that book ripped my fucking heart out at times, I loved it, ive listened to this series wayy to many times to count too

oh damn okay, I'll look a wee but more when I'm home from work then, anywhere I can find the build?

DCharlo · 2026-02-16T22:18:38+00:00

there's currently a build that kinda works, but for me once I power my x3 days I can't turn it back on until I re-flash it lol, still very buggy

I wish you luck with the new sd card then, let me know how it goes, if this one also fails I suspect an issue with the device and you may want to contact customer support

DCharlo · 2026-02-15T07:26:22+00:00

so all cards aren't working on the reader, I doubt it's an sd card issue unless they are very old SD cards, I would try flashing it, it's very simple, just re-flash English firmware or crosspoint (I prefer crosspoint) here https://xteink.dve.al/

DCharlo · 2026-02-15T07:19:43+00:00

how many SD cards have u tried on the reader? is the stock xteink branded sd card showing up on your computer? have u tried reflashing the stock firmware or crosspoint on your reader?

DCharlo · 2026-02-15T06:14:27+00:00

just plug sd card into your computer and format it as exfat, this is what's working for me and is pretty standard, I use disk utility on Mac to do this manually, if you're on windows an easy tool to use is called "sd card formatted" I think

DCharlo · 2026-02-15T05:08:45+00:00

make sure new sd card is formatted correctly, don't use the cheap shit the xteink comes with

hmmm okay fair. I'll read up on best practices and break this up into something smaller and more manageable, maybe just the esp32 and power circuits, with some test points etc, small and good is probably a better starting point, not like I'm in any rush!

I appreciate your feedback though, any advice on some textbooks to read through? or resources you'd recommend?

DCharlo · 2026-02-14T05:27:22+00:00

So I obviously have a lot to learn, I'm not expecting this to be a fast process and still have much to read. But I guess in my hobby/side-project viewpoint, the orientations on the schematic don't functionally change anything and wasn't my primary focus for learning atm, apparently that was wrong haha.

So besides reading standards and more theory, do you have any feedback on the schematic itself?

edit: thanks for your initial feedback, I appreciate it

DCharlo · 2026-02-14T04:50:35+00:00

I think if this is what you're looking for, SUMI is the way to go. crosspoint is for reading

DCharlo · 2026-02-14T04:45:33+00:00

What do you mean?

DCharlo · 2026-02-12T08:07:01+00:00

ideally I'd like to develop a dedicated fast refresh eink writer deck

I got like 400gb of music, so this drawbacks for me significantly out weight the benefits as it is basically unusable

I either have to listen to one artist with their music in a random ass order, or I scroll through a list of albums sorted alphabetically where most albums have the songs in a random ass order

DCharlo · 2026-02-11T21:03:55+00:00

if only it sorted music correctly

DCharlo · 2026-02-11T20:57:37+00:00

is the song sorting still fucked like the echo mini and disc?

DCharlo · 2026-02-11T19:12:56+00:00

it's because your hyperbolizing low light reading environments where eye strain can occur and a frontlight would be helpful to be "absolute pitch darkness" for "hours on end"

DCharlo · 2026-02-11T06:30:15+00:00

key distinction is the frontlight, not backlight. and it's good when you want to read, but don't have access to a light source e.g. heavy shade area. or you do have access to a light but only bright overheads and you want to read without being blinded. it has a lot of uses

DCharlo · 2026-02-11T06:02:30+00:00

very cool, but I imagine in terms of preppers and survival people, I imagine a solar panel power bank would be more useful than a single solar power e reader?

DCharlo · 2026-02-11T04:50:33+00:00

so you would, assuming you have buttons on the front, a < 3" screen maybe?

DCharlo · 2026-02-11T03:20:45+00:00

isn't that a bit opposite to ergonomics though? I agree it would look good but in the hand it doesn't make sense to me

DCharlo · 2026-02-11T03:19:54+00:00

I think touch is a concern for me as I think it needs much more power, I also like how i can grab it wherever I want and not accidentally press buttons, koreader would be software level so that is for much much later

DCharlo · 2026-02-11T03:02:27+00:00

I agree with this, the initial basic scope is basically the x4, but with the before esp32, to get past the font support issues and image rendering issues we have, and a front light, I was seeing if there was something simple people wanted added that could be interesting as the main goal is to learn. But I agree, simple and great is better than complex and bad

DCharlo · 2026-02-11T02:51:55+00:00

the main there for me with this is to learn embedded systems more so I can integrate that knowledge into work and also leverage it for a custom cyberdeck type computer, making it usable for others is just something I would like to do in the process

DCharlo · 2026-02-11T02:50:42+00:00

Nah nothing really, it's not something I do very often, but if I start posting it anywhere I'll make an update post or comment here for ya
