Laser harps are musical devices with laser beam “strings.” When the beam is blocked, a note is played by the instrument. Usually laser harps have the beams travel vertically in the shape of a fan or vertical lines. In this project, I built a laser harp with stacked laser beams that propagate horizontally. The beams […]

One of us (Mailland) grew up in Paris in the 1980s, surrounded by advertisements for racy “pink” chat rooms, accessible through terminals connected to France’s Minitel network. They were a lucrative part of the wider Minitel economy, which also let you send messages, check bank balances, and read news. By 2000, as the Internet displaced

A team of researchers at the ‘Georgia Institute of Technology’ has come up with a non-invasive sensor-in-a-chip that records details of the heartbeat, respiration rates, and lung sounds. It even tracks the wearer’s physical activities, such as walking. The signals are recorded in sync, potentially giving healthcare workers a detailed overview of a patient’s heart and lungs.

Similar to the earlier Lindenis V5 designed for AI video processing and 4K encoding, Lindenis has released another single-board computer that uses SoM and baseboard design for 4K camera applications called the Lindenis V536. The Lindenis V536 which runs on a new Allwinner dual Cortex-A7 processor and a single MIPI SCI interface was designed for applications that rely heavily on popular open-source

If you worked with computers back in the 1970s, there’s a good chance you used a light pen at some point: a simple input device that you’d point at the CRT screen to highlight text, choose menu options or manipulate graphic objects. Although ubiquitous in those days, the light pen lost the battle for ergonomics

Although radar is typically associated with scanning the sky, it is also used for underground purposes. Ground-penetrating radar (GPR) is utilized to send signals beneath the surface and analyze their return to determine the presence of buried objects, similar to locating or identifying distant aircraft by detecting radar echoes. This technology can be constructed using
