In this video you will see how to make a simple wireless power transmitter and receiver. For this project you need enamelled copper wire 0.4-0.6 mm, 2N2222A transister, 27k resistor, 9v battery and ...

Wireless charging is nothing new—you may charge your phone that way every day. But in some instances, it’d be super handy to directly and regularly power devices across a gap filled with air, glass, ...

If you need to send data from sensors, there are plenty of options, including a bewildering selection of wireless methods. Trouble is, most of those protocols require a substantial stack of technology ...

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...

In many systems, transmission lines drive reactive (mostly capacitive) loads. To preserve signal integrity, you should properly terminate the lines. However, the input impedance of CMOS logic ICs, for ...

This application note describes how to build a simple and fairly low-cost wireless Bluetooth stereo audio system for outdoor use. The system has 20WRMS output power. It can be controlled either with a ...
