Here’s how you might be able to ditch the wiring connection on your next Jeep Wrangler’s removable doors but keep power ...

How to Make Wireless Power Transmission 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 ...

The wireless transmission is being demonstrated by the simple circuit which can send Morse Code signals over distances of a few meters to any AM radio. The Morse Code signal is considered as a ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Using optical wavelengths rather than RF is bringing the long-sought goal of transmitting useful power levels closer to ...

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 ...

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, ...
