This document describes the Video Village project, which projected video content onto the windows of an abandoned housing project in Spartanburg, South Carolina. It discusses the technical implementation including using Raspberry Pis to schedule and play videos, Django and AWS for the scheduling interface, and Ansible for software updates. Challenges addressed were synchronizing time codes between Pis, remote access after initial installation, and adapting to the environment. The goal was to tell stories from the local community and engage residents through creative public art.

Bloomberg Public Art Challenge The City of Spartanburg was selected as one of four cities to participate as part of the Bloomberg Philanthropies Public Art Challenge, a new program to support temporary public art projects that celebrate creativity, enhance urban identity, encourage public-private partnerships, and drive economic development. Seeing Spartanburg in a New Light brings nine temporary art installations to public spaces in ten neighborhoods throughout the city.

- 15. Projector Control Serial RS232 Control to Turn on/off projector Warm up time
- 16. Projector Control import serial CMD_ACK = 'x03x14x00x00x00x14' ERROR_STATUS_CMD = 'x07x14x00x05x00x34x00x00x0Cx0Dx66' POWER_ON_CMD = 'x06x14x00x04x00x34x11x00x00x5D' POWER_OFF_CMD = 'x06x14x00x04x00x34x11x01x00x5E'

- 18. Testing and configuring the system Trial Run Too much power for the building
- 19. Time code synchronization Found out that as we played videos we needed to synchronize the pi’s to play at the appropriate times.
- 20. Time code synchronization Used NTP to sync time on Pi’s Scheduler to run tasks each second
- 21. Software update No access to Pi’s after initial install
- 22. Software update Ansible for running update script
- 23. Inside the building Very “rustic” environment Hot - we sensed temp on the Pi’s to see how hot
- 24. Lessons Learned
- 25. Tools we liked We used Slack for asynchronous team interactions and for voice calls
- 26. Tools we liked Avoided tendency to write/do everything from scratch Secure tunnels allowed for remote management and troubleshooting Ngrok quoted a fixed fee for duration of project
- 27. Watch out for Not all RS232 USB cables are created equal
- 28. Watch out for Be sure to consider reboots, hardware replacement, processing stopping, etc.
- 29. Watch out for Polling for video schedules and caching helped out during periods when Internet connectivity was lost
- 30. Working together we can make a big impact

- All the 52 Pi’s need to be synchronized Video is played via OMX player, some delay happens (loading cached videos from memory card) No real time clock on Raspberry Pi We sync’d time using ntp and included a very simple scheduler on the Pis capable of running tasks each second
