Thanks for the video. Keep us informed, because the idea of using this screen in home automation is a good one. This screen could be in each room as a remote control where you can view and change climate settings, light, etc. It can be useful for your DIY smart heating system as a remote control in the room.
I'm split between having it as a docked panel or personal device with screens to switch. The only downside is that "boot" from sleep mode takes a 3-4 seconds, but it could be triggered by being undocked from the wall
@@notenoughtech I think it could be docked to the wall, but it can also be picked up if more use is needed. But the normal state would be on the wall and maybe also on the base with power connection.
If connected to power in docked state, e-ink becomes redundant and useless in evening situations where the light isnt on. I would like to make a small pocket Social Media checker that displays recent notifications when connected.
I think using this as a smart home touch controller would be a good idea.
Yes I want to get the hands on that small panel in demo and make it work
Very interested in using this or something similar as a HA dashboard The slower refresh rate doesn't matter for that sort of use.
Also, it looks good as a dashboard. It's different to having an ipad stuck to the wall
Its really cool device have to say that M5Stack guys always create a nice products.
from where can I get this please tell me
Looks like it would make a great universal remote control, especially with the expansion ports.
It could have so many uses ;) I want to try to make that mock up automation panel real
this would be sick! (if it was in stock)
Check AliExpress link they also have it there
Wow!
What an introduction
😊😊😊
keep it up...great video
Very good video, thanks for sharing that!
My pleasure just to let you know I got the confirmation that m5paper will get uiflow support
Great video, I have once and I want to put it on my frige, as a shoplist reminder. But the magnet is weak ... I want to open it and replace. But I have a lot of fun with it.
Get magnetic stripes for fridge. It should work well too
Nice
"Out Of Stock"
Of course... ¬.¬
Have you tried the AliExpress and banggood links in the article? They do have stock from time to time too without scalping the price
It already sold out!
have you tried links for AliExpress and Banggood? Some units were there as well
Hello, what about battery life? Did you measure the average discharge time after a full recharge?
Thank!
Hi, I haven't measure due to the fact that it will depend on the sleep policies. E-INK uses next to nothing in refreshed state. I charged the device once since arrival (after xmas) and I still have 40% of the battery left as in the dormant state it doesnt take much power (only RTC is alive)
@@notenoughtech Thanks a lot! The reason I was asking is that I bought this device and after I switched it on, the battery drained very quickly. Basically after 2 hours it was off. I just used the out of the box software. Did you change something from the sw perspective?
Thanks
@@verluc ESP32 draws about 150mA -250mA depending on usage signal strength etc. The battery is 1050mAh which gives you about 4h in ideal circumstances. That's without taking in consideration the touchscreen, sensors and the display. I'd expect 2-3 h out of the device in constant use
@@notenoughtech Ah, ok, it does make sense. So to make it last longer the sw must be tweaked appropriately. Thanks for the feedback!
I am now testing it. It is running wifi (requesting NTP time and write to SD Once a minute) from 7:00 to 12:00 ... 5 hours. But the e-ink is good for a sleeping devide. I have test wifi, request a NTP time, write battery level to SD once per minute, and sleep (M5.shutdown(60) ) I was running this way almost 2 days. Now I am testing it running it once every 10 minutes, I can tell you when it finish.
Could you create a sketching type application on it? Is the touch system of a high enough resolution to allow drawing? Is the screen refresh rate fast enough?
I don't think you would be happy with the result. It would be possible to draw on it, the touch screen part is responsive but the refresh rate would lag behind
@@notenoughtech That's what I thought. Does the touch system have pixel-ish level resolution? Or does it only have a few touch areas?
If you check the video when I was showcasing the touch, you can see the values changing for the touch coordination, the touchscreen is pretty accurate. Touches register well just screen takes moment to refresh and show actions.
@@notenoughtech Ah! Yes, I see that now you've pointed it out. Thanks a lot, that answers my question.
No problem I'm happy to help. If this helps... It's a pretty cool device as is
i want to make my own custom e-paper display reader for pdf files and other e formats, but want larger screen size
A read a out upcycling kindle screens. They are relatively easy to work with and well documented
Would it be possible to use some thing like this like a map device?
Yes but bear in mind, it has no GPS built in, but you could get GPS via GROVE extension if you are interested in position tracking. But traditional maps could be loaded and displayed in a standby mode
Hey! is there a chance to connect to an Bluetooth Keyboard and use it for Text as a freewrite Alternative? just writing?! can you please help? Thanks a lot and viva Polska!
Nie próbowałem ale teoretycznie można by bylo to zrobić. Wymagało by to odpowiednich sterownikow aby ESP w środku wiedział co z tym zrobić. Nie będzie to banalny projekt. Zwłaszcza że zazwyczaj robi się to odwrotnie i to urządzenie z ESP wysyła sygnały klawiatury do komputera
love this but is there any way to connecting ethernet for areas where this is not wifi??
Not directly, you could look at M5Stack store for ethernet adapter boards .
How about battery life
This depends on how you set up the device. Esp32 can draw up to 250mA at high modes plus whatever other hardware is operational. With sleep policies this can last year's
@@notenoughtech thank you
but can you play games on it?
That depends on game. You could play stuff like chess
Hi, Any chance for disassembly of that device ?
Check out the linked article for pictures
I wish I'd seen this before I bought one ....but you didn't do it soon enough. I assumed it was supported by UIflow DOH!
Support is coming up just got the confirmation today.
@@notenoughtech Great, thanks for the info.
what part of eastern europe are you from?
I'm polish
Why isn’t Amazon smart enough to take this hardware and make a nice pocket Kindle?
My guess is that focus groups tell them that other devices are more likely to sell
Can we read PDF files on it?
Not by default. You could see if there is a esp32 based reader
Thanks for sharing Mat. (You don't have time to read, do you?) 😉
Lately just manuals of things to operate
I read all the classics already though ;)
guessing it's not possible to access your kindle library on this
Depends how hard you hack ;)
I Hate Paper .
Such a strong word. Paper is nice :)
