It’s true. Large eink displays get expensive really fast.
I went with a 7.5 inch display for the eink calendar / smart display that I am selling.
I am definitely feeling the limitations, but there is still a lot you can do at that size.
Have a look: https://shop.invisible-computers.com/products/invisible-calendar https://shop.invisible-computers.com/products/invisible-cale...
And maybe once the business grows, I’ll have the volumes needed to get better prices on the bigger displays.
- mmh0000 3y agoI’ve looked at your product multiple times and every time I think I wanna buy one. Then I go to the webpage and I see that it only works with Google which is not what I use so then I get sad and leave. I’d buy one in a heartbeat if there was support for iCalendar or other common/open standards.
- konschubert 3y agoI have started working on more calendar integrations now. If you write me a short mail at info@invisible-computers.com and tell me what integration you need, I will make sure to let you know once it is out. In the meantime, there are often ways to sync other calendars (also iCalendar) with google calendar. It’s a bit of a detour but it might just work.
- ekianjo 3y agoCalDAV is where the money is
- konschubert 3y agoYou think so? More important than outlook?
- abawany 3y agoIf you get CalDAV working, you will support a ton of non-gmail/outlook providers for 'free' including those that are self-hosted. For e.g. runbox, mailbox.org, mailo, etc. all provide caldav to their users - some of these also support exchange but in my 'research', caldav was universal.
- imp0cat 3y agoYes please! CalDAV may be an overkill, iCal (which is a "read-only" protocol) would be fine for this device.
- konschubert 3y agoI've started working on it yesterday :)
- jfil 3y agoFor reference, here is a clunky way to sync Outlook calendar events with Google Calendar, using Microsoft Power Automate (which comes free with many Business accounts): https://jacobfilipp.com/sync-outlook-calendar-to-google-calendar-using-microsoft-power-automate/ https://jacobfilipp.com/sync-outlook-calendar-to-google-cale...
- anoncow 3y agoLooks good. I made one using a waveshare screen and a raspberry pi zero. It cost almost the same as your retail price, but it didnt look this good.
- konschubert 3y agoCool! What are you displaying on it? I am always adding for new use cases to add as apps to my device.
- anoncow 3y agoI was displaying a list of tasks from a Todo App via API, clock and calendar, and times in different cities where my company had offices. Showing a clock ended up being bad for the display as it quickly degenerated. You calendar view is great.
- konschubert 3y agoWhich todo app? Todoist?
- anoncow 3y agoYes - Todoist! The screen was a waveshare which sadly degraded sooner than I had hoped.
- bennetthi 3y agoDo you sell anything bigger? I only saw the 7.5, I’d be way more interested in something like 24.
- konschubert 3y agoI just don’t have the volume right now to get good prices from manufacturers on any bigger displays. I’m looking into 10 inch displays right now, but they are already significantly more expensive. At some point it just drives the price of the end product up too much.
- dredmorbius 3y agoThe largest devices I'm aware of are E-ink displays. Onyx produces the Onyx BOOX Mira Pro, 25.3" diagonal, based on the E Ink Carta, 25,3", resolution of 3200x1800 dots, 145 ppi, 16 shades of grey. <https://onyxboox.com/boox_mirapro https://onyxboox.com/boox_mirapro> Note that the pixel density is markedly lower than other e-ink devices. For smaller devices, e.g., the Poke 5, DPI is more than double at 300 dpi (comparable to a laser printer): 6", E Ink Carta Plus, 16 shades of grey, 1072 × 1448 dots, pixel density - 300 ppi <https://onyxboox.com/boox_poke5 https://onyxboox.com/boox_poke5> Granted: with increased viewing distance, resolution can fall somewhat, but given that areal density falls as the, well, square, this is 4x lower resolution. The Mira Pro runs an eye-watering $1,750, further impeding the viewing experience. Given price trends on other E-Ink devices, I'm pretty sure that's all but entirely driven by the display cost itself.
- toastal 3y agoUnfortunately AFAICT, Onyx BOOX still isn’t publishing their Linux kernel modification or sending source on request which is a violation of GNU GPL 2.
- dredmorbius 3y agoYes, I'm aware of that, and it's a strike against the company.
- theK 3y agoHow much of an effort is it to get this working with webcals? I love the idea but don't use google at all...
- konschubert 3y agoHi, I’m about to find out, since I am working on adding support for it :D If you want I can let you know once it’s done if you send me a short email to info@invisible-computers.com
- starman12980 3y agowhat screen did you use for the e-ink part of the display/who manufactures it?
- konschubert 3y agoIt’s a model similar to the 7.5 inch screen by waveshare
- QuinnyPig 3y agoOoh. Purchased. Let’s see how this goes…
- iglio 3y agoHave you considered using multiple of the current displays together in a single product, presenting them as a single view to the user? Does that help with the pricing?
- konschubert 3y agoI think that's something the display OEM would need to do. Once I get the displays, they already have bezels. That won't look good as a 2x2 grid.
- aranke 3y agoIs it possible to make a black or silver frame (ideally with thinner bezels)? If so, I'd gladly buy one (wood does not fit in my current theme).
- konschubert 3y agoYou could take the wooden frame and paint it black maybe? And maybe pair the stand black as well, or use another stand from Amazon? I can send you the disassembly instructions (email me at info@invisible-computers.com) and then you can disassemble it before painting. Or if you want I can paint it for you, but I would have to charge a bit extra :)
