Switch ON/OFF any home appliances with the help of IR Remote. Upto 16A depending upon Relay ratings.
Step 1: Parts Required
3way Terminal block x 3Schrack SPDT 16A 24VDC Relay x 31N4148 Diode x 3BC547 Transistor x 33way Berg strip x 110KOhms Resistor x 5470Ohms Resistor x 55mm LED x 33mm LED x 1TSOP 1738 x 1LM7805 IC x 1 (+ its filter parts - 470microfarad 50V electrolytic capacitor, 10nanofarad ceramic capacitor x 2, heatsink if necessary)LM7824 IC x 1 (+ its filter parts - 2200microfarad 50V electrolytic capacitor, 330nanofarad ceramic capacitor, 100nanofarad ceramic capacitor )Programmed PIC12F629 IC (Program Included)8Pin IC Holder240VAC to 24VDC 1A Adaptor + its female
A strip board to accommodate aboveA Plastic Box to accommodate above + small screws and nutsSONY REMOTE
Step 2: Programming IC + Hex file
Important part is to program the IC.
Use pickit2 or pic serial programmer to code the 'kumir.HEX' file into the IC.
Simple step, if you are in doubt here, give it to some electronics project shop and program it.

Step 3: Breadboarding
Use schematic and breadboard and feel the output.
Here used LM7824 to get 24VDC for steady driving of the relay.
Here used some spare relays and berg strip replaced by a push switch for testing in breadboard.
Step 4: Stripboarding
This is totally of soldering skills and the layout is of own taste.
Find the pictures.
Insert jumper and configure for any 3 button on any SONY REMOTE.3 buttons will be stored in the IC, use it for switching the appliance.Remove the jumper and use the appliance.
Step 5: 240VAC Circuiting
In order to function in both relay and switch, replace normal SPST switch to SPDT i.e Two way switch, for the appliance.so when 24V adaptor is switched off the appliance will toggle ON of OFF, so that case it can also be operated by SPDT switch.
We have a be nice comment policy. Please be positive and constructive.

Hi, I'm doing a kind of similar project, but I'm using Bluetooth and my circuitry is different. But you are putting a 24 volt regulator in series with the rest of your board while your power supply outputs 24 volts. A regulator always has a certain dropout voltage, that's the voltage it will consume for it self, independent of the power supply. You won't get a steady 24 volt out of the regulator if you measure it, but probably something like 22 volt (not that your relays care, they have a certain margin of a couple of volts). But I suggest you remove the 24 volt regulator, because it doesn't improve your power supplies stability or anything.
The rest looks good ;)
