Experience low power, high security, and reliable performance with PolarFire® Core & SoC FPGAs. A maker recently engineered ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

EPFL researchers have developed a light-based method that can produce proteins that switch states, respond to signals, and even compute, using light and the cell cycle.

A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

When automating your smart home, much of the attention centers on cameras and lights, but I believe HomeKit door sensors are arguably among the most critical devices to add to your setup. I’ve written ...

Most modern cars have tire pressure monitoring systems (TPMS), which will alert you if your tires need air. While most of the readings they give are accurate, they can still fail like any other part ...
