This is a very exciting time for those who like to spend their downtime exploring virtual worlds. The graphics in some big-budget titles are easily approaching photorealism, and immersive multi-channel sound can really make you believe you’ve been transported to another place or time.

The aim of the project is to make a wearable t-shirt that displays an evocative graphic when air pollution is above a set threshold. The graphic is inspired by the classic game “brick breakers”, in that the car is like a paddle which spits out the exhaust (which are like balls) that “hit” pieces of […]

This Instructable describes a lower-cost, battery-powered wireless IOT sensor layer for my earlier Instructable: LoRa IOT Home Environmental Monitoring System.
