@@Alacritousthe weird thing is that now that we discovered we could put plugs in the wall, we kinda don't use those adapters anymore...

@greatscottlab its quite common in the United States. So much so that you can get them at hardware stores for pretty cheap, about $3 or so. You can even get adapters that extend the socket outward and add two outlets to them, that way you can keep your light! Not that I recommend plugging much into them.
Yeah that was what we used in old basements and garages. I have a few but haven’t seen one in use for decades since it is more common to put in more in walls during new build/remodels
Socket adapters are very useful when you have work to do in unknown place, where you often have trouble to get access to wall sockets, but light fixtures are on the outside.
Well it’s fine if you don’t pull too much current but realistically it’s not a good idea. Light circuits only have 6 amp fuses and are usually 1 or 1.5mm twin and cpc.

I also bought two tubes of the liquid electric tape and made the same experience. One recommendation regarding angle grinder adapters: NEVER buy adapters or use an angle grinder for something it was not intended for. The speed and torque of angle grinders is very high by design and if something breaks at these rpm, it turns into a bullet! Just search for angle grinder accidents! Nothing will protect you!
I also got this little microscope a while ago and found it useless for inspecting circuit boards as you do. But my kids love it. They can explore all kinds of things in and around the house with it.
You can get monoculars instead of this digital microscope. They're often advertised as watchmakers magnifying glasses. They cost little money and are pretty handy. I have one with 10x magnification, which helps me a lot with small labels on ICs. They're also a completely optical device, which I find quite nice.
Such an adapter is useful if you live in an apartment building and have a storage unit. Usually, these units don’t have power outlets, only a light source and a switch. With such an adapter, you can connect a device even in the absence of an outlet.
I think a better solution for the last use case would be to get a boom arm for your microscope. Then you can keep it set up and out of the way when not in use and easily reposition when doing something quick like reading IC markings.
Don't knock that light socket adapter, we used to use something similar with Y bulb socket adapters they even had independent switches in the Y adapters
Only things I don't like on the esp house automation board are: not auto powered from mains, you need a 12V DC ps, the traces to drive relay's coils are too near each other and ground and no galvanic separation?

@@gamingkingXit is totally different in many ways, but there is some overlap in where it finds use. It is an asphalt-solvent solution, not a vulcanizing rubber.
Back in college, I had an old briefcase with a PS2 and a small LCD TV in it that I'd bring to the lounge to play with friends after classes. I had one of those socket adapters and an extension cord in it in case we weren't near an outlet. The one I had was a little less scary though XD
those socket to light fixture adapters are great for holiday light strings, just plug them into the porch light and you can flip them on/off without leaving the house LUL
When i was an Electrician I used the light bulb socket adapter often. I used it most for toning out wires. Could you do it with out one yes 100%, but time is money and this is a super time saver.
In an ideal situation for the light source you have a 6A (maybe 10A) circuit braker, so from wire thickness point of view it should be fine (but still a bad design)
there wasn't anywhere in the video "Złodziejka" aka 3way power adapter from classic socket. He complained about going from light socket to standard socket. Light power wires are usually thinner in buildings and there is enough light for filling its capacity.
@ złodziejka in polish normally means adapter from lightbulb socket to 230v, commonly used in basements where you do not have sockets, but only lights. It is standard equipment at home here.
Great video! Average lamps switch can't handle usually over 5 amps. So that lamp socket outlet don't need to handle much power. But yeah things like that was used 100 years ago and are not for modern usage. I think you should test how much lamp switches can handle, contacts usually burn with switching higher loads with half year.
@NinoJoel I live in Estonia and i have seen similar things that are at least 50 years old from soviet times. Then it also was used at odd and extreme places like big apartement building basement where wasnt any outlet to illegaly use lights power for other things. But never seen moder one in use :D
@@loodusefilm7881 i have been traveling to the us as well and they still use so many things that you wouldn't find here outside some leftovers or museums 😁
Socket to outlet converters are most useful in places where the only electric available is a single light socket. Throw in the adapter, a small power strip, and you're functional if potentially unsafe.
