Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

We present the first measurement results for silicon-germanium (SiGe) heterojunction bipolar transistors (HBTs) and SiGe BiCMOS circuits operating in the sub-1-K regime. Robust transistor operation of ...

Given the performance decay of high-power light-emitting diode (LED) chips over time and package condition changes, having a reliable output light for sensitive applications is a point of concern. In ...

A tube that runs under the nose is often associated with illness and may deter adoption. The device also doesn't account for mouth breathing and can slip out of place when sleeping.
