> This is the coolest thing on HN that I've seen in a minute. Off-topic, but what is up with the increased use of the phrase "in a minute", presumably to mean "in a long time", lately? I've only started encountering it in the past year. Did it get popularized by some celebrity, tv show, influencers, etc?

It's been around in slang for a few years with a few variants, e.g. "I haven't seen her in a hot minute." I think it's just filtered into wider cultural vernacular.

people have been saying "it's been a minute" to mean a long time since at least the 90s in NY

Any easy way to get started on your own version of this without needing a mic would be to pull birds seen nearby using the eBird API and pairing scientific names. Won't be as accurate as a backyard mic, but will give you a direction to start.

Also if you have old e-ink device laying around, you can likely setup BYOD with TRMNL (or just buy one https://trmnl.com/) and send the bird images as a private plugin

Thanks for speaking to the battery question; I'm very interested in how to run this kind of thing (the display portion at least) cordlessly too, especially when lipo pouches in that range are so dirt cheap.

I might be misunderstanding your comment but the display is run/powered by the board so all you need to do is provide power to the board. For e-ink it uses no power to "hold" an image, only to write/refresh (sorry if I'm telling you something you already know!). So reiterate, with a 2000mAh lipo battery I should be able to drive the board _and_ the screen for over 3 years if I only refresh it at most once every 4 hou…

Yeah no we're aligned; I have some raspis that I'm interested in doing long term battery stuff with (remote sensing and the like) and it definitely does seem like connectivity is the huge battery killer, like even if you wake up only periodically to take a reading or update an epaper display, the cost in battery just to negotiate a wifi connection and do tcpip and http things is awful.

And then you're stuck with a device that can only be communicated with when it chooses to wake up, whereas with BLE it seems you can listen for a remote OTA wake much more cheaply.

The e-ink screens linked by OP are much more interesting from a color reproduction standpoint. TRMNL devices are either grayscale or 2 colors.

We could also leave fake images aside, go outside and try to watch the birds ourselves. Maybe even let the camera inside, just looking with our own eyes. Real nature. No intermediate.

The next logical step is to have speakers for the backyard to simulate the wildlife that no longer exists.

The underlying classifier, BirdNET, is a traditional neural network and not an LLM: https://doi.org/10.1016/j.ecoinf.2021.101236

Curious if there is a similar project for dog barks.

I wanted to say that seems like a stretch but then I often find myself visualizing my best guess at the appearance, including species, of an unknown dog. It seems like size of dog and pitch of bark are negatively correlated