Back in the day, if were renting a cheap flat/apartment there would be a coin-in-the-slot electricity meter. However the lighting circuit for all the rooms would not be fed from these meters so people would connect to the light socket for upto about 500 watts
The belt sander adapter is not intended for use on flat surfaces but only for hard to reach parts. Works fine as a belt sander but of course you don't have much sandpaper available so it wear out quickly.
I've noticed that the angle grinder bracket for my Makita performs better in woodworking applications than steel. While it may not be ideal, it's a cost-effective solution for mounting it to your existing tool, rather than purchasing a new one.
to 17 year old me, who was working on my first clunker in the underground garage of the apartment building the family lived in, the lightsocket outlet passthrough thing was a godsend. all i had was an old corded drill and a smallish trouble light running off it but that proved to be enough, if i had to guess this adapter was from the mid 80s cause i dug it out of a kitchen drawer
The bulb to plug adapter is something I've used with Christmas lights. I remove a bulb from the porch light and plug the string into that fixture. It's already high up near a roofline and I can use the switch inside the house to turn them off and on. Once the holidays are over all I have to do is screw the bulb back in and everything is back to normal.
A cheap and easy alternative to the digital microscope is taking a webcam and screwing the lens adapter so the focus is much closer. If you remove the webcam plastic casing, then the lens can fit easily between electronic components
Liquid electrical tape. Can be amazing, but buy it from a car parts store, hobby electronics store or hardware store. That way you can immediately return it if it is half cured like in the video. That said once exposed to oxygen, opening the tube, tub or similar, it goes off after a few weeks to months depending on brand, heat also seems to massively speed up the process.
I ordered some last week, the white one, same brand, same problem. Seal, manufacturing date and sell-by date were both to expect a decent product, but it ended up in the bin. Sell-by date was somewhere in 2026.
I used the US equivalent of that light socket to outlet adapter for years in a room that was poorly lit by it's single recessed light socket that was missing it's diffuser cover. So with minimal and completely reversable modification, I hung a florescent shop light that was powered by a wall outlet plug and used the adapter to power the shop light from the socket above it. This lit the room up way better. Then when we moved out, I was able to restore the original lighting setup by just removing the shop light.
I have a similar lamp power socket that is probably 70 be years old. However, it also has space for a bulb. I've been told they are used by painters who might paint a room and need extra lighting when all sockets are covered for painting. Makes a lot of sense!
6:52 in Europe, light installation is protected by max 10A fuse so you shouldn't be able to draw more than 10A anyway. But I also tend to think this is more intended for Christmas lights or something similar which is temporary and with a small current draw, as you mentioned.
5:30 this product is literally for stealing power. it is widely used to screw into a lamp socket on a circuit not metered by your apartment and then you can connect a cord or something and receive unmetered power.
I used those screw in adapters to install plug-in LED "tube" lights in place of dangling bulbs in porcelain fixtures in my basement. They're a common hardware store product in the US 😁 Mine are solidly made and UL listed though!
Light socket adapters have existed since the dawn of electricity in the US. It used to be there was only the light socket. And then there was a two-tiered system we're lighting was one price outlets for another. then there was the places with lack of outlets problem for a long time, so yeah it is interesting to see a modern take.
Sockets on lights are the first thing my dad showed me that blew my mind as a kid. I was so confused when i saw it, and i couldn't figure out the usage of it. My dad used to travel a lot for work, and sometimes, he stayed in hotels where the outlets were hidden or a different standard. He had that thing always with him. I honestly never understood it until I actually stayed in a very weird hotel where even the TV socket was panted in the wall with no access to it. (Dont ask me why i still dont know)
I believe the magnifier that you have is normally used in handwriting/signature/autograph verification. It’s used to see the ink, whether it was an auto pen or authentic handwriting, and aids being able to detect forgeries.
