Doorbell Q&A (Yes really)

[@MartinWillett]

This video is a great demonstration of what it takes to be a KZbin star. Hard work, technical expertise, good hardware, a voice which is pleasant to hear, a sense of humour and an ego which is under control. The editing here was complicated, mixing in stills and video, but it all seems to happen effortlessly. If anyone has got half a mind to make some stuff for KZbin watch Techmoan. It takes more than half a mind to do it well.

[@ingvarhallstrom2306]

Agreed. A Q&A about doorbells shouldn't be this fun, it takes someone raised on Douglas Adams to make it so...

[@remo687]

I always make sure that every one of my devices has a durable all-weather technological and only the highest-quality stableable.

[@Wildmutationblu]

Only Technoman hehe could create an amusing laugh out loud q&a about a doorbell.

[@karthick86c]

Man I knew you had a bit of humor but never thought you could dial to a 10! I am in stitches!

[@hikaru-live]

Here is some technical aspects: the button contains a STMicroelectronics STM8S003 microcontroller and a Texas Instruments CC115L 433MHz low power radio transmitter. The receiver have a matching radio receiver, decoder and music playback circuit. When the button is pressed, the button mechanism actually functions as a generator to power the transmitter circuitry using the energy from your finger pressing it. It then sends out a broadcast including some kind of identifier code. The receiver listens to that frequency, check if it have received a code that it recognizes, and rings the bell when it have picked up a code it should respond to. The pairing process allows the receiver to know what code(s) it should resond to.

They just gave a posthumous award to the guy who invented door knockers. Yes,they gave him The No-Bell Prize.

[@PXKMProductionsGaming]

This video was sooo funny! The "followeing" part really got me and I played that line many times. Great job!

[@beebeer]

Your presentation and humour is excellent.

[@a1d3nh0]

Your Britishness is brilliant. Your sarcasm and your very British insults at the haters. THATS why I love your channel. PS, I'm English

[@donaldasayers]

Very useful video. I bought one as a result of your first video, but recently it stopped working on our bell push and started going off at random. Now thanks to a screenshot of the instructions (which I had lost) off your video I have been able to re bind it to our bell push. Thanks.

[@MobiusVideo]

That bit at the end really made me laugh and brightened up my day! I never imagined a video about a doorbell would...um...push my buttons? Terrible pun! Thanks for uploading :)

[@rustinpieces]

"Woman with an apple-gag"... "That's Jesus at your door"... Man, you're priceless. :-)

Howling with laughter here. I saw John Cooper Clarke's standup show a few years ago, let me tell you I didn't laugh half as much as I did when watching your doorbell Q&A Video 😆

[@sgtgrash]

+Alexander Cavendish Simson Same here... Could someone please pick me up off the floor XD

[@ChipGuy]

Thanks for the detailled photos, they look really nice. I can see from them that the door button consists of a ST-Micro brand "STM8" microcontroller and a Texas Instruments CC115L "Value Line Transmitter" They actually don't need to use different frequencies but they use unique codes for each button. The transmitter can easily transmit 4 bytes in basically no time, that would make 4 billion codes. The 4 pads near the microcontroller are most likely the contacts they use during production to program that unique number into the chip. I can see a red limiting diode, a rectifier black diode and the yellow capacitor used to store the charge from the button push. Also a little chip with inductor to convert the voltage of the coil into something stable that can be used by the 2 main components. Very neat design.

[@MaxKoschuh]

+Chip Guy Vids excellent comment

[@AttitudeGames]

+Techmoan Those door bells use the same frequency between sets, the only difference between them is their code that they transmit, and its that code that you are telling the receiver to learn when you pair them up.

[@Allan_aka_RocKITEman]

"...there's no way in hell I'm going to answer that door." *LMAO!!!*

[@fordtechchris]

I cannot remember when i last laughed so hard!

[@TheBrokenLife]

I saw the title of the video and gave a chuckle... Then I watched the whole thing. LOL!!! If they could all be this good, you should become the doorbell review channel.

[@thecorbies]

Hi Matt. For the avoidance of any confusingness (Banggood speak). I didn't ask any questions about this item, but I WAS laughing out loud when you started the part about the Banggood info. Totally excellent video - thanks. Regards Mark in the UK

[@hyperplastic]

I'm crying of laughter after the last part...!

[@uriituw]

This was worth is for the promotional material alone!

[@succuvamp_anna]

I think the company does the funny advertising because they know how boring the subject is. Great video as always 😊

[@bami2]

433,92 MHz is a pretty popular frequency for random wireless domestic things. You have these wireless utility switches/relays that work on the same principle: when you press a button it first sends a code, and then the state. The receiver just continuously listens and when it gets a signal, it compares the code to the one programmed into the device (or set at a later date) and then executes its function. I have my home full of these wireless transmitters and receivers, and with a transceiver connected to a server (for example rfxcom) I can switch lights and other things on/off via the internet, program them on timetables and all kinds of fun stuff. Sure the security is negligible (since it's just a code that is being sent that anyone can pickup), but it makes for a fun home-automation project.

[@Dazzwidd]

I swear now after watching many of your videos, that you have either been involved in broadcasting or production of some sort. No complaints about that, it would just testify as to the calibre of the videos you put on KZbin. Anyway, on the bell push generator, it's just an electromagnetic generator, but it's interesting that it can power that much electronics with such a short duration of power generation :) lots of windings in the generator coil I guess. Perhaps they're down converting a highish voltage spike to a lower voltage but more current. Hmmm...

