Stereo FM Transmitter Circuit using IC BA1404
The following posts explains how to build a simple to build FM stereo transmitter circuit using IC BA1404. About the IC BA1404 An exceptional stereo audio FM wireless transmitter circuit is presented below. The circuit relies upon the IC BA1404 from ROHM Semiconductors. BA1404 is a monolithic FM stereo modulator which includes integrated stereo modulator, […]
Illuminating DRL and Turn Lights with Single Common Lamp
In this article I have explained a simple circuit for enabling the turn signal lamp of any car to carry out a two-way function of DRL lights as well as well the stipulated turn lights. The idea was requested by Mr. Artem. Technical Specifications Thank you for your fanaticism with electronics, this is really noticeable […]
LED Obstruction Light Circuit
Obstruction lights are warning lights that we see at the top of tall structures like towers and skyscrapers, installed for indicating the aircrafts and other flying objects about these obstructions. These lights alert the flying aircrafts regarding the minimum height they should maintain above these tall structures to avoid a possible collision and accidents. Obstruction […]
Triac Battery Charger Circuit
A triac based battery charger replaces a normal relay for automatically cutting off power to the battery very efficiently. In this post I have explained a simple a battery charger circuit using a triac auto shut-off facility. The circuit can be used for charging any high current, high AH types battery with a full-charge auto […]
SPDT Relay Switch Circuit using Triac
An efficient solid state single pole double throw or SPDT switch can be built using triacs for replacing a mechanical SPDT. In this post I have explained a simple solid state triac SPDT relay circuit, using an optocoupler and a couple of triacs, which can be used as an effective replacement for mechanical relays. The […]