Regarding the light bulb fitting electrical sockets, there's a BBC programme about weird/dangerous things the edwardians did that could adversely affect one's life expectancy. A ~125 years ago version of those fittings was prominently featured. While they never went away, they're still probably a questionable proposition, but hey, so is the world right now.
The outlet in light socket thing isn't so weird, in my opinion. There are old houses which have very few outlets and extra light sockets for no apparent reason. That's when you would use this adapter. Have no outlet? Have an extra light you never use? Cheap and not handy? Buy this! It has its use.
Those socket outlets are a lifesaver. I use better quality version. I added led lighting in my garage. I plugged the led shop lights into a socket adapter for the old incandescent bulb. Now I can use the regular wall on off switch. I also put two in the incandescent sockets on my garage door opener, now I have two bright led shop lights that come on when I open the garage door
For reading the labels on chips etc, a "loupe" lens can be handy, and very quick/simple to use. I recently bought a very cheap set from aliexpress and they're fine.
Actually, I use a light bulb socket converter that not only includes the outlet, but extends the socket so you can still use a light bulb. Pop that bad boy in for outdoor holiday lights, just switch on the porch light and the whole front of the house is lit up.
About the outlet for the light socket, the issue with the contacts exposed is quite normal in japan, Thailand, US etc, They all have the pins without insulation. Also I can see ppl using this in Indonesia when like you've mentioned, they don't have plugs sometimes but only light sockets
The Problem with the socket adapter is also that the power rating of most lamps are low - like 40, 60 or 100W. Could get quite hot in the ceiling or in the lamp base if you draw a lot of current.
Here in the states, i've seen the lightbulb to receptacle adapter used in basements to replace a single bulb fixture with a strip light (fluorescent years ago, but LED now) that way you can use extant wall switches to control the new lights.
My last house was very old, and as such had very few wall outlets (it was built without electricity) so I found several of the light socket adapters left behind. They were used pretty frequently way back when houses were initially only wired up to provide light, then with more inventions to use electricity they started installing wall sockets. I’ve used the socket adapters a few times when we lived there simply because it was the closest available. One bedroom at that house actually even never got wall outlets installed, the single light fixture in the middle of the ceiling was the only power in the room!
That "belt sander" attachment is more for reaching into tiny places than use on plate steel. I'm sure the ali express version does indeed suck but bandfiles (what we call those over here) are mostly used in auto body and pipe work to clean up welds and cutting burrs.
Its funny that I needed a bulb to power socket adapter last week and had to make one myself. One use case for having one of those is if you have to work on your electrical system. In my example one of the wall sockets exploded and since the genius that made the power network in my house routed power to all the sockets in my house through that one socket (I guess that's why it exploded) I had no power. No power = no power tools = no ability to fix the socket. With this adapter I was able to get power from one of the lamps and use it to fix the socket. eidt: Those adapters can handle 10A, since that is what lights are fused with. Its less than 16A used in wall sockets by design (no one is going to push more than 10A of power through lamp, so cheaper wires can be used for the lamp power network)..
Well, that socket is quite old. But, in those days, the light-fittings were mostly safer with 'stone' outside or bakalite with the contacts deep inside (at least here in my country) so you could never touch them. Also by regulation: the small contact was the live... although not every place was hooked up this way. And current: you can use a light-socket only for a few amps anyway. I used those kind of sockets many times in the past, especially in hostels or hotels or other rooms like that without sockets. To put power on a charger or coolingbox for example. So low-loads only.
Lamp sockets usually do not have thick wires, so you don't need thick wires in lamp-socket-outlets. You can't safely use it for e-teapot or something like this. Imagine old 100 Watt lamp - its less than 0.5A (in 220v).
For the microscope: It looks like one of those very cheap cam units they used back in the days - you can try to turns the black lens holder to adjust focus - that's how it worked in those things back then. If you get it to focus a further distance it would also decrease the magnification ratio.
That "belt sander" is a finger linisher, you can get good belts for them, cheap belts will wear out fast. They are only a detail sander and not intended to sand large areas, you should only use the tip of the roller, and not the flats which is probably why you had issues with it melting the plastic.
Light bulb socket adapters are fairly common in the USA. We use them every year to plug in our Christmas lights, and I got them in a local store without needing AliExpress.
Sockets that screw into a light socket is something I kept in my pocket everyday as a farmer because dragging hundreds of feet of extension cords around is foolish with lights every 6 feet
You should have done a Christmas special! With items many people may buy as presents. Sure, these could very well be presents but you didn't title the video as such! Keep doing these! I love em
turn the camera lens inwards to extend the focal point further from the camera sensor. They might have some silicone on the threads to hold it in place but it shouldn't be too difficult to wiggle free and adjust focus as needed.
Die E27 Steckdose ist auch alles andere als legal. Es darf nicht möglich sein, Schuko Stecker dort einzustecken, aufgrund der fehlenden Erdung. Nur Stecker vom Typ C sollten dort hineinpassen dürfen.
Light socket outlets aren't 'wild'. They've existed forever. They were a staple back when electrification was first happening. I have one in my closet that goes between the bulb and outlet.
Not sure what you are expecting of that grinder attachment.. it's meant for fine work, which with some decent belts it seems like it would be. Surprisingly decent for the cost, I was a little shocked..
6:17 To be fair, light fixtures also usually use thin wires - if the load is high, either the wire insulation will start melting in the wall or the protection will trip(if the correct circuit breaker was used)
Oh wow what a channel, what a series! I can now enjoy my favourite past time, exploring weird aliexpress things, without turning my home into a junkyard at my own expense.
Socket fixtures can be used to steal power from your apartment complex or similar. We used to do this with a homemade outlet that screwed into a socket.
I use the light bulb to power socket to find out which circuit a room has but it is only connected to lights. Connect something loud like a box fan, turn it on. Go through the circuit breakers until the fan turns off
Lamp converter - very stupid idea, most lighting circuits are about 6 Amps, people might easily blow their lighting circuits, especially as there is no fuse in the adapter. You should also check what certifications it has - it is actually legal.
Most countries don't have fuses in the plug so absolutely no difference. The breaker will protect from any overload however lack of earth so no class 1 appliances.
I noticed you were using crocodile clip cables that looked like they might have been bought online. I recently discovered they are often made from steel rather than copper or even aluminium wire as the wire is magnetic. I just thought it worth mentioning as you were using a milliohm meter with it.
we used the E27 to US plug for converting bulb receptacles to tube led light, instead of rewiring the whole thing or adding switches to other wall sockets.
Sockets in light fittings were actually used before we got them on the walls!
Yeah. there's nothing new or weird about those.
there still kinda common, once in a wile i see them at walmart and hardware stores designed more for outdoor use, there just made way better lol
The only time i saw getting power from a lamp holder was in a Laurel & Hardy movie.
Aren't Germans funny?
@@Alacritousthe weird thing is that now that we discovered we could put plugs in the wall, we kinda don't use those adapters anymore...
Sure in a pinch they work, but most countries ask for less power in the lighting circuit which means you can overload the circuit if you plug a big load.
Also, even if you don't overload the circuit, you will probably overload the plug as they're made expecting loads of less than 150/200W.

They're also a completely optical device, which I find quite nice.
Such an adapter is useful if you live in an apartment building and have a storage unit. Usually, these units don’t have power outlets, only a light source and a switch. With such an adapter, you can connect a device even in the absence of an outlet.
I think a better solution for the last use case would be to get a boom arm for your microscope. Then you can keep it set up and out of the way when not in use and easily reposition when doing something quick like reading IC markings.
