This would be really cool to have running embedded in a digital photo frame or wall painting.


I've built this a while back, using a previous version that runs Stable Diffusion on a raspberry pi zero 2 w:

I'm building exactly that with an eink display atm. Sadly, i can't seem to be able to build the XNNPACK stuff on my pi zero 2W in the repo...


that's an awesome idea, do you have a link to more information?


Ill write it up once it's done and post here, if it gains traction you might see it haha.

In all seriousness I can give a brief overview:

- I'll probably offload the image generation to the 5 year old intel nuc I already have as a home automation server, comfyUI in CPU mode takes 20-30 mins for a generation. Ideally it's all self contained on the Pi but that might be beyond me, skill wise.

- prompts are composed by taking time of day, season, special occasions (birthdays, xmas etc); adding random subjects from a long manually curated list; then asking gpt4 to creatively remix the prompt for variety

- i have an inky impression 7.3 inch 7 color eink display and a raspberry zero stuck onto it. Right now it'll simply download new images from the NUC every once in a while

- i like wood and i dislike the jagged 3d printer aesthetic so I'll create a frame from laser cut plywood by designing some stackable svg shapes in inkscape and sending those to a laser cutter

It works right now, functionally.

Considering that I'm painstakingly writing this on a phone with a sleeping 3 week old baby on my chest it'll be while before i have the energy to make it look like something you'd hang on your wall


Sounds awesome what’s your Twitter ?


Great idea, where every 10 hours or so it would refresh with a new image it created itself (perhaps based on a theme supplied by the user).


Not very environment-friendly, though.


Dude, we are literally using single use plastic bottles to store water for a few weeks in them.


If we're doing one bad thing already, we may as well do a hundred!


We are literally using LED lighting because it saves energy over conventional light bulbs.

And now we're going to put a screen on the wall that we don't even look at 99% of the time?


Nothing is stopping you to buy a reusable bottle.


Compared to what though?

I think it might be friendlier in some aspects than fetching an image from a server running the big the models.

And you don't have to worry about service disruptions or api keys

An e-ink display doing it should only use energy when refreshes. And you could minimize refreshes to once a day, week, etc

Less friendly than a photo of course.


Watch 5 seconds of a tv show with your big tv and you've spent that environmental cost


Why do you say that? The energy usage of inference? I would guess that the embodied energy of the digital photo frame is probably higher.


That's where $1999 color E Ink display comes into play.


There are cheaper.. but it might require dithering..


2.5A 5V is not much power, and it would use considerably less when idling.


125 watt hours for a raspberry pi to generate an image in 10 hours compared to 7 watt hours for a 440W PC to run for 1 minute.


Is this for a regular Pi . The OP post is using a Pi Zero 2.

That is big though
