This article shows you how to build a very simple FM transmitter from thirteen components, a Printed Circuit Board (PCB) and a 9v battery. This project was designed to be mounted on a PCB, however you don’t have to. You could construct the project on Vero board (strip board) or any other 0.1” pitch style

On May 17, 1902, a Greek archeologist noticed precision gear wheels embedded in an ancient artifact of corroded bronze and wood. The device would come to be known as the Antikythera mechanism, the oldest known complex scientific instrument. Discovered in 1900 on the wreck of an ancient Roman merchant vessel near the island of Antikythera,

To reach a maximum mechanical stability, many Sonitron piezo components are now available even with a foam tape. Sonitron piezo components feature a high reliability, resistance to harsh conditions and also to vibrations. Despite these features, usually one of the weakest points (as for the vibration-resistance) is the joint of leads with a PCB. That´s

This time, simple project that i made from simple need. Simple, cheap and functional regulated power supply 1,25V to 15V, two separately regulated positive lines and two negative. This power supply uses LM317 and LM337 integrated circuit stabilizers – or their stronger versions. Galvanically separated lines can be connected in various configurations. There is no

I have been looking for a good stereo amplifier circuit diagram for a long time. I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or

Traditionally, switching DC/DC converters (voltage regulators) were controlled using analog techniques because these were simple to implement and helped to maximize the power supply’s efficiency. Digital components were too slow and power greedy to challenge analog dominance. However, over the past several years the introduction of high-speed, low power consumption and inexpensive silicon has rekindled

Introduction This RFID reader works with 125 kHz tags in credit card size shape cards and with 125 kHz key fobs (picture 1). The EM4100 protocol is used. When you approach an RFID Tag close enough (4-5 cm) to the reader’s coil (L1) the reader will read the 10-digit unique ID of the Tag and transmit it