14:45 you need angle grinder with build in speed regulation, so you can slow it down
And I don't think you're supposed to apply pressure anywhere except at the tip where the bearing is, but the plastic should not be that cheap either.
That handheld microscope could be quite useful for close up examination of edges when sharpening knives etc
Don't knock that light socket adapter, we used to use something similar with Y bulb socket adapters they even had independent switches in the Y adapters
That one is a piece of crap. If you have to use one, at least get one that the plug doesn't fall out of.
Only things I don't like on the esp house automation board are: not auto powered from mains, you need a 12V DC ps, the traces to drive relay's coils are too near each other and ground and no galvanic separation? IDK if what that chip internally is but some optocouplers would have given me a better feeling.
For reading those ICs, maybe get a Jewler's loupe? Smalll enough for tight spaces, high magnification and no battery required.
At least in the US that liquid tape is basically found everywhere, usually in the automotive section of a Walmart
Ok. Fun fact
It looks just like RTV (room temperature vulcanizing) silicone gasket for an engine.
@@gamingkingXit is totally different in many ways, but there is some overlap in where it finds use. It is an asphalt-solvent solution, not a vulcanizing rubber.
@@gamingkingX The stuff that I've used sets up a lot harder than silicone.
@@rocketman221projects ah okay, then just replace “silicone” with “pvc” and its basically the same.
Back in college, I had an old briefcase with a PS2 and a small LCD TV in it that I'd bring to the lounge to play with friends after classes. I had one of those socket adapters and an extension cord in it in case we weren't near an outlet. The one I had was a little less scary though XD
those socket to light fixture adapters are great for holiday light strings, just plug them into the porch light and you can flip them on/off without leaving the house LUL
Yep. Pretty much the only good usage I see for them ;-)
Socets also was used for "service crews" to plug tea pots in common places (staircase) @@greatscottlab
Glad you liked the ESP home multifunction board :)
When i was an Electrician I used the light bulb socket adapter often. I used it most for toning out wires. Could you do it with out one yes 100%, but time is money and this is a super time saver.
In an ideal situation for the light source you have a 6A (maybe 10A) circuit braker, so from wire thickness point of view it should be fine (but still a bad design)
The lamp sockets nowadays only handle 200w or less.
It's not a wire issue
Watching your video for more than 4years . I love your videos ❤. I learned a lot, i can't thank you enough for that
It is fun for Polish people, to see German guy is suprised about "Złodziejka" , what is commonly used in Poland since 966y
there wasn't anywhere in the video "Złodziejka" aka 3way power adapter from classic socket. He complained about going from light socket to standard socket.
Light power wires are usually thinner in buildings and there is enough light for filling its capacity.
@ złodziejka in polish normally means adapter from lightbulb socket to 230v, commonly used in basements where you do not have sockets, but only lights. It is standard equipment at home here.
in the Czech Republic we call it the same "zlodějka"
2:43 Subtle flex with that behemoth of a keysight
That scope multimeter now has a FFT function. I did not test it much though
Really? Will try that out.....
@ th-cam.com/video/PWPkhcwcsqs/w-d-xo.html&lc=Ugz1G3fF_lLrFJ23odx4AaABAg&si=3rrtx80kttYeG7Od
Btw, I just love your ali videos 😊
Great video! Average lamps switch can't handle usually over 5 amps. So that lamp socket outlet don't need to handle much power. But yeah things like that was used 100 years ago and are not for modern usage. I think you should test how much lamp switches can handle, contacts usually burn with switching higher loads with half year.
Funnily enough these are common in the US... Well... They are behind a 100 years in some things 😂
@NinoJoel I live in Estonia and i have seen similar things that are at least 50 years old from soviet times. Then it also was used at odd and extreme places like big apartement building basement where wasnt any outlet to illegaly use lights power for other things. But never seen moder one in use :D
@@loodusefilm7881 i have been traveling to the us as well and they still use so many things that you wouldn't find here outside some leftovers or museums 😁
Socket to outlet converters are most useful in places where the only electric available is a single light socket. Throw in the adapter, a small power strip, and you're functional if potentially unsafe.
