Building an ir receiver


I was looking for a commercially available IR receiver and came across this link.

http://lnx.manoweb.com/lirc/?partTyp...e=introduction

Now this looked like more fun than opening the box that came in the mail and connecting the contents to my computer. My only problem is I have never had a need for some of the components and do not know where to find them. I did find the TSOP 1738 IR receiver but I am having trouble locating the Sub-D 9-pin serial box and the Sub-D 9-pin female connector. The rest of the components Should be fairly easy for me to locate. Thank you.

Looks like I should have browsed the site a little better. If anyone else is interested here is a link where all of the components may be purchased with the part numbers.

edit: Seems they do not ship to the United States. Would anyone know where I could find the components in the US? Thanks.

BTW the serial box is in the US is called a backshell.
Post back if you need help finding parts etc.

Thanks for the tip. I was able to find everything at newark.com. This is my first attempt at making my own hardware but I do have some experience at soldering and the device appears to be pretty simple. I will let you know how it works.

OK. I now have everything together except the capacitor. I have no idea how to read the schematics and i do not know where to put the capacitor. Could someone please recommend a manual so I could learn how to read the schematics and let me know where I need to solder the capacitor? Thanks a lot.

I have figured out how to mount the capacitor but if someone could recommend a manual so I may learn to read schematics it would be greatly appreciated. Thank you.

A google for basic electronics should provide lots of information about schematics and basic electronic parts etc.

The positive lead of the capacitor goes inbetween the output of the 78L05 voltage regulator and the power input pin of the receiver. The negative lead connects between the reciever gnd pin and pin 5 of the connector. Take a look at the pictures.

Depending on the packaging of the voltage regulator (78L05) make sure you connect it up correctly. The flat spot will determine where pin 1 is located. http://www.ee.washington.edu/stores/...treg/78lxx.pdf
