Can’t explain why but all these E-Ink projects are so awesome and attractive to me. I’m surprised I can’t just buy a bunch of E-Ink style gizmos from some company to decorate my home and office. My wallet would be wide open to it constantly. Great work and congrats on this!
Earlier quoted context omitted.
People gluing together lots of stuff to making something barely-working and massively inefficient is not a new phenomenon. Unfortunately, all the "maker movement" seems to have done is encourage it more. Careful design, knowledge and learning is being discouraged in favour of superficial understanding, copy-pasting, tweaking-until-it-works. They don't want to spend the time to learn the basics. I was recently saddene…
> Careful design, knowledge and learning is being discouraged in favour of superficial understanding, copy-pasting, tweaking-until-it-works. This is like poo-pooing amatuer woodworking and saying “people should really become an apprentice first” - no one who has the education to do careful engineering is being discouraged, the field of hardware and software is now within reach of people who just wouldn’t take on any…
They are, because they think this stuff is just as good --- and it clogs the search results for those who do want to dig deeper. I often have to add "-Arduino -Maker" and a bunch of other filters to my search results to find the actually useful stuff.
Heh that's cool. It renders the calendar as HTML and then uses selenium to open up headless chrome and screenshot it and then send the bitmap to the eink display. Clever.
That is not clever. That is horrifying. You have just massively bloated your set of dependencies to accomplish something you could have done with a rudimentary GUI toolkit.

A few gotchas:
1. some of these eink boards are hard to procure as a consumer. the vendors want you to be a company
2. the driver boards are purchased separately, are definitely required, and sometimes have windows software (vs easy to use rasp-pi drivers)
3. support is often difficult or from the OEM so english-language communication can be difficult.

Check out the Inkplate - a great e-ink platform for all these projects and more: https://inkplate.io/

Rahul got oauth2 flows working to get google calendar access.

there has to be a simpler way to draw a grid. there has to.
Instead of generating HTML from calendar data, generate PS and have Ghostscript convert it to PNG.
I don't know PostScript, and based on the example code in the wikipedia article (https://en.wikipedia.org/wiki/PostScript#The_language), I was able to get it to draw some text in a few minutes.

i bought the 6" display from eink.com to build a small personal art project - an infinite scrolling procedurally generated landscape based on this project - https://github.com/LingDong-/shan-shui-inf A few gotchas: 1. some of these eink boards are hard to procure as a consumer. the vendors want you to be a company 2. the driver boards are purchased separately, are definitely required, and sometimes have windows softw…
i’ve thought about this a lot because i use a whiteboard on my fridge. i would do this if it was huge like my whiteboard. like 2ft by 3ft. then i can read each day at a glance. seeing the whole month is huge. and writing on it means it should be a touch screen i find myself wanting larger displays than is for sale a lot. i want an electric photo frame but not some 12in screen. i have great photos i want to see them 4…
There are 31" and 42" e-ink displays available, but they cost a few thousand dollars. The 42" is pretty close to 2ft by 3ft, 25" x 33".
I must have 4 or 5 old Kindles in a drawer by now, somehow. I wonder if you could hack together a grid of old Kindles to make a giant e-ink screen?
