IR Remote Control for Your Computer





Introduction: IR Remote Control for Your Computer

Use this R/C receiver for your computer to control all your things very good for people with htpc.

Step 1: Preperation

This is a very cheap receiver but can work with 99% of remotes and it cost me less than 5$.

IR receiver
Capacitor 4.7k uf 25 or 50 V
Resistor 4.7k
Diode N4148
7805 Regulator
D-sub 9 Connection (like on a old comp mouse)
D-sub 9 hood
pcb line board
3 line cable

Soldering Iron

Step 2: Solder the D-sub Connection

Solder 3 wires to these pins you might want to connect pin 7 as red because it is + and connect pin 5 as black ground and connect pin 1 as a green or yellow

Step 3: Solder the Rest

Solder all the rest like this diagram
you can also look at google far an etching diagram

Step 4: Finishing

if youve finished it should look something like this:
when your done plug it in to the computer and download or there are many programs and most are open source so look for your prefered program.

    I can't get LIRC to work. Tried all the troubleshooting advice, double and triple checked the receiver I built, but the software refuses to load. Can anyone give me advice please?

    I've made this thing but in a different fashion, the 7805 regulator shows the pins in and out in opposite direction in your description. Is there a purpose to this or is it a mistake? I've mirrored your diagram and then put the components in place.

    OK got it to work. Any Google search will tell you what the correct pin function is for the regulator; the image description in this DIY has in and out backwards. So assume that the diagram provided is a back view (soldering viewpoint). For everything else, I've made it as described.
    It works and that's all that matters; the IR unit I installed is a TSOP1836. If your PC has no serial connection then don't forget to order a cable to convert dsub 9 pin (male) to 10 pin main bord connection.

    Good job EEGG and thank you for this easy and working instructable.

    Hey. my pc dosent have a D-sub connection... only usb... what could i do to bypass this??

    You need to buy a PCI board DB9 /DB25 pins, is very cheap. Good Luck


    You can use a USB to Serial adapter.

    The Capacitor used here is 470 uf or 4.7k uf? i cant find the 4.7k uf..please help me

    Yes, dude. The capacitor is 4.7 uf, "four dot seven". I use 4.7 uf 25 V.

    I want to make this for my XBMC setup, will the IR reciever from an old mechanical mouse work for this project?

    can u give better shcematic plzzz, i cannot understandplzz reply

    just where do you plug this thing.

    A remote control receiver for your computer (Windows has only been coded for).

    It means you can sync up any remote you wish with it and give each button a different command and/or button

    Linux has a program for it as well, its called LIRC. Just google it :)

    Later that year i found it and have been loving it ever since :D

    i have everything set up on PCB, have the software installed too. i need a USB interface, nt a DB9. please help in this regard!

    Hey there,Nice instructable...Thanks for sharing..;)...I have 4 IR receivers bt i can't find its datasheet...its the SM0038....ive tried on same gud sites like theres nothing to do....Can you or any one help me finding it datasheet please....Or tell me if theres an alternative way of finding the pins configuration....Thanx in advance.....:).........

     if u still need it here is a pic on google of the datasheet or at least whats on the pins
