@@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. Even if you're not overloading anything, those plugs have no ground, so they're risky to use. It's not gonna kill you instantly, but your friendly neighborhood inspector is not gonna be happy if they see you using it
I used to live in staff accommodation in a hotel. They would turn off the power sockets at 10PM every night to prevent gatherings/parties, so we hooked up an extension to the light socket. That socket adapter would have been very handy. 😆
@@zaks7it's super easy to open and replace the 18650 inside. I agree the battery that it ships with is trash, but with a reputable 18650 it lasts a lot longer. The battery it has inside isn't even soldered so it's not very hard to switch at all.
Some time ago I had my gas water heater replaced, and in the toolbox of one of the workers, was a homemade bulb to socket adapter, made from soviet-era parts. When I asked him about it, he explained that he also does roof and attic repairs, and in my area, It's uncommon to have sockets in attic, but we usually have lights so he used it for some low power stuff
Had a similar case in a garage not having sockets, but a lamp. Being able to use like a small vacuum cleaner there was a game changer, using an old one. It also had lamp passthrough. Never left unattended though.
I've seen the same thing used to power outside christmas lights off an outside light fixture when there wasn't an outside receptacle close by, and bonus no need to unplug to turn them off, just use the switch :P
You can use battery internal resistance meters to measure any resistance; they are very accurate, up to 0.001 mOhms being a battery or not. And there are plenty on aliexpress
Came here to say the same thing. I use RC3563. You can also measure capacitor ESR. However, both ESR and internal resistance measurements aren't as accurate as measuring under load.
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
@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
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
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)
At the beginning of electrification, homes often only had electric lighting, but over time various electrical devices began to appear, such as radios, record players, irons, and vacuum cleaners, so out of need, splitters appeared that allowed for connecting not only a light bulb but also, for example, 2 other devices.
3:53 Where you using high speed mode? That steps up the frequency ceiling but at a cost of battery longevity. This scope has opened up a whole new world for me, as someone returning to the hobby on an extremely tight budget. Addendum: I would love to see you do a tutorial on scopes like this for the beginner because I really appreciate your teaching style. Back in the 80s when I started, oscilloscopes where far outside my reach. And now that I'm returning to the hobby, I am learning to use them from scratch.
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.
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.
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!
I bought a laser path finder yesterday for my dad for Christmas… I never knew these existed Thanks Scott… I think you should have one video per week at least ❤
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.
@@AK90I have one and it’s the greatest thing since sliced bread. I like to travel as light as possible to jobs and mainly only need a multimeter but a situation comes up every now and then where an oscilloscope is useful and this meter just makes that simple. Just the fact that it’s USB C rechargeable already makes it better than my regular multimeters.
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)
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
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.
You could get a YR1030 / 1035 - Its meant for measuring the internal resistance of Batteries and can go down to 0.01 mOhm but its perfectly fine for measuring any resistance ofc.
@@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.
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!
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.
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.
Using light fittings as a socket was a life saver many times when travelling in India, where a lot of the cheaper hotel rooms have no sockets at all. The only way to recharge batteries.
For everyone commenting about the bulb socket, I don’t believe he was criticizing the idea itself. He was saying the specific one he got was not well made and does not meet modern safety standards. There could certainly be versions that are built much better, and models that are sold locally in stores should meet modern safety standards in your area. I believe his advice is that you should be more careful buying such products from AliExpress because they do not have to adhere to the same safety standards. If anyone has taken apart an LED bulb, the build quailty seems very similar. Most LED bulbs use less than an amp of current, thus the internal wiring and connections do not need to be strong. The connections inside such a bulb socket should be crimped and use thicker guage wiring.
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 use one of the light socket adapters every Christmas for my outdoor Christmas lights. I don't go all Griswold with my lights, just a couple of strings, probably less than 50W total. The adapter is very handy as the light above my basement door is already on a timed switch allowing automation of my Christmas lights with basically zero setup. I would never use it for anything else however as regardless of the current rating of the adapter I'd imagine the current rating of the wiring in many light fixtures isn't designed for much more than the maximum bulb wattage listed on the fixture.
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.
