This circuit will allow the user to lock his car ignition using his phone Bluetooth, meaning the ignition can be locked/unlocked only through a specific code from the user’s cellphone Bluetooth. Overview In one of my earlier posts I have already explained how to hack a Bluetooth headset and use it for any desired switching […]

2.4 GHz 10 Channel Remote Control Switch Circuit
In this post I will show how to construct a 10 channel remote control switch circuit based on ISM (industrial, Scientific and Medical) band. Introduction The ISM band is operated at 2.4 GHz, which can be used without licensing with reasonable power output. The proposed project is general purpose ON/OFF wireless switch, which can be […]
Arduino IR Remote Control Circuit
In this post I will show how to construct a customizable Arduino based IR (infrared) based wireless remote control switch, which consists of IR remote and a receiver, you may modify according to your needs. In the later part of the article I have explained about an upgraded foolproof version of an IR remote control […]
Remote Controlled Ceiling Fan Regulator Circuit
In this article I have explained a few simple infrared TV remote controlled fan regulator or dimmer circuits using ordinary parts such as a 4017 IC and a 555 IC. The first concept uses a standard MOSFET based SSR for controlling the fan load and for easy and clean PWM signal operation from the IC […]
Quadcopter Remote Control Circuit without MCU
Although a quadcopter remote control circuits can be very easily procured from the market or from any online store, an avid electronic hobbyist is never allowed to learn how actually these function and whether or not these can be built at home? In this article I have explained how to build a simple quadcopter remote […]
Remote Control Circuit Using FM Radio
In this post I have explained how to build a simple FM remote control circuit for toggling small AC loads such as lamps, fans etc using an ordinary FM transmitter circuit and a modified FM radio circuit. This remote control system enables the user to get an ON/OFF control on any desired appliance, by simply […]
