Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: E-Ink Day Schedule
https://www.invisible-computers.com/invisible-calendar/image...
Two:
https://github.com/Invisible-Computers/image-gallery/blob/ma...
Both of these require rendering the content via an HTTP endpoint and both of these currently still require the content to be proxied through the device backend.
> I can buy an ESP32 e-ink screen and run esphome or any of several other open source projects and put a piece of wood on the front of it, too.
Yes, you can! And if you do this, you have absolutely no need to use my e-paper smart screen.

E-ink is so Retropunk
I am hoping to add third party apps, that's why I have created the API for 3rd party apps:
https://github.com/Invisible-Computers/image-gallery/blob/ma...
But right now, I understand that building an app for my platform is
a) more hassle than just pointing to a URL
b) limited upside, because the audience that you can charge for a subscription isn't very big yet.
However, I think that a good app could generate its own audience (aka drive ppl to buy the displays) and then make money by charging them a small monthly subscription fee.

I wasted $855.77 on Google Ads and got my ads banned 5 times
I'll ship within Europe as soon as I have bootstrapped the 7000 Euro necessary for CE certification.
In terms of openness, there is this:

and this:
https://github.com/Invisible-Computers/image-gallery/blob/ma...
I also want to make the esp32 controller itself more hackable in future, but I don't want to promise anything because that's quite a lot of work for me.

Ask HN: Any Hardware Startups Here?
Here is the API description:
https://github.com/Invisible-Computers/image-gallery/blob/ma...
And here is the sample app:

Admittedly, I am not the greatest technical writer, but I compensate by being pretty responsive. :)

A WiFi color eInk picture frame
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...
The API doesn't require any special knowledge about e-paper displays, it just expects an image URL in the correct resolution and will then render it to the display.
You can buy the display off the shelf, and if you are interested in building an app, contact me at [email protected] for a developer account :)
Feel free to go to town on it :)

What Can We Learn from Barnes and Noble's Surprising Turnaround?
>I really wish I could have an e-reader, but again, I don't want to spend money on things that will lock me into a single vendor indefinitely and might just arbitrarily go away.

This may be up your alley.

Are there any small form factor readers (a third the size of a smartphone or smaller)?
It's not a commercial off the shelf product, but the Open Book uses a 4.2" screen. There are other devices you can find on places like AliBaba that are kinda small. However, in general you won't find a name brand commercial ereader under 6" that isn't ina phone body. There were a couple at 5" back-when but the industry really settled on 6" as the common base size.

GitHub Code Search (Preview)
This is very useful to see examples of how people have used APIs that are either poorly documented or not at all. Or even that are well documented, really. Going from docs to code is not always straightforward.
To give you just one example, recently I've been using it to find how people have written code to interface with e-ink displays. I usually have the datasheet which lists all the commands the protocol support, but building it all into a valid startup sequence of ~20 commands to activate the display is left as an exercise for the reader.
So the docs will look like this: https://www.waveshare.com/w/upload/6/6a/4.2inch-e-paper-spec...
And what I need is a sequence like this: https://github.com/joeycastillo/The-Open-Book/blob/5c5054c58...
