Nothing too earth-shattering here, but I thought I'd share my experiences with giving a second life to a DX20 pen laser that had gotten to where it wouldn't turn on at all. This was a 2xAA pen laser, that at the time was $17. Seemed not bad for 20mW, and I got some fun out of it, but it was...

My wife shot this one - thought it turned out nice... http://www.zooomr.com/photos/Julie/3823115/ (Several rays through the wine with a long exposure.) Seems like most light or clear liquids give this effect. Anybody found any (like olive oil) that behave strangely?

This started over in another thread - I'm reposting it on its own. woop: I am actually thinking of rigging up a power curve setup. I don't have a laser power meter, so it will just be using a solar cell or phototransistor and having relative results, unless anyone has any experience calibrating...

Thought I might start a thread of unusual DIY laser cases. Actually I thought this might be the oddest for a while, but I just saw Phazonx's lantern  ;D Anyway, in keeping with the violet theme of the Blu-Ray diodes, here's the enclosure I'm using at least till something better comes along...

Scanner noob question here: I've got some low-speed galvos, which I'd like to use to draw some low point-count, low-speed patterns or text. I can hook them to my soundcard and display music in X/Y. Does anybody know of some cheap or free software to draw simple shapes or output ILDA via a...

After getting tired of wasting precious time and battery life trying to grip the AixiZ lens to focus it, I finally made this ugly little thing to provide a focusing handle.  Now I can point and focus with one hand. I cut this out of the back of a DVD box with scissors and an Xacto (it shows)...

I've got an "Open Can" LD that came from an 18x drive.  Been using it recklessly in a MagLite with no protection whatsoever.  I'm planning to pull it out of there and use Daedal's regulator circuit, but I'm wondering...  How does anybody find the max current for their diode without having two...

Spotted an interesting laser-show device for $14.95 over on ThinkGeek.com (search for "Pocket Laser Light Show"). Has anybody tried one of these? I've got one on order. I figure it might be interesting as it stands, or at least a cheap source of parts for a project.
