Hacking an old Kindle to display bus arrival times
- hex4def6 - 3056 sekunder sedanAs someone who worked on kindle power consumption many years ago: One of the (by far) biggest consumers of power is the WiFi connection. It has to wake up and respond to the AP in order to not get disconnected every x seconds.
Off the top of my head, I think 'on' average power consumption was ~700uA without wifi, and about 1.5mA+/- with Wifi. This is from over a decade ago, so my memory is fuzzy though...
Obviously, page changes used relatively large amounts of power. I don't recall the exact amounts, but it was 100s of mA for seconds.
There is also an "every x pages, do a full screen refresh (black to white)" to fix up the ghosting issue that the article writer saw.

I did the same last year and had lots of fun in the process.

- michaelbuckbee - 11652 sekunder sedanI love using Kindle's as single purpose tablet/interfaces/displays. I'm the weirdo who actually prefers the LCD displays vs eInk and it's incredibly easy to set Kindle Fire's into dev mode which lets you display a webpage, never turn off while connected to power and never show ads.
You can regularly find the Kindle Fire HD10s for ~$40

The Kindle browser is surprisingly decent, I made Claude Code generate an RSS feed reader compatible with the Kindle browser, with the ability to read full articles (for those feeds that require you to visit the website), and download articles. It also supports Reddit and Google News RSS feed. This is my new favorite way of browsing the internet.

For a defunct startup, I built this exact thing as a product for coffee shops:
