I went down the hole of installing Linux on my phone (Samsung Galaxy S7). The
easiest path is compiling and installing UBports,
some people have heavily started the process but it is still a work in progress.
This is the first part: step by step description to build and boot the system,
with helpers scripts to setup the system once flashed.
Small hacky script to set regular temperature changes in 3D printer gcode, to
easily use “Temperature towers”.
nfcAudio is an MP3 player, with audio files selected thanks to an NFC tag placed
on top of it. I build this two years ago for my kid so he can play by himself
his preferred nursery rhymes and songs, it is still used at least once a week
It is powered by an ESP8266 to play audio from a remote server, an I2S DAC
driving the speaker and an NFC reader. Thanks to WiFi we can use it to play
local files or any webradio stream from the Internet.
For the fifth year of this blog, I switched from Ghost to Hugo. I used to like
Ghost as a small and simple tool when I started the blog.
Ghost is now a powerful content management system but far more complex than the
simple tool I am looking for, even writing a full post in markdown became less
and less easy over the years. As I do not need fancy stuff and like the
simplicity to pre-generate the pages and drop the HTML files somewhere I looked
at static site generators, I gave a try to Hugo and I liked it. Let’s see what it can
do in production but I already enjoy to avoid Ghost, Node, and NPM maintenance :)
I had to move my previous Wireguard VPN + Pi-hole ad blocker to another server,
but this time I was not able to expose Pi-hole DNS port (53) to the host
machine. It was also better to have Wireguard VPN inside a Docker container…
so I did!
As a reminder, Wireguard is a stateless and easy to configure VPN: share a pair
of public keys between the client(s) and server then you are good to go!
Moreover, stateless is great when used from a phone as there is no power-hungry
keep-alive like OpenVPN, nor reconnection time when switching from Wi-FI to 4G.
