128 megabytes of ram not gigabytes lol, Great video Matt

[@notenoughtech]

Haha did I? Darn ... Maybe I'll get it right next time🤪

[@Bradford1040]

@@notenoughtech no biggie, hope you are doing OK, I have been taking a tasker break, and still plan on getting an ender at some point. Money has been tight. But best wishes always, to you and yours.

[@notenoughtech]

Thank you keep safe. I have seen a couple of deals for ender 3 on banggood. One of my followers got one for like £130 (not v2) which is a really good deal. Summer sale is on so do monitor these as it may pop in your price range. Fingers crossed

[@HumbleHustle101]

Very nice video. One of my sibling is blind and I am wondering if I can make a project where I can train this device on objects to be recognised and the device can pronounce the name of the recognised object, or tell about next person's emotion via face, or perhaps do OCR. Does this device has audio output? How long does the battery last?

[@notenoughtech]

Hi, usually M5Stack devices come with a battery, but this one doesn't have one so it depends on the battery you'd attach to it. The basic object recognition would be able to do some classification for you, but you also need to work with distances. Object recognised far away would be little of use if there are others in vicinity. It's a very humble project and I hope you will find a way to resolve it

[@HumbleHustle101]

@@notenoughtech Thanks I appreciate your appreciation. It seems there are 2 models of this device one is without wifi and the other one is with wifi. I plan to purchase the wifi one. But what I am specifically interested in is with the current hardware how many objects can I get to train it on? and secondly can I perform OCR are there any such libraries that I can use?

[@notenoughtech]

There is not enough resolution and speed for OCR (other than the big signs like for cars). You don't want to have too many objects at once but focus on narrow field of view. Otherwise you get constantly spammed with text and messages. Record a walk with your sibling while you describe the things around him and get feedback at which are important to him. This will give you a rate and number of objects. You could easily get a couple at the same time... But I'd aim to do 2-3 at best while centered. This way head movement gives you approx heading for object.

[@HumbleHustle101]

@@notenoughtech thanks, Ok I will order it and start to explore it but please do make a video if you find some more powerful computervision ready to use programmable camera if you come across any. I have subscribed to your channel.

[@markb2769]

I could use this. I'm converting a 3 metre high ambulance into a campervan. I'd love to have a system that would look out for height restriction road signs and warn me (because it is easy to forget). If it could parse the text off the sign and check if my van will fit that'd be all the better.

[@notenoughtech]

And add it as a HUD projected onto your windscreen :) BTW that sounds like a fun conversion - hope you keep the first aid kit :)

[@BrandonJacobson]

How can I capture the serial JSON information with Python? I tried connecting to it using pyserial like if it was an Arduino, but it doesn't work. I don't know what port or baud rate it is. I can connect to the camera through Putty, but I'm not familiar with ssh to know what to do with from there.

[@notenoughtech]

The usb cable works like any network card. Look up the IP address and you can get the JSON data via REST or serial

[@BrandonJacobson]

@@notenoughtech Thanks for the response! I used the Python requests module and was able to access the v2 camera. I don't know how to access the Object Detection JSON data though.

[@notenoughtech]

@@BrandonJacobson By default camera is set to stream so you have to send the payload to set it in the correct mode, then it should start sending the output. docs.m5stack.com/en/quick_start/unitv2/base_functions You will find sample for serial at the bottom of the page as well

How do you get the data off of the device? I want to feed the data to my own ESP32 app that I have developed?

[@freddiebeltran8174]

Bogus there's stuff out there that you wouldn't find on the dark web.

[@reneeformoso2267]

Really helpful vid !! Do you know what units the Motion Tracking values are set to? I've tried using the M5stack UnitV2 for Face Mask Detection and Motion Tracking but I'm quiet unsure with the unit of measurement the x,y,w and h values are set to.

[@notenoughtech]

They should be on screen coordinates of the corner and size of the square. I'm speaking from memory so worth looking up the docs to be sure I'm not talking out of my butt

[@genkishan]

Amazing video ty! Will it work on Win 11?

[@notenoughtech]

I see no reasons for it not to

[@andypeoples]

HI, When will the follow up video be released? This looks to have so many possibilities. Great Video!

[@notenoughtech]

I can't promise exact date, but I have not abandoned UnitV2 just yet- a bit more info about WiFI: notenoughtech.com/home-automation/m5stack-unitv2-update-brings-wifi/

[@oscarrv50]

Hi, Mat thank you for your work is very interesting. Please where you have found the car holder for M5?

[@notenoughtech]

Oh I had a spare suction cup with 1.4 inch thread from insta360 camera

[@josegodinho7342]

Great video, How could integrate this camera with node red?, MQTT? REST?

[@notenoughtech]

At the moment the JSON is streamed via Serial over the network. This can be intercepted directly through USB/Network. With WiFi, I believe we should have REST

[@alzalame]

Nice and super useful, i followed your instructions and achived very good results , please continue your videos about this amazing device and how to utilze it in automation , thank you very much 👍👍👍

[@notenoughtech]

Thank you, I will

[@laurencevanhelsuwe3052]

How likely could I create a system which logs the take-offs of planes with this? The goal would be to log aircraft registration (their "number plates") and take-off time. If this could be possible by just training it with lots of pictures of planes taking off, that would be very interesting.

[@notenoughtech]

You need better optics. You could train it in perhaps brand recognition based on patterns but with this resolution and optics you have no chance of ID planes in flight

[@laurencevanhelsuwe3052]

@@notenoughtech Shame. So close, yet so far from a solution.

[@MrMechaMatt]

Great video Mat, you're always contributing to my projects! I need facial recognition on my doorbell (thinking Dahua) and magic mirror.

[@notenoughtech]

Ha! Magic mirror is on my mind to at some point

[@DIYtechie]

Thanks 👍🏻 Looking forward to seeing if it can recognize faces reliably.

[@notenoughtech]

We shall see soon

[@Mephmt]

That's amazing! It's great to see this stuff coming down in price and becoming more available to everyone! I look forward to the next video! I'm thinking about use cases for this. One that I think would be really handy would be to train a model on mine and my wife's car, stick the device in front of our garage, and then when it sees us pull up, it'll automatically open our garage for us.

[@notenoughtech]

You could easily do that, plus train up faces.

[@jasonl6486]

Hi, can the device run without external power from USB?

[@notenoughtech]

It doesn't have a battery built in so you need to deliver the power to it.

[@andrewtitcombe8378]

Can the AI be trained to read number plates?

[@notenoughtech]

You can but you have to account for the resolution of the camera. For APR done at the distance you'll need better optics/res

[@alidollar1994]

Looks super useful, thanks for sharing it with us. Will be looking forward for more videos on this tiny but useful device
