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 ...

A piezo disk transducer is a handy part for reproducing beeps and boops, and can also function as a rudimentary microphone. Being a piezoelectric element, it can also generate usable power. Enough to ...

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 ...

[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 ...

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 ...

In the first three installments of this series, we discussed whether or not an old transmitter was even worth fixing, followed by some techniques I ve used to repair high-voltage power supplies, ...

DALLAS, USA: Texas Instruments (TI) today introduced its next-generation wireless power transfer circuit with foreign object detection that will allow designers to bring to market 3-coil, 5-V and 12-V ...

Expanding its growing portfolio of wireless charging technology for portable electronics, Texas Instruments Incorporated introduced the bq500211, the industry's first wireless power transfer ...
