We’ve seen no shortage of projects that use the ESP8266 or ESP32 to add “smart” features to existing home appliances, often by pairing the microcontroller with a radio or IR transmitter. If your ...

The transmitter project provides 2 channels for transmitting and receiving which operates on the 418MHz frequency. The circuit utilizes a few ordinary components to create the RF transmitter and RF ...

Wireless radio transmitters have evolved over the years from real IF (intermediate frequency) transmitters, to complex IF transmitters, to zero-IF transmitters. However, there are still limitations ...

Members can download this article in PDF format. In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to ...

One of the great things about the Hackaday community is how quickly you find out what you don’t know. That’s not a bad thing, of course; after all, everyone is here to get smarter, right? So let’s ...

Powercast will be at CES 2023 with its Ubiquity RF power transmitter, a device it hopes can make a pervasive presence of RF wireless power in smart homes. With this transmitter, Powercast claims to ...

Powercast has unveiled its Ubiquity wireless power transmitters, which use radio frequency (RF) power to charge devices over the air. The Pittsburgh, Pennsylvania-based company showed off its Ubiquity ...

Very seldom do I catch myself uttering the word "genius" silently to myself as I'm reviewing a piece of equipment. I have to say, I had my doubts about the Remote Control Extender when it was first ...
