Re: Problems with IR Board
 

Has anyone been succesful in getting a replacement board? Ours does not work, and when we took it to our lead electrical mentor, he pointed out several "dirty" solders on the board. We went to our local Radioshack to purchased every 5v reg that Radioshack had, but they were all too big.

Does anyone have a better source for a 5v reg? Is there a quicker way to get a replacement part?

For ours I just found an old 78L05 on some old broken piece of equipment here at school. I salvaged it from that. The board was up and running again in less than a min.

After Mr. Lotts and I tried replacing the regulator, we left it alone for a while.

Today, I tried testing our board again, and we got some jumping sparks from the pins of the regulator. This sort of thing didnt seem to happen with the original regulator. Im pretty sure its because the replacement one has to be lifted up off of the board, and attached with a few wires (since its beefier). After that, we imediatly shut it off, disconected the power... and backed away slowly.

Our team leader is suggesting we abandon this messed up board, and get a brand new one.

Later in the thread you say that you powered teh board from the back-up battery... check that the back-up batter is charged. The IR board has a 5v regulator on it so it needs at least 7V to "power up" the regulator.

A dead (dying) battery sounds like a likely villian.
