UPDATE 20231020 – Via USB Serial (also schematic for below integration)
https://www.henriaanstoot.nl/2023/10/20/thunderbird-mail-notification-flag-via-usb/
Using a servo which is MQTT controlled, and a slash command in Mattermost, i can be notified by friends and colleages.
Flag, and monitor-stand are 3D printed.
ESP is a simple wemos mini.
Coline sometimes plays games with her sisters online using my streaming server. (Due to Covid)
Some games are difficult because you have to point to a location on the table. So i came up with a laser pointer solution.
The idea is: Send a url to the players with a streaming camera, you see the game on your screen but you can click on a location on the screen to move a laser pointer to that location.
Below is a proof of concept using the Lasercut worldmap on the wall and a website with a worldmap.
Code to place on the ESP:
This will connect to the MQTT broker and listens for messages on the servo/pan and tilt topic.
#include <ESP8266WiFi.h>
#include <PubSubClient.h>
#include <Servo.h>
Servo pan;
Servo tilt;
const char* ssid = "MYSSI";
const char* password = "MYWIFIPASS";
const char* mqtt_server = "IPMQTTBROKER";
const char* topic_pan = "servo/pan";
const char* topic_tilt = "servo/tilt";
WiFiClient espClient;
PubSubClient client(espClient);
long lastMsg = 0;
char msg[50];
int value = 0;
void setup() {
pan.attach(D5);
tilt.attach(D6);
setup_wifi();
client.setServer(mqtt_server, 1883);
client.setCallback(callback);
}
void setup_wifi() {
delay(5);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
}
}
void callback(char* topic, byte* payload, unsigned int length) {
String string;
for (int i = 0; i < length; i++) {
string+=((char)payload[i]);
}
int pos = string.toInt();
if ( strcmp(topic, topic_pan) == 0 ) {
pan.write(pos);
}
if ( strcmp(topic, topic_tilt) == 0 ) {
tilt.write(pos);
}
delay(15);
}
void reconnect() {
while (!client.connected()) {
if (client.connect("ESP8266Client")) {
client.subscribe(topic_pan);
client.subscribe(topic_tilt);
} else {
delay(5000);
}
}
}
void loop() {
if (!client.connected()) {
reconnect();
}
client.loop();
delay(100);
}
Website PHP code:
This has some calibration code to get coordinates lined-up
<?Php
$foo_x=$_POST['foo_x'];
$foo_y=$_POST['foo_y'];
echo "X=$foo_x, Y=$foo_y ";
$x=160 - round($foo_x/30);
$y=38 - round($foo_y/100);
system('/usr/bin/mosquitto_pub -h 10.1.0.17 -t servo/pan -m "' . $x . '"');
system('/usr/bin/mosquitto_pub -h 10.1.0.17 -t servo/tilt -m "' . $y . '"');
?>
<form action='' method=post>
<input type="image" alt=' Finding coordinates of an image' src="worldmap.jpg"
name="foo" style=cursor:crosshair;/>
</form>
POC
Remove the screen and check its connector.
Maybe you can buy a controller board in china for cheap.
I took apart a EEEpc with a nice little screen.
I looked for HSD100IFW1-A00 1024-600 controller.
And ordered a
Driver Board for 10.1 “HSD100IFW1-A00/HSD100IFW1-A04 / HSD100IFW1 Lcd Composite + Tv(RF) + Usb + Vga + Hdmi-Compatibel 1024 × 600 Controller Board
It was only around 20 euro’s.
We are movieholic’s. Watching everything. Sometimes we thing “why the F did we watch that” other times it’s a pretty unknown jewel.
We loved “De kijk van Koolhoven” a dutch tv serie about movies, by our dutch director Martin van Koolhoven.
He explained why he liked certain movies. Tarantino did simular but couldn’t find much about that
We started watching the top 250 IMDB movies a few years ago. Comming a long way, and has been a treat.
Below a list of top movies i could thing of in serveral genre’s.
Nowhere complete, and probably forgot better ones
Action
Animation
Comedy
Crime
Drama
Dutch
Fantasy
Film Noir
Horror
IT-Related
Mindfuck
Pre-1940
SciFy
Fun to watch
War
Weird
Western
Woman Power
List for Maryse
Indian movies
Generated a world map where we’ve been … biggest red part .. seen the least of it 🙂
Vacation or work

UPDATE: 20220307
I’m using Kodi for a long time now, but never was really satisfied with the results of automatically scraping metadata.
Movie names had to be just right, and changing some metadata was hard.
A while ago i made a NFO generator for own movies, digitized 8mm material, mobile movies etc.
So for movies/tv shows i started using Tinymediamanager for metadata management. You have more controll over your NFO files.
Don’t forget to add media sources to Kodi, selecting the ‘local NFO scraper’ option.
I’m using TVDB scraper in TMM, and trakt to mark seen.
But that way i’m missing IMDB top 250.
Fix:
UPDATE:
Problems with premiered date/release date showing up as movie date in kodi? Here is my fix.
find . -type f -name '*.nfo' -print -exec sed -i -e '/<premiered>/d' {} \;
Today newest addition Concertina

I don’t like cloud enabled devices, except if it is my own cloud!
I bought a Hikvision doorcam, when i researched the diverse doorcams where was a hikvision which could use a existing doorchime.
When i got mine in, it did not have this feature.
Damn what to do!
Where where several solutions i could think off:
I looked at the electronics and tried to find out how things where connected and where things where you could make use of.
I soldered some wires to a little print where the pushbutton was located.
Now i could read the button press, video was easily captured by using a RTSP port.
Does it work? … yes, but i’m not happy about it
Video playback in Zoneminder or VLC

A solution i used before for a generic doorbell
Just read the gpio pin with Arduino or raspberry.
A generic optocoupler will work, just check your resistor.
2019-06-08 I’ve bought myself Uboot the game.
It is one of my favourite board games.
Playing with a cardboard uboot is … okay. But when you have a 3D printer .. do i need to say more?
3D printed version assembled and completed in Jan 2021
Led’s are controlled by a Arduino, Mqtt or a fysical button can be used.
