We don't have anything to nag us, but the grandparents and aunts and uncles all have Nixplay[0] frames that we regularly update with photos of the kids. [0] https://www.nixplay.com/

That's cool. Do you know if these are hackable at all? Or do you have to use their service to push pics?

That is the key on a product like this. $5+/mo for a service to occasionally update photos on a device that is already sold at a profit is robbery.

If anyone wants to make a similar project, there is a great Rust API to most of the Waveshare displays[0] (I added support for the display mentioned in the article, 5in65f).

I also made a project[1] with it that generates art using a gameboy emulator and some static images and other transforms to show on the display.

Impressive DIY project. Still, as a person with no intention to DIY, I’m looking forward to a simple eink photo frame product. Crucially, something that works out of the box and is shipping now (so: no Kickstarter, no need to write custom scripts, etc).

Might be waiting a while. What are you willing to pay for that product? Personally, I'd like to see more products that repurpose old phones and tablets while scratching that "new object" itch.

Hard to set a price without knowing the details (screen size, UX, etc). Roughly, for a well reviewed product like this, I’d be willing to pay something in the iPad mini - iPad pro range.

Repurposing here would mean regular screen, i.e. not eink; I’m not interested in that.

Another great option is Pimoroni's combo eink display + pico w https://shop.pimoroni.com/products/inky-frame-7-3?variant=40...

How is the battery life on the Pimoroni? I've used RPi Picos before, and I love working with them, but IIRC they are comparatively power-hungry, even in deep sleep.

Power consumption of the Inky Frames in deep sleep is minimal as power to the Pico is cut completely. An RTC is kept powered to wake up the Pico on a schedule, or pressing any button will wake up the board too.

Wow! There's a dynamite product in here that pairs a daily nagging app and one of these displays so that people are reminded to take a new picture, ever day, and have it show up on someone's (or all subscribed) photo frame. I'm thinking, like, "take a photo of the kids so it will show up on Grandma's frame" kind of functionality. Though, obviously, it would also be used for porn, so there's a market there, too. Anywa…

If the grandparents enjoy getting physical mail and like hard copy photos to have around the house, then https://nanagram.co is a good option[1] You just text in your photos and they printed and shipped once a month. We use it for my mom to send baby photos and she loves it.

[1] Full disclosure: my older brother built this service, but I don’t have an affiliation other than being a proud brother and happy customer.

"... With only 7 colors and a refresh time of about a minute ..."

Ouch, even worse than expected. The project is interesting, but I'm totally unimpressed by these numbers; I wouldn't pay a premium for a sub par display that is slow as a dead sloth. A traditional LED screen plus some tricks to save power would make a much better picture frame IMO. I would for example use a PIR/microwave sensor (they're cheap!) to detect when someone is approaching or stationing near the picture frame to bring the CPU back from sleep and turn on the display and backlight. It would never reach the same almost zero current draw of a epaper screen, but the quality gain paired with the lower cost would probably make it a viable alternative.

This display offers a simple API to build applications for it: https://shop.invisible-computers.com/products/invisible-cale... https://github.com/Invisible-Computers/image-gallery/blob/ma... It's black-and-white, but dithering allows to show surprising detail and it brings its very own old-school aesthetic.

I think it’d be a little more honest if the first sentence started with „I offer a display with a simple API“. https://www.invisible-computers.com/imprint.html

It's not like I am hiding it? I just didn't think it mattered in that context that this is me.

But I see your point.

Is this for sale still? It shows sold out on the site.

I will hopefully have stock again soon.

That frame makes it look like ancient technology rather than 'picture frame'.

I know, right? What a hideous frame. It somehow makes the screen look worse! I smile fondly and lightly jab at hackers complete lack of concern for aesthetics.

Puh, that's harsh. But you are right, the frame is too wide. I am trying to make it narrower.

Honestly I considered trying to hack one but just never managed to put it on the schedule. Early models had some quirks but now they're reliable enough that I haven't found any pain points that would compel me to open one up so if I ever get around to it it'll be just for funsies.
