Skills needed to build a working Toveri

From front-end to backend

• GNU gettext
• Perl
• REST API
• HiPi
• Swig
• C
• SPI
• Ansible
• Raspberry Pi
• Linux
• KiCad
• Blender
• Soldering
• Electronic assembly

Estimated steps to production

• Ordering components from various suppliers (500-600€)
• Assembly of the PCB
• Soldering the PCB
• Making the cabling
• Disassembling and cleaning the 3D print
• Assembling the cables and components to the 3D-printed railing and enclosure.
• Installing Raspbian to the Raspberry Pi
• Setting up internet/network access
• Accessing device via remote maintenance connection
• Configuring barcode reader by reading control codes by hand.
• Installing software
• Configuring software and Server REST API
• Running hardware diagnostics
• Running software diagnostics
• Planning the deployment location
  • Proper accessible position
  • Network access
    • Toveri has a remote maintenance connection using ssh, typically this requires some firewall rules to allow inbound traffic to Toveri's port :TCP22
    • Toveri needs access to the Koha's REST API, typically at port :TCP443
    • Additionally a monitoring solution, such as Zabbix, needs extra inbound/outbound ports to be forwarded. This is outside the scope of this project.
  • Power utility access
  • Maximum distance between the exterior barcode reader and Raspberry Pi is 4m of cable.
  • Safe location for the Raspberry Pi in the interior space.
  • How to attach the device to the exterior wall?
• Executing the deployment plan
• Monitoring performance and logs
• Getting reports of device usage
• Maintenance
