Meeting Notes October 31st, 2025

Key Decisions

• 1 Raspberry Pi per stair
  • This give us additional flexibility interfacing with different sensors
  • This should still be well within budget
  • Can scale down into lower Pi models if need be
  • Can communicate well via web server
• Time of Flight sensors
  • We already have a prototype
  • See Dopamine Machine
  • Should support the range we need
• User Interface
  • We can also use a separate Pi to run the user Interface
  • At previous meeting, the software team decided on using python + flask for display and communication
  • This should easily communicate with the other Pi, via HTTP, or another protocol
• Working budget
  • $5,000 USD

Actions Taken

• Software team mostly out today
• Hardware team began work on prototyping 1-pi-per-stair model
