I want to take simple ABC Music notation tunes and convert these to animations which shows you which keys to press and to push or pull.
This is a work in progress.
Script is using ImageMagick and ffmpeg
I started this in bash, and i should rewrite this in python.
Bash script which generates the images

A world map generator in php.
This php script selects randomly 3 cities from a CSV file and draws these on a worldmap.
No cities wil be choosen which have could cause a drawing overlap.
Every player can see the same generated worldmap with a countdown timer.

Used world image to draw on.
The squares and city names are dynamically drawn using php GD lib.
apt-get install apache2 php php-gd
php example:
// create image from source
$src = imagecreatefromjpeg('world.jpg');
$dest = imagecreatetruecolor(1920, 1080);
// 1920x1080
imagecopy($dest, $src, 0, 0, 0,0, 1920, 1080);
// assign color
$white = imagecolorallocate($dest, 255, 255, 255);
// rectangle example
imagerectangle($dest, $x, $y, $x2, $y2, $white);
// add text
Imagettftext($dest, 24, 0, $x, $y, $white, $font, "Text");
// set header output as image
header('Content-Type: image/jpg');
// output to browser
imagejpeg($dest);
// output to file
imagejpeg($dest, 'generatedworld.jpg');
// Free memory
imagedestroy($dest);
imagedestroy($src);
world.php is included as image, it dynamically generates the map

A nice book for ideas
Work document for friends
In the past i’ve converted some VHS movies speech to text, using all kinds of tools.
Lets use some opensource tools!
pip install moviepy pip install SpeechRecognition
Create a python script with the following:
(Called mine wav2txt.py)
import math, contextlib
import speech_recognition as sr
from moviepy.editor import AudioFileClip
movie_audio_file_name = "movieadiofile.wav"
with contextlib.closing(wave.open(movie_audio_file_name,'r')) as f:
frames = f.getnframes()
rate = f.getframerate()
duration = frames / float(rate)
total_duration = math.ceil(duration / 60)
r = sr.Recognizer()
for i in range(0, total_duration):
with sr.AudioFile(movie_audio_file_name) as source:
audio = r.record(source, offset=i*60, duration=60)
f = open("transcription.txt", "a")
f.write(r.recognize_google(audio, language="nl-NL"))
f.write(" ")
f.close()
Now convert a movie to wav using below.
ffmpeg -i /fileserver/path/koolhoven.mkv movieaudiofile.wav
run python3 wav2txt.py
output
(Note .. these are not timestamped for subtitles)
I only needed the things being said in the home movie recordings as text.
Ik zit hier in de film The James Dean aan de

These tiny modules use a Clock and Data signal.
The rest of the pins are for 3.3V and Gnd.
There are many libraries you can choose from, i’ve tried several.
For now, i ended up with this one.
Another promising one is https://github.com/AKJ7/TM1637

Now i have to add Wifi and Mqtt so it can remotely controlled.

// Once connected, publish an announcement...
client.publish("escape/seg1ping", "seg1alive");
// ... and resubscribe
client.subscribe("escape/seg1data");
} else {
Serial.print("failed, rc=");
Serial.print(client.state());
Serial.println(" try again in 5 seconds");
// Wait 5 seconds before retrying
delay(5000);
}
}
}
void loop() {

}
client.loop();
unsigned long now = millis();
if (now - lastMsg > 2000) {
lastMsg = now;
++value;
snprintf (msg, MSG_BUFFER_SIZE, "seg1alive #%ld", value);
Serial.print("Publish message: ");
Serial.println(msg);
client.publish("escape/seg1ping", msg);
}
}
As part of my internet based escape room.
I took the idea from the Keep-talking-and-nobody-explodes game.
When starting up, is gets the configuration from a Mqtt Topic.
So i can create a different setup over the internet.
The result is also send back via MQTT.
(example play, all players are on different locations)
I used a wire with a line. Multiple colors for jacks and sockets.
It’s also possible to connect a jack to a jack.
Loads of possibilities.
Todo:
Wifi and Mqtt part
Debounce software or hardware
In post below i posted the score for Bella Ciao
