Audio switcher

Doing my work from home via Jitsi (Jabra headset) and Listening to music on my speakers. Sometimes i want to switch output. For example spotify on my headset.

Using below code, i can easily switch between output sinks.

#!/bin/bash

if [ -z "$1" ]; then
    echo "DEVICE"
    pactl list sinks | egrep "^Sink|Description" | sed 'N;s/\n/,/' |sed -e 's/\t/ /g'  | cut -f2,5- -d" "
        echo "APPLICATIONS"
    pactl list sink-inputs | egrep -ie "^Sink|application.name" | grep -v "\-application-name" | sed 'N;s/\n/,/' | sed -e 's/\t/ /g' | sed -e 's/  / /g' | cut -f3,6- -d" "
    echo "Usage: $0 APPID DEVICEID" >&2
    exit 1
fi

pactl move-sink-input $1 $2

It shows output devices, and applications which are using audio sinks.
Just match them up.

Gluster testing with docker

GlusterFS (Gluster File System) is an open source Distributed File System that can scale out in building-block fashion to store multiple petabytes of data.

Below is a test environment which creates 5 docker instances, which represent 5 gluster servers.
This was for test repairing our work gluster.

First install gluster and pull a image: docker pull gluster/gluster-centos

for f in 1 2 3 4 5;
do 
echo "$(docker exec -it gluster_${f} ip a s | grep 172 | awk '{ print $2 }' | cut -f1 -d/) gluster_${f}"
done

Laser engrave tools

For my winerack i engraved some wooden panels.

When doing so, i needed to fix the height of the engraver to get the focus of the beam right.

At start i removed all Z positions from the GCODE file after calibrating. Later i used a script wrote that fixed the height setting to 110.

#!/bin/bash
# Usage: confirm height focus at 110
# ./scriptname filetofix.gcode
myz=110
cat "$1" | sed s/Z1/Z${myz}/g | sed s/Z6/Z${myz}/g > "fixed.$1"

Another tool i made is the one below, it takes a GCODE file, calulates where the borders are (min/max x and y)
And sets the FAN2 (laser intensity to a minimum)
After that it generates GCODE to draw a box wherein the to be engraved object is made

Now you can run the GCODE file multiple times to position it on the wood to you can get the minimum of spoils.

#!/bin/bash
# Usage: scriptname file.gcode 
# It wil create a pointtest file for test running
myz=110

Wacom tablet doesn’t behave

Changed some code controlling my wacom drawing tablet.
I use this one to draw Art, diagrams and touch up photo’s.

When using multiple screens, i had the problem it would stretch the draw area over multiple screens, streching the ratio. Or it took the work screen to work on.

#!/bin/bash
# using xinput here, check post about two mouses/keyboards on one machine

# Use xrandr to check names check 
MONITOR="DP-1"
PAD_NAME='Wacom BambooFun 6x8 Pad pad'

#undo
xsetwacom --set "$PAD_NAME" Button 1 "key +ctrl +z -z -ctrl" 
xsetwacom --set "$PAD_NAME" Button 2 "key e"
xsetwacom --set "$PAD_NAME" Button 3 "key h"

ID_STYLUS=`xinput | grep "Pen stylus" | cut -f 2 | cut -c 4-5`
xinput map-to-output $ID_STYLUS $MONITOR
ID_STYLUS_2=`xinput | grep "Pen eraser" | cut -f 2 | cut -c 4-5`
xinput map-to-output $ID_STYLUS_2 $MONITOR

exit 0

Most of the times i use Krita and Gimp.

Domotemp – domoticz temperature floorplan

For my home automation i’m using Home Assistant and Domoticz.
All 433Mhz Temperature/Humidity are connected to a RFXcom device on two domoticx instances. (Master slave construction)

I’ve made a php script and a bash script to draw all sensors on a floorplan in realtime.

There is also a cron running which takes a snapshot of the generated image every 5 minutes.
These images are being converted to MP4 and animated GIF to have a timelapse with all temperatures displayed on a floorplan.

An obfuscated view of the floorplan

The circles are where sensors are placed.
Colors are from blue till red, representing the heat.
In the center is the measured temperature value.

The (shortened) PHP script: (index.php)

<?php
header('Content-type: image/png');
// This is the floorplan empty ..
$png_image = imagecreatefrompng('plattegrondenmerge.png');
$white = ImageColorAllocate($png_image, 0, 0, 0);

$max = 40;
$min = -10;

