# pi-timelapse

## Config pi

- enable camera

- enable serial (optional)

- enable gpio

- extend file system (optional)

## Install dependencies

    sudo apt install libudev-dev 

## Hardware interface

Timelapse JPG capture with raspberry pi and Raspberry Pi camera

Hardware/Schematic: https://easyeda.com/zebrajaeger/pi-timelapse

TODO: shutdown: https://www.embeddedcomputing.com/technology/open-source/development-kits/raspberry-pi-power-up-and-shutdown-with-a-physical-button

## Install requirements

### Update

    sudo apt update

    sudo apt upgrade

### NodeJs

- nvm does not work for development, node has to be installed globally

    sudo curl -sL https://deb.nodesource.com/setup_14.x | sudo bash -

    sudo apt-get install -y nodejs

check:

    pi@pi4:~ $ node --version

    v14.17.2

    pi@pi4:~ $ which node

    /usr/bin/node

### nodemon (develop only)

    sudo npm i -g nodemon

### Yarn (develop, optional)

    sudo npm i yarn

### usbmount

- usbmount, take a look at https://gist.github.com/zebrajaeger/168341df88abb6caaea5a029a2117925

- nodejs 

### create 200MB temp dir (RAMdrive)

#### Create folder

    sudo mkdir /var/cam

    sudo chmod 1757 /var/cam

#### create fstab entry

    sudo nano /etc/fstab

add

    tmpfs /var/cam tmpfs nodev,nosuid,size=200M 0 0

    

mount it for this time (automatically on reboot)

    sudo mount -a

check it

    pi@pi4:~ $ mount | grep cam

    tmpfs on /var/cam type tmpfs (rw,nosuid,nodev,relatime,size=204800k)

## Installation

### Get code

    cd ~

    git clone https://github.com/zebrajaeger/pi-timelapse.git

### Autostart

    crontab -e

add

    @reboot npm --prefix /home/pi/pi-timelapse/src run start

## Pitfalls

### File system of the external USB-Drive

Never ever use ntfs formatted usb-hdds with this software. 

The write-performance is in my case < 2Mb/s and way to slow.

The same HDD, formatted in ext4 works very well. 

## Develop

Uses rsync and seems to have trouble with cygwin. 

    cd dev

    npm run develop

## Better using eth instead of wifi (unstable)

Configure 

- wifi with dhcp 

- eth0 with dhcp and a static ip as fallback (direct connection to developer pc)

    sudo nano /etc/dhcpcd.conf

add

    profile static_eth0

    static ip_address=10.1.2.55/24

    interface eth0

    fallback static_eth0

the reboot
