I have an older Home-Electronics IRA infrared serial port receiver. The IRA has a green/red light indicating connection to the serial port. I've seen posts about setserial none (tried that, didn' work) and claims to revert to old versions of lirc (haven't tried that as I want to keep Mint like new). LIRC Setup; LIRC Setup. Execute the following command to display all the usb serial ports. Tira uses a short distance receiver which can receive IR signals.

Here are the parts I used, all of them were cannibalized from old projects or scavenged from the engineering lab except the IR receiver that I ordered from Mouser.
Parts List:
Vishay TSOP1138 IR Receiver
50v 4.7uF capacitor
4001 Diode
4.7K resistor
7805 voltage regulator (5 volts)

TSOP1138 IR Receiver: Most people use the Vishay TSOP 1738, but Mouser was out of those when I ordered and the 1138 is comparable... and it worked, so who cares : )
4.7uF capacitor: I used an axial 50v barrel (electrolytic) capacitor because I had one available and didn't want to spend 75 cents at Radio Shack. But, if you've got a 4.7uF ceramic disc capacitor, it would be a lot easier to fit inside the D-sub housing we're going to use. Also, since I used a 50v capacitor and we're only pushing 5v, it's going to have a pretty long rise time but it shouldn't affect the performance of our device too much.
7805 voltage regulator: I used a big one made by Motorola in the first one of these receivers I made and I had to clip the pins very short and clip and grind the top pole in order to get it to fit in the D-sub (see pictures of completed project). However, when I was digging around for pieces today, I came across a surface mount 7805 that I got from Texas Instruments as a sample years ago. It's tiny and perfect for this project. I'll definitely use it the next time I build one of these as it will cut the footprint of the circuit down tremendously. Both the large and small 7805's are labeled in the electronics closeup picture.
