Here is a simple USB FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio by connecting it to an USB port. The circuit use no coils that have ...

The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

We are fascinated when we see machines work together, seemingly with minds of their own. The TV show “How It’s Made” became popular for simply showing how products are made in an automated factory ...

[Angelo] is only 15, but that doesn’t mean his fabrication skills are limited to Lego and K’Nex. He’s built himself an amazingly well constructed FM transmitter that’s powerful enough to be received a ...

A key component for these wireless battery power chargers is a power transmitter IC that offers robust, standalone applications capable of transmission distances up to 15mm and tolerance of poor coil ...

Wireless Power Transfer relies on magnetic induction between a planar receiver and transmitter coils. When the receiver coil is positioned over the transmitter coil, magnetic coupling occurs when ...

AM radios are relatively simple devices, and building one is a good way to start exploring the world of radio communications. [GreatScott] does exactly this in the video after the break, building both ...

An electronic device is susceptible to Electrostatic Discharge (ESD) damage during its entire life cycle, including the phase from the completion of the silicon wafer processing to when the device ...
