    • end up using modeswitch for switching modes and back to sakis, because wvdial doesn't assign dns if connected to eth0, so no ssh
29. Implement backend restful API using PHP https://github.com/alixaxel/ArrestDB
    • modify htaccess file
30. Modify MainScript to upload via 3g to server backend http://fusion94.org/lcdchargen/
31. Create frontend for the backend
