Playing with CircuitPython and Enviro+ - Gas sensor

 The feather wing Enviro+ has different sensors in it.
One is the Gas sensor MiCS-6814.
The article covers some information about how to interpret the measurements made with this sensor.

Playing with CircuitPython and Enviro+

 

The main reason to play with Circuit-Python was to use a FeatherWing from Pimoroni called Enviro+ to develop an environmental measure tool.

Raspi calendar - HW-SW

 OK, this is my set up for a calendar display using a Raspberry Pi.

Is quite a while that I wanted to have somewhere a calendar display and was considering different solutions, then one weekend I decided to do something about.

The goal is to have somewhere (kitchen maybe) a monitor showing the Google calendars of the family.
Here some notes.
I'm assuming who is reading this article knows how to set up a Linux system, I'll not describe in details many operations.

CircuitPython and MagTag

MagTag is a new board from Adafruit based on the ESP286 and with an ePaper display, switches and NeoPixel.

Let start to see how to work on this board.

CircuitPython - Feather M0 Adalogger

The  Adafruit Feather M0 Adalogger  is a Feather family board from Adafruit that can be used to create data-logger.

Circuit-Python can be used with this board, however after loading the basic support there is not much other space for other libraries and the code.

CircuitPython

Notes about  Circuit-Python. 

On line is possible to find tons of documentation and description, this is just a my notes collection about Circuit-Python, another fast prototyping system like Arduino IDE.

AWS Cli

I often have to work with AWS on some projects and I discovered the AWS Cli tool, that allow to do lot of things on AWS from your machine terminal.

Raspberry streaming audio - notes and VLC server

Time ago I did buy and built a Pimoroni kit to have a streaming IP radio.
Is time to try to enhance it little bit and add some extra information.

A family size UV sterilizer - the electronic

At this point what is needed is a timer to control the lights and also a switch used for safety and to start the operations.
