ChatGPT IA generated chats/texts

2023-01-02 fash Leave a comment

ChatGPT is a large language model chatbot developed by OpenAI based on GPT-3.5. It has a remarkable ability to interact in conversational dialogue form and provide responses that can appear surprisingly human.

So i asked stuff like:

Thats a pretty good joke about a 6502 CPU. I tought it would be a hard question

The question : “what are women looking for in a man”
Gave a lot of lines :
No generic answer
Lines with Respect, Humor, Kindness, Confidence

Then it stopped with:

Typical .. even AI is baffled by women.

Below a chat session from a great friend of mine Tyrone

Tyrone: Ok could you write me a commodore c64 assembly routine to make the screen white?

Certainly! Here is a simple assembly routine that will clear the screen and set all of the pixels to white on a Commodore 64:

Copy code

ldx #$00
ldy #$00
clear_screen:
sta $d800,x
inx
cpx #$40
bne clear_screen

This code will loop through all of the screen memory locations and set the value at each location to $00, which will turn all of the pixels white. The inx and iny instructions are used to increment the X and Y registers, which are used to keep track of the current screen position. The cpy instruction is used to compare the value in the Y register to $20, and the bne instruction is used to branch back to the clear_screen label if the values are not equal, causing the loop to continue until the entire screen has been cleared.

I hope this helps! Let me know if you have any questions.

Tyrone: Well a big code but i wanted to make the screen the color white not with a character space .. this is also white but it's more logical that the color is named then the white space this code should be three lines of could can you do this?

Certainly! Here is a simple assembly routine that will clear the screen and set all of the pixels to white on a Commodore 64:

Copy code

ldx #$00
ldy #$00
clear_screen:
sta $d800,x
inx
cpx #$40
bne clear_screen

This code will loop through all of the screen memory locations and set the value at each location to $ff, which will turn all of the pixels white. The inx instruction is used to increment the X register, which is used to keep track of the current screen position. The cpx instruction is used to compare the value in the X register to $40, and the bne instruction is used to branch back to the clear_screen label if the values are not equal, causing the loop to continue until the entire screen has been cleared.

I hope this helps! Let me know if you have any questions.

Tyrone: This is wrong here is a hint use registers d020 and d021 for screen and border color

I apologize for the mistake in my previous response. Here is the corrected code that will set the screen and border colors to white on a Commodore 64:

Copy code

lda #$0f
sta $d020
sta $d021

This code will store the value $0f in the memory locations at $d020 and $d021, which are the registers that control the screen and border colors on the Commodore 64. The value $0f corresponds to the color white.

I hope this helps! Let me know if you have any questions.

Thank you ai

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.

CSV example with places and coordinates (cities.csv)

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

<?php

putenv('GDFONTPATH=' . realpath('.'));

// Name the font to be used (note the lack of the .ttf extension)
$font = 'tahoma.ttf';
$city1="";
$city2="";
$city3="";

// Create image instances
$src = imagecreatefromjpeg('world.jpg');
$dest = imagecreatetruecolor(1920, 1080);

// Copy
imagecopy($dest, $src, 0, 0, 0,0, 1920, 1080);

$green = imagecolorallocate($dest, 255, 255, 255);

Movie to txt in dutch

2022-12-22 fash Leave a comment

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
wereld voorstelde en daarmee de tienerfilm ingeleverd introduceren zelden werden onrustige 10 asiel zo mooi blootgelegd als ik deze film van Nicolas bij en dat wordt dan meteen toevallig even de mooiste
titels ooit wel eens autocross vanavond kijken we naar de kom ik nog even veel zomer dat je voor het eerste meisje Zoem de eerste baantje

Connect the wires puzzle

2022-12-20 fash Leave a comment

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)

Player 1 figures out the wires.
Player 2 connects the wires.
Player 3 sees the result (correct or not) and next puzzle opens up for Player 3

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

Serial link between MSDos and Linux troubles

2022-12-14 fash Leave a comment

In post https://www.henriaanstoot.nl/2022/11/25/disk-troubles-or-missing-old-skool-hardware/ i mentioned the serial connectors i’ve bought to connect the Laser XT to my Workstation to transfer files.

The null modem i’ve made is like mentioned on https://en.wikipedia.org/wiki/Null_modem

I’ve used the loopback handshaking using 3 wires. ( Only using a DB25 and a DB9 on the other end )

So i configured the Linux side as follows.

I’ve tried two usb to serial converters.

Both when trying on windows 10 are not supported any more

Dec 14 17:34:40 zspot kernel: [ 1082.299607] usb 1-4: pl2303 converter now attached to ttyUSB0

sudo stty -F /dev/ttyUSB0 9600

Then i start dosbox.
To enable a com port i have to enter:

serial1=directserial realport:ttyUSB0

Starting Norton Commander and selecting COM1

After a few seconds i got this ..

What else is there to check?
At least i’ve still got the Flux Engine!

Magic Mirror no more .. lets reuse the display

2022-12-09 fash Leave a comment

I never look in the mirror, so why do i need one?
The mirror foil was already ugly in the corners.
There were bumps.
Never finished a proper interface

This one was made using a touch screen, so there are always fingerprints you could see

I’m going to use the display for an in-house small Escape Room idea i have.

Only the time part still worked, but i could not find the right cables for the touch part. The buttons displayed are meaningless anyway 🙂
Just a mockup

Mirror part was done using a Safety/One way mirror foil.
Cut a part as large as you screen, spray a little water and stick it on.

At some point i displayed Dashticz on there.
Apparently i started playing with a magic mirror setup in 2015, according some timestamps of code on my fileserver.

Migrating some old Sonoff S20 smart plugs

2022-12-07 fash Leave a comment

(From ESPEASY to ESPHOME without soldering)

I previously had these smartplugs flashed with EspEasy (I hate cloud enabled devices)
I will post something about flashing these and others.
Maybe … because you can find a lot of information on the internet.
But i’ve used several tools, and made tools for this process.
( Raspberry Zero mobile tool and 3D printed PCB holder for example)

Well ..

I was using these devices in our previous home using curl commands and on a main wifi network.
So i have to change the SSID and migrate from Espeasy to ESPhome so i can use these devices with Home Assistant.

Step 1 : Start in Access Point mode and migrate to my current Wifi Iot network.

Using my phone i made the necessary changes.

Goto HomeAssistant and ESPhome (you need to install this first via HACS)
Press the green + Add device and give it a name

Next select the device type (Sonoff S20 in this case)

Press install and select manual download

Above will compile a binary for the Sonoff device.

Go back to your Sonoff interface and go to the tools tab.
We can reflash the device without connecting this with wires to our computer.

Press Firmware load and select your downloaded binary

Back in HA it should say “online”

Pressing edit gives us a config page. Nothing works .. yet
We need to add some yaml entries.
( use https://esphome.io/devices/sonoff_s20.html )
