Control Circuits


Posted on Feb 6, 2014

This low current relay circuit is designed to be used in battery operated electronic devices. Its operating current is in micro amperes ( µA). This is done by using a bistable relay and adding some components to force the relay to behave like a monostable relay.

of a logging unit with a 2. 4GHz transmitter, and a USB-based receiver. The project includes the schematics, PCB design, firmware, software and lots of additional files and data. A wireless keylogger is a perfect solution for monitoring user activity, at very low risk of disclosure, is a purely electronic device, so no access to the operating system is required. The Wireless Keylogger consists of two main building blocks: the transmitter, and the receiver. The actual keylogging takes place in the transmitter, which is in fact a PS/2 hardware keylogg.
