Here's a fun little unit! 
I received a small 3.3mm red laser from Lasers4U
eBay Seller: lasers4u: Business Industrial, Electronics items on eBay.com
OMG! This thing is tiny! When I first opened the package, I just stared at it for awhile
It has its APC unit INSIDE this tiny assembly. That's right -- NO DRIVER NEEDED! Its lens is simply "slipped" over the front of the diode. It is powered by 3V and puts out 4mW. The unit was powered continuously for about 5 minutes with no heat sinking at all. When I turned it off, it wasn't even up to room temperature
Here it is on top of a penny so you can see the size of it. (Yes, I know that my macro shots suck)
Here is the obligatory beam shot (with visualizer)
The spot is a bit "messy", but for the size and integral lens, it will work just fine as a pointer or for special effects use. This shot is at 25 feet.
The spot is actually not quite as bad as this shot makes it look. I think that my camera is dying
The screen and pictures are starting to look like they are "melting."
All-in-all an interesting laser. If you are working on something small that needs "laser eyes" or need to include lasers into something, this would certainly do the trick.
Hmmmmmm -- a laser glove without all the bulk . . . . . . .
Peace,
dave
