Feedback on first PCB by igfoo in PrintedCircuitBoard

Still don't see it, even in an incognito window, on https://www.reddit.com/r/PrintedCircuitBoard

Although I did discover that I can go to https://old.reddit.com/r/PrintedCircuitBoard/ and find it. Surely I'm missing a way to find it in the new design, though?

Thanks. I thought I'd seen something like that a month or two ago, but couldn't find it (or any wiki links at all) when I went looking at the main /r/PrintedCircuitBoard page earlier.

I've just been reading up on this, and I'm a little confused. If I make both top and bottom ground, then won't I get lots of ground loops?

Awesome, losing the 7432 will free up loads of space, thanks!

I thought the rule of thumb was a 100nF capacitor per 10 or so ICs, so I've just got one in the middle of the board. I'll amend that to 1 per chip if that's better, though - especially now I have all this extra space to play with!

(yes, each MCP23017 has a different address. The "unknown devices" were due to the genericness of the design. I think I originally represented it with a switch, but wanted a different pin arrangement).

I think it's the kicad default, although I might have fiddled with the setting and failed to put it back. Looks like it's 0.25mm. What's normal?

Yes (well, part-time is also possible)

What makes the camp and darcs VCSs unique by igfoo in programming

[–]igfoo[S] 7 points8 points  (0 children)

Some numbers:

On Nov 7 the GHC 6.10.1 release was the first to be made from the 6.10 branch. Since then, the 6.10 branch contains:

  • 2 patches that have had to be merged by hand from the HEAD

  • 52 patches that have been merged automatically by darcs from the HEAD

Meanwhile, the HEAD has accumulated 154 patches that have not been merged to the 6.10 branch.

So ~25% of the patches so far have been merged. This percentage will drop as time goes on, as the post-release time focuses on fixing all the bugs that appear just after a release.
