Inside a voice controlled light - with schematic
HTML-код
- Опубликовано: 29 июн 2024
- I didn't realise how far voice recognition had progressed. This light can understand several voice commands and react accordingly with no need for a network connection.
One slight correction. A longer test showed that the unit does not store the current state to flash memory, but will power up in a random state if left off for a while.
I couldn't identify the chip, which isn't surprising. It's not the sort of thing the manufacturer would expect hobbyists to use.
I'll guess that it's probably looking for key sounds. I used to have a crude voice recognition toy when I was younger, that asked questions and could recognise just two words - yes and no. Some experimentation showed that it really just recognised the "S" of yes and the "O" of no. Two distinct sounds that can be easily differentiated with simple filters.
The commands that this light recognises are:-
Turn on the light.
Turn off the light.
Change the colour.
Dim the light.
Brighten the light.
The (undocumented) dimming has five steps, and the light flashes once to indicate that it has reached the dimming limit in either direction.
The unit can be operated from a significant distance away, but is really intended for close use.
Current draw is about 300mA lit and 10mA in standby.
Sorry conspiracists - the unit can NOT listen in to your home and send your conversations to the Chinese government.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.com/coffee.htm
This also keeps the channel independent of RUclips's algorithm quirks, allowing it to be a bit more dangerous and naughty.

If I were writing code for a product like that, I'd add a hidden function triggered by "One moment please" to flash a message in Morse code.
SOS
*. . . - - - . . .*
.--. . -. .. ...
Or perhaps sets the device to a special "Clive Mode" that randomly keeps changing the functions of the pins to keep clive reverse engineering longer.
@@GruffSillyGoat That would be an expensive chip indeed lol
The fact that there are at least some undocumented voice commands would fascinate me. I would probably spend an embarrassing amount of time saying everything I could imagine a light doing, phrased in every possible way, just to see if I could get this thing to do something new.
I wonder whether it responds to similar commands spoken in Mandarin or Cantonese…
@@markiangooleywas wondering about that also, you'd think they might at least make a Spanish or French version.
I spent a lot of time testing commands.
There are language specific versions.
i have a vocabulary sheet that came with mine - see comment, above.
Not going to lie I definitely thought this was a fake, troll video at first with how flawlessly it worked on those voice commands. Pretty incredible for a cheap, one chip solution!
I'm surprised how good it is.
That could put Amazon and Siri out of business in one fell swoop, eh?😂 🤣
Rossmann also has released an Android keyboard that also has a pretty good offline voice recognition.
Especially with a UK accent. Eg RUclips auto captions usually make a hash of Clive.
@@Gengh13Offline voice recognition isn't hard at all when you're running on a full-blown ARM SOC in a smartphone. This is a completely different situation
This is much more reliable that those voice asistents that have serious hearing problems and require internet connection to work at all.
Alexa hater? 🤣 But Clive's light can't ... tell you the weather, spell and define words, perform calculations, change channels and adjust TV volume, turn the lights and appliances on and off, make free telephone calls, set reminders and alarms, play the radio, play nature sounds at night, and a million and one other things too!
@@marcse7en If only it could do those in a way that was more convenient than me doing it myself. I went through a phase where I had an echo in every room, controlling all my lights and whatnot, then over time they began to become terrible at understanding what I was saying making them a pain to use to even control something basic like the lights. So I went back to buttons to turn my stuff on and off. Only difference being is that they are wireless buttons near where I sit instead of on the wall.
@@marcse7en Imagine voluntarily installing a monitoring device into your own home. Blows my mind how daft people are.
@@ferrumignis Your attempt to insult aside, I couldn't agree more! ... But for different reasons! ... Oh, and STOP being such a bloody paranoid luddite! I've heard this pathetic argument before! It's highly ignorant, and is wearing VERY thin!
@@Hyperion62 That is certainly NOT my experience! ... Perhaps you're not enunciating properly? 🤣 ... Still, if you're a luddite who prefers to live in a damp cave?
Fun fact: JieLi part markings have the part number at the end after the dash, being the tail of the part number. The chip in question is AC6969D4. You can try using LCSC's JieLi listings for reference.
That's a lot of power for a $5 usb light.... wow!
Nice nice 😂
Wow! It's WILD how capable that little chip is! Full on DSP chip.. Very cool.
