Device Control using DTMF -  Controlling devices using switches are common.  From a few decades controlling devices using remote control switches like infrared remote control switch, wireless remote control switches, light activated switches are becoming popular.  But these technologies have their own limitations.  Laser beams are harmful to mankind.  __ 

DIY remote control based on PIC -  Control up to 8 devices by this easy constructable remote control.  it can work as a radio or infrared remote control, depending on the components.  Each device output can be configured to be momentary (turned on while you press the button) or latched.  Latched outputs can be toggled on/off by one button per channel, or turned on and off by two buttons per channel __ Designed by Peter Jakab

D-I-Y remote control for a Model train layout -  All you need is a picaxe, some code and a pair of pre-built UHF modules (plus a few minor parts.__ SiliconChip

Downed Model Locator -  The circuit draws 1mA (!) when idle and 4 mA when buzzing.  I'vebeen using large peizo buzzers (see part numbers below) because they are light and loud, and the 6 volt electromagnetic buzzer where weight is not so much of a concern.   __ Contact IQ Technologies

Downed Model Locator II -  Here is another device to help you locate your downed R/C sailplane in the bushes and weeds.  Similar to the other design, this circuit plugs into a spare servo socket on your receiver, and it is a pulse omission detector.  The alarm sounds when pulses originating from your transmitter are no longer being received--turn off your transmitter to turn on the  __ Contact IQ Technologies

DTMF Radio Remote Control -  Here is a circuit of a remote control unit which makes use of the radio frequency signals to control various electrical appliances.  This remote control unit has 4 channels which can be easily extended to 12.  This circuit differs from similar circuits in view of its simplicity and a totally different concept of generating the control signals __ Designed by Radioland.net

Fire Stick infrared Remote Control -  This article will show you how to build your own version of the Fire-Stick infrared remote control system.  The Fire-Stick has been an extremely popular, and HOT selling item here at Rentron.  com for quite a long time.  The LiTEON infrared receiver modules originally designed-in to the Fire-Stick have been discontinued, and forced us to re-design the original circuit boards.   __ Designed by Reynold's Elec

Four-Channel Remote Control -  You can construct your own long range infrared (iR) wireless remote using Motorola's MC145026 emitter and MC145027 detector chips.  With your remote you can control devices up to 20 feet (7 meters) away.  it operates similiarly to a TV remote.  You just point the emitter at the detector, push a transmit button.  The detector then interprets your data signal.  You can use this circuit to remotely turn on/off devices (like a motors, relays, home appliances).   __ Designed by Boondog web site

Four-way remote control uses series transmission -  01/18/01 EDN Design Ideas:  A simultaneous fourway remote-control system adheres to size, cost, and reduced-complexity   constraints and uses a series transmission to drive parallel loads (Figure 1).  You can use.   PDF has several circuits, scroll down.    Design by JM Terrade, Clermont-Ferrand, France

Garden Timer with Remote control -  Few years ago we control the lights in the garden with a automatic-timer-switch, very nice but when the evening gets longer or shorter we had to adapt the timer each week.  in that time I came in contact with programming microprocessors so my first project was born.  The first garden timer was a simple 1 output.  The timing was controlled by the PIC  and every month I had to change the minutes.  So back to the table and design the second garden timer able to control 3 relays, left, mid and right side of the garden.  it provided also 4 modes: – always off – always on – from dusk to dawn – from dusk to timer and the timing was dedicated to a RTC DS1307.  __

Infrared Receiver for Sony Remotes -  infrared remote controls are using a 32-56 kHz modulated square wave for communication.  These circuits are used to transmit a 1-4 kHz digital signal (OOK modulation) through infra light (this is the maximum attainable speed, 1000-4000 bits per sec).  The transmitter oscillator runs with adjustable frequency in the 32-56kHz range, and is being turned ON/OFF with the modulating signal, a TTL voltage on the MOD input.  On the receiver side a photodiode takes up the signal.  The integrated circuit inside the chip is sensitive only around a specified frequency in the 32-56 kHz range.  The output is the __ Designed by Peter Jakab
