Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. The project was started in 2013 by Dave Hakkens and is now in its fourth iteration. It relies on a series of machines and tools which grind, melt, and inject recycled plastic, allowing for the creation of new products out of ...
Freeduino – an open-source physical computing platform based on a simple I/O board and a development environment that implements the open source Processing / Wiring language. Also clones of this platform including Freeduino. Tinkerforge – a platform comprising stackable microcontrollers for interfacing with sensors and other I/O devices
The Fido explosives detector is a battery-powered, handheld sensory device that uses amplifying fluorescent polymer (AFP) materials to detect trace levels of high explosives like trinitrotoluene (TNT).
Ghost imaging (also called "coincidence imaging", "two-photon imaging" or "correlated-photon imaging") is a technique that produces an image of an object by combining information from two light detectors: a conventional, multi-pixel detector that does not view the object, and a single-pixel (bucket) detector that does view the object.

Gamma-ray radiography systems capable of scanning trucks usually use cobalt-60 or caesium-137 [6] as a radioactive source and a vertical tower of gamma detectors. This gamma camera is able to produce one column of an image. The horizontal dimension of the image is produced by moving either the truck or the scanning hardware.

Kismet differs from other wireless network detectors in working passively. Namely, without sending any loggable packets, it is able to detect the presence of both wireless access points and wireless clients, and to associate them with each other. It is also the most widely used and up to date open source wireless monitoring tool. [citation needed]
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic ( photodetectors ). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [ 2 ]