It's basically a repurposed Bluetooth speaker chip. It's honestly amazing how they can make something like this work. I have a chinese version with a RGB LED and while it gets incredibly boring after a while, the voice commands works shockingly well. Just annoying how these JL chips are really hard to mess with.
It would be cool if some the functionality could be accessed. I see it’s got Bluetooth, USB, charge controller and other stuff in the AC6969D4 version. Dang!, that’s a lot of compute power in one chip for less than 50 cents US.
I found what appears to be the same USB light for sale on the Walmart Marketplace web site for 5.96 Dollars US, free shipping, before sales tax. I ordered a few for experimentation.
The fact that you hadn't had to repeat yourself is amazing all on itself.
it is remarkable that voice recognition is now cheaper to process than a mechanical on-off switch! 🤩 i found a similar such unit in a smaller package - a Tech1 USB Intelligent Voice Light. it may be useful for you to know that there are several more voice commands:
Turn On
Turn Off
Light on
Light off
Go to bed //some sort of sleep timer
Brighten the light
Dim the light
Maximum Brightness
Minimum Brightness
Set one hour timer
Set two hour timer
Cancel timer
Red colour
White colour
Blue colour
Green colour
Pink colour
Purple colour
Yellow colour
Change colour
got it at Dollarama in Toronto, Immported from China.
very cool little bit of tech. thx for your teardown. 👾
It even understands UK spelling. 🙃
What does "change colour" do on yours? If it just cycles between the three whites it might be that this chip is exactly the same. Time to probe unused pins to see which are the outputs for the other colours. But it would be trivial to, say, ground a pin to put it into multi-colour mode, and that would require more experimentation.
clive , i'm truly impressed with today's thing. is it worth considering a review of this toronto dollarama version too?
Clive tries "Flash SOS", followed by a long screamed "Noooooooo".
I bet this would be REALLY cool in one of the LED headlamps! Wouldn't even need the IR motion detection feature, could keep working with both hands and just tell the flashlight what to do.
And no SOS!
Yeah, I agree. It’s always a pain when using the headtorch for some job involving dirty/oily hands, then you have to fiddle around with your head torch to turn on/off/dim.
The colour change could also be repurposed for a near/far option, depending on whether you need to see something in the distance or read something small
ez, get that headlamp with the USB in the front and stick this into it big clive did a video on it a while ago :p
@@sam.p12345 Whats a head torch
What a time to be alive! All that functionality for under £5!
Dead people: "What a time to be dead! All that functionality, and I've no money!" 😭
Something like this would have been good for my 85 year old grandmother.
Mine too, the ⚰️ is pretty dark.
From the datasheet it looks like that really is a multipurpose chip. Nice work Clive.
If you found the datasheet, can you share for all of us to find?
@@jouneymanwizard The chip is AC6969D4.
That's fantastic and absolutely futuristic. I want one. Google search coming. ❤
I wonder how it would respond to: Open the pod bay doors, HAL...
It doesn't have a lip-reading camera. Or does it? Probably calls home to the Chinese government every 2 seconds, anyway...
@@MrMesosphericno, that's only what it does when you say "call home".
I remember my dad struggling with voice control car headset modules in the early 2000s. You'd have to train it to your voice, and then he'd sit there struggling saying "Call home. Call. Home. CALL HOME."
All a bit ironic, given that most dads want to 'escape home'. 😂
And then it would call the plumber or something. Fun times.
IIRC those did basically waveform matching. And youd program it in the garage, nice and quiet, but end up using it on the road. With all the road noise, electrical noise usually found in a cars electrical system, vibration through the cars body. Designed by people who only test it in sterile laboratory conditions, or carefully choreographed trials, never in the real world much less testing it to failure or backwards from a point of failure to where it starts working again to define its operating window.
The sad part is far to many STEM kids who just followed instructables all their lives are designing 'smart' cars now and doing the exact same tests....as in barely any at all. Certainly not any that stress test their control systems.....remember that next time you see a tesla or self driving taxi on the road......
Ever tried the speech commands in a recent Volkswagen? they do not work a tad better than that, at all.
@@alexanderkupke920 Haha, you beat me too it. My mates brand new BMW is either deaf or retarded also.
