People Counter

PROPOSAL: People Counter would track how many people are in the space for occupancy safety monitoring. DOERS: User:Culteejen, User:CRImier

Proposals to improve Noisebridge. Edit

Culteejen Proposal

Proposal for y'all:

• As mentioned before, I wanted to create an app that can show people if / how many people in the space. I whipped up the server side stuff tonight (I tested it on my bot channel) to demonstrate what it would look like.
• I'm thinking there would be something like a button you would press at the space to increment / decrement the number, and it would update the number on the server
• screenshot prototype

CRImier Proposal

• It's an entry panel kiosk, with a quick (and, hopefully, intuitive) workflow to answer "entering/leaving, how many people, for how long, which rooms" questions
• Demo video
• Uses a few custom PCBs, the pads are captouch (the heart board is a TTP229 breakout), designed to be easy to source and assemble independently
• It runs on ESP8266/32, MicroPython firmware is complete for everything except the actual "send data somewhere" part because I never defined the API I'd be interacting with.
• The firmware reads buttons and processes them according to the planned UX flow, and has quite a few nifty features for usability. Also, designed to collect anonymous data, of course
• The panel design is A4-sized and designed for 3mm lasercut wood, so, should be easily cuttable on a K40. The touch pads have 2mm acrylic spacers in front of them - also easily lasercuttable!
• So if such a workflow would help you, I can publish the non-yet-published design files, and mail the assembled&tested custom PCBs I have if that'd be helpful
• I've designed this to be useful for other hackerspaces, it's just that I've never gotten to actually getting my shit together and publishing it all
• Lasercut button box prototype picture
• Box internals picture - with a random ESP32 devboard
• MicroPython code for an ESP8266/32 controller
• Touch electrode PCB design - FR4 pieces can be used
• TTP229 breakout PCB design - a generic TTP229 (16-key capacitative touchpad breakout) can be used instead
• ESP12-based controller PCB design - a generic ESP8266/32 devboard can be used instead
• Sample JSON output:

  {'time': 0, 'locations': [2, 1], 'guests': 2, 'leaving': false}'