I use a US version of the light socket to receptacle adapter to test wiring, I can plug in a recept tester if it reads open ground it's good, continuity tests are just easier with a receptacle then a socket, I can set my plug tester to tone and find a breaker by sound... just stuff like that.
In some countries long ago there were different prices for electricity used for light than other things. Adapters like these were used to cheat the system. I believe, but I'm not sure, France were one of these counties.
I have a not-sketchy light bulb adapter similar to that, but it has 2 wall outlets in addition to a bulb holder. My use case is... lighting. My garage has only a single bare bulb, and the outlet is rated for 150W. So I bought 4 strings of LED shop lights, which use about 40W each, and a 30W LED bulb. My garage is plenty bright now.
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.
When I was younger it was common to see a device that went between the bulb and the socket with an outlet on each side. That way you could plug in two appliances and still have light!!!
This E27 socket adapter is sometimes very useful; for example, if you need to use some tools in the ceiling and it is hard to pull an extension cord up there. Nowadays, it is becoming pretty useless, though, because most light fixtures are now LEDs and no longer use the E27 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
Found a USB with adjustable Voltage output 1-20V or something. Hidden gem for me, love it. Maybe for the next video if you have not yet had a look at it.
I've been using light socket to power outlet adapters my whole life. For example, I replaced all my incandescent bulbs in the basement with cheap LED shop lights. I used the adapter since those sockets are already controlled by the light switch.
Back in the old analog days most meters had a zero button where you would connect the leads together and zero the meter. Just like your device. This feature alone would be good enough for most meters today. Just like weighing things with the tare button.
We have been using those adapters for almost 100 years. Typically used in older homes where there were no outlets aplenty as we are blessed with now...
The socket is mostly sold for people who want to steal electricity from common areas... like charging a bike in a basement without a socket in an apartment complex.
the iPhone has a magnifier accessibility feature that works surprisingly well for what you were trying to do with the last gadget. I assume android would have one too.
I bought several small tubes of that exact brand "liquid" tape. Mine came out of the tube just the same. I've found that it's certainly NOT like the liquid tape I'm used to that has the brush in the can. If I ooze some out onto {whatever}, then form it into place with my fingers and leave it... it then cures up. It's almost like using playdough!
That angle grinder adapter is a ridiculously useful thing. I had it, and a "pipe sander" adapter at work, but when trying to buy one for home use i only encountered cheap knockoffs (scott here however found an even worse one... it definitely shouldnt be made with plastic). If you get a proper one, it will be your favorite tool.
I've made my own adapter like that in my storage unit in the basement of my apartment. There's no power down there other than a lamp and I needed power for my security system running on an ESP32. Works like a charm (but mine also allows me to use a bulb.
The socket outlet is useful if you have vanity lighting in the bathroom as well as inconveniently placed and/or few outlets. Removing 1 of 3 to 6 lights is going to have a minimal affect.
@@A_Retired_MSgt common sense doesn't help you if there is a fault in an appliance you use.... Even less in a bathroom where you stand barefoot and have plenty grounded things to touch
Had the same issue with the 'liquid' electrical tape. Bought a small metal can and it was already hard. Really strange that it had a 4.6 rating. There is 1 thing that we still need that I haven't found yet. A sort of shrinking tube that you can pull over an already soldered wire, or were the isolation is damaged, and that closes as you shrink it. It would replace this mess of a liquid tape. Btw I have the previous version of the scope. Very good stuff and there is a 18650 in a batt holder so you can replace it with a better one.
i saw someone use one of those lightbulb outlet adapters at a subway once, was kinda wild, dude just walked in, stood on a chair and unscrewed the bulb, screwed the adapter in and just plugged in his laptop
I actually had a use case for that lightbulb socket adapter! Years ago, my bed reading wall light had a GU10 incandescent bulb; I wanted to upgrade to a LED bulb since it was getting so hot to actually be uncomfortable to use. GU10 LEDs were painfully hard to find and overpriced in my area back then, and I couldn't replace the reading light since I was renting. I used one of these adapters to plug in a LED kids night light. Problem solved!
