Computer microphones Learn how to interface electret and dynamic microphones to the standard computer sound card. Metal detectors Theory of operation and schematics of the most common metal detectors used today: Very Low Frequency (VLF), Pulse Induction (PI) and Beat-Frequency Oscillator (BFO). Wireless microphone The wireless microphone transmitter can be built in an afternoon with simple, affordable and widely available parts.
We are gathering and investigating information about interfaces of modern and obsolete electronic hardware including pinouts of interface ports, expansion slots, other connectors of computers and other electronic devices. Information about functions of pins in connector (pinout) is essential for everyone who wants to investigate modern computer hardware, explore the way it's works, connect various devices to computer, produce DIY electronic devices. Our handbook features 1610 documents with:
