Raspberry Pi Pico microcontrollers come with a variety of different features for a few bucks, and a few interesting ...

In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of ...

If you happen to be in the market for a small artificial sun, you may be interested to know that for about $1300, you can get a tennis-ball-sized LED array that outputs 120,000 lumens.

A compensated Pt100 RTD circuit has 1 mV/°C DMM output, with linearization via positive feedback, pending Part 2 ...

If you're savvy and want to do a bit more home monitoring, these interesting sensor ideas might be worth trying.

Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing ...

There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or ...

They go by names like “Alto,” “Irene,” and “Shoeshine,” but for years, outdoor, non-feral cats have largely been invisible inthe North Texas Dallas city code. Advocates for so-called “community cats” ...

Abstract: Global warming and the associated increase in heatwaves have made the prevention of heat-related illnesses such as heatstroke a critical global challenge. Monitoring physiological indicators ...

This code example demonstrates a CAPSENSE™-based proximity sensing design to control the brightness of an onboard LED. It helps to learn how to design a proximity sensor using a PSoC™ 4 device, and ...
