We are working on system, that will help tourists in cities to get information about city more easily.
|
|
|
|
## Hardware
|
|
- Raspberry PI (for now tested only on rpi4. Works on rpi zero too, but it will be slow if more devices are connected)
|
|
- External/Internal WiFi antena
|
|
|
|
## Software
|
|
- python 3.9.2 compatible server with basic web interface
|
|
- Kotlin based mobile app
|
|
|
|
## Install
|
|
Wikispot is in testing stages, but it is possible to install it using our .img file (link coming soon) based on DietPi or custom script.
|

|
requirements:
|
|
1. WikiSpot image file (download: *soon*)
|
|
2. MicroSd card (recommended: >=16GB, :exclamation: ALL DATA STORED ON SD CARD WILL BE FORMATED :exclamation:)
|
|
3. BalenaEtcher (or another sd card flasher) *link:* https://www.balena.io/etcher/
|
|
4. SD card reader
|
|
|
|
|
|
Install:
|
|
1. Download all required files (wikispot.img and balenaetcher) and install BalenaEtcher
|
|
2. Insert SD card into computer/reader, open BalenaEtcher -> chose Flash from file -> chose downloaded wikispot.img -> Select your sd in *Select target* -> Flash!
|
|
3. :exclamation: WINDOWS will show unformated drive. Cancel it. It is because of uncompatible format for windows :exclamation:
|
|
4. After flashing open partition *boot* (should apear as USB), find file *dietpi.txt* and open it in text editor.
|
|
- Accept license by changing `AUTO_SETUP_ACCEPT_LICENSE=0` to `AUTO_SETUP_ACCEPT_LICENSE=1`
|
|
- Change name of WikiSpot `AUTO_SETUP_NET_HOSTNAME=WikiSpot-CHANGE_ME` by changing only *CHANGE_ME* or leave *CHANGE_ME* for random number name *WikiSpot-54346
|
|
- You can set static ip address by changing `AUTO_SETUP_NET_USESTATIC=0` to `AUTO_SETUP_NET_USESTATIC=1` And entering your setting into required lines.
|
|
- If you want to use computer vision plugin with rpi camera set `ENABLE_COMPUTER_VISION_PLUGIN=0` to `ENABLE_COMPUTER_VISION_PLUGIN=1` (*recommended only on RPI4)
|
|
- If you want to use RPI as access point to WikiSpot change `#AUTO_SETUP_INSTALL_SOFTWARE_ID=60` to `AUTO_SETUP_INSTALL_SOFTWARE_ID=60`
|
|
- *wifi setup in testing*
|
|
5. :grey_exclamation:For advanced users:grey_exclamation: You can now change contens of WikiSpot server in `/boot/WikiSpot`according to an example in server filesystem
|
|
6. Eject sd card from computer, insert it in Raspberry Pi and power it on. :bangbang:Raspberry Pi needs to be connected to intenet via Ethernet (*wifi coming soon*) othervise the setup will crash.
|
|
7. The setup will take approximately 25-40 min (RPI 4b (2gb) and 70 mb download speed)
|
|
8. Done you can start using WikiSpot and edit contents of WikiSpot with our app (*coming soon*)
|
|
|
|
|
|
### Script install
|
|
*coming soon*
|
|
|
|
|
|
### Manual install

To manualy add new file to server (on setup or via ssh) add file to `server_directory/files`
|
|
and add record for file into `files` list in `filesystem.json`. :exclamation:do not forget "," after last record:exclamation:

If you want to manually add server on first setup or via ssh fill heartbeat table like this.
|
|
|
|
```
|
|
"heartbeat_table": { # Saved servers
|
|
"ID": [1], # ID of server as integer (number)
|
|
"IP": ["192.168.1.2"], # IP of server as string
|
|
"location": [""], # Empty string as placeholder. location will be downloaded after first connection
|
|
"file_system": [""], # Empty string as placeholder. filesystem will be downloaded after first connection
|
|
"last_heartbeat": [10] # After how many seconds will server try to connect for the first time
|
|
}
|
|
```
|
|
|
|
:bangbang:If the server will be offline for long time (heartbeat + offline heartbeat) it will be removed from heartbeat table. If the save function is disabled server will trying to connect after restart:bangbang:
