* this Tutorial explains how to setup a RasPi Zero W, which already has an integrated wifi module. For other models you have to setup wifi yourself.

Follow this tutorial: https://www.novaspirit.com/2018/01/09/tiny-core-raspberry-pi-zero-w-install/

There's also a video that covers the tutorial: https://www.youtube.com/watch?v=aKvW59uk4PY

Now you are ready to start the RasPi. All further steps assume that you access the RasPi via ssh. The standard user is tc (password piCore), the standard hostname is box.

$ ssh tc@box

TinyCore ships with vi. There's also a version of nano for TinyCore which can be installed from the app repository.

$ tce-load -wi nano.tcz

To get TreeCam running, you need lftp.

$ tce-load -wi lftp.tcz

You might also want to install rsync to copy files directly between the RasPi and your computer. This is not needed for TreeCam but makes setup easier.

$ tce-load -wi rsync.tcz

You also need rsync to be installed on your computer, which already is the case in many distributions.

This step is optional but giving the RasPi a catchy hostname makes it easier to find it in the network. The hostname is defined in two locations.

Fist location is /etc/hosts.

$ sudo nano /etc/hosts

Replace box by your favorite hostname. I will use treecam in this tutorial.

The second location is /etc/hostname which contains nothing but the hostname.

$ sudo nano /etc/hostname

Replace box by the same hostname you used in the previous step.

Reboot the RasPi and check if you can now ssh into it with the new hostname.

Install the app rpi-vc (videocore) to get the camera running.

$ tce-load -wi rpi-vc.tcz

Set access rights for the video device. To have them set at every boot, add the following line to /opt/bootlocal.sh.

chmod 777 /dev/vchiq

Reboot and check if you can take a picture with raspistill.

$ cd ~
$ raspistill -o pic.jpg

To check the result, you can copy it to your computer with rsync. Run the following command on your computer.

$ cd ~
$ rsync tc@treecam:/home/tc/pic.jpg .

To enable the cron service at startup, add the following line to /opt/bootlocal.sh

cron -L /dev/null 2>&1

You also need to add the cron bootflag to the boot command in