He asked it to navigate home and it started directing us to some random place in rural France 😂
I did a bit of searching and the chip appears to be (based on the appropriate section of the manufacturers website) an AD142A4 by ZhuHai JieLi Technology, although looking at the datasheet it appears to be a general purpose MCU for kids toys, so I guess they have an application specific voice library that can be loaded onto it.
It's actually a JieLi AC6969D4
It needs a "Initiate Self-destruct sequence" command!
Self-destruct? At £4.99 a pop? ... Are you insane??? 🤣
But must also have the spoken response of 'Self-destruction will commence in [x] minutes', repeated every 60 seconds. KABOOOOM!
Not necessary, this occurs automatically, a few days after the warranty expires.
@@marcse7en sorry Dave i cannot do that
It need a "let's play global thermonuclear war" command! 🤣
It is absolutely stunning that such a complex algorithm as speech recognition and control can be crammed into a small cheap processor, and on top of it all work quite well too. Very impressive and very futuristic indeed.
Note that it's for a USB power supply not battery power?
Welcome to the age of the microprocessor! (They've been around a while, so it's small wonder they've evolved?)
It's not using true speech recognition it's using carefully chosen commands and working of the length of sounds and number of gaps between them.
It wasn't that long ago you spent hours training Dragon Dictate to have it not work very well, and here's a piece of tat that even works with a Scottish accent.
That's just amazing.
@@j.f.christ8421 Big Clive's NOT offended by your comment! 🤣
It probably does the dim light thing instead of saving the 'off' setting so that you don't think it's dead (or there's no power) when you next plug it back in
Agreed, coming back on at the dimmest setting is intentional … and clever!
Imagine the electronics 20 years from now.
I look forward to seeing them, when I'm 82! 🤣
Apparently this is a general DSP mainly intended as bluetooth speaker IC, supports BT and usb otg as well. No ingrained voice commands, so its all done in code.
This seems unlikely. Zuhai Jie Li do make bluetooth speaker ICs that are widely used in the lower cost speakers, but they also make a range of dedicated voice recognition ICs for light control.
@@ferrumignis the part number ac6969d4 comes back to an ic that says intended application is Bluetooth speaker. Do you have a different part number that says different?
What, it doesn’t come in pink? 😂
I love it. Minimalist to a fault. No remote, no internet connection, not even Bluetooth. It “just works”.
One of the things that really impressed me was that the tiny microphone responded very well to your relatively deep voice. Yours is only a bit deeper than mine and I’ve had trouble with voice controlled electronics understanding me. Whoever designed that thing, particularly the software, is very good at their craft.
The irony is the chip running the lamp is a repurposed Bluetooth speaker processor. … De-contented for the good of mankind. 😊
I haven't noticed lack of lower frequencies when listening to recordings made with tiny mics. Possibly as part of the algorithm to make it more robust, it digitally filters out frequencies below the level where it expects voices to be. Poor Lee Marvin wouldn't be able to control his lights. 🌠
@@wtmayhew I guess that explains all the unused pins…
@@matthewmarks6951 Are your mics of the same (presumably low) quality as that in the light? Granted the device is overall pretty good, I can’t bring myself to believe that the maker splurged on the mic.
@@markfergerson2145 Considering how tiny the mics are in phones and the quality you get from them, I would be surprised if there was a noticeable cost saving in making a mic that worked worse. They are very simple devices.
Last time I was this early, the dinosaurs were walking the earth. Thanks clive for the amazing videos!
Yup, harder to find one walking these days now that the dinosaurs have learnt to fly
I just bought one of these halfway through! You are an influencer Big Clive! 😂
Where did you find one?
@@Hazzard2theworld911 I guess the price has risen exponentially by now!
@@Hazzard2theworld911 I found one on Amazon, which looked identical…. But who knows what may arrive!
I used to think voice control would need to be processed by a pretty powerful computer or server to be good, but this cheap single chip working flawlessly really changed my world view. The idea of smart devices that dont need the internet or a phone to work is super cool to me!
A guy at college in 1978/79 had a voice controlled motor final year project. It was based around a transient recorder and an 8 bit microprocessor. I would hear him at the other end of the project bays saying "start", "s....tart", "st...art" for hours with nothing happening. His project tutor came along and said "start" and I heard the motor spin up. He said "stop" and it stopped. The tutor was Scottish with a strong accent. It transpired that the only way to voice control the motor was to adopt a strong Scottish accent. It worked every time.
