This document is a guide to making a portable device which can be used to monitor the air, in terms of PM2.5.

These tiny particles can come from a variety of sources and could be harmful. This device will indicate when the relative number of particulates in the air is high.  It could be used to monitor the air in a workshop.

This resource contains a set of instructions to construct and operate a model wind tunnel which can be used as part of the F1 Cars Project. The guide is accompanied by a set of files to enable components to be produced using either a 3D printer or, for larger sheets materials, using a laser cutter.

A list of test machines that could be used to carry out portable appliance testing (PAT).