You used the wrong type of sandpaper. Red sandpaper is for soft materials, like wood or plastic. For metal you need the blue type (zirconium sandpaper) or even better ceramic alumina sandpaper. Red sandpaper is aluminum oxide and also pretty bad if you're using it on metal before welding, as it leaves deposits of aluminum oxide on the metal which can weaken your welds - apart from being used up pretty quickly that is.
As for the adapter. A friend of mine needed to fit a wifi repeater in his storage box to reach his ev charger in the common appartment garage. Only available thing was a light point.
I'm interested in the "digital microscope" to examine the apex on blade edges. Might have to get one to see if it can take the neck-breaking out of using a jeweler's loupe.
I have OWON HDS272S, multimeter plus oscilloscope (it can measure two signals at once up to 70MHz)+ signal generator, bought for around 120 euros from banggood. Super good (just one flaw - low current range does have high resistance, but 10A range is so precise it can measure even 1mA, making low current range totally worthless.
7:40 there's a similar board on Amazon by Walfront w/ 8 relays, esp32, & i/o header vias. Works great w/ Tasmota (for HA). Only supports 5-30VDC for power, but that works fine in my camper.
Hehe recently bought the same microscope for the same reason and had the same realization xD if this thing had autofocus and could focus on distant objects it would be awesome. So it's just a nice science toy for my daughter 😅 great series, keep 'em coming ;)
ESP Home Automation Board looks promising, I was looking for something like that for a while :) As for the oscilloscope - there are also other similar scopes like OWON, they have a built in generator with BNC output, also simple but a bit more configurable than that in ZOYI scope. It's worth mentioning that these scopes have common ground (even with the USB port), so watch out with your measurements while charging or connecting it to the PC :)
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.
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.

The oscilloscope is quite good. I'm watching a small youtuber that does electronic automotive repairs and he uses it all the time
Back in the old analog days most meters had a zero button where you would connect the leads together and zero the meter. Just like your device. This feature alone would be good enough for most meters today. Just like weighing things with the tare button.
Holy SHIT! I need that 3in1 Multimeter! Its only missing 1 function for me, the ability to connect a temperature probe.
Maybe in the next version ;-)
5:11 we use these at work alot. They are handy when working in certain houses.
I’m intrigued by the apparent auto dubbing from German to English, for the American viewers, this is amazing.
I like this series! Please keep making them.
We have been using those adapters for almost 100 years. Typically used in older homes where there were no outlets aplenty as we are blessed with now...
The socket is mostly sold for people who want to steal electricity from common areas... like charging a bike in a basement without a socket in an apartment complex.
the iPhone has a magnifier accessibility feature that works surprisingly well for what you were trying to do with the last gadget. I assume android would have one too.
Those sockets are actually useful in some hotel room where you didn't have sockets into the walls....
I bought several small tubes of that exact brand "liquid" tape. Mine came out of the tube just the same. I've found that it's certainly NOT like the liquid tape I'm used to that has the brush in the can. If I ooze some out onto {whatever}, then form it into place with my fingers and leave it... it then cures up. It's almost like using playdough!
Not okay for UK
That angle grinder adapter is a ridiculously useful thing. I had it, and a "pipe sander" adapter at work, but when trying to buy one for home use i only encountered cheap knockoffs (scott here however found an even worse one... it definitely shouldnt be made with plastic). If you get a proper one, it will be your favorite tool.
Wall to socket adapter is actually usefull. Eg. in mountain shelters there are lights, but sometimes there is not(enough) sockets.
I've made my own adapter like that in my storage unit in the basement of my apartment. There's no power down there other than a lamp and I needed power for my security system running on an ESP32. Works like a charm (but mine also allows me to use a bulb.
The socket outlet is useful if you have vanity lighting in the bathroom as well as inconveniently placed and/or few outlets. Removing 1 of 3 to 6 lights is going to have a minimal affect.
Sounds super usafe since it does not have earth or grounding
@NinoJoel depends on what you're using for and how your bathroom is set up. Common sense should be enough to keep someone safe.
@@A_Retired_MSgt common sense doesn't help you if there is a fault in an appliance you use....
Even less in a bathroom where you stand barefoot and have plenty grounded things to touch
i think the reviews for the light socket adapter are so high because if u need it, it is so simple that it just does its job.