I think, you can also use "brighten a little" and "darken a little" and "lighten up" for the dim function. "I'm back" and "Come back" to switch the light on and "I'm out", and "I want to sleep" to switch it off. Curtesy the store of the of the "fast delivering (Chinese) ant".
Back in the late 1970's early 1980s I had a toy sold as voice recognition but what it did was count the pauses in words and phrases. It was robot so things like FORWARD and GO BACKWARD, TURN TO THE RIGHT and so on. Then there was the Robot Commando sold back in the 1960s that had a remote voice command function that was just a magnetic breath paddle switch. They had to change the box text and instruction after the first run of the toy for legal reason.
I'm impressed the voice commands actually work. I have a clock with "voice activated" on its feature list and it's literally a clapper that turns up the display if you yell at it loud enough
I don't need one, but I sure want one.
@1:43 - What a clever little device! Partly due to the autonomy from the internet and partly because it's kind of cool!
I remember a star trek voice controller from the late 90s or early 2000s. You plugged it in and plugged something into it. You said, computer. Waited for the prompt and then said lights. You could even give it a percentage.
In the early/mid 1990s, my brothers and I had a Buddy L "voice command" branded toy fire engine. It had a surprisingly large set of commands (for sounding the horn, engine start, lights/sirens and driving forward at the very least) and actually worked quite well. (It would also at least try to interpret totally off the wall commands.) There was also a set of recorded instructions available by pressing a button. There was also another button that started it listening for a command. Despite having been very curious about how it worked and what kind of processor it used, I never took it apart.
I have seen one of those "JL" branded ICs in an MP3 player and FM radio. I believe it was marked "AC1220". The FM radio tuning part was handled by another IC. It had at least one undocumented feature, in that it could play uncompressed PCM audio.
Impressive functionality at such a low cost!
It's got better speech recognition than those automated phone robots you get when you call for customer support... "Main menu... MAIN MENU... speak with agent... SPEAK WITH AGENT... NO... SPEAK WITH AGENT... AAARGH!!!!!"
"SPEAK WITH AGENT"
_"You wish to end the call, is this correct?"_
"NO!"
_"I heard yes, ending the call. Thank you for your time"_
🤬🤬🤬
@@ferrumignis No joke had that happen to me with multiple companies. Automated service is just a way to avoid accountability, a sure sign of a company that has failed or knows it is too big to fail. shouldn't be legal let alone socially acceptable behavior.
I just talk nonsense until it says 'sorry I don't know what you said, we're putting you through to someone now'
"This call may be monitored to assure quality service."
SOMEBODY'S NOT DOING THEIR JOB.
This is a much better device with much more good will engineering done, compared to what we usually get from cheap CE. I am surprised. Respect!
Indeed. No IR remote control to replace batteries in or worse lose, no damned SOS, no built in battery to overcharge and burst into flame, just pure functionality.
I marvel that it got to market without all of the usual encumbrances. Here’s hoping the manufacturer keeps on this path instead of joining the usual suspects in adding things nobody needs.
@@markfergerson2145 Someone in China goofed up and let a well thought out and well designed product slip out. I am impressed at how many things this cheap little lamp does right, even saving the previous operational state between power-ups … with the exception that if it were previously all the way off, it comes back on at the dimmest setting - now that’s clever snd well done.
I fitted one of these to my Tesla in place of the accelerator pedal. I can now use the undocumented command "Max Power Now" to get to the pub before closing time.
So freaking impressive. It's instant.
They should've put a magnifying glass where the hole is. Nice portable magnifier for SMD work.
I used it as a ring light with a phone magnifier recently.
Voice controlled light might be fun if used in making videos, the commands would fit in just fine. Plus the hollow build makes it possible to use it as a ring light for cameras.
Neat, I've seen a different iteration of whats probably the same chip at my local dollarstore in Canada. It looks like a little white USB flashdrive and claims to be a voice controlled light. Although IIRC, on the packaging it claims one of the voice commands you can issue it is "set a timer", I wonder if yours has that functionality as well.
