Welding gloves laser logo

2025-03-25 fash Leave a comment

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 🙂

Making a plotter from a Laser Cutter

2025-02-14 fash Leave a comment

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!

Bash-completion, C64 Pico Amplifier and Laser cutting

2024-08-07 fash Leave a comment

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
}

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)

QuickPath and laser cut designs

2024-08-06 fash Leave a comment

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:

qp – lists config items with number and short key
qp 1 or qp c64demo – changes directory to below example
qp add c64demo /data/store/git/projects/c64code2024 – add a entry
qp del 1 – removes entry
qp mc tmp c64demo – starts midnight commander with left and right directories

Tomorrow some laser cutting, so let’s design some things to cut.

Jigsaw test – using engraving and cutting
Make a front for my bus manipulator
Make some cases for the game controllers (These are beta, and will be 3D printed at a later stage. My old 3D printer is slow)

Today some lasercutting for Home Assistant Spotify RFID

2024-03-08 fash Leave a comment

see:

Revisiting the Spotify Cube

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.

Wooden case with RFID reader being powered by external powerbank

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?

3D printed like this? https://makerworld.com/en/models/66671

UPDATE: 20240327 – Little Record I 3D printed with little groves.

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.
