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 simpler to make. The scientists hope the breakthrough could lead to cheaper ...

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 ...

We may receive a commission on purchases made from links. Smart sensors aren't just for turning lights on when you walk into a room. There's all manner of fun and clever ways to use them around your ...

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 ...
