Is it battery-powered? And how thick is it? I currently have a notepas stuck to the fridge with some magnets, if it was slim and could be powered for a while on a single charge I'd probably put it on the fridge.

Battery-powered is kind of my dream as well, but this one is wired. Removes a whole lot of complexity.

Can you post some specs about the size of the display in inches & pixels? And does it run an open OS? I recently bought an M5Paper which is a 960X540, 4.7" ESP32 e-ink display for $70. So that provides a baseline for your hardware.

The display is 7.5 inch.

Check out Inkplate. It has a 6" screen, it's programmable so can display whatever you want - not just a calendar and has an option for a plastic frame and it's only $100. They also have 10" version coming soon. Maybe you should pivot into building custom wooden frames and/or software for Inkplates.

IMO, the bezel is way way way too big for how much screen space there is. Instead of red oak, I'd suggest looking at walnut or cherry -- something with more color and a little less texture might help the screen to take focus. You could also look at separating the screen from the bezel with some kind of mat board or something (another commenter linked to an instructable that did this). I'm also not super clear on the…

The wood is actually beech, though this particular batch I got for the prototypes had a surprising amount of texture. I am planning to use lighter colors in future. Regarding your second point: I'd love to support a multitude of layout options some day.

You might want to consider making the screen flush with the front of the wood. As-is, the frame is going to case a shadow over the screen.

I'm not sure who this product is targeted at. If it's for "home consumers" then it doesn't really make that much sense as the calendar is focussed on the 9-5, while home calendars are usually more focused on the 4pm-10pm. Also bear in mind that home calendars will have multiple simultaneous appointments - Dad will take the dog to the vet appointment while Mum takes her daughter to the ballet, so it needs to be possib…

Looks like it would work well in offices to stick on the outside of meeting rooms or any kind of shared space. I don’t like it as a personal calendar.

Joan does this well today

The wood bezel is kind of ugly & cheap looking. The audience for this is likely to be tech people and users who want to show off their calendar or manage their time with calendar invites. I think this could do well with a more contemporary frame. You could market it to people as a solution to forgetting meetings; the price would have to be low enough (sub $100) to trigger people’s impulse buying. The lower the price…

There’s no accounting for taste. I’d prefer a wood frame to some kind of LED emissive plastic or metal

Except it’s not particularly nice word and the proportions are all off.

can you open that webpage in 10 in or 13 inch eink devices ? Plenty of them out there. I even watch youtube videos on mine.

Which device?

I have the same issues as everybody else (larger screen, smaller bezel, flush mount to bezel, google calendar only), but I'll talk about the copy on the site:

Under "Set and forget", "User your [...]" should be "Use your [...]". If you're anywhere near this price point, you can't have any typos in your copy.

"For the home":

> Unlike a paper-based family planner, the Invisible Calendar is up-to-date with what's in everyone's phones. Even the kids can catch a glance at the weekend - and know when to schedule that sleepover.

To me it feels like the age when kids start to really manage their own schedules is also around the age when parents give them (or let them pay for) their own phones. If everybody has a phone, what need does a shared device on a wall fulfill?

The "and for the office" block for some reason made me think that it would be neat to have it show a single day while in portrait and show the week while in landscape. Then in portrait/day mode, it takes the place of the narrow sliver I give to Calendar.app on one of my screens / lets me reclaim that screen space, and I can still see the week at a glance by just turning it on its mount/pedestal/whatever.

This would work a lot better if it were battery powered though, you might not want the cable moving around while you're turning it.

That price was at quantity '1' though, right?

Yes but even at 10K you’ll be looking at $50 per unit at best. eInk displays are expensive as fuck thanks to patents.
