Making Chiptune Music using Sonic Pi v2.0

Warning: this might not work on a RaspberryPi yet

I was curious about making retro gaming sounds using Sonic Pi. A couple of months and a lot of Googling later, here's the original Mario Bros theme as it was heard on the NES console.

I'm (just about) old enough to remember rushing home from school to play this game at Philip Boucher's house, sitting cross-legged in front of the TV till my feet got pins and needles. Working out how to recreate it for Sonic Pi was a lot of fun!

MQTT Generator

A simple python 3 script to generate sensor data from a config file and send it to an MQTT broker.

Usage

Download mqttgen.py and config.json files (click on the Raw button at the top right and then save the content), edit config.json to fit your needs, if you are using it to run the Event Fabric sensors dashboard then don't change the topic in config.json unless you want to change it in the dashboard too.

Pocket Chip Debian 10 Upgrade Guide

The purpose of this tutorial is to walk through the required steps to upgrade NXT chip (or pocketchip) from debian jessie to debian buster.

If you would like to start your Chip from scratch, follow the steps in the Preparation section.

Preparation (Optional)

A linux host machine, recommended Ubuntu 18.04. However I managed to do it with 20.10 with some tweak.

Remove unused packages on Raspberry Pi

(this is worth looking at http://www.stefan-seelmann.de/wiki/rasperrypi-homeserver, which is basically this:

apt-get purge --auto-remove scratch debian-reference-en dillo idle3 python3-tk idle python-pygame python-tk lightdm gnome-themes-standard gnome-icon-theme raspberrypi-artwork gvfs-backends gvfs-fuse desktop-base lxpolkit netsurf-gtk zenity xdg-utils mupdf gtk2-engines alsa-utils  lxde lxtask menu-xdg gksu midori xserver-xorg xinit xserver-xorg-video-fbdev libraspberrypi-dev libraspberrypi-doc dbus-x11 libx11-6 libx11-data libx11-xcb1 x11-common x11-utils lxde-icon-theme gconf-service gconf2-common

)

Warning: this will probably break something. If you need sound, don't remove the "alsa" packages

sudo apt-get --yes purge xserver-common x11-xfs-utils x11-xserver-utils xinit libsmbclient blt gvfs gvfs-backends gvfs-daemons gvfs-fuse idle idle-python2.7 idle-python3.2 idle3 libaudio2 libice6 liblightdm-gobject-1-0 libobrender27 libpulse0 libqt4-svg libqt
