UIRT2 worked for 20 minutes, and then....
I received my UIRT2 assembled unit from Luc. I managed to solder the receiver to my wire, add the capacitor and ferrite core as recommended. The wire was 35ft, so I was worried, but it worked!! I was recording IR commands from an old remote!! Life was good. I even trained a button to shut down the computer. After the computer shut down, I spent a little time moving around the receiver, and bent the leads some. After this, I turned back on the computer and the UIRT2 WILL NOT WORK. Girder is not receiving any signals. I have unsoldered everything, resoldered, I bought new receivers and replaced the original receiver thinking that it might have gone out. Nothing. I have cut a 1 ft wire and added the connectors to it just in case the length was too much. Nothing.
One odd thing did happen. When I orginally found the device quit working, I unsoldered everything to reattach. When I did this, one of the metal arms from the ferrite core fell off. I found another item off of an old modem that looks like a ferrite core, but is about four times larger. It does not help. I am wondering if when I was adjusting the IR receiver and bent the leads if I broke the ferrite core and the thing I found is not actually a core. Would this explain the problems I am having? If so, where can I buy a ferrite core? PLEASE HELP ME!!!!!