Back in the day, if were renting a cheap flat/apartment there would be a coin-in-the-slot electricity meter. However the lighting circuit for all the rooms would not be fed from these meters so people would connect to the light socket for upto about 500 watts
The belt sander adapter is not intended for use on flat surfaces but only for hard to reach parts.
Works fine as a belt sander but of course you don't have much sandpaper available so it wear out quickly.
I've noticed that the angle grinder bracket for my Makita performs better in woodworking applications than steel. While it may not be ideal, it's a cost-effective solution for mounting it to your existing tool, rather than purchasing a new one.
to 17 year old me, who was working on my first clunker in the underground garage of the apartment building the family lived in, the lightsocket outlet passthrough thing was a godsend.
all i had was an old corded drill and a smallish trouble light running off it but that proved to be enough, if i had to guess this adapter was from the mid 80s cause i dug it out of a kitchen drawer
The bulb to plug adapter is something I've used with Christmas lights. I remove a bulb from the porch light and plug the string into that fixture. It's already high up near a roofline and I can use the switch inside the house to turn them off and on. Once the holidays are over all I have to do is screw the bulb back in and everything is back to normal.
A cheap and easy alternative to the digital microscope is taking a webcam and screwing the lens adapter so the focus is much closer. If you remove the webcam plastic casing, then the lens can fit easily between electronic components
Liquid electrical tape. Can be amazing, but buy it from a car parts store, hobby electronics store or hardware store. That way you can immediately return it if it is half cured like in the video. That said once exposed to oxygen, opening the tube, tub or similar, it goes off after a few weeks to months depending on brand, heat also seems to massively speed up the process.
I ordered some last week, the white one, same brand, same problem. Seal, manufacturing date and sell-by date were both to expect a decent product, but it ended up in the bin. Sell-by date was somewhere in 2026.
I used the US equivalent of that light socket to outlet adapter for years in a room that was poorly lit by it's single recessed light socket that was missing it's diffuser cover. So with minimal and completely reversable modification, I hung a florescent shop light that was powered by a wall outlet plug and used the adapter to power the shop light from the socket above it. This lit the room up way better. Then when we moved out, I was able to restore the original lighting setup by just removing the shop light.
I have a similar lamp power socket that is probably 70 be years old. However, it also has space for a bulb. I've been told they are used by painters who might paint a room and need extra lighting when all sockets are covered for painting. Makes a lot of sense!
6:52 in Europe, light installation is protected by max 10A fuse so you shouldn't be able to draw more than 10A anyway. But I also tend to think this is more intended for Christmas lights or something similar which is temporary and with a small current draw, as you mentioned.
5:30 this product is literally for stealing power. it is widely used to screw into a lamp socket on a circuit not metered by your apartment and then you can connect a cord or something and receive unmetered power.
I used those screw in adapters to install plug-in LED "tube" lights in place of dangling bulbs in porcelain fixtures in my basement. They're a common hardware store product in the US 😁 Mine are solidly made and UL listed though!
4:55 this is very cool. I am pretty sure that there is an FPGA in there
Light socket adapters have existed since the dawn of electricity in the US. It used to be there was only the light socket. And then there was a two-tiered system we're lighting was one price outlets for another. then there was the places with lack of outlets problem for a long time, so yeah it is interesting to see a modern take.
Sockets on lights are the first thing my dad showed me that blew my mind as a kid. I was so confused when i saw it, and i couldn't figure out the usage of it. My dad used to travel a lot for work, and sometimes, he stayed in hotels where the outlets were hidden or a different standard. He had that thing always with him. I honestly never understood it until I actually stayed in a very weird hotel where even the TV socket was panted in the wall with no access to it. (Dont ask me why i still dont know)
I believe the magnifier that you have is normally used in handwriting/signature/autograph verification. It’s used to see the ink, whether it was an auto pen or authentic handwriting, and aids being able to detect forgeries.
