Introduction: PC Remote Control

Picture of PC Remote Control

NOTE: This project was posted in 2006. Please view it as LEGACY project only. Because the software available changed dramatically also most of the new computers don't have COM ports anymore.

This project contains all about how to make a chip to control your computer remotely with almost any remote controller you can find in your house. Including, not only winamp control, but full computer control. You can control all your computer programs, procceses, sub-procceses etc.
All parts can by found at local radioshack shop. Everything cost abuot 20$ ,but whole project worth much more.
I'am using Girder software, newest version is 4.0. You can buy it at
You can also find this project in my Language (Lithuanian) at there.
Schematics are made by some guy name Igor. He also made plugin to program girder. OK thanks for Igor and let start making real good gifts!

Step 1: Part's List

Picture of Part's List

IC - TSOP1738
Resistor - 3k3 or 3k3 (SMD 1206)
Condensator - Ceramic 100nF or 2u2 (SMD 1206) (100nF - 10uF)
Zener diode - 5V1 or 5V1 (SOT23)
RS232 conection - 9pin Female

Step 2: Making

Picture of Making

Solder all parts on RS232 conection. There is 12 steps with explanation how to do that correctly.

Step 3: Software

Picture of Software

You can find full instructions in pdf file which is in help folder of girder. If you read the instructions you will see that is really easy to use girder and it's very functionaly. In there i just show how to turn on Igor plug in. We will need it for our chips. There is images with instructions above.

Step 4: Testing

Picture of Testing

To test your chip you just need to put it in you pc com port. Turn on Igor plugin settings and press ok. If no errors will be displayed you meet with success! If Hardware problem will be displayed check your soldering. Then if everything works fine try your chip with remote control. Press any button of remote controller and if green indicator will become yellow for a second that means it recived a signal.

Step 5: Shaping

Picture of Shaping

You can use hot glue for making a shape.

Step 6: Other Modifications

Picture of Other Modifications

Making the chip with smd parts is good idea. Becouse it become much smaler. You can solder cable to IC and prolong distance of reacting. If you maked that is better to place some magnets under IC it's more easyer to put it on pc box. There is some images with smd design and cable design.

Step 7: Overview

Picture of Overview

In this design hardware is very simple and cheap. I choose Girder becouse it is multilanguage program and it has free versions. It has a lot of hardware plugins too.
For better explanation how to use it read user manual. All remotes controllers works fine with this chip and program.
Just spend 20 minutes and you will have ultimate pc control.
It will cos 10$ - 20$ to you when analogs in stores cost 10 times more.
Have a good and happy New Year!
p.s. My kitty rocks!


i am mad (author)2014-03-22

I need help!!!!
I am student of EEE.My fifth semester is running and I have to make a project.I think I will make a pc remote.This project attracts me very much.can you please give answers of my following questions?-
1. Will I have to code any program for this remote?
2. From where can I download the Igor plug in?
3. Is the software girder and the plug in Igor is suitable for windows seven?
4. Can I control my whole pc with this remote control system or only any specific function such as a specific media player like winamp can be controlled by this control system?
please help me I need to discuss more and more about this project.I hope all of you give me more and more support.

i did this project nd connected to my pc.i installed girder 5.but the problem is i m unable to add me out plsss...

1105027 (author)steastiw2011-11-25

please help me out....i didnt find girder
please provide me some link of the software.....

will333333344 (author)2010-11-22

cant find girder 4 anywhere can anyone help?

saif (author)2007-03-15

how do i connect the remote to the sensor device ? do i have to go through the process of "adding device to universal remote" ?? or does it just connect ?? wanted to do the device within tomorrow ! please help. i have a sony remote that works with my tv, dont know, will that work or not, but one more thing, i dont have any a,b,c,d in the remote ! !

Zujus (author)saif2007-03-15

Ok that is it. I almost sure your sony remote works. THIS IS JUST EXAMPLE PICTURE FROM GOOGLE. I am using my tv remote now. :) If you have any software problems i can fix it. Just pm me or write comment here. ;)

varun.coolmax (author)Zujus2008-07-20

hi, awesome ible... tried this and Girder ( works fine with the Igor pluggin, but when i use my remote and try to map the keys to the just cannot diffrentiate between the keys...since the remote is detected i dont think that the hardware is wrong, i guess its something to do with setting in the software..please help !!!!. ... i tried it with diffrerent remotes and i face the same problem...

FYI....whenever i press any button on the remote it detects it as FFFF event...and hence it recognizes all the keys as same...please help....thanks

Danthaman (author)varun.coolmax2010-08-04

sounds like one of your components is wrong or connected wrong and is providing too high a voltage t the serial port (It could also be serial port config problems)

hmmm i just went to the site i mentioned below...and at the end it just gave the solution i was looking for (it was a one liner hidden somewhere in the text)..... anyways i was using IGOR plguin version 4.0.5 hence there was a bit of a change in the schematic... i.e we just have to Join pin 1 to pin 3 of RS232 anyways now i am good ...... working my computer from the far reaches of my room....Life is beautiful !!!!

akashigh (author)Zujus2007-06-04

please help me

cliffyd (author)2010-06-04

I really don't understand what this is? Help me please, are you saying you can sit back from the computer and push a remote button to turn it on, off, web, e-mail etc.? All in all not bad just explain the concept a bit better!

