| Information | System for uploading pictures from floppy to Kiekjes |
| Status | Completed |
Idea
Mr. bef0re has brought a nice Sony Mavic floppy camera to hackerspace. Floppy drives are always unstable, and it took some time to upload photos from camera to PC. After some talks, the idea to upload stuff from this cam to Kiekjes was born
Realisation
Raspberry Pi, the one hanging on the wall, has a floppy drive attached. It constantly checks for floppy disk every time spaceinvader makes a move. If found, it uploads stuff first to temp directory, then from temp directory to Kiekjes server.
Usage
Usage is pretty simple: you just insert the floppy disk into floppy drive. If everything goes as planned, some LEDs will light up. Their number is equal to number of files on floppy. All files will be deleted. So don't put weird floppies in. If anything goes wrong, the cross will be displayed and the script will retry to get photos.

Tech details
Script listens for specified symlink for device connection, after what it monitors the size of connected device. When it's not zero (floppy disk inserted), it processes data on floppy. All logs are in /var/log/syslog and in service status. Service is called floppy-reader. Script can take multiple parameters:
