Mark,

I'd be happy to help in the laser department. That's what I do, from frequency stabilized cavity lasers to bare laser diodes, and general experience with many others.

At the circuit level you can treat a laser diode much like an LED where the light comes out in a directional beam instead of a divergent beam. Cheap diodes are red. Some UV (deep blue) diodes can be salvaged these days as well.

What do you have in mind?

Folks:

I have some laser related questions. Who amongst us is a laser geek who
thinks that he/she knows enough about lasers to be dangerous? Or perhaps
knows of someone outside this group?

Someone had suggested to me to try to create tiny laser shows from my
lighted madallions.

Believe it or not, the dates on the site really are factual. The show opened January 24th and runs through March 24. The show is a companion to the larger faculty show going on in Eugene, so they had the reception now to not conflict with the opening reception of the main one.

The gallery's hours are Tuesday-Saturday Noon to 6.

Andrew,

Congrats on the opening!!!

For those of us that couldn't make the opening but want to see the show, 
do you know how long the show will be available at the White Stag/UO 
building?

The dates on the website (linked below) don't seem to match reality 
(unless an opening is now held in the middle of a show).   :)

Hey All,

There's a reception at the White Box (24 NW First Ave) for the UO Art

Department Faculty Show tonight 5:30pm-8:30pm.

I was commissioned to develop the motor control on Colin Ives' piece. I

think it's pretty cool. There's some other work in the show that I also

think my fellow dorks would enjoy.

More info here:

Hope to see you there.
