A four cameara raspberry stack system. It is supposed to create animated GIFs out of 4 simultaneously created pictures shot by 4 separate raspberry pi cameras.
- Get a raspberry image.
- Write it on a card
- install python, git TODO: collect pip dependencies
- check the code out
- generate an ssh key for the
root(!!!) user of boss- NOTE: the raspberries have to know each other in order to be able to upload/download files from each other
- It's good to name the raspberries to
boss,emp1,emp2,emp3 - generate a key via
sudo ssh-keygen -f .ssh/id_rsa
- link up the other raspberries
- exchange ssh keys with
ssh-copy-idso you can log in seamlessly! - peferably set a descriptive name for each raspberry in
/etc/hostnameso you can use that inemployees.json - set up config files in
configfolder by the examples
- I get
pygame.error: video system not initialized: did you try to run it withsudo?
- The 4 separate raspberries are linked via a dlink switch, because that was the most convinient way to link them
- The reason 4 separate board is needed is that the boards only support 1 camera at a time.
- there are many hacky solutions, this is a prototype
- there are 3 slave and 1 master raspberry. The master has the GUI running on the linked 2,2 tft screen.
- timing is solved through 3 separate GPIO channels being sent out by the master PI. This is because one GPIO output has problem driving 3 different PI's input.
ssh into boss.
./log to see the live output of all the cameras.
./status to see if all the other pi's are in
- This is my first python project.