// living
// getstate is a bash script (see below which gets the values from domoticz using curl) 
// 840 is the domoticz idx
$temp840 = shell_exec('./getstate 840');
// A gray circle will be drawn if the temperature age is > 500 seconds
$age = shell_exec('./new.sh 18 840 500 >/dev/null || echo gray');
// location of circle
$start_x = 950;
$start_y = 760;
$line = $temp840 + 10;
// get x-th line from colors
$colorfromlist = shell_exec("tail --lines=$line ./colors2 | head -1");
if(strpos($age, "gray") !== false){
 $colorfromlist = "128,128,128";
};
$colors = explode(",", $colorfromlist);
$color = imagecolorallocatealpha($png_image, $colors[0], $colors[1], $colors[2], 50);
// draw circle
imagefilledellipse ($png_image, $start_x, $start_y, 175, 175, $color);
$start_x = $start_x - 70;
$start_y = $start_y + 15;
// add text
imagettftext($png_image, 24, 0, $start_x, $start_y, $white, './verdana.ttf', $temp840);

// winecellar
$temp840 = shell_exec('./getstate 839');
$age = shell_exec('./new.sh 18 839 700 >/dev/null || echo gray');
$start_x = 560;
$start_y = 840;
$line = $temp840 + 10;
$colorfromlist = shell_exec("tail --lines=$line ./colors2 | head -1");
if(strpos($age, "gray") !== false){
 $colorfromlist = "128,128,128";
};
$colors = explode(",", $colorfromlist);
$color = imagecolorallocatealpha($png_image, $colors[0], $colors[1], $colors[2], 50);
imagefilledellipse ($png_image, $start_x, $start_y, 175, 175, $color);
$start_x = $start_x - 70;
$start_y = $start_y + 15;
imagettftext($png_image, 24, 0, $start_x, $start_y, $white, './verdana.ttf', $temp840);

// ETC ETC

imagesavealpha($png_image, TRUE); 

  imagepng($png_image);
  imagedestroy($png_image);
?>

getstate bash script
(gets the temperature from domoticz instance1 given an idx)

#!/bin/bash
curl -s --connect-timeout 2 --max-time 5 "http://ip-domoticz1:8080/json.htm?type=devices&rid=$1" | egrep "Temp|Humid" | awk '{print $3 }' | cut -f1 -d\. | grep -v \" | tr -d "\n\r" | sed s/,/%\ /g | awk '{ print $2"° "$1 }'

new.sh script gets the age of the reading from
domoticz1 or domoticz1
Usage: ./new.sh <domoticz-last-numer-ip> <idx> <maxageinseconds>

#!/bin/bash
## server idx time
now=$(date +%s)
lastupdate=$(curl -s -i -H "Accept: application/json" "http://192.168.1.$1:8080/json.htm?type=devices&rid=$2" |  grep LastUpdate | cut -f4 -d\" )
#echo $lastupdate
seen=$(date -d "$lastupdate" +%s)
#echo $seen
#echo "$(( $now - $seen))"
difftime="$(( $now - $seen))"
if [ $difftime -gt $3 ] ; then
  echo "WARN : too old - $difftime seconds"
  exit 1
else
  echo "OK : $difftime seconds"
  exit 0

Garbage display

I wanted to know when trash is being collected. So i made a dual led thingy.

Version without lid .. just to test

When we lived in Utrecht, the website which mentions when, what is collected was easy .. like a API

We live in Hilversum now, so i had to write a scraper.

UPDATE : Script not working anymore. Site has been changed, and I’m not willing to run a headless browser (phantomjs) to scrape the info

See below my new solution

Update new solution

My home assistant has a hacs addon installed which does the heavy lifting for me.
Why not use this info?

I wrote about NR and HA here

Home Assistant/NodeRed update

So getting the info for NR to parse:

I only need to use the lightblue node bottom right!

It is the current state node, inject a timestamp every day to get new values.
Parse this and send using Mqtt to my Led display thingy

Arpscanner

Changed stuff in my arpscanner

I want to know whats on my network, and be informed when a alien device connects.
This also helps me gathering all devices and macaddresses for a cmdb.

I’ve got below in my crontab

5 * * * * root /usr/local/bin/arpscanner

And the script:

#!/bin/bash
# Using a scanner on a specific vlan/interface
arp-scan -l -g  -I p1p1.10 | grep ^10 | grep -vi packets > /var/log/arpscanner
cat /var/log/arpscanner | awk '{ print $2 }'| while read ; do
grep $REPLY /var/local/arpscanner.lst >/dev/null || echo $REPLY | mail -s arpscanner henri@henriaanstoot.nl
done

New and checked devices i put in the file mentioned above:
/var/local/arpscanner.lst

Mount Taranaki New Zealand

While traveling New Zealand we went to see Mt Taranaki

Mount Taranaki (Māori: Taranaki Maunga), also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand’s North Island. It is the second highest point in the North Island, after Mount Ruapehu.

I made this timelapse using a Nikon D750.

X-plane on linux

Starting x-plane can be a problem on Linux when screens are not properly detected. (Like order of screens or sizes)

Below is a three-screen start script for Linux.

 while [  $count -lt $numscreens ]; do
    sleep 1
    count=$( wmctrl -l | grep X-System | wc -l)
 done
fi
screencount=1
wmctrl -l | grep X-Syst |awk '{ print $1 }' | while read ; do
