I live streamed creation of ROM module board in Eagle v5 running in MacOS X 10.4 on the one of the latest PowerPC G4 laptops that I own since 2007 ;) 

Later I edited archived videos to remove pauses and made it 8x faster:

Results (ROM 64K board) added to GitHub and here in Files:

Very cool video. Making PCB layouts is kinda relaxing.

Thanks, next video will be even cooler because it's true 1280x720 :)
YT is currently processing it...

Wow, somebody removed skull after I published this video :(

  Are you sure? yes | no

I lost a few skulls in the past day or so, too. Maybe a bug like the
"lost follows" that was happening a while back?

yes, may be it's some kind of glitch

Thanks for posting the video!  I wish there were more routing videos around.  It's a relaxing way to see how someone else approaches the problem and maybe pick up a few ideas.

Thanks. I'm pretty sure I made some mistakes obvious for professionals ( I'm not hardware professional - I'm a software guy - so I may not know something, but for hobby level it should be good enough ; )

  Are you sure? yes | no

Also I'll try better video quality in my future live streams - my current setup is a little bit overcomplicated :)

  Are you sure? yes | no

 For me, it is an iterative process doing hand routing and it take a very long time to get to a point that I am fully satisfied - also looking for stuff like high frequency digital signal return path that most seem to ignore.  My routing video done in real time would be really boring because it take days or even months to do it.

Probably more interesting thing to do is a hand routing contest/challenge with modern SMT packages.  :)

high frequency return path is easy: it's the unbroken ground plane that you have under each and every signal trace :-)
