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 www.promixis.com/.
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

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.
Thank you all friends.

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)  saif8 years ago
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. ;)
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 event..it 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
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 !!!!

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

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

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?

Cool, not that Condensator is also called Capacitor.

can i use any infrared receiver?
i meant can i use any type of receiver besides the TSOP1738
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..

lietuviskai? :D geras... :D
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, http://www.irblaster.info/receiver.html?gclid=CLnsz5GM9ZgCFQwNGgodN3NB1Q
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)  digitalenigma6 years ago
I think, I can sell and ship you one for 10$, including shipping cost.

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_19946 years ago
You can use USB 2.0 to Serial RS232 DB9 9 Pin Adaptor/Converter to use this in usb port

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

Will this work through a Serial to USB converter thingy?
Zujus (author)  munchman6 years ago
It should do just fine, but please write if it does, I never tried one.
niranj_19946 years ago
You have told in parts list to use 3300 Omhs resistor,but why u used 3000 Omhs resistor
Zujus (author)  niranj_19946 years ago
I don't really remember, this was 2 years ago... Probably I couldn't find 3300 one, they both should work ;)
niranj_19946 years ago
plzzz reply me soon

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 :) )