FuyuKitsune (author)cliffyd2010-06-10

It's a home-made IR sensor that plugs into the COM port. The software Girder takes IR signals from your remote and translates them into commands. You set the commands to whatever you want- the volume button could change computer vol, or channel change could be the arrow keys, run a program, cook your breakfast, anything you want it to do. Since Girder can run generic signals like this, I think that the same trick could work with a USB port.

cliffyd (author)FuyuKitsune2010-06-10

AHHHHHH Ic Ic very cool. Let me know some more we can exchange projects!

stormsirens2 (author)2010-05-11

 When Read the description of this, I LITERALLY slapped my face, but this a cool mod. Hope I can make it :)

tyldob (author)2010-01-13

Hi everyone, bit of a noob here. Does this have compatibility with linux, specifically Ubuntu? Or does anyone know how to make it be compatible with linux?


Colonel88 (author)2009-12-11

Cool, not that Condensator is also called Capacitor.

matstermind (author)2009-09-30

can i use any infrared receiver?

ravi.srt1 (author)matstermind2009-11-26


matstermind (author)ravi.srt12009-11-26

i meant can i use any type of receiver besides the TSOP1738

ravi.srt1 (author)matstermind2009-11-26

sorry buddy..but i am making my project using this receiver..if any possibility might be happen, i will write here as soon as possible..

mrknight410 (author)2009-09-23

can i use a 4.7k Resistor

Hexpigge (author)2009-08-25

lietuviskai? :D geras... :D

digitalenigma (author)2009-02-24

I had a hard time finding part IC TSOP 1738 so i decided to just buy one for $ 12.50 because i couldnt find the part,

could you just use a smaller one from another electronic item? does you have to point down at the computer?

can i use a different resistor? if so should i use less ohms or more?

Zujus (author)digitalenigma2009-02-24

I think, I can sell and ship you one for 10$, including shipping cost.

bladebaka (author)2009-06-08

does the female 9-pin go onto the monitor slot on a PC tower? and can you steal an IC whatever from an old VCR?

niranj_1994 (author)2009-05-19

You can use USB 2.0 to Serial RS232 DB9 9 Pin Adaptor/Converter to use this in usb port

drac76 (author)2009-05-16

hi! i have an old tp1556 from an xbox receptor, do you think i can use it? sorry for my english (french)

munchman (author)2009-03-13

Will this work through a Serial to USB converter thingy?

Zujus (author)munchman2009-03-14

It should do just fine, but please write if it does, I never tried one.

niranj_1994 (author)2009-03-06

You have told in parts list to use 3300 Omhs resistor,but why u used 3000 Omhs resistor

Zujus (author)niranj_19942009-03-06

I don't really remember, this was 2 years ago... Probably I couldn't find 3300 one, they both should work ;)

niranj_1994 (author)2009-03-06

plzzz reply me soon

niranj_1994 (author)2009-03-06

Do it works with girder 5.Also do it works with my philips tv remote

kawouter (author)2009-03-02

Hi, First of all: this is an awesome project! I'm planning to build one for my computer, because i use my computer as a tv as well :) So this is the perfect project for me. I have one problem. I cant find the 5.1 Volt zener. My university store does sell 5.6 and 4,7 V zener diodes. Can i use one of them for this project? (i really prefer buying there because they are really cheap, only €0,60 for the IR IC :) )

Zujus (author)kawouter2009-03-02

Thanks a lot! I believe that you can use 5.1v zeiner diode, it should work, and if you will have troubles finding tsop chip just write to me ;)

kawouter (author)Zujus2009-03-02

I have the tsop chip i want to know if i can use a 5,6 or 4,7 zener diode instead of the 5,1 version

Zujus (author)kawouter2009-03-02

Ooo, sry i misunderstood you, I think Both of them should work because voltage difference is not that great, i wouldl prefer 4,7v one. But honestly I don't really know :)just try ;)

kawouter (author)Zujus2009-03-03

Nevermind. I went to the university store today and i was lucky; they had one 5V1 left :) keep up the good work

kawouter (author)Zujus2009-03-02

what is the use of the diode in this circuit? wouldn't a regular diode work fine as well? (at least as long as your computer power supply is reliable)

niranj_1994 (author)2009-03-02

its supers and rocking da. it is also useful, its great .

nileshsonar (author)2009-03-02

from where can i get the girder v3.2 please tell me

Jakeg (author)2009-02-11

I have two questions: Does this have to be line of sight? And also How much money would you ask if I wanted to buy this without the hotglue?

Zujus (author)Jakeg2009-02-11

No, not directly no, think of it as tv remote, same range, same sight ;) I could make this for 20$ + shipping (<10$). I would include remote.

Jakeg (author)Zujus2009-02-11

Thank you sooo much for replying so soon. I live in The States and I was wondering if you knew how to make a remote with one button that turns off the computer using the adapter you made? I was just wondering.
