First, we need to set the environment: 1. Installing Yotta and '''srecord''' (this is needed to create .hex)

sudo apt install yotta srecord
  1. Clone example git clone https://github.com/lancaster-university/microbit-samples cd microbit-samples
  2. Setup the target for building yotta target bbc-microbit-classic-gcc-nosd@https://github.com/lancaster-university/yotta-target-bbc-microbit-classic-gcc
  3. Build example yotta build 5.Copy .hex to Microbit folder cp ./build/bbc-microbit-classic-gcc/source/microbit-samples-combined.hex /media/"user"/MICROBIT

How to find the center of a circle

Install rclone

sudo -v ; curl https://rclone.org/install.sh | sudo bash This is needed because Debian 12 install rclone too old, without ProtonDrive support

Configure rclone

rclone config Chose ProtonDrive and add user and password

Install restic

sudo apt install restic

Inizialize restic repository

restic init -r rclone:[nameof remote rclone]:[dir in ProtonDrive]

Backup a folder

restic -r rclone:[nameof remote rclone]:[dir in ProtonDrive] backup [dir to backup] --compression auto --verbose --exclude-file=[file name] Where: * [nameof remote rclone] –> name of remote set in during rclone config * [dir in ProtonDrive] –> directory in ProtonDrive where to save the backup * [file name] –> a text filename with in the list of dir and files to exclude from backup

As a password vault

Initialize vault

pass init "Password Storage Key" Where “Password Storage Key” is the ID of the GPG key

Add a new password

pass insert

List the password tree

pass

Get a password

pass label Where label is the label of the password needed

Here are the dimensions from the original drawing: Meccano Rod Here the Openscad code:

module MeccanoRod(size){
    si=25.4;
    extradius=9/32*si;
    holeradius=2.1844;
    thick=0.9;
    difference(){
        cube([12.7,2*5.953125+12.7*(size-1),thick]);
        translate([12.7/2,12.7/2,0]) {
            for ( i = [1:1:size]) {
                translate([0,(i-1)*12.7, 0]) cylinder(thick,holeradius,holeradius);
            }
        }
        translate([12.7/2,12.7/2+holeradius,0]) difference() {
            cylinder(thick,2*extradius,2*extradius);
            cylinder(thick,extradius,extradius);
            translate([-20,0,0]) cube([40,40,thick]);
        }
       translate([12.7/2,12.7*(size)-12.7/2-holeradius,0]) difference() {
            cylinder(thick,2*extradius,2*extradius);
            cylinder(thick,extradius,extradius);
            translate([-20,-40,0]) cube([40,40,thick]);
