TRMNL

Spent some time deploying TRMNL to my Boox Devices, the Go Color 7 and Go 10.3, some of the best ereader/eink/android tablets and turning them into TRMNL BYOD (Bring your own device). You cand find more info at Github. TRMNL have done a great job of making physical eInk devices but also open sourcing the software. For $50 you can buy a developer licence and use your existing devices to build these great eink screens that rotate in a playlist. Each plugin or recipe you add can be forked and customized. Originally for their battery powered eink screen, so it only needs to refresh every 15min or whatever time you set it too, this conserves battery as eink only needs power to refresh and fetch the screen not display the screen.

It been fun being able to not only add plugins but customize them for my screens. The Boox Go Color 7, as the name implies has color so you can make customizations to display colors etc.

In my case I used their Android App to pass my device ID and API key to the app so it can display on the device. They also have a web expereince you can use or build your own. I have tried a few from github, Terminus and BYOS Node Lite. Terminus is the most involved.

I was able to build it on this same OCI cloud server and now can serve my own TRMNL screens to my devices without any connection to TRMNL. I was able to recreate the plugins, called Extensions in Terminus.

In addition, I built plugins that utilize Apple Shortcuts. For example, the plugins use JSON, so using a Shortcut to fetch the web content from Daily Tao, it then transforms it into a JSON and uses a webhook to update the TRMNL plugin daily.

Its great fun and lots of new learnings to roll your own.
