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 ...

Back in December, Godox unveiled the LiteWafer UP150R Full-Color LED Panel, which is essentially a 2x1-sized panel. Now, they are offering a two-light kit ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

By controlling magnetic fields using light, a team of researchers led by NTU scientists has solved a long-standing challenge ...

Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins ...

They claim to fix fine lines, blemishes and redness – but which stand up to scrutiny? We asked dermatologists and put them to the test to find out The best anti-ageing creams, serums and treatments ...
