Druin board troubles

[mahuti]

Hm. Vexing.

Just got everything wired up. All was working just swell.

NOW THOUGH, the druin board is no longer working for me.

I've unhooked it from everything, wired it up seperate and it still doesn't work.

The CCW and CW are wired up start 1 and start 2 on the ipac which correspond to "1" and "2". The 5v and the ground are coming off of the optipac.  If I do a keyboard passthrough test with the iPac, it shows the CW and CCW are shorting, regardless of position. Any immediate thoughts, or links?

BTW, this is for the rotary hack on a 49 way. And it WAS working when I first hooked it up. I can't think of any major event that could have happened to screw it up.

I've tried flipping the 13 pin wiring harness in both directions and here's what i get on an Ipac test.

If the wiring harness is unattached, then I get no signals in the self test

If it's attached... I believe metal side down, then i get a test that shows nothing for 1 of the 12 positions, and both buttons depressed steady-on for the other 11 positions.

If the harness is metal side up, then I get nothing for 11 of the positions, and  for one of the positions it shows them both depressing in a-few-times-a-second intervals (not a steady-on short)

none of the rest of my controls are currently hooked up, so it's not like they're interfering in some way.

Tried to look up the faq at Druins site, and nothing jumped out at me... after doing a cursory search here, I don't see anything suspicious either.

The vexing thing is that it DID work as advertised. When I turned it a click, it spit out a button press. Then at some point, overnight, it arbitrarily stopped working. The only change that i seem to have made in that time frame was to unhook a usb mouse and keyboard I had hooked up. Hm. I haven't tried hooking them back up. Maybe I should.

fixed. I'll post some information tomorrow.

Never make a change to a working computer

Everything looked like it was wired up correctly, which made it rather hard to trace a problem. There may have been a short between 2 of my soldered contacts somewhere along the line, which I attempted to clean out. I was still having the problem after that, though. During the process of tracing the problem, I attempted to reprogram the iPac... I know it's not supposed to be programmable when there is a stuck key, but I think it got about half-programmed and couldn't get completely programmed since there was a stuck keypress. I had tried to restart the computer, which didn't seem to correct the problem.. it may have been that a wire came unattached shortly after restarting... so the problem seemed to change / get worse.

At any rate, I still don't know why the thing quit working, and I don't fully know why it began working again.
