*What kind of data would you want to show on this E-ink display?*
Daily tasks? Phone notifications?
Stock price for them chicken tendies... we're going to the moon or the back of Wendy's
KNX Integration of various status and Solar Inverter power/energy, Battery state of charge. You're on to something here!
I'd love to see something like this as like, a novel take on a stream deck with buttons to control OBS and whatnot
Absolutely love e-ink stuff so it's always so fun to see what folks can make with it
Turn it into an RPN calculator. Possibly implementing some of the features of RPL, most especially the ability to make/use macros. (RPN = Reverse Polish Notation, aka Postfix notation. RPL=Reverse Polish Lisp, which is a Lisp variation using RPN instead of Polish Notation aka prefix notation. Most americans, and modern programming languages, use infix notation.)
Can you tell I miss my HP 48?
To-do list for the day.
Slick design. *AND* it’s open source? *AND* it’s well documented?!? What a KING.
Bruh did you just call this slick design lol
DROP EVERYTHING YOU ARE DOING. we got 2 videos in the same year.
OUR BOY IS ON ONE.
Don't over exaggerat...OMG!!!
The hidden gem of this video is the wall weather display. I love the idea of a simple custom visual weather e-ink display for the house.
Something you can try to get rid of the ghosting that is pretty common on all e-ink displays, add a function to your code that first loads and all white image over the whole display, followed by an all black image, and finally again an all white image. Then in your code, every time you change an image or load new data, or turn off the display, call that function to clear the scree. Should get drastically decrease, if not get rid of, of any ghosting you're seeing.
I second this. E-ink readers usually have a settings to control full page refreshes after reading, say, 5 or 10 pages. It's a little slower when it comes to that page, but periodically doing the refreshes help with the ghosting.
Yeah, that's full refreshes that should clear the ghosting. As seen in the video this display (and software) can do partial updates too. These cause the ghosting. I don't know the codebase (generated by ESPhome?) but you can minimize the ghosting in combination with partial updates by updating the region with a negative version of what it is currently displaying before showing the new content.
And that's where we come to the massive disadvantage of those epaper displays. They have to support partial updates and ideally partial updates are also used to minimize ghosting (haven't seen a "driver" that can do it automatically).
For such usecases where you want frequent updates, e.g. just showing time requiring one update per minute a full refresh (at least for me) is just unacceptable. A status display next to my computer which flickers every minute or even just every 10 minutes would be highly distracting.
I built something similar but smaller for the RPI a while ago, and that function is called "ShakeEtchASketch"
Seems a bit inefficient to be doing the whole thing. You could take a XOR of the current and next states and get what's changed, and then just do the white-black-destination bit in those areas. Would probably save power, too.
@@Roxor128 Good idea
Wow! I’m 51m0 from Printables, it's nice to see my own 3D model, even if remixed, shown in a video on CZcams.. I'm glad you based on it 😊
This could DEFINITELY be a kickstarter project that makes tons of money! If you had an interface for customizing it, I'd ABSOLUTELY buy one!
Honestly the idea of e-ink as an auxiliary screen is so good that I'm surprised that it hasn't been deployed yet by device manufacturers. Imagine something like a laptop with a secondary screen next to the trackpad for stuff like this, allowing for an easy on the eyes but customizable info screen that takes up little to no battery life from the larger machine. Or a phone with an e-ink always on display on the back, for the time and other stuff.
@@TheNugettinage even better: I'm dreaming of a eink display as a main driver for terminal programming.
Oh boy, I've been thinking that an E-Ink desktop calendar with tasks and appointments would be amazing for a while now... I'm so stoked someone had the same thought and *actually made it*!
Just as I thought I have seen a lot, your videos just blew my mind away! What an amazing job! I always wanted to become a good DIYer, but never really put in the efforts to become one. Your videos, especially the macro control, was such a great inspiration. Thank you so much and would love to see more of your work more often!
