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, ...

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 ...

Here is a wireless FM Transmitter which uses RF communication to transmit the medium or low power FM signal with the maximum transmission range of around 2 km. Here is a wireless FM Transmitter which ...

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 ...

[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 ...

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 ...

Alpha and Omega Semiconductor has released the AOZ32034AQV, a new product in the family of coil drivers for wireless charging transmitter circuits of up to 50W Packaged in a thermally enhanced QFN 4 x ...

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 ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

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 ...
