This experiment revisits a long-running attempt to build a working camera lens and image system from scratch, then upgrades ...

The Raspberry Pi has brought digital camera experimentation within the reach of everybody, with its combination of an accessible computing platform and some almost-decent camera sensors. If ...

This all-purpose presence sensor is a master at monitoring indoor activity and linking it to smart home features you already use. Tyler has worked on, lived with and tested all types of smart home and ...

We are all familiar enough by now with the succession of boards that have come from Raspberry Pi in Cambridge over the years, and when a new one comes out we’ve got a pretty good idea what to expect.

PCWorld explains how to create an affordable CO2 air quality monitor using a Raspberry Pi and MH-Z19C sensor for under $40. This DIY project helps monitor indoor air quality since high CO2 levels ...

"Earlier works introduced other methods to search for light dark matter, which for instance relied on an elongated detector or a classical array of detectors," explained Fukuda. "However, these ...

Researchers in Sweden have unveiled a way to create high-performance electronic electrodes using nothing more than visible light and specially designed water-soluble monomers. This gentle, ...

Presence/motion sensors are one of the best ways to make automations feel more natural, but most of them run on batteries and eventually have to be swapped. That’s one of the main reasons I really ...

Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and converting it to electrical signals. So when the Sun's rays reach damaging levels, ...
