We both got a smallpipe, so there are 2 chanters in the house.
I designed a 3D adaptor for two chanters, and 3D printed this.
Taping the bottom part of one of the chanters and a part of the other, gave me the possibillity to play harmony’s.
There are only a few tunes which are suitable for playing like this.

I used OpenCV to track my face, and draw something that moves with me when i move.
Just a prove of concept. I will post used code when i find it back.
I’ve used a esp32 with 18650 battery holder.
I still have to 3d print a case 🙂

Bought a laser engraving kit, which can be mounted on my 3D Creality Printer, using magnets.
I’ve connected the power to a fan connector in 3D printer. So it can be controlled with gcode’s
M18 Z; stop Z axes, use only X and YM106 ; laser on commandM107 ; laser stop command
I’ve created a bash script which outlines our design with minimal and maximal x and y coordinates, so you can allign your object just in the right place.
It uses a low voltage on you laser, so its visible but it doesn’t burn you object.

UPDATE: 7 Jan 2023 – Another repair
15 Feb of this year my Concertina was deliverd on my doorstep.
It is a Wren 2 Anglo C/G Concertina by McNeela. A affordable good instrument.
Features
The word concertina refers to a family of hand-held bellows-driven free reed instruments constructed according to various systems, which differ in terms of keyboard layout, and whether individual buttons (keys) produce the same (unisonoric) or different (bisonoric) notes with changes in the direction of air pressure.
It is weird playing two notes with the same button, but i gives you a broader tonal range. Some notes are double, one on the pull action and one on the push action. When playing for a while it is possible to switch between those two to be able to play faster.
Because you can use the same pull or push as you already where playing, or the button is close by the one you already play.
So i had a little problem with the pull motion of the right hand A’ B’.
I didn’t want to send my Concertina back (Still has garantee, i know)
But sending it back to Ireland will take a while and has postal costs.
(I’ve fixed my Accordeon also, so why not try to fix it myself?)
(… aaand i was curious of the insides )
I had to look at the inner workings for a minute, and finding the right reed.
The middle picture above shows a white plastic strip, one of them was stuck. Moving it a little and carefully bending it, got it free and moveable again.
On with the lessons from Caitlin Nic Gabhann again!
https://www.youtube.com/watch?v=Z3tPzc6kKM0
2023 Repair:
One of the reeds fell off! It was not glued properly. A 5 minute fix!
Control a dimmer using a hex wireless box.
Parts
Put the box flat on the table to switch off.
When you put it on one side, it will controll your lights brightness.
20,40,60,80 and 100%, just by rotating and putting it down on its sides.

]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.
