kindle-dash VS Inkplate-6-hardware

Instead of using a cronjob you can put the device into sleep and use the RTC to schedule the next wakeup (see [1]). This takes only very little power, as the device is only turned on for mere seconds and sleeps the remaining time.

The stopgap solution for this is pascalw's kindle-dash[1]. I set it up on my jailbroken kindle and now it displays some headlines, my google calendar events, and the weather (via OpenWeatherMap API)

This thread or this project might be what you're after. The first is a full screen browser, the second is replacing the screen saver image and going into sleep mode.

Hey HN, I built this project because last year I did a terrible job of actually taking time off work and needed a way to see just how overdue I was to take a day off.

Because so much is already automatically tracked in my calendar (e.g. the HR system adds calendar events for booked holiday), I just needed a way to query it to get the metrics I wanted.

Originally I used a Go MySQL implementation to evaluate queries but it was a bit buggy and didn’t support all the SQL I wanted. Now I’m using a full SQLite database for each user so you can really do some gnarly queries (recursive CTEs, window functions, the works).

Personally, I’m using QueryCal as a Grafana datasource to power a dashboard that’s displayed on an old Kindle on my desk (using this great project: https://github.com/pascalw/kindle-dash).

You will have to compete with much cheaper ideas like this kindle-based dashboard https://github.com/pascalw/kindle-dash

They figured out the protocol for Kindle screens and designed a platform around them. The schematics and hardware design are on github as is the Arduino software, so if you want to play around with a screen you already have then that should supply all the info you need.

The Inkplate 6 works pretty well - I am using it for my digital picture frame. The only disappointing thing for me is, that they haven't released the actual source files (Eagle, Kicad, etc..) for the hardware yet. [1]
