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.

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.

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);
}

POC
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.
In 2012 I started with 3D printing, I didn’t have my own yet. So it was done using shapeways.
April 2019 I ordered my own, a Creality CR-10S.
Specs
Problem with this 3D Printer is the lack of a thermal runaway detection. My solution is a MQTT/Nodered warning system which plays an alarm and uses a shelly to disconnect the power.

I’m using a filament sensor like the one in below picture
It used to be a DIY thingy using an arduino. (below)
Filament under my table ( in the “dark” )
Software on my mobile
Hints and tips
Want to know what filament is in your gcode?

UPDATE 20230803
Best gap filler i found which is easily sanded down with a dremel.
Alabastine Polyester Plamuur
I wanted to know when trash is being collected. So i made a dual led thingy.
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
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
UPDATE: 20230320 new version
My first version of the Bluetooth page turner.
This was made using an Arduino and some buttons.
I’m using Fbreader and Ebookdroid on the tablet.
Code:
Note: Volume buttons work for both apps, if you want to use other keys, you need to put a keymap.xml file in your fbreader books directory on your android device to remap those!
#include <BleKeyboard.h>
#define RIGHT_TURN 4
#define LEFT_TURN 5
BleKeyboard bleKeyboard("fashpageturner", "Bluetooth Device Manufacturer", 100);
void setup() {
bleKeyboard.begin();
pinMode(LEFT_TURN, INPUT_PULLUP);
pinMode(RIGHT_TURN, INPUT_PULLUP);
}
void loop() {
if (bleKeyboard.isConnected() && !digitalRead(RIGHT_TURN)) {
bleKeyboard.press(KEY_MEDIA_VOLUME_UP);
delay (100);
bleKeyboard.releaseAll();
}
if (bleKeyboard.isConnected() && !digitalRead(LEFT_TURN)) {
bleKeyboard.press(KEY_MEDIA_VOLUME_DOWN);
delay (100);
bleKeyboard.releaseAll();
}
}
