e-ink is so much fun, especially when combined with ESP32 or BTLE boards. I currently have 4 around my house displaying book quotes that I've highlighted in KOReader and they bring me joy each time I see them. They are simple and do one thing very well. I just got and setup a BTLE e-ink driver the other day and according to my calculations it will last _years_ on a single charge (2000mAh) even with multiple refreshes…

Years on a wall mounted eink screen sounds super interesting. What are you using for the power delivery/battery side of that setup?

Here are the parts I bought, I'm still getting it all setup (I have my pictures displaying, working on designing the 3D printed case now, and testing it all) but according to OpenDisplay's calculator [0] I can expect 3.4 years if I refresh the screen once every 4 hours (and currently I'm doing closer to once a day to mimic my ESP32s which need deep sleep and once-a-day refresh to get even month/months of battery on a charge).

Screen: 7.5" Monochrome eInk / ePaper Display with 800x480 Pixels (https://www.seeedstudio.com/7-5-Monochrome-ePaper-Display-wi...)

BTLE board: XIAO ePaper Display Board(nRF52840) - EN05 (https://www.seeedstudio.com/XIAO-ePaper-Display-Board-nRF528...)

Battery: 3.7V 2000mAh - (https://www.amazon.com/dp/B0FR9GH966)

Picture of it all assembled (no case yet): https://cs.joshstrange.com/zJFvGGPB

The image rendered to the screen is coming from a little service I wrote that renders a book quote it pulls from BookOrbit which syncs with KOReader (annotations, progress, etc). My plan is to set up one of these one each bookshelf/series rotating quotes I highlighted from the series.

Here are 2 ESP32-based screens I have, the one on the left is a an all-in-one [1] and the one on the right I printed the case from the TRMNL DIY kit from SeeedStudio [2]: https://cs.joshstrange.com/knk4Ns2h

Right now only the BTLE one is running OpenDisplay (the other two are semi-managed by HomeAssistant ESPHome) and all the devices are in HA for controlling them, though the ESP32's all deep-sleep for saving battery so I can can't "push" stuff to them like I can the BTLE one.

When it does run out, are you able to replace the battery? Or is it something way more painful than that?

While I love this idea generally, the scope of the use of generative AI for artwork is too vague for my comfort. The README.md mentions that "no art is AI-generated, though some has been retouched with AI." Superficially, that sounds mild. Some of the other closely-related projects, however, use different verbiage, or none at all. For those of us with ethical concerns around generative AI application to artwork, much…

Very cool!

I can't help wonder what this would look like for humans. Imagine, set one of these up at a party and it has the means to identify anyone on the invite list. When it hears the person it displays a photo, brief bio, and relationship status.

Cool project! On a side note. How do people deal with all the ugly mess birds cause in such settings? I'd love to have such thing but seeing all the white stuff on glass door does not really feel fun to me overall.

What do you mean specifically? These birdsong analyzers are sensitive enough that they do not rely on setting up a feeder. It’s obviously dependent on where you live, but in the Nordics, living outside city centres is good enough for both background noise and birdsong from nearby trees/parks/forests. Privacy matters aside, setting a mic up on a balcony or window is enough. Another solution is feeding data from a cheap security camera with a mic through wifi. This way the camera can stay outside in different weather, it’s not super close to you actual living area and splitting audio from the RTSP stream should be relatively easy to be analyzed by BirdNET.

It's a rechargeable battery, I just plug the board in (USB-C) and it charges the battery.

What is the ethical concern in this use case?