Regarding the light bulb fitting electrical sockets, there's a BBC programme about weird/dangerous things the edwardians did that could adversely affect one's life expectancy. A ~125 years ago version of those fittings was prominently featured. While they never went away, they're still probably a questionable proposition, but hey, so is the world right now.
The outlet in light socket thing isn't so weird, in my opinion. There are old houses which have very few outlets and extra light sockets for no apparent reason. That's when you would use this adapter. Have no outlet? Have an extra light you never use? Cheap and not handy? Buy this!
It has its use.
Those socket outlets are a lifesaver. I use better quality version. I added led lighting in my garage. I plugged the led shop lights into a socket adapter for the old incandescent bulb. Now I can use the regular wall on off switch. I also put two in the incandescent sockets on my garage door opener, now I have two bright led shop lights that come on when I open the garage door
For reading the labels on chips etc, a "loupe" lens can be handy, and very quick/simple to use. I recently bought a very cheap set from aliexpress and they're fine.
Actually, I use a light bulb socket converter that not only includes the outlet, but extends the socket so you can still use a light bulb. Pop that bad boy in for outdoor holiday lights, just switch on the porch light and the whole front of the house is lit up.
About the outlet for the light socket, the issue with the contacts exposed is quite normal in japan, Thailand, US etc, They all have the pins without insulation. Also I can see ppl using this in Indonesia when like you've mentioned, they don't have plugs sometimes but only light sockets
The Problem with the socket adapter is also that the power rating of most lamps are low - like 40, 60 or 100W. Could get quite hot in the ceiling or in the lamp base if you draw a lot of current.
Here in the states, i've seen the lightbulb to receptacle adapter used in basements to replace a single bulb fixture with a strip light (fluorescent years ago, but LED now) that way you can use extant wall switches to control the new lights.
My last house was very old, and as such had very few wall outlets (it was built without electricity) so I found several of the light socket adapters left behind. They were used pretty frequently way back when houses were initially only wired up to provide light, then with more inventions to use electricity they started installing wall sockets. I’ve used the socket adapters a few times when we lived there simply because it was the closest available. One bedroom at that house actually even never got wall outlets installed, the single light fixture in the middle of the ceiling was the only power in the room!
The socket to plug adapter is perfect for security camera installation outside. Low draw applications is exactly what these are used for.
to measure the resistance of the connectors just put 10 of them in series and divide by 10.
That "belt sander" attachment is more for reaching into tiny places than use on plate steel. I'm sure the ali express version does indeed suck but bandfiles (what we call those over here) are mostly used in auto body and pipe work to clean up welds and cutting burrs.
Its funny that I needed a bulb to power socket adapter last week and had to make one myself.
One use case for having one of those is if you have to work on your electrical system.
In my example one of the wall sockets exploded and since the genius that made the power network in my house routed power to all the sockets in my house through that one socket (I guess that's why it exploded) I had no power. No power = no power tools = no ability to fix the socket.
With this adapter I was able to get power from one of the lamps and use it to fix the socket.
eidt:
Those adapters can handle 10A, since that is what lights are fused with.
Its less than 16A used in wall sockets by design (no one is going to push more than 10A of power through lamp, so cheaper wires can be used for the lamp power network)..
Well, that socket is quite old. But, in those days, the light-fittings were mostly safer with 'stone' outside or bakalite with the contacts deep inside (at least here in my country) so you could never touch them. Also by regulation: the small contact was the live... although not every place was hooked up this way.
And current: you can use a light-socket only for a few amps anyway.
I used those kind of sockets many times in the past, especially in hostels or hotels or other rooms like that without sockets. To put power on a charger or coolingbox for example. So low-loads only.
