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

Questions
How big is the Old PCB?
It measures 59.7 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Old use?
39 parts, built around the DS18B20+, EC2-3TNU, AST-1732MR-R and NHD-0420CW-AB3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Old KiCad files?
From the Hypernova-Oy/emb-toveri repository on GitHub, at the commit this page was made from: the board is KiCad/authenticator/old.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Old design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
