CRImier / mcp28003.ino
Created May 13, 2015 23:03
This Arduino script is used to communicate to HD44780 LCD attached to WIDE.HK small I2C LCD backpack using MCP23008 IO expander. It's been taken from http://playground.arduino.cc/Code/I2CPortExpanderAndLCDs , seemingly modified by WIDE.HK and then finished by me. I had to concatenate it all in one script (stupid Arduino IDE cannot find .h files …
#include <Wire.h>
class LCDI2C4Bit {
public:
LCDI2C4Bit(int devI2CAddress, int num_lines, int lcdwidth);
void commandWrite(int command);
void init();
void print(int value);
void printIn(char value[]);
void clear();

CRImier / pybssort.py
Last active December 27, 2015 13:09
This Python program is used to manage scanning directories while batch-scanning so that all the files get automatically sorted. Its main objective is to provide path to current chosen directory when called like "pybssort dir" and let users choose, create and manage directories using "pybssort [list|add|del|set]". It requires python-webpy solely …

BASEPATH = "/home/user/Scans"
DIR = "/var/lib/pybssort/"
DB_NAME = os.path.join(DIR, "pybssort.db")

CRImier / firewall
Created March 23, 2014 01:36
This is a Bash script (wrapper around iptables) that creates a simple firewall from one interface to another. It is designed for portable servers that might be getting Internet internet from 3G/wireless/wired connection and, therefore, uplink interface changes, but local does not, so local interface name is hard-coded. It is invoked like "firewa…

CRImier / export.py
Last active October 26, 2021 01:15
This script is for exporting your playlist items to a single folder. Save, change two variables to suit your needs and run =) One use case is: you have a music collection and a playlist containing the best songs of this collection, and you want to load only the best songs to your MP3 player with limited space. This also doesn't overwrite files, …
import os
import shutil
directory_name = "playlist/"
playlist_name = "playlist.m3u"
f = open(playlist_name, "r")
files = []
for line in f:
line = line.strip().strip("\n").strip("\r")
