Kongduino kindly sent me a WisDuo RAK3272s few weeks ago, it is a a breakout board for RAK nice module (RAK3172) around the STM32WL5 system on chip from ST. Let’s see how to use STM32 CubeMX to generate the initialization files and the LoRaWAN stack, then setup Visual Studio code debugger.
I recently bought a Sonoff Zigbee 3.0 USB Dongle Plus from iTead to use it with Home Assistant.
While it worked out of the box, the update itself was not complicated but you
have to find the right tools…
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.
Notepad of a tinker, maker, hacker or whatever you call it :)
