Now I have a reason to get reMarkable :)

Don't. The USB C port is poorly designed and will break at the drop of the hat, leaving you unable to charge the thing. And the company won't do anything to help you.

I’ve had mine for nearly five years, USB charging continues to work.

A fun experiment, and cute if not for the lag. A full 14 seconds between the pen stopping writing and the result, What I'd find interesting is the trace of that 14 seconds. How much is the Remarkable processing, how much is the claude transcription, how much is the let-go start-up / processing, etc.

The author mentions that in the blog. The majority is the delay of the updated file actually being written to disk by the device. The author did not find a solution to trigger file write earlier/more frequently.

They said that, but they described it as "Several seconds", so I assumed there was plenty of other lag too.

Searching the article again, I see in the FAQ:

> Xochitl takes approximately 12 seconds to update the notebook on-disk

12 definitely isn't "several" in my understanding, but regardless, I guess there's little the author can do then.

Amazing! I'd recommend using PaddlePaddle OCR models if you want to make your handwriting conversion local, it's definitely fast enough. Probably faster than the Sonnet call.

I tried the model on your handwriting and it worked great. My handwriting is bad enough that it doesn't work :)

Ok this might be the coolest thing I've seen all month. You must be a Recurser, right? This is so very Recurser.

I have no idea who or what a Recurser is, but I guess I’ll be checking it out. :D

I’m guessing GP means a participant of the Recurse Center[1].

I find getting stuff up on the rM2 screen a hassle. The challenge comes from the way the e-paper works. To turn a pixel from white to black (or vice versa) it needs multiple actual frames. The pixel data must also be packed in a specific format. Instructions for how many frames a single operation requires are coded in a wbf[0] file, which comes included with the OEM firmware. The most commonly used approach is hookin…

My reMarkable is still stuck on a super old version (v3.3 I think), precisely because of xochitl being closed source and there's no stable and efficient way of driving the display. It's super sad because I would love to have much more things appearing on my tablet yet I cannot develop reMarkable apps easily. I'm not talking about browsers, but more like my Linear TODO list, calendar, etc., so I don't have to reach for my phone.

I really want to try for further reverse engineering of xochitl now that I've heard those AI tools have gotten so good at doing it.

Man I really wish one day I could run mainline Linux kernel on this tablet with the display just works.
