casregister.blogg.se - Raspberry pi zero w camera setup

I made a directory called camera in home/pi I wrote a shell script to take pictures using raspistill. I built a little stand for it out of Lego and set up the plant maze.

Now the Pi was ready to start taking images. Instructions for how to do these things are just one google search away.

I needed to set up SMB sharing on the new Pi.

I needed to give this one its own identity to prevent network conflicts.

Since I have several Raspberry Pis on the LAN.

I enabled ssh and camera port in Raspberry Pi Configuration, disabled bluetooth and set the correct timezone (this can probably be done in PiBaker but I forgot).

After this I could log in and use the Pi Zero remotely.Ī few more minor steps were needed for full functionality: I needed to connect to a monitor to rectify this by changing to VNC password in the VNC GUI. Well in theory! It turns out that VNC via Mac does not work with the UNIX style password which is the default on the Pi. That meant I could plug it in and start using it headless. I used PiBaker to format the SD Card, load on Raspbian and add a startup script that would connect the Pi Zero to WiFi and enable VNC. Another option is to use a smaller card and get the Pi to save the images to a server.

Power supplies and SD cards are readily available. I put together the PiCam with a fresh Raspbian full image on a 16GB SD card. Pi Zero with camera module (without IR filter) and a case are available for around £40. Other units are shooting scenery and the autofocus on the unit is great. The camera didn’t focus well on the maze which was a bit too close. I downsampled the images to make the video. The Pi took pictures every 5 min, but I sampled at 10 min in order to make the movie (after discarding the pictures after the sun went down). After a delay, you can see four beans sprouting and then one eventually makes it to the top of the maze.
