I bought a lasercutter a few years ago. Time for a upgrade.
I moved from a 5.5Watt to a 20Watt version.
Also included an Air-assist! (Not in picture) Which helps a lot.
First serious thing .. a sign to put on my office pc for my girlfriend.
She turns my computer off, when it looks like its not doing anything.
Often Machine Learning things, bash scripts are running which can’t be paused or stopped.
Example with/without air assist.
(Didn´t cut in a single pass, and brown edges!)
I saw a movie clip of two guys playing TAK.
It looked interesting, so I DIY-ed something.
https://en.wikipedia.org/wiki/Tak_(game)
Laser engraved a cork plate.
Cut some wooden blocks into squares, and stained half of it.
Should I engrave something on the blocks?
A friend asked if it was possible to use my Laser cutter to “engrave” welding gloves.
I said, “Ehh dunno, but let’s try!”
So now my welding gloves have my business logo 🙂
I’ve got a SculpFun Laser Cutter.
I’m using this a lot … as lasercutter.
But you can also use a laser cutter as a Plotter or vinyl cutter!
Just remove the laser head, and replace it with a pen or knife!
(360 swivel blade)
First : replace laserhead and make a controllable pen holder.
My Laser Cutter can be controlled using G-codes real-time.
Example my etch a sketch.
Now I just have to add a Z axis controller to control pen up/down.
While I’m not afraid to cut things by hand. Like our front door decoration.
I like a more precise and repeatable way. I’ve cut lots of Nae Bother Logo’s like on my Laptop. (These were made using a computer cutter)
Test code (no gcode yet):
#include <Servo.h>
const int buttonPin = 16;
int lastButtonState = 0;
Servo myservo;
void setup() {
pinMode(buttonPin, INPUT);
myservo.attach(2);
myservo.write(0);
Serial.begin(115200);
}
void loop() {
int reading = digitalRead(buttonPin);
if (reading == 1 && lastButtonState == 0) {
myservo.write(0);
Serial.println("UP");
lastButtonState = 1;
}
if (reading == 0 && lastButtonState == 1) {
myservo.write(160);
Serial.println("DOWN");
lastButtonState = 0;
}
}
The puzzle was very hard. But I like a challenge!

Worked on bash autocompletion for QP
source below script to get
qp <tab><tab> shortcode
Not happy with both versions yet …
#/usr/bin/env bash
# Version 0.1
qpcompl()
{
COMPREPLY=($(compgen -W "$(qp | cut -f2 -d \' )" "${COMP_WORDS[1]}"))
}
complete -F qpcompl qp
--------------------------------------------------------------------------------------
# V 0.2
_qp_complete() {
local cur prev opts
COMPREPLY=()
cur="${COMP_WORDS[COMP_CWORD]}"
prev="${COMP_WORDS[COMP_CWORD-2]}"
opts="add del"
case "${prev}" in
add)
COMPREPLY=( $(compgen -d -- ${cur} ))
return 0
;;
del)
COMPREPLY=( $(compgen -f -- ${cur}) )
return 0
;;
*)
COMPREPLY=( $(compgen -W "$(echo add; echo del ;echo "" ; qp)" -- ${cur}) )
return 0
;;
esac
}
complete -F _qp_complete -o nospace qp

And a Jigsaw in progress (with our own made clock in the background)
C64 Pico Amplifier
My C64 had a problem with previous attached speaker.
It drew too much current to drive. And random characters where printed.
Choosing another speaker and a minimal amplifier solved the issue.
(Thanks to Bigred finding the problem at Bornhack 2024)

Today I made a Linux version of Tyrone’s QuickPath tool.
My friend Tyrone came up with a great idea.
A directory switching tool, to move around in often used directories.
You can use a keyword to move around. These keywords are configured in a config file.
Even starting Total Commander with preset directories.
Work/Private/Programming environments.
His version uses PowerShell, but he wanted a multiplatform version, so we have chosen to use Python on both environments.
My version uses Python and Bash.
(Bash is used for a change directory workaround on Linux and bash completion.)
Source will be in Tyrone’s git when finished.
Options:
Tomorrow some laser cutting, so let’s design some things to cut.
Slate of stone engraved using my Sculpfun S9 Engraver.
It will be placed next to our front door.

Lasercutting a case and the playlist selectors.
Close-up RFID stickers I’m using.
Below is a test with different methods.
I like reading the booklets, so a CD i cool, and I don’t need a CD player.
(The RFID tag is in the case)
The little cards are for bought audio files I don’t have a physical CD for.
What am I gonna do?
Cube as I had? Wooden playlist selectors as in above movies?
The cards I’ve printed?
Maybe a small record player with an RFID reader inside?

In the past, Aloha and I made a simple solution like this using barcodes in < 2000s.
Due to the many obscure recordings I have, I am thinking about creating something like this for Picore player and my local Squeezebox server.

My good friend Vincent wanted to have a stencil to mark property.
Open in inkscape and use trace bitmap.
Check the movie for settings. (Re-did the process using other text)
Saved as svg (vector), and used LightBurn to lasercut this into wood.
Below a cardboard preview.
