- This is a huge step in E-Paper technology! These screens have all the benefits of electronic paper, including excellent battery life, image retention when un-powered and great visibility in sunlight, but they are finally multi-coloured. Also I make an auto-changing E-Ink Picture Frame 😊

Electronic Ink is a familiar technology to everyday makers. They are low power displays that have great visibility in sunlight and preserve the displayed image even when not powered. Once you display an image to the screen it will stay there for ages, up to weeks, completely without electricity. Commonly applications have been signage, E-readers or simple project dashboards. The technology refreshes slowly so it’s never been for fast updating user interfaces. Up until recently the technology has been limited to monochrome with a single colour. But no longer! Welcoming in the Inky Impression 5.7" 7 Colour, 600x448 Pixel E-ink/E-paper HAT capable of running with a Raspberry Pi Single Board computer. Thats right! Seven colours! They are Blue, Green, Red, White, Yellow, Orange, and Black. Combine these block colours with dithering, a method used by computers to approximate unavailable colours from a mixture of other colours, this Electronic Ink display can produce to the human eye all the colours! HAT means simply Hardware Attached on Top.
This technology's full name is ACeP Micro Encapsulated Electrophoretic Displays. Inside every one of these screens are thousands of tiny oil bubbles with colourful charged particles. Depending on the current flowing above or below these oil filled bubbles certain particles are drawn up or down. When the particles are drawn to the top of their oil filled bubble we can then see their colour displayed on the E-Ink screen. Its so cool! It's ink, but way better. Huge shout out to Pimoroni! From hardware assembly to image display tinkering this has everything you need to hit the ground sprinting with these displays.

Nice video - and the fact that you look like Gretha Thunberg makes it environmentally friendly. Good job!
Cheers mate, I'll have to keep growing my hair to get the full effect 😊
@@Core-Electronics Sorry for the comment. I forgot to take my medication that day :(
Take care mate
omg så sant 😂
@@prodsani Lol
It is SOO amazing that they make them with 7 FREAKING COLORS!!! How in the world does that work??? =.=!
I dive into how they function a little bit more in the Article write up if your curious 😊
Appreciate this breakdown, super helpful for getting up and running!
Cheers mate 😊
This was really helpful, thanks!
amazing video, thank you
this is dope! just the project I wanted to do with my raspberry pi - the possibilities are endless!
Glad you dig it 😊!
"How dare you!" 😂
Really cool -- subbed
Cool
single raspberryi pi , multiple e-ink displays for a photo collage frame would be cool...!!
I love that idea!
Hey this is cool - appreciate the effort.
Do you have any plans for a video where you share how can one build a setup with Raspberry Pi and E-ink display to do basic tasks like browsing the web to read and do basic writing? I've been looking for options but they are all pretty expensive.
would you want to wait for each new page load or scroll?
Good
Thanks for making this video. It's too bad these screens can't do real-time image refresh.
My pleasure mate and my fingers are crossed for Effective Partial Refreshing with these displays. That would open up these screens to a lot of potential uses.
Dude, you're amazing! I'm going to buy it now!
😊😊😊 Much too kind!
Do you know of any larger electronic ink displays? I want to replace some physical 16x24 art prints I have, and want to make a large black & white e-ink display to use as an always-on calendar also
Great video, amazing explanation! 10/10. However, I want to use my raspberry pi as a host for my website and (the display) for notifications regarding my instagram followers and other stuff. Is this possible? (Raspberry Pi 4 Model B 2gb) - Also can I code with Java? - And can you give a tutorial on how to display self made notifications ?
Thank you mate! You can definitely code with Java and Raspberry Pi, one of my predecessors recommended Grasshopper to learn how - grasshopper.app/curriculum/fundamentals-1/ . This fellow created a Raspberry Pi Social Media Notifier which you can learn a lot from too for your project - www.instructables.com/Raspberry-Pi-Desk-Notifier/ . Hope this has helped and definitely come pop a message at our forums if you need anything else 😊
What's your thinking about the Inky Frame? Would be great to have more tutorials on that, since it's more approachable (everything is in one package).
i need a bigger display, any idea where I can order it
This is great! Is it possible to use the E-Ink display as a monitor? To specify, can you use the E-Ink display as a normal computer monitor to use programs/browse the web?
Only if you're very patient 😂. The 30+ second refresh rate would not be very suitable for standard monitoring tasks.
Do you know of any e ink hats which would be compatible with the raspberry pi? Monochrome would be perfect, I'd like to build a sort of cyber deck to do things like make spreadsheets and read books, nothing needs to refresh quickly
Hello! I was thinking about getting myself one of these displays to frame my digital art but I wanted to make sure how they would look on the display.
I make each piece with 6 colors that are pretty dang close to the ones used on the display and I wanted to see how they would look.
If you’re still interested in letting viewers see how specific images look on the display like you said in 10:11 I’d be willing to get in contact with you on a platform where I can send modified images that’re modified to fit the display.
Hit me up on the forum mate, I'll see if I cant sneak in some images 😊 - forum.core-electronics.com.au/
Rest assured though if your using block colours the result is gonna be rich and stupendous when it gets displayed on this 7 colour display!
@@Core-Electronics Will do! Now it's time for me to remember how forums work. 😅
@@Core-Electronics I have sent images in the thread relating to this video. I hope it's fine for me to send them in there 😅
Is there also a way to control Multiple eInk Displays with one pi?
I tried to do this on the new inky 7.3" that I just got and the install script doesn't seem to work? when it gets to installing inky pHAT & wHAT library for Python3 it says:
error: externally-managed-environment
my e ink display shows the picture not portrait format, its streched and awful in landscape can i change this anywhere?
Can this be used to make a e-ink comic reader?
Yes
would the pimoroni software work with a waveshare display? thank you?
I reckon you will need to alter some scripts to get that to function correctly. Both are totally open-source so it should be of some comfort to be able to see how both system and their scripts are functioning, you wont be in the dark and able to base one of the other.
@@Core-Electronics ended up returning and going with the inky display, Thank you for your help. Everything works great!
I have a question.. you made a photoframe out of it.. can a photoframe be made in such a way with better screens like lcd with high resolution. if yes can you make a video or just explain me how to do it
Yes, you can connect any display that supports HDMI.
I just got mine set up today and the image is really dark no matter what I try. Has anyone else experience this and been able to solve it?
I wonder if they will ever be able to speed up the refresh rate. 35 seconds is quite long.
Do you play Spanish guitar or was a woman assembling the components?
Do you want a presentation tip? Keep your head up and your eyes forward. The head down eyes up.. just a little creepy.
I guess deep down I have a little bit of YMS in me
omg a man's female nails are not normal
Maybe don't stigmatize other people's appearance and work on your own, no doubt many and quite severe, flaws instead.
Maybe dont atigmatize othet People comment's usefullness and worka on Your own ;)
