I’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.

I 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.

For 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-cale...

CalDAV is where the money is

You think so? More important than outlook?

If 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.

Yes please! CalDAV may be an overkill, iCal (which is a "read-only" protocol) would be fine for this device.

I've started working on it yesterday :)

How much of an effort is it to get this working with webcals? I love the idea but don't use google at all...

Hi, 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

Looks 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.

Cool! What are you displaying on it? I am always adding for new use cases to add as apps to my device.

I 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.

Which todo app? Todoist?

Yes - Todoist! The screen was a waveshare which sadly degraded sooner than I had hoped.

Have 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?

I 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.

Do you sell anything bigger? I only saw the 7.5, I’d be way more interested in something like 24.

I 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.

The 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.

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

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.

Unfortunately AFAICT, Onyx BOOX still isn’t publishing their Linux kernel modification or sending source on request which is a violation of GNU GPL 2.

Yes, I'm aware of that, and it's a strike against the company.

Is 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).

You 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 :)

Ooh. Purchased. Let’s see how this goes…

what screen did you use for the e-ink part of the display/who manufactures it?

It’s a model similar to the 7.5 inch screen by waveshare