I am glad I didn't have to wait another year to see a new video!! please keep them coming!
always come up with the fabulous ideas that inspire us to upgrade desk setup again..... always happy to see your new video updated
In addition to the beauty and appeal of the device; this video is very well put together. Bravo.
your original oled tv setup influenced me so much! since then my setup has gotten infinitely better and more clean. i also followed the journey from 48 inch to 42, now 32. hoping to setup this e-ink thing as well in the future! your videos rock.
What you built is beautiful man, I liked it
He's back and showcasing next level stuff!
I thought about buying a simple clock on my desk setup, but you inspired me to think about purchase on of these lilygo clocks and program it myself 🙏
This is just beautiful. I can't stop looking at it.
The thumbnail alone was enough to give a like. Great work and beautiful presentation
Dude you’ve made something really beautiful
As cool as RGB, E-ink display actually look really nice and classy, i hope it will be use more in the future
Every time we think David has the perfect setup, he makes it perfect-er!
That's really awesome looking! Well done!
LOVE IT! Would gladly buy something like this. Also to set Busy / Available states on office desks so people know when you can be interrupted or not for instance. The same for meeting rooms information, etc.
a fellow home assistant user? instant sub, love seeing the love e-ink is getting nowadays
Nice, just what I was looking for the whole time. Really interesting!!
This is really neat! What a fun project
I wish you posted more! I love your videos!
Kickstarter is waiting for this 😍🤩
Solid work, solid product.
Your voice is so relaxing, you could be talking about anything and I'd pay attention.
Looks very nice. Well done
Boy, am I glad this isn't a commercial product because I REALLY want this, but I dread to imagine what a company would charge.. Kudos to you for making this open source, I'll try and get this running on my RaspberryPi Zero W =)
Have no need for this but I knew if I watched this guys vid it'd be at the very least cool, unique, awesome, informative & beneficial. So...yup, exactly what I thought.
Oh nooo I'm obsessed with e-ink and now very tempted to buy one of these things, specially the colour ones :D
I absolutely love this! Well done, I would love to have this or something like it.
First of all absolutely amazing just found your channel, I wanted to make a nice big touchscreen fot my Homeassist setup and think I'm gonna go with e ink idk why I didn't think about this sooner. The ghosting comes with every e ink display you can fix by basically flashing every pixel once in a while or have a low profile button,a capacrative button or if you screen has one a Touch function.
The legend is back!
Dang... you go all in with customizing your desktop setups now!
Must say - I'm not a huge fan of the 3D-print textures, but for what it does - this looks pretty cool!
3D printed cases, custom electronix, display modules, servers???
Can't wait to the point where you'd open a kickstarter to offer desktop productivity packages!
Always love your low-key videos, with slick designs.
This is a good project. Nice accessory. Cheers! 👍
Super cool!
This is something that I didn't know I needed. I have been interested in eink for years and have always thought it to be cool. I just never took the dive into making anything with it Looks like that may be about to change :)
Great job! 👌🏻
Loved it.
This looks great!
Can It run Doom?
It will
Yes
Yes. Maker fun duck was about to play doom on an eink price tag
This is an amazing job! I've always wanted to do something like this. For power saving you can use the interrupt pins (i think thats the term) to put the esp32 into a lower power state and watch for wifi interrupts. A bit more complex than implementing the sleep timer but well worth the final results you will see :)
Very cool and interesting stuff!
Awesome project.
David Zhang I am watching very very long time,/ thanks for uploading
Nice project
pretty freaking cool
Nifty build! Would love to see this sold as a kit.
Very neat.
Very cool!!
That's cool.
You can move everything 1/2 pixel each refresh in a rectangle pattern, that prevents ghosting for text and lines.
For wider elements like HDMI/USB i would advice redesigning the look, flipping the colors.
Draw only borders outside, not inside, then draw 2 black lines to seperate the chosen element. You can also disable numbers if not selected. Many possibilities, hard to say without seeing it first.
