A Raspberry Pi can be used for a huge range of applications, but we think the most useful might be as a fart detector. Here's how to set one up.

Sleep How to Build a Consciousness Detector Why future “consciousness detectors” should look for brain complexity. Posted June 16, 2021 | Reviewed by Ekua Hagan ...

Building a machine that would detect consciousness sounds like science fiction, but the growing science of consciousness is beginning to show the way.

The easy fix for this is to simply flip off a power strip, but if you want to root out and identify the source, Popular Mechanics shows you how to build your own Electromagnetic Interface (EMI ...

Currently, MIT is marketing the detector as a learning experience for high school and college students, and its website provides detailed instructions on how to build and operate the device.

Scientists want to build a new type of detector they liken to a "cosmic car radio," that could listen to what the dark matter is saying.

They’ve developed the foundation for a powerful new detector that could identify dark matter—the invisible substance thought to make up 85% of all matter—within just 15 years.

Even when the signal is well below noise level at the detector input, it may be considerably above noise level at the output of the receiver.
