Is there anything like this that can wake the Kindle up, get an image, and then sleep it again? I have an old Kindle that I want to show stuff on, but I don't want to keep it plugged in all the time.
> wake the Kindle up, get an image, and then sleep it again
This is basically what I'm doing with this project. I tested the client by getting a dummy image initially. This line in the code puts it to sleep for x-duration. The kindle runs for ~2-3 weeks on a single charge.
If you just want to test if your image works, I've created a handy script for testing. It downloads the image, displays it for 20 seconds, and reverts the Kindle back to its normal state.
I work on e-paper displays. Are you looking for something built with a Kindle?
This project of mine is similar to what you described with a power down mode. The power down and wake up can be automated. I'm looking to build a small business around such projects. Not sure how viable it is.
I made some stuff of mine for that display too, but the easiest way is to just use TRMNL's firmware, as it supports autoupdates and a few other nice features.
That's beautiful, thanks for sharing. I was wondering what may be the best way to do frames. Custom frames, here in Singapore, are a bit expensive relative to the rest of the parts.
3D printing is one good way, the other way I used is just to get a frame from IKEA and 3D print the inside white bit to my exact dimensions, which worked beautifully.
I should post that build too, with some photos, I really like it.
