Wireless Power Transfer In 3d Space - The main objective of this project is to develop a system of wireless power transfer in 3D space. The air core transformer operating near 40 KHz is the main concept for wireless power transfer, as one cannot transfer 50 Hz ac power by air core. The secondary coil in resonance develops a voltage of 40 KHz at about 12 volts when it is taken over the primary coil. The output of this secondary is given to a 10-watt lamp that glows at considerable distance from the primary coil.

Wireless RF PWM Dual Motor Controller - This is a very simple Wireless RF transmitter circuit that consists of the Holtek HT-12E encoder chip and AM 418MHZ-transmitter module (WZ-X01, other similar device can be used) . Using the hybrid RF xmit/receive modules make building the RF remote control a lot easy __ Contact: info @ wzmicro.com
Wireless Telephone Eavesdropper Electronic - The IR transmitter connects to a telephone circuit, and transmits both sides of all telephone conversations to any line-of-sight location, within 40 feet. No power is taken from the central office, as long as all phones remain on-hook. The current flows through the phone and back to the central office
Wireless Temperature & Humidity Sensor with USB - this project is based on obdev's Remote Sensor example and their firmware-only USB implementation; the main change is the replacement of the analog sensors with a Sensirion SHT11 digital temperature and humidity sensor
Wireless Temperature Monitor Has Data-Logging Capabilities - 01/19/12 EDN-Design Ideas You can make a wireless temps system with two ICs. You can use a local temperature sensor and an ASK (amplitude-shift-keying) transmitter/receiver pair to design a simple wireless temperature-monitoring system with data-logging capabilities. A microcontroller processes and displays the temperature reading to the user. The microcontroller’s onboard UART (universal asynchronous receiver/transmitter) also allows for data-logging applications Design by Tom Au-Yeung and Wilson Tang, Maxim Integrated Products, Sunnyvale, CA
Wireless Volume Control - 17-Aug-11 -Design News: Andrew Morris decided the usual wireless volume controls don’t offer enough functionality, so he created the ultimate volume control that connects between a computer or MP3 player and an amplified speaker system. __ Designed by Andrew R. Morris, Gadget Freak-Case #192
Wireless Weather Station. Part 1 - In the Midwest, the main topics of conversation may include the local football team or how the crops are doing. Inevitably though, the conversation always leads to the weather. Most of us take the weather for granted __ Designed by Jerry Wasinger
Wireless-Powered LED - Wireless power is transferred from transmitter to receiver coil using inductive coupling principle. For wireless power transfer to work efficiently, frequency of the transmitter and the receiver must be tuned to...__ Electronics Projects for You
Z1 Small 3-wheel ROBOT with Infrared eye - Z1 is a small three wheel robot that avoids obstacles which it senses with its active infrared sensors. Each rear wheel has its own motor, the single front wheel is not powered. The robot steers "like a tank" by rotating the rear wheels in opposite direction __ Designed by © 2008 Ayman CDMA |