Dollar Tree in the Boston, MA, area sells a 4-LED voice-activated dome lamp with very similar electronic innards for $1.25. It operates using similar commands, e.g., "dome lamp, turn on the light," and so on.
Very cool and thanks Big Clive. I had to pause the video for a moment and found that all the usual suspects seem to carry these for various prices. Amaz on and Ali and Temu and eBay. 10 mAh standby current seems pretty reasonable.
I like this, no remote or internet needed :D
I just sent my mum off (who lives in Port-e-Vullen) to get a couple to post to me in Brighton. Thanks for the heads up!
Thanks to one of the viewers who identified the chip I found the datasheet. It's ridiculous how cheap and yet so powerful a chip like this can be. It's a 160MHz processor with 32 bit DSP(!!!), ADC, DAC, mp3 and flac codecs, noise suppression, and so on. 😮
Do you remember when Radio Shack came out with their first speech recognition chip. Must have been the late 1970s. It was same time that different toys came out that you could command with your voice, but you had to say the commands very clearly for the chip to recognize and respond. I wonder if this device uses a more advanced phase comparator.
finally a voice recognition thing that works
A light just showed up using the same chip setup here at Dollar Tree stores in the US but only with four leds, works well.
For that money, that's a pretty cool piece of kit. Just goes to show that you don't need google or Alexa or Siri or Bixby, or even an internet connection and then say "alexa" or some other keyphrase to just have things work. Put this kit into a normal lightbulb and take my money. Also looks a really good candidate to hack to a relay and do "other stuff".
Amazing find, I snagged a few of these from a local dollar store a few months back.
It possibly uses an open source machine learning model pre-trained especially for voice controlled lamps. Small TensorFlow Lite models can run on low power microcontrollers. Machine learning in cheap electronic products! What a time to be alive!
Truly amazing!
WOW VERY COOL. I remember being in college in the 80s and talking about voice recognition. Now it exists for a dollar.
Might be an example of edge computing. I haven't investigated the tools for this but the claim seems to be that you do training with the expected powerful computer but then condense the result into something that can run on a microcontroller.
Very impressive that it not only doesn't need personal training but can even cope with a scottish accent ! Clive's got a pretty clear voice, though. I wonder if it would handle glaswegian or geordie.
Assumption option based on what?
@@phonotical Based on th is sort of application being what it's marketed at
It's not using true speech recognition it's using carefully chosen commands and working of the length of sounds and number of gaps between them.
Wait, 10mA at 5V standby. listening for a wakeword? That is actually really impressive, especially for a cost-optimised product.
Now this is a nice item and with good functionality. 👍
It's amazing that they are using a JieLi chip for voice recognition! Especially considering that they seem to be running from internal oscillator (I don't see the Bluetooth crystal)? And still have enough CPU time to do it? Incredible!
The chip seems to be an AC6969D, you can find the datasheet, and even an example (in Chinese) where they made a controllable lamp with it.
I would link it, but... youtube.
Clap on, clap off, the clapper. What's old is new again. Great video, Thanks for sharing. I guess it's someone's bright idea". 🤔👍
I have a similar , but smaller one , from dollarama , in canada, the comads are written in the back, they are the following, and I imagine they are the same as yours :
turn on, turn off, light on, light off, go to bed, red colour, white colour, blue colour, green colour, green colour, pink colour, purple colour, yellow colour, change colour, brighten the light, dim the light, maximum brightnes, minimum brightness, set 1 hour times, set 2 hour timer, cancel timer
Different prompts.
How a tiny low wattage processor is able to recognise words and act accordingly is beyond me
That's because it's smarter than you are! 🤣

@@mfx1 Or is it? 🤖🤖🤖🤖🤖
Always enjoy your shows. Saw this one and of course I had to have one. amazon didn't disappoint @ $6.00. 😊
Brighten the light HAL
I believe the algorithm looks for a pattern in the sound envelope and is less sensitive to the frequency or speed of the words. Fancy sampler keyboards with your commands stored in the samples and played back at different rates/keys, would verify that.(Or a fancy sampling sig gen) I can't find the lamp here to experiment with.
Regardless of how many people want to dis assemble and figure it out, I'd just keep handy and use for every day task. It's pretty darn cool for what it is. Nice one Clive!
Amazing how well it works for the price. Just think of the price of that thing if it was an iMac accessory....