[@lammjame]

That last bit was hilarious. Please read more promotional materials and manuals for us.

[@tobyaman7644]

Mat you always know I love your videos but this is my fav so far, absolutely brilliant. Cheers Rob

[@Andy-Robus]

I love watching your videos on KZbin. they are so polished, I like the accent, and the clear filming and the banter and jokes. have you ever been a DJ or a voiceover guy? your voice reminds me of one of those smashy and nicey characters from the 80's radio station DJs.. and I mean that in a nice way. lettts rock! :-)

[@Techmoan]

+Andy Robus no, nothing like that, I'm just your plain old average chap.

So they are not only masters of the doorbell but also masters of comedy. Sold!

[@waspoza]

Gotta love British sense of humor. :) +sub

[@PEK-97]

"Copying water gauge" is actually a Chinese joke as the manufacture is Chinese. Basically in China every end of month there will be a guy from the water supply company going to your house copying the water gauge readout and determining how much you have to pay for your water.

[@roceb5009]

shuo feng we have a similar setup here in the States, but we would say the guy from the water company comes around to *read* your water meter not *copy* it. If he copied it, that would mean like he really likes yours, so he makes one just like it for himself. Also, it still doesn't make sense. Why does he have to knock on your door, why doesn't he just walk up to the meter? Is he trying to supplement his income by selling cosmetics door to door or something?

[@lollandster]

They are probably using the same frequency, but the sender unit sends a unique code that the receiver ignores if it's not in the list of known sender units.

[@JPilot2]

Techmoan, thank you very kindly for the marvelous humor!! Cheers! :-)

[@crapper1]

rofl one night stands yup need 40 ringers for that situation

[@mikeselectricstuff]

The bellpush doesn't look very rainproof. The generator is magnetic, not piezoelectric. EnOcean invented something very similar a few years ago for similar applications- this looks very similar. Google ECO 200 for their version.

[@grizzly6699]

Great comedy there Mat. A much needed laugh.

[@pierrec1590]

Chances are they are all working on the same radio frequency, but transmit a binary code that is stored in the flash memory of one of the units. It is trivial to generate a random number that will give the individual units a very low probability of being repeated in the same neighbourhood.

[@hikaru-live]

You can just grab a RTL-SDR, optionally with a low-noise amplifier add-on, and listen on the frequency the CC115L chip generates. You would get a list of codes after a few days of monitoring the airwaves. Now you can build your own transmitter using the same CC115L chip, but with a RF power amplifier and some way to attach either a computer or a user interface added on it (can be as simple as a USB microcontroller like ATmega16U2 or STM32F042.) Now you can annoy your neighbours by ringing their bells without going near their houses.

[@klauspetersen8593]

Makes sense however I think they would just assign them an incremental id number or one of a predetermined set of random numbers during the programming stage of the production. Many ways to do it, but a completely random number would sooner or later cause two bells having the same id number.

[@wormyguy]

Klaus Petersen en.wikipedia.org/wiki/Universally_unique_identifier

[@zaprodk]

I waited for this video and it's here - Great! - Technically, it's still the same frequency - It just changes the code that is sent. The two chips in the product is a "16 MHz STM8S Microprocessor" and a "CC115L cost optimized sub-1 GHz RF transmitter" - The transmitter chip can be programmed for different frequencies for different parts of the world where the regulations differ a bit. I'm pretty sure that yours are operating in the 433-MHz ISM-band. I'm really glad that you showed the '"generator" as this bit interests me a lot. Quite interesting to see a coil and magnet in stead of a piezo-element!

[@peterpv0001]

Actually, they all do use the same frequency (see the manual !) the code they send (it's just a sequence of pulses) makes the receiver able to distinguish your doorbell from the neighbour's ! Your sense of humour is typically British, I like it :-)

[@azyfloof]

I think I enjoyed this more than original video :D I love you, for the namedrop of sorts, and the REM reference :P

[@roboyle]

Feedback: I found the second half of your video to be much more informative than the first. Great stuff! :)

[@JanBabiuchHall]

Honestly, one of my favorite videos of yours thus far. And I'm fairly certain I've watched damn near all of them. That big coil makes me think it's actually just a regular induction-based generator, not a fancy piezo setup. Still though, could really use +bigclivedotcom 's help in interpreting the exact principles of operation.

[@dannoffs]

You should send it to eevblog to do a teardown!

[@benmauro1022]

that is the beat doorbell ad I've ever seen, stableable? yes please.

[@MattTester]

Although that power generation tech isn't new or particularly special I've never seen it used like this before so I'm actually quite impressed and appreciate the closer look, I can think of many other applications where not having to worry about the batteries would be more than welcome. Not that it really bothers me but I expect that the generator is actually less damaging to the environment than just one battery (based on materials) too.

[@Techmoan]

+Matt Tester (UKMatt2000) I still think it's pretty clever that a press of a finger can translate into electricity that then powers a wireless transmitter. Now all I need is a car that I can power with rapid clicks like I was playing hypersports.

[@mukiex4413]

And with this commentary, I realize that every internal thought I have watching stuff on KZbin probably makes it into the comments field in the most obnoxious way possible from someone else. I suppose if I was gonna complain, I'd first cover the dust in some shots, but I know first-hand that removing dust from black surfaces for a photo shoot is a bloody nightmare.
