Introduction

This script is basically a workaround for the bug in zbarimg that it cannot read QRCodes with the Swiss Cross in them (as every QR Bill in Switzerland has). See https://qr-rechnung.net/#/

Writeup/ticket for my problem: mchehab/zbar#216

Usage:

Introduction

Install Raspbian Lite on an SD card
Set up InfluxDB
Create a logIt script to log data to Influxdb
Set up 1wire bit-banging (GPIO 4)
Create a getTemperature script to read temperatures from a connected sensor
Create a looping wrapper that fetches temprature from sonsors, then logging it to the database

This small writeup is meant to show that it is quite simple to write a data logger by relying on "unix style" programs that do one thing only.

Introduction

Use slack_pipe to just send quoted text through a pipe to slack.

Example:

echo arne | ./slack_pipe

Introduction

An ansible inventory file that is set as executable will be executed instead of read as a normal inventory. This is called Dynamic Inventory.
The stdout of the executable should be a JSON file

The dynamic inventory will be called a number of times.

Once to get a list of hosts
Once per host with the option "--host HOSTNAME" - to get eventual host variables

Rökgenerator

Faktorer som påverkar förbränningen

Rökgeneratorns diameter och form
Rökrörets dimension
Luftpumpens kapacitet/Venturi-rörets luftflöde - spelar stor roll för luftflödet till glödbädden
Venturi-rörets utformning och dimension
Venturi-rörets placering för optimal venturi-effekt
Storlek på hålen i gallret på glödbädden, påverkar huruvida askan faller igenom när ett spån är färdigbrunnet

/etc/network/interfaces

source-directory /etc/network/interfaces.d
