While investigating the RF interface used in a series of cheap “smart” solar inverters [Aaron Christophel], created an Arduino library to receive inverter telemetry using a $2 RF module.

RF phase shifters are twin-ported devices that alter the phase of an output signal in response to an external signal. Variable phase shifters change the output signal phase by applying a variable ...

RF waveguide phase shifters are two-port waveguide modules that alter the phase of an output signal in response to an external signal. They are made of aluminum, brass, bronze, copper or silver ...

Only single-phase, grid-tied and hybrid inverters for homes in the US were reviewed. DC power optimizers weren't included in the reviewing and scoring of any of the string inverters mentioned in ...

Atess Power, a Chinese PV inverter manufacturer, has released a new series of all-in-one hybrid inverters. Its HPS100/150HV inverters are designed for commercial applications. Depending on the ...

Even if your CPU or other device needs an external clock, you just slap in an inverter, a crystal, and two capacitors together, and you are done, right? Maybe not. [Dave Collins] got interested in ...

(Radio Frequency remote control) A handheld, wireless device used to operate audio, video and other electronic equipment using radio frequency (RF) transmission. Unlike the common infrared (IR ...

Additive manufacturing (AM), otherwise known as 3D printing, is an incredible process that creates three-dimensional, ...
