Blog Goals or Lack Thereof

Dorothea Salo in Caveat Lector comments on how odd it seemed being asked how her blog was going. I think I would react the same way.

Ask how my music's going, or my filmmaking, or my morphological analysis of the Greek New Testament and I'd be able to tell you. They are projects, or at least interests manifesting as specific projects. Even the Poincare Project is foremost about me taking notes on my way to understanding the (possible) proof of the Poincare Conjecture. The use of the blog for those notes is largely incidental to that goal.

Blogging in and of itself isn't a project for me. I think that's largely because I don't have goals for it. Sure I track referrer logs and webstats, etc. Sure I get a thrill when Mark Liberman likes an idea of mine or Doc Searls doesn't. But they aren't accomplishments tracked against some schedule. I don't have monthly Scoble linkblogging targets.

Not that there's anything wrong with that. But for me, like Dorothea, blogging is scribbling. Occasionally making announcements, but mostly just scribbling.

Ground Loop

The last few days I've been reorganising my home office / recording studio (unfortunately, they are still the same thing).

When I plugged my Korg Triton LE into my Digidesign Digi002 I noticed the distinctive hum of a ground loop. I've never had to deal with a ground loop before. Basically they occur when one device's path of least resistance to the ground is through the audio cable. The result is a low hum at AC frequency (50Hz in Australia).

So I hopped on to the excellent home-recording mailing list to ask what I should do.

Rodrigue Amyot came to my rescue with some things to try. The first possible problem we identified was that the Korg's power cable is only a two-pin (what were they thinking!)

Another possibility Rod raised was mixing balanced and unbalanced devices. I don't know what the Korg is (my Roland keyboard definitely has balanced outputs) and I don't know what the Digi002 takes although I would guess balanced. My cabling assumes both are balanced.

Unplugging the power to the Korg still left the hum which suggested it wasn't a power ground loop problem after all.

Still working on the problem. Audio electrics is fun.
