I kind of wrote something for this a few years ago: https://github.com/rberenguel/glancer [edited a fat-fingered copy-paste]

The use-case is technical videos (like from conferences) I’m interested, but not enough to invest 20-60 minutes.

Haven’t used it in a few months so the yt-dlp commands may need updating.

Sadly getting a 404 here–maybe this is a private repository?

I think RBerenguel intended https://github.com/rberenguel/glancer

Thanks, I fatfingered the copy paste on my phone :/

Not exactly what you want (I want the same) but I wrote this to scratch that itch: https://github.com/rberenguel/PiWrite

This is very cool! You're right that not exactly what I'm looking for, but great to see nonetheless. I did see on the product Q&A page[0] that one of the questions was about plugging in a keyboard. The answer was:

"You can connect a wired keyboard to the Palma via a USB-C to USB-A OTG Adapter. After that, you can type in the Notes app and third-party word processor apps. "

Which sounds promising!

That certainly looks great, and has an excellent form factor too

It’s not as bad as I expected before trying the project. You can try with SolarWriter (which is easier to set up than this weird thing I did) to get an idea. I consider it “mechanical typewriter” level. For me, good enough.

I wonder whether USB Network might be an option to reduce the latency a little. L

Plus then keeps the Pi WiFi free for regular use rather than as a private AP network.

The Kindle can’t handle USB networking, so it wouldn’t be a viable option. The private network is only needed if you are not in a WiFi capable area: at home I use it without AP

Historically, at least, USB networking was pretty straightforward to enable on a jailbroken Kindle.

I don’t have the Folio case, but I have a Remarkable 2 and the screen refresh time is not as nice as the Paperwhite by quite a margin. I had actually managed to plug a USB keyboard to the RM2 (can be done, you need to tweak several things and power it) and the experience was quite “meh”. Also on a personal note, I prefer the form factor/size of the Kindle for this. The RM2 always feels flimsy!

That seems strange. You can use the pen on it, and the screen changes near instantly. There is not much of a lag. I would think that typing would be almost as good.

Edit: I see this guy typing here, and the latency doesn't seem horrible. Probably equivalent to the latency of an actual mechanical typewriter. https://youtu.be/R8VG6dQkTwI?si=_YWK7-fLw7MhS1Vv&t=2226

Of course, this folio keyboard looks horrible.

Writing latency on the RM is good: for typing is very likely to be well above OK… as long as you don't have to scroll the text/screen. Because page turning latency/refresh speed is quite bad. No "this is shitty bad, gimme my money back" but slow enough that it makes skimming impossible and normal page turning slightly annoying (worsened the larger the PDF). A similar kind of latency can be seen particularly when using the cut/move tool, for example.

To be fair when typing (a few minutes after the time in the video you shared) the latency for refreshing the screen does not seem that bad. But they keyboard looks annoying to use… I way prefer having a full choice of keyboards (aside from the fun of having written the code of course).

Typing latency on my contraption is pretty similar to what can be seen in the video, maybe slightly slower but not by much. Since two weeks ago I have written several drafts of blog posts (while I added some features that were needed, or fixed some annoyances) and it is usable, although I miss adding a "read mode" (scrolling via cursor is slow, and I have not added `:num`, `gg` or `G` yet which makes reading what you have written not great.

I have always eyed similar solutions, but getting root access to the Kindle has been getting more convoluted each time: I always chose to not try to avoid being a few days without reading if I bricked it. This is one of the reasons why I wrote this: should work as long as the Kindle has a decent-ish browser.

I did this, and to my surprise rooting it worked first time. Usually this sort of thing takes up a whole weekend of problem-solving.

Still, I used a second-hand Kindle, not my main one, just in case. You should be able to find one dirt cheap.

I’ve been there, too. I don’t feel like writing much here, but drop me an email if you feel like it (it’s on my profile).

I love my “old” Inky Impression, just to add some positivity. Just a few days added some new images and posted pictures on Twitter: https://twitter.com/berenguel/status/1662857260043829250

Back when I was a customer (before Photon was released, also during) they had a very good tuning, in the order of around 2x faster for the workloads we had at the time (very large graph computation and a “simple” filtering)

I’ve found my VP (which I like a lot though) dries up very quickly. I recently got a Lamy Dialog and it behaves way better (and even though it looks bulky it is a joy to use). For more “casual” (throw-in-the-bag) I really dig the plasticky Pelican Twists (they feel extremely comfortable, I have 3 or 4) and a trusty Kaweco Liliput in brass I always carry on my backpack.

The co-author of the article linked has a very "fun" book on how to better draw on whiteboards, particularly for topology: https://link.springer.com/book/10.1007/978-0-387-68120-7 His main example in the book is showcasing the sphere eversion.
