Tearing down some more cheap and nasty smartwatches

- In whch yr hmbl svt gets some more sub-$10 smartwatches ($4 and $6.50 respectively) and takes them apart to see what makes them tick. Figuratively.
Turns out these things are based around some pretty decent hardware, much more so than the last LT716. Also, all three watches (these two and the LT716) use different CPUs! The expensive watch -- which was $6.50 when I bought it but is now $5 -- is actually pretty nice and might, with some work, be usable as a watch.

15:24 looks like Bluetooth profiles.
One to be for audio only (like to be used the watch as a earpiece?)
One probably connect to "smart features" aka notifications
And one for remote controls?
I don't know, but definitely bluetooth profiles.
Yes! It is! I tried pairing it with my phone (without using FitPro), and it showed up as a headset device. Called "watch" (sic). Of the three audio profiles in the menu, "Portable ..." and "intellige..." (sic) seem to be identical. I successfully played audio through it, although the quality was so bad that it was completely unintelligible. I did not try the microphone but I bet it's hilarious. It _completely_ failed to occur to me that this might work without having to use FitPro. Thank you very much!

These cheap smart watches remind me of the cheap g-shock watches from the 80s that pretended to be expensive dive watches. Except they weren't waterproof and only had a basic watch inside it.
An amazing amount of hardware (and software) for just $4! So many possibilities, and very little to complain about. Thank you for digging into these and talking us through the hardware.
This channel is gonna blow up soon! And I am all in for that :P
I, too, expect it to quickly disintegrate in a messy fireball.
@@hjalfi Now you have to upload another 10 hours of writing yet another assembler to prevent your channel from exploding
@@Lemon_Inspector I do actually have 45 hours of programming in reserve (and counting) in case I need to drive people away...
@@hjalfi I like it when things release magic smoke. Hopefully you'll learn a magic spell to cast fireball with the electronic devices.
I ended up buying two of the previous one you showed (using the affiliate link), and I'm waiting for them to arrive and start playing with them!
I _really_ hope I managed to link to the right watch there. I suppose I'll find out in a month!
@@hjalfi I'll let you know!
Please do more videos like this❤❤
Love the intro "These are the expensive ones, these come in BOXES" 😂
prolly one of the best channels i found this year
I would love to see a continuation on the rev eng about the fnirsi scope. I try to paste the link here, but my coments disapears...
Yes, the UA-cam automoderator just disappears anything with a link in it. I do actually have a followup planned, but projects seem to arrive more rapidly than I can do them.
15:45 that menu style is actually pretty neat. Rather unusable un that small display, and a little slow, but at least it looks quite impressive (note that I don't have a smart watch so I have no idea what exactly they were copying there)
The style is directly ripped off from the Apple watches. I do have to give them credit for making that style of thing work at all on a device with so little RAM, while at the same point wishing they hadn't tried.
I like the way you show the 3d projects. I hope you will do more of them in the future.
Have you thought about poking around with the pine time watch from pine64? It's already pretty open source but it could a fun thing to mess with
10:38 looks like the case has a part for vibration motor but... who needs things in right places
I hadn't spotted that, but yeah --- that enclosure on the left is clearly intended to hold something which rotates. There's space for a much bigger battery, too. I'm pretty sure that this has been bodged together from various parts which were available cheap.
I assumed it just came out from its position during disassembly, but that would require a 135° rotation...
That first one has the mold quality of 1969 army men.
You have tot this with the hello watches 😮 nice work😊
Hey can we install any light weight OS in DVR to playback videos imgs audio like a DVR HKVISION btw love your content keep it up
Recently got a Tracer branded smartwatch. Seems to be running a similar system to the last smartwatch you showed
Hope you can look into the DZ-09 eventually, it has a removable battery, SIM card slot and SD card slot in a smartwatch!
Something something "fernly".
Wow thanks for the video
Hey! Thanks for the video it's really great. I want to create a DIY Smart Glasses (like Rayban Stories). I'm a computer scientist but these things are beyond my knowledge (I create amazing software tho :P) Can you recommend any resources so I can read/watch on my free time to start building the smart glasses?
Nice Work 😁
It’s scary to think that some people will definitely buy these watches and check their vitals using fake sensors!
I have no mercy for people who fake medical equipment.
Keep doing things like these.