Portable oscilloscope is a great find. Video suggestion is to compare many sub 100euro oscilloscopes like those DSO138, Fnirsi, Aneng and alike
Had the same issue with the 'liquid' electrical tape. Bought a small metal can and it was already hard. Really strange that it had a 4.6 rating. There is 1 thing that we still need that I haven't found yet. A sort of shrinking tube that you can pull over an already soldered wire, or were the isolation is damaged, and that closes as you shrink it. It would replace this mess of a liquid tape.
Btw I have the previous version of the scope. Very good stuff and there is a 18650 in a batt holder so you can replace it with a better one.
i saw someone use one of those lightbulb outlet adapters at a subway once, was kinda wild, dude just walked in, stood on a chair and unscrewed the bulb, screwed the adapter in and just plugged in his laptop
As usual, great content! Thanks again!
My pleasure!
Well light outlets came before wall-sockets, so this was pretty much used way back.
I actually had a use case for that lightbulb socket adapter! Years ago, my bed reading wall light had a GU10 incandescent bulb; I wanted to upgrade to a LED bulb since it was getting so hot to actually be uncomfortable to use. GU10 LEDs were painfully hard to find and overpriced in my area back then, and I couldn't replace the reading light since I was renting. I used one of these adapters to plug in a LED kids night light. Problem solved!
Buy another tube of liquid electrical tape. This stuff is super handy!
Hmmmmm......
@greatscottlab maybe from a better brand
4:55 this is very cool. I am pretty sure that there is an FPGA in there
Nice, the multimeter-scope combo might find it's way in to my toolbox. Thank you for this series!
For low resistance measurements, I use FNIRSI HRM-10
very affordable and super useful
You used the wrong type of sandpaper. Red sandpaper is for soft materials, like wood or plastic. For metal you need the blue type (zirconium sandpaper) or even better ceramic alumina sandpaper.
Red sandpaper is aluminum oxide and also pretty bad if you're using it on metal before welding, as it leaves deposits of aluminum oxide on the metal which can weaken your welds - apart from being used up pretty quickly that is.
I love this series!
As a electrical engineering student ,I thought I would never hear,, e27 to socket adapter"
As for the adapter. A friend of mine needed to fit a wifi repeater in his storage box to reach his ev charger in the common appartment garage. Only available thing was a light point.
You can get those light socket outlets in Wal-Mart and hardware stores here in the US
Oh boy. Hopefully a bit safer design.
I'm interested in the "digital microscope" to examine the apex on blade edges. Might have to get one to see if it can take the neck-breaking out of using a jeweler's loupe.
The bulb sockets have been around since the 60s 70s nothing new there :
)
Never said that though
Any electrical tape can be a liquid with enough current.
I have OWON HDS272S, multimeter plus oscilloscope (it can measure two signals at once up to 70MHz)+ signal generator, bought for around 120 euros from banggood. Super good (just one flaw - low current range does have high resistance, but 10A range is so precise it can measure even 1mA, making low current range totally worthless.
7:40 there's a similar board on Amazon by Walfront w/ 8 relays, esp32, & i/o header vias. Works great w/ Tasmota (for HA). Only supports 5-30VDC for power, but that works fine in my camper.
Get some bison liquid rubber at your local hardware store. Ive used it in a few battery projects that needed a water seal
Now im fighting the urge to spend money on Santa PCBs
Go for it ;-)
The socket adapter could be used in a closet that has only a light fixture.
Hehe recently bought the same microscope for the same reason and had the same realization xD if this thing had autofocus and could focus on distant objects it would be awesome. So it's just a nice science toy for my daughter 😅 great series, keep 'em coming ;)
Didn't take them long to bump up the 75 euro scope to 105 euro (your link).
ESP Home Automation Board looks promising, I was looking for something like that for a while :) As for the oscilloscope - there are also other similar scopes like OWON, they have a built in generator with BNC output, also simple but a bit more configurable than that in ZOYI scope. It's worth mentioning that these scopes have common ground (even with the USB port), so watch out with your measurements while charging or connecting it to the PC :)
Chinese sockets are often rated for 20A
I actually use one of those light bulb adapters 😂 it feeds a led strip power supply and his hidden under the light cover.
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.
