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?
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.
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.
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.
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!
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.
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.
The burn in may be prevented by an occasional full white full black flicker like the ones in the shops do every so often or when changing screen to something else. It’s like the pulse full black and white that clears it
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 =)
What I would do is context aware todo list/information. Something like the display in the bedroom shows weather for the day, time of first appointment, critical todos of the day. But the one on the door to the garage shows estimated time to go to work, current charge on the car, location of first appointment. The one is the office would definitely show time, todo list, and calendar for the day.
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.
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.
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.
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.
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
Question, with the eink can you do partial/targeted refreshes of the screen or do you have to refresh the whole screen? A thought for the burn in would be to do an inverted image flash followed by two regular refreshes to see if that resolves it. Maybe have that run occasionally or on an external trigger (button, or api call?)
This display does support partial refreshes. I have it currently configured to do a full refresh after every 5 partial refreshes. It also does flash an inverted image during the full refresh. But I've been experimenting a lot with this display so I might have cause some permanent damage during my testing.
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.
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.
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.
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 :)
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 :)
I have had this idea in my head for a while. What about a game controller with color e-ink buttons that change based off of you playing different console games on PC. Possibly like a small display and the buttons have some type of magnifier that pops them up in the buttons if there are no small enough e-ink displays for buttons.
I would add a SENS55 to it for PPM information. someone already made a different project from separate parts, but with the Lilygo having a AIO solution, it might be even better for it.
For the images, I'm not sure what the OS/library supports but look at applying 'Dithering' to you images before you display them, sometimes they are applied to image themselves or via converting images to byte arrays. Also for the ghosting make sure to refresh/clear the display every so often should be something in the OS or library you are using.
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.
I've recently done something similar but on one of the 7-colour displays, a word of warning that the refresh cycle is horrible. With B/W display, you get a single "flash", and it takes 1-3s; with the 7-colour one, it flashes all the colours in over and over for 20-40s, and you can't do a partial refresh, so it is very distracting, and I would not recommend doing more than a couple of refreshes per hour. I'm now considering turning mine into a weather station display or a week view calendar, so it only has to be updated a few times a day.
I have an addition, for the image ghosting effect. My e-ink display came with a warning to make a whole refresh every 24h and don't let it just sit there if nothing changes for too long. So i implemented a whole screen update every 12 hours and i don't have problems. But i also have a diffenten panel. Maybe it helps 😊
Try getting rid of the ghosting by having the display quickly flash black and then white (whole screen). Some e ink phones use this for the same purpose
I wish these displays were cheaper, i find them so cool Although their prices on website look ok, still for that small display its kinda pricey especially with shipping to my country
The Latte Panda is also a full fledged x86 computer, not an lowly ARM based computer like the Raspberry Pi than can only run Linux and Android based operating system.
for the battery lifetime you can't do much with usecases where the esp32 has to stay active all the time to receive data (and update the display). I'm even surprised that 1200mAh even last for 24 hours. I'd estimate 90% powerusage is the esp32 staying active and keeping wifi up. Probably it could be increased a little if you don't use wifi, but pair the display via BTLE to your computer. Positive alongside effect would be you can pair the display to any computer and don't rely on having it connected to a specific wifi.
I wonder: could the ghosting be caused by repeatedly writing the same value to that area? If so, what about implementing something to only update the pixels that have actually changed? Take a XOR between two framebuffers and all the non-zero pixels would be the ones that have changed.
This looks so cool. btw, have you considered porting this to Spotify Car thing. They are killing it, so there will be a thousands of those about to get bricked. so if i am butchering "e-ink" part of it.
"I always wanted a low-power always-on display for data stuff" *has an entire second full machine always-on to run it I just found that funny :D it's a neat idea though & I do like these displays, it looks nice and clean and definitely feels cool being something you made yourself.
Hi David, I know this is not the topic of the video, but i couldn't help but notice that you got rid of the secondary monitor arm for the laptop. Can I ask what the thinking behind that was? You've honestly been my inspiration for my personal desk setup for years and I thought a secondary monitor arm makes a lot of sense. How do you plug in and interact with your work laptop now? Or will you pick that up in "Dream Desk Setup 7.0" one day?
*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

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.
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!

That's quite a talent, to my understanding. Being able to work with code and hardware simultaneously, and eventually making your own devices
What you built is beautiful man, I liked it
The thumbnail alone was enough to give a like. Great work and beautiful presentation
Can It run Doom?
It will
Yes
Yes. Maker fun duck was about to play doom on an eink price tag
Not if. when!
Wrong question! Can it run Skyrim?😂
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
Every time we think David has the perfect setup, he makes it perfect-er!
In addition to the beauty and appeal of the device; this video is very well put together. Bravo.
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 🙏
always come up with the fabulous ideas that inspire us to upgrade desk setup again..... always happy to see your new video updated

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.
I wish you posted more! I love your videos!

Great job! 👌🏻
Loved it.
oh man, please build and sell some of these! I could do the 3d print part myself, but the coding and hardware I'm just not savvy enough.

Okay, now the real questions:
1. How much is each of these?
2. How much is your version?

Great idea, maybe I can make one of those with my old kindle.
You could build a macro pad for a nano eink display keyed macro pad.. (tiny screens for each addressable key memorey sets)
SUPER MACRO MACRO PAD
On Android,theres a feature to prevent image ghosting. I think its done by shifting the pixels