That would work very nicely for when I'm sleeping in the back of the van when spannering for race teams. I'm always fumbling around for the switch for the leds that I've got wired up.
I remember the voice commands on 90's Ericsson phones. You had to record them and they still were shayt.
People were doing this kind of thing with X10 modules and sub-100MHz processors back in the mid-late 1990s. It was no Alexa/Hue, but it worked well enough to control lights and fans and stuff. My point is that you can make this work with surprisingly little tech. An RP2040 should be able to handle this with no trouble at all.
This thing has a lot less (and in some ways a lot more) functionality than an RP2040. The JL chip started life as a Bluetooth speaker processor and even in small quantities sells for under 50 cents each. The JL chip can run at 160 MHz, has a 16 bit ADC and two 16 bit DACs with >90 dB S/N. There’s also USB, Bluetooth, LDO, charge controller, DSP snd some other stuff. It is possible a lot of functionality was masked out on the chips made specifically for these USB lights.
@@wtmayhew Charge controller even?? o.O
That is crazy...
I am somewhat familiar with JieLi, but didn't know they had chips that were THIS integrated..
@@Versette If I read the data sheet correctly… (not guaranteed) It looks like very few passive components are required to turn this chip or some variant of it into a Bluetooth speaker. Like a few resistors, a few capacitors, line driver and speakers, microphone, battery and that’s it. Amazing!
@@wtmayhew I've got a bluetooth speaker with a JieLi chip powering it, and it's got multi-chip addressable RGB LED rings around both of the speakers, and on-device voice controls if you're connected to a dumb bluetooth device (like my Walkman). seems kinda crazy how much functionality *isn't* being used here.
@@wtmayhew - the JL chip pins functions are selectable at programming/run time through their SDK. I don't think they make specific USB light chips, they just offer the same core/power/io capabilities in different pin size packages and let the customer select what functions the wish to use. A number of the pins not used in this light are those dedicated to the bluetooth RF and left unconnected on the pcb.
I think they may charge different annual licences levels for their SDK though depending what core functionallities are enabled or not. In effect a soft masking of the SDK to make money.
That's extraordinary functionality for such a small cheap IC.
Amazes me still how they can produce something like this, ship it halfway around the world, they make a profit, retailer makes a profit and Big Clive has something to play with.
Your voice command enunciation reminds me of that voice controlled lift sketch from Burnistoun
Eleven. Racist elevator
"Who taught you that accent, Dick Van Dyke?”
Now that is impressive, I was expecting tat!
That old voice control thing you mentioned - X10 Powerhouse? LGR did a video on that and it was lorra lorra interesting.
There are two different LEDs used in this device, which achieve 3 different color outputs by lighting the LEDs individually and in combination. You could use this device as a relatively simple voice-operated remote control by opto-coupling light sensors to the LEDs to control a circuit relay to turn another circuit on and off.
Or just put relays across the LED lines.
@@TomCee53 LEDs will have PWM to get the dimming. Relay might not be too happy with that.
@@j.f.christ8421 Bung a capacitor on the gate of the driver FET. It's usefully already got a series resistor to form a low-pass filter. Of course, below a certain brightness it might not come on, so chuck in a series diode (and the pull-down resistor will ensure it switches off).
That seems like it has some beautiful hacking potential. Warm, cold, or both, at 5 different brightnesses, plus off makes 16 total states, controllable by voice command in a single chip. That would be an awesome addition to loads of projects with nothing more than an attiny and a couple more passives to interperate the chips output states into other ones of your whim. Would be 1000 times more awesome to have the raw chips and a way to program custom commands. I bet there's a decently robust little microcontroller inside that you could get to use the two output pins in even fancier ways.
You'd be surprised to find out that the little chip has BT 5.1, an integrated DAC, USB, SDIO, and FM radio. It's a repurposed Bluetooth audio chip.
If this was about 100x brighter, I'd replace all the solar lights in my house with it. It's so much easier.
back in the 80s I was one of the pioneers of computer voice and we did some voice recognition. It wasn't very good, I'd say "elephant" and it would type "6"
Very unique
Clive: What your eyes the lights about to…(flick)
Me at 2am: “ahhhhh”
Clive: “…on”
Nice, hack it and feed it to dimmable LED driver and you got cheap voice activated domestic lighting with no reliance on the cloud, gonna grab myself some for experimentation.
I still have an old voice recognition IC in original packaging from Tandy (remember them?) they used some clever tricks based around how long the command was and gaps between words, there was little actual "recognition" in this case for example "Turn on the light" and "Turn off the light are virtually the same and quite long with three gaps but it's a toggle function do it doesn't have to know the difference between on and off it treats them both the same. Change colour is short with only one gap, dim the light has two gaps and dim is short, brighten the light has two gaps and brighten is long. It's basically a lot easier if the commands are limited and carefully crafted.
That may explain why they choose "dim" vs "brighten" for the light intensity.
@@trueriver1950 It's exactly why.
JL (JieLi) is best known for "The Bluetooth device is ready to pair" and "The Bluetooth device is connected, uh, successfully." The SoC in this light is the same as what they use for BT speakers, but just running a different firmware.
WOW quite a little chip! only thing I would have done different in its design, would be that after you give it a key command, say "dim the light", you could just say "More" or" less" to go to the next level. or "Change Color" and then "next/Prev." if the contents of this chip could be extracted, it would be very interesting to see what it contains !! 💥❤💥
Nice circuit, surprisingly works well
There are a few options for 16 pin voice control chips but they are probably different numbers for the same chip. They are audio playback chips with voice control options. YX6100-16S
Or JieLi equivalents
have you shouted SOS at it? 🤣 Nowadays Im not that impressed, but at £5 its not bad.
I assume it's PWM-ing the LEDs for the dimmer function? It would be really useful for a reading light if your less mobile, or a hall light for that midnight pee. interesting thing 2x👍
I could definitely use this for airbnb for the kids. The rooms usually don’t even have warm light for sleeping
A lot of these voice controlled toys actually use the beat pattern of what you say instead of recognising words. Probably just high pass filtering + comparator + timer onboard. I believe there are chips that do this dating back into the 80s. An interesting thing to try would be to say something ridiculous at it that has the same beat to one of the commands.
I think the chip is a Jie Li chip. It is a Chinese manufacturer specialized in MP3 and Bluetooth chips. I think the chip in question may very well be a MP3 player chip, because it has an analog to digital converter and a powerful digital signal processor in a convenient SO16 package.
Reminds me of the 90s "home automation" system with voice commands. It works only if you clearly say exactly what it expects. Also the Sonos Roam his this local voice command and its so fast its wonderful.
That's an amazing little thing!
Now, this is smart tech I can get behind!
That JL chip is produced by JL Audio.
It's usually used for (cheap) TWS headphones and Bluetooth speakers.
I don't know if someone mentioned it already 😅
2:20 Vsauce2 recently did a nice video of the "Butler in a Box" from the 80s on the channel "Popular Science". This is interesting when compared to something way more modern like this
When you wake up with a small patch of hair missing and an urge to behave as instructed.
I used one of these for a while. Then, one night, while I was lying in bed, it turned itself on without me saying anything.
The light turned red for some reason and started calling me Dave.
I was uncomfortable using it after that.
Did it say "I'm sorry, Dave, I can't do that"?
As others have said. It does not surprise me that we find our friend JieLi ac69xx chip inside of it. I might need to get one and try to put it into dfu mode and duml the software. I wonder if it has an sos mode though.
Do you remember the bluetooth music lamp? That also had a JieLi chip inside. Pretty powerfull with a 32bit risc cpu and a lot of perhiperals.
FYI, If you look into the shop named after fierce women from greek mythology you'll find those unofficial voice commands as well.
It’s a ‘ring light’ - how lovely!!!
Wait until you hear about 'ring doorbells'...
Amazing bit of kit. Almost asking for further applications of a non-light nature!
JL is made by the company Zhuhai Jieli Technology. Apparently you can decode the letters and numbers on the chip. Looks like this chip is made in 2022 indicated by the 22 after AB. The very last number shows how many Mbit flash it has, so in this case it is 4 Mbit flash. The datasheet number should be AC6969D and it seems to match the pinout. I have no clue what kind of firmware would be loaded in it for voice recognition, truly amazing
if i had scrolled one bit further i would have not ended up in a google hole and placed a redundant comment. amazing detail on the flash capacity i completely missed that.
