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 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!

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: 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

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

Step 3: 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

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

You can use hot glue for making a shape.

Step 6: 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

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!

    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.

    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?
