Still resoldering
After desoldering the whole thing and doing my best to clean out all the solder from the holes. I was still stuck with slightly obstructed access. Taking two cat5 wires and twisting the ends wasn’t resulting in a great deal of happiness. I just couldn’t get the wires in neatly without 2 or 3 rogue single wires going off in some tangent. So I went hunting for thiner, easier to use wire.
I found a great length of hard drive ribbon wire, must be a good 12″ length. So I’ve started rewiring all of the bits I desoldered. All the 4′s are done, with both the join and the spare length that goes to the breakoff from the shield. I figure tomorrow I’ll get the 2′s done and should be able to make progress with the break off. So I’m aiming for a Wednesday dry run plugging this baby in.
I hope your first test goes better than mine. None of my LEDs work, and some of my buttons trigger other buttons too…
Tomorrow night I’m gonna do some heavy multimeter work. I don’t see any shorts anywhere– but apparently I have them…

That’s what I was scared I’d end up with. Bear in mind it might not be shorts it might just be board to break-off bit of shield. Do you have all those wired up correctly? What did you work from (I still need a decent picture, I’m afraid of the one of bricktable, although it seems the best (when I get it working, I promise I’ll give back to the community by making diagrams of everything I’ve done.
Haven’t had a chance to do any more since this post, had a pet project online get picked up by cnet amongst others and it’s exploded. Went from 9 visitors on Monday to just over 30,000 in the last 36 hours. Everything’ failed, server, my code, my nerves, the lot.
I’ll probably spend some time tomorrow night, I need to get away from looking at code.
Hey so I’m still having troubles. But here’s some things you should check just in case. I had these wrong– and I fear I might have blown some things.
1. Make sure all your IC’s have the notches facing your capacitors (or the bout, bin, etc writings). I had my 164 reversed. That was my first problem.
2. Make sure your resistor network has the dot facing the 1 on the pcb. That was my second problem.
After I fixed those two I had all my buttons working, but the lights didn’t work. Then I turned it off and read on monome some more. I turned it back on and nothing works… So I’m stuck now.
I posted my problems on monome.org — maybe someone out there knows what to look for next.

Also– I went off the bricktable schematic and then this one too. http://post.monome.org/?PostBackAction=Download&AttachmentID=771
Congrats on getting picked up by cnet– but yeah I can understand the stress.
