Re: Problems with IR Board

I completely agree: IF there really is any kind of problem, I have complete confidence that FIRST and DSI will make it right.

But, WE have to help! By that, I mean this: Unless you are posting a fact, PLEASE label it as an opinion. At the very beginning of the BaneBots issue, there was a LOT of "noise" from people speculating, guessing an just plain writing what they thought was happening, but with little basis in fact. It was not until certain engineering folks started documenting facts using the scientific method (and photographs) that we got to the "root cause" and enabled BaneBots to address it.

Again: Post facts please, not opinion. If you don't know what happened, then just post your factual observations. If you speculate, then label it as such.

Tally so far:
358: LEDs flash during learning. After, either error light or nothing
456: Totally dead, 78L05 has no output
1357: Worked, then 78L05 fried. Maybe anti-static bag?
2144: Board works, LEDs do not light
2199: Error LED lights sometimes, not "0" (learn loop) LED


FYI: Current advice is NOT to repair the board if you suspect an issue, instead report your observations (to FIRST?). The regulator is a 78L05 in the standard TO-93 package, available almost anywhere (even Radio Shack - PM me and I'll mail you one). +5 VDC can be supplie, but the PIC will fry at 5.5, VDC, so try it only if you are really certain of your power supply...

Thanks,
Don
