Happy Birthday Gentoo Linux

Oct 16, 2009

Gentoo became 10 years old on the 4th of October. Happy Birthday!!! This means that I have tried Gentoo about 10 years ago... what a long time. I am steady lucky with this distribution and I hope I will be it in the future. Thank you to all developers who had contributed to the Gentoo project in the past 10 years! You're have done a great work!

I love the Zsh prompt used in Gentoo! Here it is...

Sep 16, 2009

Since I am using the Zsh as default Shell on my Linux machines but not all of them are Gentoo based, I put the Gentoo prompt here.

Screenshot:

Just put the following lines to your .zshrc and you will be able to use this prompt on all distributions, not only Gentoo. Shure, I could copy the prompt file to the default directory in /usr/share/zsh/... but it is easier to just copy the .zshrc file from system to system...:

prompt_gentoo_setup () { prompt_gentoo_prompt=${1:-'blue'} prompt_gentoo_user=${2:-'green'} prompt_gentoo_root=${3:-'red'}  if [ "$USER" = 'root' ] then base_prompt="%B%F{$prompt_gentoo_root}%m%k " else base_prompt="%B%F{$prompt_gentoo_user}%n@%m%k " fi post_prompt="%b%f%k"  #setopt noxtrace localoptions  path_prompt="%B%F{$prompt_gentoo_prompt}%1~" PS1="$base_prompt$path_prompt %# $post_prompt" PS2="$base_prompt$path_prompt %_> $post_prompt" PS3="$base_prompt$path_prompt ?# $post_prompt" }  prompt_gentoo_setup "$@"

Arduino Relays

Mar 7, 2009

Yesterday evening I have build a small relays for switching high voltage lines with my Arduino. It uses the "Blink" example and switches on for 10 seconds then switches off for 10 seconds. I have used this document to get my work done.

Relays switched off.

Relays switched on.

Arduino TSL230R

Mar 3, 2009 - Updated: Dec 25, 2022

The next device is ready... ;) It is the TSL230R light sensor.

It prints out the Lux value every N seconds.

My code is based on this Blog post. You could buy the sensor at Sparkfun where you will find the Datasheet too. Another place for code is here. There is provided a modified version of the link above.
