Overview

COVID-19 shelter-in-place orders left Mapbox Policy Lead Tom Lee, his wife, and his sister-in-law with three children to manage. Combining their households made working from home possible, but the morning minutes before sister-in-law’s arrival were often frantic. So he dusted off some hardware and re-wrote some open source software to build a hands-free in-home alert system to signal when the family car was approaching home – and childcare support was on the way!

When the family car is moving, a light turns on, and an antique electrical meter points to 30...20...10 to show the estimated minutes until the driver arrives. This DIY appliance helps his household manage childcare routines like clockwork.

Tom will discuss the ins and outs of physical computing, microcontrollers and using Mapbox APIs for ambient displays. He will not discuss whether using precious evening hours to sleep instead of code would have been better for his and his family’s sanity.

Materials:

  • Arduino micro-controllers (ATMega328P & ESP8266 based)
  • Raspberry Pi computers (gen 1 & 3)
  • Dongle device in car (with SIM card and cellular service)
  • Light device with bulb & solid state relay
  • Antique electrical meter (if you’re that steampunk) 

You’ll learn how to...
