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:

  "fullscreen": true,
  "autoStart": true,
  "websites" : [
    {
      "url" : "http://com-icinga-l01:3000/d/JGY36E_mz/skype-and-lucs?orgId=1&refresh=10s&from=now-6h&to=now&kiosk&comment=sfb_lucs",
      "duration" : 40,
      "tabReloadIntervalSeconds": 300
    },

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

• 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
