and whenever the hammer on the back hits the primer that many explosion drives the nail in those are not used for wood, those are used for concrete driving nails through concrete
