Raspberry pi Camera

1. Enable camera module using raspi-config via sudo raspi-config 2. Check the camera via vcgencmd get_camera 3. use raspistill to take photos/timelapse/video. Official docs: https://www.raspberrypi.org/documentation/raspbian/applications/camera.md

Example for timelapse that runs outside of active shell: raspistill -w 1280 -h 720 -n -q 10 -t 43200000 -tl 60000 -o cam%04d.jpg & disown Disown is useful as it will let the program/job continue to run but no longer requires a terminal to be active. This applies even to jobs started while you used SSH on your Raspberry Pi and and upon exiting SSH, the job will continue.

Magic Mirror Mini Guide

Mini guide to set up Magic Mirror on a Raspberry Pi 3

Execute the following command on your Raspberry Pi to install MagicMirror²: curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh | bash

If you want auto start into MagicMirror using pm2 then at the prompt press Y and then reboot with the following command: sudo reboot

If you DON’T want to auto start into MagicMirror using pm2 then at the prompt press n and then reboot with the following command: sudo reboot

then you have to manually start it EVERY TIME from the terminal by entering cd ~/MagicMirror and then the following command: npm start

If the MagicMIrror doesn’t start for you after rebooting or starting it from the terminal, then you will need to reinstall it. You’ll still need to sign up for an openweather appid, adjust font sizes, rotate the screen, and probably more customization for your particular screen. More info at the official github: https://github.com/MichMich/MagicMirror and https://forum.magicmirror.builders/

Before installing Manjaro

Before you start installing Manjaro Linux or any other OS, you must do some basic checks.

Check that the HP Pavilion dv6451us Notebook PC powers on while plugged in. It is safe to assume that the original Notebook battery will no longer be a sufficent power source for any amount of time as it is from 2007(making it 10 years old at the time of writing) By power on, I mean it loads past POST (power-on self-test) and into the OS that has been installed on it.

Check various components of the Notebook PC to make sure they are still in working order or you can live without them. Here is dcent list of things to check: keyboard, touchpad, cd drive, ethernet, wifi, bluetooth, audio, microphone, remote, multimedia hotkeys, and usb ports.

Optional but recommended - Disassemble your HP Notebook PC in order to clean out dust in the fan/heatsink and apply new thermal paste. Guide with pictures here: https://www.ifixit.com/Device/HP_Pavilion_dv6000

About

This blog is to document what is allowed and not allowed on a 2007 HP Pavilion dv6451us Notebook PC with Manjaro Linux. The original OS was Windows Vista. The decision was made to go with the Manjaro Linux [Gnome] after trying an Ubuntu LiveUSB and Manjaro LiveUSB. There was greater success using the Manjaro LiveUSB in terms of having various things work without adding additional packages or configuration.

Manjaro is a GNU/Linux distribution based on Arch Linux. Manjaro’s strong points are its user-friendly setup and  compatibility with the Arch User Repositories [AUR]. It’s seen as a good stepping stone for anyone interested in Arch Linux, but is uncertain of how to use Arch or is intimated by directly going into Arch.
