Omnik Inverter Off It’s Cloud and on My MQTT

I have a solar power installation using an Omnik string inverter. Omnik is a China based manufacturer of PV inverters and they make extremely efficient devices. Optionally, you can install a WiFi module to make it “connected”. I am very content with the device, with two notable exceptions. It “phones home” to a China based …

THE FASTEST FOURIER TRANSFORM IN THE WEST

THE FASTEST FOURIER TRANSFORM IN THE WEST

An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical insight is extremely helpful when processing signals digitally, and allows a simpler way to implement frequency-dependent filtration in a digital system. [klafyvel] needed this capability …

WORLD’S-FIRST-MOS-FET-RELAY-MODULE-“G3VM-21MT”-WITH-SOLID-STATE-RELAY-IN-“T-TYPE-CIRCUIT-STRUCTURE”

WORLD’S FIRST MOS FET RELAY MODULE “G3VM-21MT” WITH SOLID STATE RELAY IN “T-TYPE CIRCUIT STRUCTURE”

OMRON Corporation of Kyoto, western Japan globally released its new MOS FET (*1) relay module “G3VM-21MT” on December 2, 2019. The product is the first electronic component in the world (2) to adopt a “T-type circuit structure” (3). With a T-type circuit structure consisting of compact-size and longer-lifecycle solid-state relays that output signals using no physical contact, the relay …