Both things should be enought to reduce ghosting quite a bit.
a version that showed humidity and ambience temperature alongside all that other info would be cool too. Or a to-do list or project task list
this looks fire
Thats sick man !
That is actually genius. I would actually drop so much cash on this.
So good !
I've wanted to do the same, I'll probably wait a bit more in order to get better suited displays !
This is really cool, and as somebody who runs a Home Assistant instance and would like easier access to view stats from it, quite relevant.
It shocks me that there's no good commercial ready-made product to make this kind of thing easier though; e-ink displays are highly commoditized at this point, and as you show the electronics to drive this sort of low-rate information are simple.
yay another video, also when is dream desk setup 7.0 coming out?
Great. I need to make similar one!
I would love to see an updated video on your macro pad with the changes that you've made.
For me E-ink was always the most underrated future technology that deserves more attention and research /adoption.
Nice one.
It would be so nice to do a Home assistant dashboard. Ideally that can take touch input and also lasts a couple of months off battery :) I can see myself especially monitoring my power usage as well as production through solar panels
Cool stuff, I'd love see the colored e-ink version
Awesome!
dude that's sick
Awww maaaan i wanted to buy this immediately.
he is back alleluia
Very nice! I would buy one if available in stores.
I always wanted something like this too
Very cool
Top quality content
A multicolor e-ink display would be really nice for displaying album art of a current song playing.
I have a music studio wit ha pretty complicated audio routing set up, going through many analogue boxes, split into 2 sets of monitors and a subwoofer..
I don't know, I'd really like a little display showing what is in use, the routing and maybe some information about the current volume, a slow update of the overall frequencies, current track or current virtual instrument being used.. I'm sure there is a lot of stuff that would look great and be informative.
Begging for an update on the macropad 🙏 I'd love to see how it's changed
Very Nice. I'm inspired and will Subscribe.
Great idea, maybe I can make one of those with my old kindle.
for a second, I was like; GREAT! where can I get this and as the video progressed then I realized he build this.. urgg even cooler
So Coooooool!!!
I bought one of those screens a few months ago, my goal is to build a small low power device with a few buttons that I can configure to track daily activities such as when I go to bed, when I wake up, when I eat, that sort of thing. Just a one-click data logger that will also display a little info. My biggest issue is that I hate low-level graphics libraries, and I was unable to get any of the higher level ones to run on the thing.
SWEETNESS E INK DISPLAY
3:10 You can add a refresh function to clear ghosting. Aka, change all pixels to black and then white to fix stuck ink pixels.
All e-ink devices do this regularly like every minute or so. They even have a button to manually refresh the screen.
Now that is cool. I want one. :D
That ghosting issue is definitely the worst - if that issue is mitigated or resolved, I would totally consider having something like this on my desk.
Looks like it's using partial/fast refresh too much, which may have permanently damaged those pixels. Using full refresh more often will prevent that.
You... I like you.
I need to make this.
Missed your videos, hope you're doing well! =)
Would like a step by step tutorial. This is a great idea
I see you playing Helldivers 2! For Democracy!!!
im excited for colored version .
that ghosting hurts my heart.
Making some pictures (numbers) for a clock on an M5Stack device. Wanted to see some others before I do the last parts.
OMG I WANT THIS
If a normal type that have logs but weather forecast still exist to tell of future temperature, just if people don't use it, to have logs section of the past days with limit that autoremove. Just temperature, then and with clock(about price) - point of temperature to check can be far using wires. Logs can auto-send(sync) to computer hard drive(to select on and off). Anyway it is nice because heard of water sprayer to create like a rain at area - maybe to create a witness looks like a false description.
Open source is like an angel sent from the heavens. It's literally God's gift to humanity.

Legiiiiiit af 🔥 I've been working with a lot of greyscale myself (printing single process black over backing labels), perhaps the issue is your color space? Ive could grayscale color space to be very vague and confusing. I suspect it may tie into why your display is giving you crap over the grayscale.
Cheers and happy tinkering!
