Unfortunately, the soft contact covering on the back disintegrated into a sticky mess, as smooth touch does, the LiIon battery has absent flat, and the software support’s lackluster.

Thoughts you, this could possibly not be advised, as Lithium-Ion battery selection is from 3 volts to 4.2 volts and a regulator would be known as for, but [Jonatron] claims it is been doing the job just fantastic.

Ordinarily, you could just place a webserver on your nearby network and provide a web site with valuable information, incorporating code to refresh the web site periodically – but the Nook’s browser didn’t assist automatic refreshes. Not to be stopped, [Jonatron] wrote an app for the Nook’s Android set up as an alternative rooting was necessary but went seamlessly. The Android put in is old, and Android Studio for it is no for a longer period downloadable, so he utilised an more mature improvement toolkit somehow even now offered on-line. There is nevertheless a compact Python-penned webserver working on a spare Pi, conditioning the details for the application to fetch.