Just subscribed. Hope to see more reverse engineering and troubleshooting from you.
you can fix the fpc by scratching off a bit of this plasticky material that has the copper traces sandwiched between and extend the solder lines beyond the crack this way :3
Sadly the screen is in a better place now, by which I mean my ewaste bin and in pieces.
I'm looking forward to installing a good, usable, working os on these watches.. if you are doing that.. I'll subscribe!
Please try hello Watch 3+
Do the square one it's awesome
subscribed so i can see what you do with these in future.
I'd like to see what is inside my Xiaomi mi band 6 and how hackable it is.
i am interested in programming but have never worked with hardware level stuff like firmwares, OS etc where should I start learning and implementing stuff
i consider myself good at c++ for competitive programming though
Get a Raspberry Pi Pico with one of the games hardware addons (VGA out or an LCD, gamepad controls). It's a really good chip with an excellent C++ SDK. You can then write old-school games for it. It'll teach you about bare-metal programming without the pain of working on the really constrained devices in a reasonably fun way. Plus there are lots of libraries for it and an active community.
@@hjalfi thank you sir will get on it
you could just search "Mbed OS" and buy some compatible hardware
next buy and take apart one of those cheap apple ultra watches to run micropython
I love your stuff but you need to fix the focus on the camera when you handle objects, try to raise the depth of field or better control the focus, perhpas focusing it on your hand and then locking it, cause here your table is perfectly sharp but your hands and watch are so blurry
lol @ the horse watch face
This feels like reverse Shenzhen I/O
These things are basically ewaste from the start. If only they ran micro python from factory or at least came with documentation they could serve a far more useful life.
I don't get the hate for the horse watch face. It is clearly high art.
Only when the watch is on a plane.
i don't understand the ui decisions of most of this watches, menus that lead into nothing (fb and twitter), hidden stuff like to change watchfaces you have to long press it should not be assumed to be there it should be additional as a shortcut to a config menu, i wouldn't even add long press to a watch it's too easy to trigger unwillingly, icons with terrible contrast for viewing on the outside, etc
from a watch i expect the main extra features to be stopwatch and timer, then as secondary the other stuff like notifications, fitness,etc
it would be a lot better if you could just turn features on/off and those get completely hidden in the watch ui, and would be even better to be able to reorder some menus.
i would like a FOSS implementation in a watch, we could do so much better, sadly i don't think that will ever happen.
The non-functional menus are most likely not working because it's not paired with a phone, so that's semi-reasonable --- but I should at least expect an error message (and not 'Null...'). I agree, the UI is total junk. Looking at the quick menu on the better watch, one of the options is the menu style selector? But why? It's something most people would only ever set once. I got a comment elsewhere suggesting that this are repurposed pulse oximeter boards from the... er... recent kerfuffle, and if so I suspect that there's a semi-standard smartwatch stack somewhere that's been slapped onto the boards haphazardly. You're right that no concern for quality, usability or anything has been done.
There are some open source smartwatch stacks; e.g. WaspOS runs on the PineTime, which has similar specs to these. Theoretically it should be easy to port. Practically the hard bit will be getting a hardware debugger working on a development device so that they can be reflashed when a botched update bricks them.
I WAS SO DISSAPOINTED WHEN I HEARD ITS A SQUARE AND NO TOUCH SCREEN
yay more watch fucking arounf
Now take out the LT716 display and solder it to LP715 and see if it works😊
Bro Why you dont Crack the xiaomi mi band 6 it self? It's cheap and very good watch
Because for that price I could buy ten of one of these!
@hjalfi that right but it give you more features, anyway, can you help me to write custom firmware to it? I just wanna know which pins are swdio and swclk
@hjalfi this guy did it already but not shared project and pins, I wanna put custom firmware into it but I don't know which pins are swdio and swclk, and this guy didn't answer comments : ua-cam.com/video/jBDWfaLzZtM/v-deo.htmlsi=uqQRf_3VCm1yZqDs
@@Amir1300aht I'd love that too.
I wanted to watch this, it's very interesting, but I cannot stand the sound of the constant lip smacking.
Thanks, I hate this.
Whoever sells this green monstrosity should go to jail
I hate these watches with fake HR monitor !
PLEASE don't use tweezers for levering things apart. You could very easily snap off components, tear ribbon cables or worse puncture the battery !!
Use one of those cheap plastic phone repair levers....👺
