Surplus Gizmos in Portland, OR has some nifty yellow LED light wands for $3 a piece. These are about 30" long with 44 LEDs in a metal channel with a threaded fitting on the end. The LEDs are individually controllable (on/off) using shift-register-based LED driver chips, so they'll be easy to control using Swordfish or whatever. My partner picked up some of these for me while in was in Portland this weekend.
Seems like there are a lot of possibilities for these strips. How about a 60" POV display? Mount 2 strips on a hub for balance and display something awesome. Just don't get in the way - with the metal channel, getting smacked by one of these rotating at any speed with not be a good thing. Hazard lights for your car? An illuminated bargraph for your charity fund raiser? The theater marque you've always wanted? For three bucks, there seem to be many possibilities!
No difficulty at all getting this thing to come to life. I wrote some code for a shift-register-based bargraph from Sure Electronics years ago, and it just took a few slight mods to bring this to life. The biggest change was the output enable is high on the Sure, low on this unit. And changing the number of LEDs from 40 to 44.