Lamp sockets usually do not have thick wires, so you don't need thick wires in lamp-socket-outlets. You can't safely use it for e-teapot or something like this. Imagine old 100 Watt lamp - its less than 0.5A (in 220v).
I’m intrigued by the apparent auto dubbing from German to English, for the American viewers, this is amazing.
For the microscope: It looks like one of those very cheap cam units they used back in the days - you can try to turns the black lens holder to adjust focus - that's how it worked in those things back then. If you get it to focus a further distance it would also decrease the magnification ratio.
That "belt sander" is a finger linisher, you can get good belts for them, cheap belts will wear out fast. They are only a detail sander and not intended to sand large areas, you should only use the tip of the roller, and not the flats which is probably why you had issues with it melting the plastic.
Light bulb socket adapters are fairly common in the USA. We use them every year to plug in our Christmas lights, and I got them in a local store without needing AliExpress.
Sockets that screw into a light socket is something I kept in my pocket everyday as a farmer because dragging hundreds of feet of extension cords around is foolish with lights every 6 feet
You should have done a Christmas special! With items many people may buy as presents. Sure, these could very well be presents but you didn't title the video as such!
Keep doing these! I love em
Those adapters are for renovations, used to use them during renovations when we had light routed, but didnt had sockets yet.
turn the camera lens inwards to extend the focal point further from the camera sensor. They might have some silicone on the threads to hold it in place but it shouldn't be too difficult to wiggle free and adjust focus as needed.
Die E27 Steckdose ist auch alles andere als legal. Es darf nicht möglich sein, Schuko Stecker dort einzustecken, aufgrund der fehlenden Erdung. Nur Stecker vom Typ C sollten dort hineinpassen dürfen.
Dieses "liquid electrical tape" musst du in warmen Wasser aktivieren, dann funktioniert es prima! Der Tipp kommt vom Verkäufer.
Light socket outlets aren't 'wild'. They've existed forever. They were a staple back when electrification was first happening. I have one in my closet that goes between the bulb and outlet.
Not sure what you are expecting of that grinder attachment.. it's meant for fine work, which with some decent belts it seems like it would be. Surprisingly decent for the cost, I was a little shocked..
6:17 To be fair, light fixtures also usually use thin wires - if the load is high, either the wire insulation will start melting in the wall or the protection will trip(if the correct circuit breaker was used)
5:11 I've actually built this exact thing when I was a kid, using a broken CFL bulb socket and an old outlet! 😄
Oh boy
Oh wow what a channel, what a series!
I can now enjoy my favourite past time, exploring weird aliexpress things, without turning my home into a junkyard at my own expense.
Socket fixtures can be used to steal power from your apartment complex or similar. We used to do this with a homemade outlet that screwed into a socket.
I love this series even though I have to admit that the belt sander attachment I bought works pretty good. I wouldn't wanna miss it.
Sockets in lamp fittings go crazy for retro fitting old bulb lights with led panels in sheds and garages
That light bulb to power socket adapter might be useful for hotels or other situations where you might not have any access to power sockets otherwise.
I use the light bulb to power socket to find out which circuit a room has but it is only connected to lights.
Connect something loud like a box fan, turn it on. Go through the circuit breakers until the fan turns off
Lamp converter - very stupid idea, most lighting circuits are about 6 Amps, people might easily blow their lighting circuits, especially as there is no fuse in the adapter. You should also check what certifications it has - it is actually legal.
Most countries don't have fuses in the plug so absolutely no difference. The breaker will protect from any overload however lack of earth so no class 1 appliances.
I noticed you were using crocodile clip cables that looked like they might have been bought online. I recently discovered they are often made from steel rather than copper or even aluminium wire as the wire is magnetic. I just thought it worth mentioning as you were using a milliohm meter with it.
I always used those bulb outlets for Christmas lights. The best ones have the outlet and still accept a bulb
we used the E27 to US plug for converting bulb receptacles to tube led light, instead of rewiring the whole thing or adding switches to other wall sockets.
