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.

Arduino DS1621

Mar 1, 2009

Jehhaaaa... It is done!

My first Arduino device is born. Thanks to John! He learned me how to develop the driver for it. It is a DS1621 temperature sensor with 2-Wire (I²C) interface bus. And, YES! I have currently 17.5 degrees in my room.

I am impressed! The code will follow ASAP!
